For years, Richard Fortey has found the uniqueness of fungi fascinating, from theirstrange forms, colours, reputation, rapid appearance and disappearance, to theiroften unseen role within the natural world. Close Encounters of the Fungal Kindtakes the reader on an enthralling journey through Fortey’s forays searching for the strangest, most extraordinary and most delicious species. Focusing on a selection of the larger fungi and a handful of microfungi, this charming book celebrates their profusion, diversity and importance.
Richard Fortey is a palaeontologist, nature historian, writer and presenter who worked as the Natural History Museum’s senior palaeontologist until 2006. Richard has served on the councils of the Systematics Association, Palaeontographical Society, British Mycological Society and more. He was elected as a Fellow of the Royal Society in 1997 and was awarded an OBE in the 2023 New Years Honours for services to palaeontology and geology.
We recently spoke to Richard about his book, his first introduction to fungi, his hopes for the future of mycological research and more.
The fungal kingdom is enigmatic, and in recent years it has gripped the attention of naturalists and the wider public alike, thanks to books such as this one. Do you remember your first introduction to fungi that sent you on this path of discovery?
As a child in Ealing on the fringes of London, we were lucky enough to have a large garden. I remember wondering at a great clump of glistening ink caps that appeared around a rotting stump – apparently overnight. In a day or two they had turned into a black soup. About the only book available then (I must have been about ten years old) was The Observer’s Book of Mushrooms and Toadstools, but I managed to identify our stump fungus as Coprinus micaceus. Finding others in the book became a challenge.
Fungi are everywhere, spores floating through the air, mycelial networks underneath our feet, and even in the deep ocean. Can you describe one of your most unexpected encounters with the fungal kind whilst compiling this book?
At my sister-in-law’s house in the rainforest of New South Wales, there were a host of fungi on the ground and on fallen trees. One of them growing on a trunk seemed to be an old and edible friend – the Oyster Mushroom. But when I went out in the dark, I was amazed to see it glowing with a ghostly greenish light. It was an Aussie double of our oyster, and a decidedly poisonous one. I used a photo of it taken by its own light in the book, and it still looks quite unearthly even now I know its identity.
You open the book describing an enchanting trip to the hills of northern Italy for a celebration of the foragers’ favourite, the Bolete. If you were to organise a mycologically focused celebration in the UK, which location would you choose?
When it is in top form it is hard to beat the New Forest for variety and number of species. Boletes used to abound there, and every kind of milkcap and brittlegill still does, and it is about the only place to see the extraordinary Nail Fungus emerging from pony dung.
In your book, you allude to the challenges of understanding taxonomy as a novice or intermediate mushroom fan through the lens of species names. However, you also highlight the importance of both binomial nomenclature and common vernacular names. Do you have a favourite species name, both scientific and common? And to take this further do you have any personal/pet names that you find yourself using for species?
The common small bracket that grows in tiers on dead logs is known as the Turkey Tail – and it really does look like a fanned-out tail of this big bird, with a neat white rim and a neatly zoned dark upper surface. The best scientific name really doesn’t beat around the nomenclatural bush, and it must be Phallus impudicus. The Stinkhorn indeed resembles an upright human reproductive organ and even retains a distinctively scrotal sac at its base. And it smells like rotting meat – the species name refers to that. As for pet names, my young nephew always referred to the beautiful but poisonous scarlet Fly Agaric as “Killer Diller” – and that name seems to have stuck.
As someone with a long career in the sciences, a lifelong mycologist, and an inspiring naturalist, which direction would you like to see mycology take in the next few years as it expands as both a field of research and a subject of interest?
There’s no question that DNA studies are taking mycology into a new direction – not least enabling us to ‘see’ fungi even without having their fruitbodies, for example, by sampling soils in different habitats. I believe that fungi are even better indicators of environmental health than our plants, and I really hope that conservation bodies – and farmers – realize that they need to fully recognize the contribution of fungi to total biodiversity. There are so many different species that identification often poses a challenge, and I personally welcome the development of apps to help, but there is no substitute for getting down on hands and knees on the forest floor. If a fraction of those who make birds their hobby took up mycology it would do no end of good to public awareness.
Finally, what’s occupying your time at the moment? Are you working on any other projects that you can tell us about?
I have had an ongoing project raising fungus gnats – which are also very diverse. One large fungus can feed a hundred tiny flies, and these in turn feed insectivores. Their importance in the food chain has been underestimated. Which species of fungi feed which gnats is still incompletely known, however this is the kind of project I can do in a small woodland like my own.
Close Encounters of the Fungal Kind is available from our online bookstore.
For many people, the mention of mushrooms conjures up images of stroganoff, druids, or damp housing. However, for those of us who are mycologically inclined, a vast kingdom of species, ecological interactions, and secondary metabolites awaits to boggle the mind. Fungi are everywhere, circulating through the air as spores, forming networks below our feet, and even influencing popular culture. But what is mycology?
Originating from the Greek language, mycology translates to the study of fungus. The term was first coined in the early 19th century, but the study of fungi goes much further back. The Greeks pioneered written fungal observations, initially through records of poisonings. They were also the first to attempt to classify mushrooms (fungi), albeit as plants with missing parts, a narrative that persisted until the late 1960s when the fungal kingdom was first described.
Since the Greeks, theories about fungi origins ebbed and flowed throughout written history. From a modern taxonomic standpoint, Linnaeus (the father of modern taxonomy who formalised binomial nomenclature) and his contemporaries were integral to mycology, describing groups (genera) that still exist today, such as Boletus and Agaricus – though these have been heavily adapted from the original classifications. However, at this time, mushrooms were still classified as plants within the subcategory of ‘Cryptogamia’, due to the lack of apparent sexual organs, a similar grouping to that of the Greeks. But is mycology solely concerned with mushrooms, colloquially known as toadstools, the enigmatic, ephemeral fruits of fungal species?
The short answer is no. Once thought to be asexual plants, mushrooms are actually the reproductive structures of fungal species that form networks of organic strands called hyphae, collectively known as mycelium. When two sexually compatible hyphal strands from the same species meet, they twist and writhe, forming a knot. It is from this mycelial joint enterprise that the mushroom fruits, hence the term ‘fruiting bodies’.
Boletus and Agaricus are prime examples of iconic toadstool-forming fungal genera. Once fully developed, the toadstool drops spores, either from pores (in the case of Boletus) or gills (as with Agaricus). These generaare members of Basidiomycota (the spore-droppers) that release spores to fall to the ground. The other major fungal group, Ascomycota, the spore-shooters, fire spores from specially adapted tissue into the wind. Fungi classified as Basidiomycetes do not exclusively form toadstools, there is a large variety of fruitbody formations, each with unique identifying features and characteristics. Examples include brackets, puffballs, earthstars, stinkhorns, corals, toothed fungi, jellies, rusts, and smuts.
Ascomycetes, the spore-shooters, exhibit a similarly large variety of fruit body forms. Many ascomycete fruit bodies are considered cup fungi, such as the morel – a forager’s favourite. Cup fungi belong to the Pezizomycetes. This subgroup also contains truffles, which are prized by chefs, foodies, and mammals of various sizes. Other intriguing forms include saddle-shaped fungi, earth tongues, and club- and finger-shaped fungi.
Ascomycete fungi are known for their propensity for parasitism and pathogenicity, such as the ever-fascinating Cordyceps (zombie ant fungus), made famous by The Last of Us, or Ergot(ClavicepsPurpurea), a plant pathogen. Ergot is hallucinogenic when consumed by mammals and most famously caused a ‘dancing plague’ among villagers in the early 20th century. Some fungi do not produce hyphae and therefore do not form mycelial networks or fruit bodies. A famous example of an Ascomycete fungus that doesn’t produce spores, mushrooms, or mycelium is yeast (Saccharomyces). Yeast is unicellular and present in the air and has had a dramatic impact on human societies via bread and beer, a winning combination.
Lichens represent a fascinating intersection of biology, ecology, and mycology. These composite organisms are the result of a symbiotic partnership between a primary photo-biont, typically algae or cyanobacteria, and a fungal host. The photo-biont contributes photosynthetic sugars, while the fungus creates a stable environment for the photo-biont to thrive. This mutualistic relationship is an ingenious ecological strategy that allows both partners to survive in diverse and often extreme environments. Interestingly, as mycologists delve deeper into lichen biology, more complex partnerships are being discovered. Notably, 98% of the fungi associated with lichens belong to the ascomycetes, the group of spore-shooting fungi, and almost half of all ascomycetes participate in lichen formation.
Let’s touch on slime moulds, another group commonly mistaken for fungi. These soil-dwelling amoeba, originally described as ‘fast-growing fungus’, were integrated into fungal evolutionary history until the 1970s. Slime moulds share similarities with fungi in their lifecycles and ecological niches, but despite their name and popular belief, they belong to a different kingdom altogether – the protozoan kingdom. It’s easy to see why they were once considered members of the fungal kingdom, as they ‘fruit’ under similar conditions and are often found on rotten substrates in damp forests.
The often-overlooked fungal kingdom has been a keycomponent to the development of life on earth andis often cited as one of the drivers for terrestrial evolution. Alongside its significance in evolutionary history, this unique kingdom has also benefitted humans for millennia andis expected to play a vital role in future healthcare, farming and food security. In addition to these significant contributions to civilisation, fungi are a delight to stumble across in the wild and are an object of beauty and wonder for many. Whether you are a seasoned mycologist, budding enthusiast or a complete beginner, fungi are bound to captivate you with their peculiarities –so why not head out this autumn, explore the forest floor, and see what you can find?

This blog focusses on forgotten species; those that are extinct, endangered or just urban, small and under-recorded. With climate change, habitat loss and invasive species threatening our native mammals, highlighting their importance is vital in driving their conservation, so we have chosen to spotlight three of the UK’s endangeredmammals, discussing their biology and characteristics, current conservation initiatives and what the future might look like for these animals.
Habitat: Freshwater, particularly streams and rivers near woodland.
Diet: Aquatic plants and grasses during warmer months, tree bark and shoots during winter. Preference for willow, Aspen, Alder and fruit trees.
Conservation Status: Critically endangered in England, endangered in Scotland.
Distribution: Free-range populations in the River Tay, River Otter and Knapdale, Scotland. Enclosed populations in Kent, Essex and the Forest of Dean. As of 2023, Scottish beavers have established 424 territories, housing up to 1,500 individuals.
Breeding: Between December and April. Birth in early summer of up to six kits, sexually mature at two years old.
Description: With distinctive orange, chisel-like teeth and a flat, scaled tail, beavers are instantly recognisable. Similar in size to a medium dog with shorter legs and a rounder body, the fur of a beaver ranges from brown to black. Once widespread in the UK, the Eurasian Beaver was historically persecuted for medicinal and cosmetic purposes. The species was hunted for fur, meat and the oil from its scent glands, resulting in extinction by the 1600’s.
Did you know? High iron content in the enamel of their teeth gives them their distinctive orange colour. This addition provides the teeth the extra strength that is required for felling trees and eating.
Conservation of Eurasian Beavers
Beavers are talented ‘engineers’, able to transform wetland and freshwater environments. Through the alteration and modification of these habitats, beavers can create complex wetlands, ponds and nurture more resilient ecosystems.Their dams provide a natural filtration system for freshwater landscapes and water quality is shown to increase as it passes through dam complexes, helping to reduce diffuse pollution in the area. Through improved water storage, beaver activities can also maintain water flow to drought-ridden landscapes, increasing the habitat’s resilience to climate change related conditions.
Environments altered by beaver presence host significantly higher diversity compared to those without. Tree felling can shed more light onto aquatic areas, encouraging growth of wetland vegetation. Feeding on larger, fleshy plants can favour smaller, slow-growing species in the surrounding habitat, leading to more abundant, diverse plant communities in the long-term. Species richness and overall abundance of small mammals, amphibians and bird species are also found to be higher in areas close to beaver dams.
After 400–500 years of local extinction, beaver reintroduction has been gathering traction in the UK. There are a number of reintroduction projects trialling their release, including the 2009 Scottish Beaver Trial in Knapdale Forest (which introduced around a dozen beavers to over four hectares of land) and the Devon Beaver Project which introduced one family group to an enclosed area in West Devon. England’s first wild project, The River Otter Beaver Trial, was founded due to the discovery of wild beavers in the region. This 5-year project observedeight family units over 28,700ha and is seeking to demonstrate the effect of beavers on other wildlife, local landscapes, water flow, water quality and local communities. Further reintroductions across the country have established both wild and enclosed populations of this keystone species.
Looking Forward
Reintroduction projects across the UK have been successful. Populations are breeding successfully and have been expanding their territories. However, there is cause for concern with the potential of conflicts to arise over land management. It is likely that, with expansion, there will be human-wildlife conflict with landowners and other stakeholders in the future. The impact of beaver activities on the environment can cause flooding of pasture, risk to crops and the felling of trees can cause harm to livestock and structures. Natural England has advised a paced approach to beaver reintroduction, minimising impacts to land use, infrastructure, livelihoods or environmental features while maximising benefits for the environment.
Habitat: Grassy banks along slow-moving rivers, canals and streams. Marshes, reedbeds, wet moorland, wetland.
Diet: Grass and waterside vegetation. Wetland plants in spring and summer. Roots, rhizomes, bulbs and bark in autumn and winter. Occasional invertebrates.
Conservation Status: Endangered in England and critically endangered in Wales.
Distribution: Found throughout mainland UK. Absent from Northern Ireland and most offshore islands. Estimated population of 132,000, range and numbers have declined by 94% from historical populations.
Breeding: March–October. Breed in spring, producing up to four litters a year.
Description: A small rat-sized rodent, the Water Vole has chestnut brown hair covering their entire body and tail, with a round nose and nearly hidden ears. This semi-aquatic rodent was historically widespread until the population saw a decline, resulting in nearly 90% reductions by 1998.
Habitat loss, degradation and fragmentation are key drivers of Water Vole declines in the UK. General infrastructure development, along with urbanisation of flood plains, have resulted in extensive loss of habitat for this species. Partnered with loss of vegetation and trampling around freshwater banks from grazing livestock, large areas of freshwater habitat are now unsuitable for voles. The unintended introduction of American Mink (Neovison vison) has also been pivotal in the collapse of Water Vole populations across the UK. Initially brought to England for fur farming, escaped mink have predated heavily on this species.
Conservation of Water Voles
Through grazing activities on grasses and rushes at the water’s edge, Water Voles manipulate their habitats, much like beavers but on a smaller scale. This manipulation can make space for a new community of wildflowers and grasses, attracting a host of invertebrate species to an area. As a valuable prey species, elevating Water Vole populations can support predators in the surrounding environment. Barn Owls (Tyto alba), Otters (Lutra lutra) and Pine Martens (Martes martes) are examples of native predators that would benefit from the repopulation of Water Voles.
A number of regional wildlife trusts have undertaken Water Vole recovery projects to support their repopulation in UK waterways. These typically involve recording and monitoring existing Water Vole activity, habitat enhancement, coordination of mink control, and in some cases, reintroduction of the species: 300 voles in the Yorkshire dales, over 600 in Essex, 200 in Gwent and over 1,000 individuals in Kielder Forest. The Forestry Commission has also pledged to make changes in Kielder Forest; improving the landscape by refraining from planting trees on river edges, providing much-needed habitat. In order to protect Water Vole settlement, the species is protected under the Wildlife and Countryside Act (1981), the UK Biodiversity Framework, and is listed as a priority species on the UK Biodiversity Action Plan.
Looking Forward
Reintroduction efforts across the UK have had mixed results. A period of growth was observed following initial releases in Nottinghamshire, which has now slowed. Overall occupancy from 2006–2018 has declined by 23%. It is thought that the continued pressure of habitat loss and mink predation is preventing populations from settling successfully. Responding to the poor establishment of Water Vole populations, recovery projects are enhancing existing freshwater habitat and building new areas to establish populations. Breeding and release sites will also be created to facilitate the successful reproduction of Water Voles in a safe environment, away from predation. In addition to habitat enhancement, more widespread mink control is also expected.
Diet: Small mammals, carrion, birds, eggs, fruit and invertebrates.
Conservation Status: Critically endangered in England and Wales, least concern in Scotland.
Distribution: Widespread and relatively common in Ireland. Populations recovering in the Scottish Highlands, some isolated populations in southern Scotland. Populations in northern England and Wales are fragmented and small. Populations estimated at 1,600–8,900 in Britain and Ireland.
Breeding: Mating season is during the summer months. One litter per year, born in March or April. Kits are fully grown at six months and sexually mature by three years old.
Description: Often confused with mink, Weasels or Stoats, the Pine Marten is a fellow member of the Mustelid family. Characterised by its chocolate brown fur and a distinctive, uniquely shaped light-yellow bib around the throat and chest, this elusive species has a long, bushy tail and large, rounded ears. Around the size of a domestic cat, Pine Marten are larger than both Weasels and Stoats and can be distinguished from mink by their chocolate coat.
Pine Marten populations underwent a major decline in the 19th century due to persecution by Victorian gamekeepers on sporting estates. Extensive habitat loss and fragmentation is another factor which contributed to the decline of these species in the UK.
Conservation of Pine Martens
The reintroduction of Pine Martens is favoured by many across the UK. The species is valued for their natural control of the invasive, non-native Grey Squirrel (Sciurus carolinensis), which can account for up to 14% of a Pine Martens diet. This predation allows the native, endangered Red Squirrel (Sciurus vulgaris) to take hold. Eradicating competition from Grey Squirrels, and reducing the risk of the squirrel pox virus, has allowed the Red Squirrel to successfully repopulate areas around Pine Marten territory.

The Two Moors Pine Marten Project, the South East Pine Marten Restoration Project,Back From the Brink and Martens on the Move are programmes founded to support the expansion of Pine Martens in England. A total of 35 individuals have been relocated from Scotland to the Forest of Dean and the Wye Valley, and further reintroductions are expected to take place on Exmoor and Dartmoor National Parks later this year. Other projects aim to facilitate reintroductions through the enhancement of key habitats (Martens on the Move) or to undertake surveys and monitoring to inform on species distribution (Back from the Brink).
By 2017, around 50 Pine Martens had been relocated to woodland in mid-Wales from their original home in Scotland. The population was radio tracked throughout the first year, which monitored their movement and behaviour. The group have established a viable population, breeding every year since reintroduction.
Looking Forward
The future of Pine Martens in the UK is promising. Monitoring of existing projects shows successful breeding and expansion from Scotland into Northern England. It is expected that more Pine Martens will be released in the Forest of Dean, in addition to an estimated 40 individuals to be released with the Two Moors Restoration Project in autumn 2024. It is hoped that, with further expansion, populations may link with Welsh Pine Martens, boosting connectivity and genetic diversity.
However, as populations continue to expand, there is an increasing risk of conflict. With greater human populations, greater infrastructure, and greater exposure to protected species, concerns may arise among the public. The species are known to find their way into chicken coops and pheasant pens, damaging livestock and causing conflict with local farmers. The Vincent Wildlife Trust, Natural England and NatureScot recommend sufficient Pine Marten monitoring, active engagement and open communication with stakeholders to mitigate potential conflicts before they arise.
Each year, Butterfly Conservation urges the public to venture outdoors and record their local lepidoptera populations with the Big Butterfly Count – a UK-wide survey aiming to assess the health of butterflies and day-flying moths. The count involves recording the number and species of butterflies in a chosen area for fifteen minutes and uploading results to their official website.
There are around 130 day-flying macro moths and 59 species of butterfly in the UK. These highly sensitive animals are key indicators of environmental health and play a crucial role in pollination across the country. The latest State of the UK Butterflies report, an assessment on British butterflies, found that the group has declined by 80% since the 1970s. The Big Butterfly Count allows the health and trends of these species to be assessed, improving our understanding of their conservation and threats.
This year’s count took place between Friday 12th July and Sunday 4th August, and the results from nationwide counts can be found on Butterfly Conservation’s interactive map. Over 140,000 counts were taken during this time, recording nearly 1,000,000 butterflies. Gatekeeper (Pyronia tithonus), Meadow Brown (Maniola jurtina), Large White (Pieris brassicae), Small White (Pieris rapae) and Peacock (Aglais io) butterflies were the most recorded species across all data points, accounting for over 670,000 sightings.
This years count revealed the lowest numbers on record, and has led to the announcement of a nationwide ‘butterfly emergency’. On average, seven butterflies and day-flying moths were seen per count, half of last years average. This years count observed significant downward trends in the group, with around 81% of species showing declines, and 600,000 less butterflies recorded than last year (which equates to around a third of 2023’s total observations). 9,000 counts did not record any butterflies, which is the highest number recorded in the history of the count.
We participated in the Big Butterfly Count this year, and are excited to share our results below.
The National Trust has reached a significant nature target a year early. The charity strived to restore 25,000 hectares of crucial habitat across the UK by 2025, including peatland, woodland, wetland, meadow and saltmarsh, and succeeded in doing so in August this year. The restoration comes as a response to climate change and national conservation targets and seeks to expand meadows and woodland to create a connected network for wildlife.
Eighty Water Voles have been released to restore ancient landscapes in Cornwall. Considered ‘ecosystem engineers’ these mammals are known to positively impact soil health and plant diversity through grazing and enhanced nutrient transportation. The voles were released along the River Fowey to improve the surrounding wetland habitat created in 2022.Afurther 120 have been released near Megavissey, and more releases are planned for spring next year.
Three years of restoration work have seen the return of endangered birds in Hertfordshire.Work has come to a close on the Ashridge Estate, the largest woodland maintained by the National Trust – over 24 hectares have been restored by clearing dense areas of plantation, which has allowed more light to reach the ground through the canopy. Greater access to sunlight has improved biodiversity and the availability of food sources, andthe clearing will provide suitable conditions for many breeding birds, including Spotted Flycatchers which have been spotted on the estate after several years of absence.
Conservation
Conservationists are relocating Florida’s Queen Conches in a bid to support theirreproduction. This iconic mollusc has undergone significant declinesin recent years, accelerated by increasing ocean temperaturescausing lethargy and infertility for individuals residing in warmer, shallow waters. By relocating these gastropods to deeper, colder waters, researchers are providing new mating opportunities in a more suitable environment. Listed as threatened under the Endangered Species Act, this project is helping to ease reproductive pressures on this species.
In August, the UK government announced a goal to end all badger culls by the end of this parliamentary run. The newswas announced as part of a new scientifically–informed and evidence-based eradication strategy for bovine tuberculosis, which hopes to eradicate the disease by 2038. In the past decade, over 230,000 badgers and 278,000 cattle have been slaughtered, costing the taxpayer over £100m each year. Badgers will instead be vaccinated and released, and a dedicated task force will be formed to ramp up vaccination rates.
Wildlife
Five species of seabird have been added to the UK red list. Arctic Tern, Great Skua, Leach’s Storm Petrel, Common Gull and Great Black Backed Gull have joined the list of species most in need of conservation, followingpopulation declines due to a number ofpressures including climate change, habitat lossand unsustainable fishing. Over 30% of all British birds are currently on the list including Kittiwakes, Puffins and Arctic Skuas, among others.
Researchers have found promise in the medicinal plants used by critically endangered Western Lowland Gorillas in Gabon. The group studied the tropical plants eaten by gorillas in Moukalaba Doudou National Park and found four trees also used by localhealers. They are high in antioxidants and antimicrobials, and one tree is a promising candidate for tackling superbugs. All four species (Fromager trees, Fig Tree, African Teak and Giant Yellow Mulberry) show activity against a resistant strain of E. coliand contain chemicals with medicinal effects useful for treating a range of ailments.
The collectives formed by social insects fascinate us, whether it is bees, ants, or termites. But it would be a mistake to think that the individuals making up such collectives are just mindless cogs in a bigger machine. It is entirely reasonable to ask, as pollination ecologist Stephen Buchmann does here, What a Bee Knows. This book was published almost a year after Lars Chittka’s The Mind of a Bee, which I reviewed previously. I ended that review by asking what Buchmann could add to the subject. Actually, despite some unavoidable overlap, a fair amount.
Though I will leave a comparison and recommendation for the end of this review, I can already tell you that What a Bee Knows is a different beast altogether. Buchmann’s approach to convincing you that bees are sophisticated insects is to provide a general and wide-ranging introduction to bee biology, telling you of all the things they get up to.
What makes this introduction accessible to a broad audience is that Buchmann goes back to first principles. For starters, what even is a bee, and where did they come from? You might not realise that they evolved from carnivorous predatory wasps and likely did so some 130 million years ago, not long after the evolution of flowering plants. Another basic aspect Buchmann highlights is how myopically focused we are on social bees. The thing is, 80% of all 20,000+ described bee species are solitary. Their biology is the more representative one and Buchmann discusses examples from their lonesome lives throughout this book, many based on his observations working in the Sonoran Desert of Arizona and elsewhere. He reminds the reader that “we should not think of honey bees as the pinnacle of bee evolution toward which all bee species strive” (p. 32). Theirs is the exception; a high-risk, high-reward strategy to making a living on this planet.
This approach of introducing basic concepts is applied throughout the book. Thus, we get a brief tour of the gross anatomy of the bee brain, but not before Buchmann explains the basics of the human brain and the structure and workings of neurons. An introduction to sexual selection prefixes the discussion on the many sexual escapades of bees: from scramble competition in cactus bees involving bee brawls (which is exactly what it sounds like), to hilltop lekking in carpenter bees, to alternative reproductive tactics with different male morphs in Centris pallida. Bees can learn to solve problems, improve their performance, and even learn new tricks from other bees, but what is this process called learning, and how widespread is it? Similarly, chapters on sleep, pain, and consciousness all first discuss more broadly what these are and what we know about them in humans and other vertebrate and invertebrate organisms.
Buchmann is a pollination ecologist by training and he cannot help but indulge in a long chapter on pollination. He is on form here and gleefully reminds readers that, next to billboards for pollinators, “flowers are unabashedly plant genitals exposed on a stem for all to see” (p. xiii), while bees act as “surrogate flying flower penises” (p. 78). Though it is traditionally held up as a wholesome form of mutualism, it has elements of an arms race too. As Jeff Ollerton also points out, active pollination, where a pollinator deliberately places pollen on a flower’s stigma, is extremely rare. Rather, the norm is that both pollinators and flowers have their own interests (food and pollination), at heart first and foremost. Sometimes both parties will benefit, but this is not a given. Orchids trick male bees into pseudocopulation with flowers that look and smell just like female bees, dusting them in pollen in the process without offering any nectar. At the other extreme, carpenter bees have become nectar robbers, using their jaws to cut into flowers at their base to access nectar, and thus not providing pollination services. And here is an interesting recent development: studies on the bee microbiome suggest that bees derive some of the microbial life that populates their gut from the flowers on which they forage. In some cases, the proteins contributed by flower microbes might be more nutritious than the pollen grains.
A chapter on sensory biology is, of course, obligatory and Buchmann covers all relevant topics: the trichromatic vision of bees that extends into the ultraviolet, their perception of polarized light used in navigation, their excellent smell, their hearing (which is more a detection of pressure waves at close range), their taste and tactile senses, their to-us-alien detection of electrical charges (and the electrostatic footprints bees leave on flower petals after a visit), and the still contentious topic of magnetoreception. What was new to me is that the two mobile antennae produce a three-dimensional impression of an odour field, and some nifty experiments that involved crossing their antennae resulted in bees persistently walking away from the source of a smell, indicating that they really do smell in stereo.
Though an accessible and enjoyable romp into bee biology, I do have a few minor quibbles. There is a limited number of general black-and-white illustrations and photos, and the reproduction of the latter is so-so as this is a print-on-demand book. And though What a Bee Knows avoids getting too technical, I do feel that in some places Buchmann wanders a bit off-piste from exploring the inner world of bees into more general fascinating tales of bee biology. Nevertheless, the book achieves its mission of instilling a renewed respect and a better understanding of how bees live.
Having now reviewed both Chittka’s The Mind of a Bee and Buchmann’s What a Bee Knows, how do they compare and which one should you read? Both books broadcast the same message loud and clear: bees are darn sophisticated creatures and even individually are far smarter and more capable than you might initially give them credit for. As mentioned, Buchmann goes back to first principles on many topics and wanders into bee biology more generally, while I remarked that Chittka delivers an information-dense book with numerous explanatory illustrations that is very focused in its approach, talking bees, bees, and the occasional other hymenopteran. Consequently, Buchmann does not delve as deeply into many subjects, though he does discuss some experiments in detail (including Chittka’s work on several occasions). My recommendation would be that general readers with little background in biology or entomology pick, or first start with, What a Bee Knows. Biologists, in particular entomologists, might want to skip straight to Chittka’s The Mind of a Bee and get stuck in the wealth of detail there.
What a Bee Knows by Stephen Buchmann is available from our online bookstore.
Here in the UK, we have 11 species of grasshopper and 23 species of cricket (around ten of these being bush-crickets), both subfamilies belonging to the order Orthoptera. Although similar in appearance, the two can be separated by their antennae – grasshoppers have short, stout appendages and bush-crickets have longer, thinner antennae. Bush-crickets also have a larger body size than grasshoppers, growing up to 5cm in length, and females have a distinctive ovipositor used to lay eggs.
Here, we look at a few species of grasshoppers and bush-crickets found in the UK, detailing ways to ID them and where they can be found.
ID Notes: Up to 2.5cm in length. This grasshopper is usually a mottled brown colour, but can vary from brown to grey, orange and purple. It has barring on the sides, and a very hairy underside which is the most straightforward way to identify this species. It is winged and able to fly. Their song consists of short, single chirrups repeated at short intervals.
Distribution: Common and widespread throughout Britain. Common Field Grasshoppers can be seen from May to October on short vegetation in dry, warm days. They can be found in grassy areas including farmland, grassland, heathland, moorland, towns and gardens.
ID Notes: Up to 2.3cm in length. Meadow Grasshoppers are usually green in colour, with some individuals brown or pink-purple coloured (pictured above). The wings are often brown and are long in males, whereas female wings are short and do not reach the end of the abdomen. This species has distinctive black knees and a dark brown stripe running across the flank to the eye. They are similar in appearance to Common Field Grasshoppers, but lack a hairy underside, which can be used to distinguish them from one another. Their song is a burst of around ten chirrups, making a ‘rrr’ sound.
Distribution: Common and widespread throughout Britain. Meadow Grasshoppers can be seen from April to October in damp pastures with long grass. They can also be found in meadows, grassland, heathland and moorland.
Common Green Grasshopper (Omocestus viridulus)

ID Notes: Up to 2.3cm in length. As the name suggests, this species is mostly green in colour, but males can also be olive brown. Lines on the shoulders are incurved and white or cream in colour. Common Green Grasshoppers are winged and can fly, but their wings do not exceed the body’s length. They produce a long, loud ticking song which can last for 20 seconds or more and is reminiscent of a fast-paced freewheeling bicycle.
Distribution: Common and widespread throughout Britain, although a little patchier in the lowlands. This species appears early in spring and can be seen from April to September. It can be found in coarse, moist grass in meadows, woodland rides, hillside pastures and farmland.
ID Notes: Up to 2cm in length. This small grasshopper is most easily identified by its antennae – males’ are club-tipped, and females’ have a thickened tip. The body has several colour variations including green, brown, grey and orange. Their song is a repetitive ‘zrr’ ‘zrr’ sound lasting around ten seconds before stopping abruptly.
Distribution: Widely distributed across the UK, but uncommon. Mottled Grasshoppers can be found from April to October in areas of dry, short grass with access to rocks or bare ground, including grasslands, heathland and old quarries.
ID Notes: Up to 1.7cm in length. This species is the UK’s only native, arboreal cricket. It has a slender, lime green body with a yellow-orange or brown strip running along its back. Both sexes are fully winged, with wings reaching the end of the abdomen. Females have a long, upturned ovipositor and males have a pair of shorter, rounded claspers. The males do not produce a song, but instead drum their hind legs on nearby leaves.
Distribution: Common, found in England and Wales. The Oak Bush Cricket is common in the midlands and the south but is absent further north. It can be found in the canopy of mature trees in woods, hedges, garden shrubs and other deciduous trees from June to November.
ID Notes: Up to 2.1cm in length. This species is typically reddish to dark brown, with occasional yellow green through the abdomen and a paler area along the top of the thorax. It has very small forewings and long, hair-like antennae. Females have a large, upcurved ovipositor.
Distribution: Fairly common in central and southern England and Wales, where it can be found in woodland, hedgerows, grassland, farmland, towns and gardens. It can often be spotted in large numbers around bramble patches, where they are basking in the sun.
Roesel’s Bush Cricket (Metrioptera roeselii)

ID Notes: A short-winged and usually flightless species, Roesel’s Bush Crickets are typically dark brown or yellow in colour, sometimes tinged green. They have a green face, slightly orange legs and a cream-coloured margin to their thorax, with two or three yellow spots on the side. Their monotonous song is recognisable for its long, mechanical sound.
Distribution: Common, found mostly in the southeast of the UK, but currently expanding its range north and west. This species can be found from June to October in rough grassland, scrub, salt marshes and damp meadows.
ID Notes: This large bush-cricket can easily be distinguished by its size, growing up to 7cm long. It is a vibrant green with an orange-brown stripe running the length of its back. Their wings are typically longer than the abdomen, and females have a long, downward curved ovipositor. This species has a loud, long song which sounds like a high-pitched sewing machine running continuously.
Distribution: Common throughout south England and Wales. It can be found from May to October in scrub, woodland, grassland and heathland, with a preference for light, dry soils.

If you look under logs, stones or through piles of leaf litter, you may find a Myriapod (a type of arthropod with many legs, related to insects and spiders). Although these misunderstood animals may strike fear in some, these invertebrates play a vital role in maintaining our ecosystems. One of their main roles lies in nutrient cycling, where they feed on organic matter and detritus, breaking materials down into a simpler form and thus releasing nutrition back into the soil. They also play an important role, both as predators and prey, in the ecosystem’s food chain and are often celebrated for their effectiveness as a natural biocontrol agent.
The UK has more than 50 species of centipede. This group are generally carnivorous and have around fifteen pairs of legs, with one pair present on each body segment. They have large forcipules, a pair of pincer-like, modified front legs that are used to inject venom into their prey. There are around 65 species of millipede in the UK, which can be distinguished by their shorter, more clubbed antennae, the absence of forcipules and their tendency to have two pairs of legs on most body segments.
Here, we look at a few species of centipede and millipede that can be found in the UK, detailing ways to ID them and where they can be found.
ID Notes: Also known as the Brown Centipede, Lithobius forficatus is one the largest centipede species in the UK, growing up to 3cm in length. They have long, thin segmented bodies that are a reddish-chestnut brown colour. Each segment has one pair of legs, with 15 pairs in total. They have long antennae and an elongated pair of back legs, giving the illusion of a second pair of antennae at the rear of the body. This species is best identified by thorned projections on the outer edges of the 9th, 11th and 13th segments.
Distribution: Very common and widespread across the UK. This species can be found year-round but is most numerous in spring and autumn. They can be found in a variety of habitats, including woodland, grassland and gardens, and will spend most of the day nesting in soil or sheltered areas under stones, bark or dead wood before emerging at night to hunt for prey.
ID Notes: Similar in colour to the Common Centipede, Lithobius microps is a ground-dwelling species that is usually chestnut brown in colour, although red and orange varieties can also be found. It is much smaller than its common cousin, reaching around 1cm in length, and its 15 pairs of legs are slightly shorter and paler than those of the Common Centipede.
Distribution: Fairly common in the south of Britain. This fast-moving species can be found year-round in gardens and bare soil in rotting wood and under rocks and stones.
ID Notes: Measuring up to 3cm in length, this small, yellow-brown centipede is easily distinguished by the banding on its legs – these alternate pale and dark, are usually brown in colour and are more obvious on the rear pairs. It has a dark band running centrally along its back and much larger jaws when compared to other Lithobius species.
Distribution: Widespread and common in the UK. It can be found year-round living under stones and decaying plant matter during the day, and is commonly found in garden compost heaps.
ID Notes: This millipede grows to around 2.5cm in length, with a width of 4mm. It has a long, flat body with around 20 body segments, each containing between one and two pairs of legs. It is orange-brown in colour and has numerous off-white coloured legs.
Distribution: Widespread and common in the UK. They can be found in almost any environment in which millipedes occur, with frequent sightings in woodland under dead wood and leaf litter.
ID Notes: Up to 3cm in length, this species is one of the largest millipedes found in Britain. It is thick and cylindrical in shape, usually dark brown to black in colour. It has orange coloured stripes running the length of its body on its back, but these can sometimes appear as a series of orange patches.
Distribution: Common and widespread throughout Britain and Ireland. The Striped Millipede can be found year-round in meadows, fields and woodland under leaf litter and logs. It is also known to climb on walls and trees to feed on algae and can be found during the day.
ID Notes: The White-legged Snake Millipede can grow to around 6cm in length. It is tubular-shaped with a shiny black body and contrasting white legs, of which there are around 100. Immature millipedes are brown, often with pale, longitudinal stripes down the back. It has a pointed telson (legless tail segment) at the end of its body.
Distribution: Common and widespread in the UK. This species can be found year-round in most habitats containing millipedes, including woodland and gardens, or areas with rocks or rotting vegetation to provide cover.

Britain’s rarest plant has been rediscovered in Britain for the first time since 2009. Having been declared extinct after a 22 year absence, a single Ghost Orchid was recently discovered by Richard Bate who has spent the last 30 years searching for it, marking the end of the plant’s lengthy absence. The location of this rare specimen will remain concealed to protect the delicate flower from trampling and poaching, while scientists work to protect the orchid from natural predators and grazing animals.
DNA analysis is helping to eradicate the American Mink from East Anglia. This invasive species has been decimating Britain’s Water Vole and seabird populations since the 1970s, and authorities are now utilising DNA technology to manage their population. Using this key technology, the Waterlife Recovery Trust can estimate relatedness between individuals, identify how far animals may have travelled and pinpoint access routes to remove re-entry points, thus eradicating populations within the project area. The trust has successfully cleared East Anglia of this invasive species, and have seen no signs of mink reproduction in the core project area, resulting in a distinct increase in Water Vole presence.
The world’s fish stocks are in a worse state than previously thought. Research suggests that the scientific recommendations informing fisheries policy are too optimistic and that more global fish stocks have collapsed or are overfished than originally estimated. The study suggests that around a third of ‘maximally sustainably fished’ stocks are actually overfished, which can lead to phantom recoveries where declining stocks are thought to be recovering. The study calls for simpler, more conservative stock assessments and management that are quantified based on realistic models.
Wildlife
An RSPB survey has revealed a hotspot for a threatened species. Data collected from April to June across East Yorkshire and Lincolnshire has found 420 breeding pairs of Redshank on the Humber Estuary, a hotspot for these threatened birds. With a total population of 22,000, this environment holds around 2% of the entire population and is now considered a highly important area for this species of conservation concern.
A network of wildlife charities is calling for the release of beavers across the UK. Following a successful summer of breeding, the trusts have seen an upsurge in kit sightings throughout the UK, sparking a call for further management and strategy surrounding the species. These organisations are calling for the government to produce reintroduction strategies to facilitate their return across the UK and are urging authorities to allow illegally released beavers to remain in their release sites, of which there are over 1,000 in Scotland.
Environment
Countryside river testing reveals pharmaceutical pollution across the UK. Researchers from the University of York tested 54 locations and revealed contamination at 52 sites, with the most common pollutants including antidepressants, antibiotics, antihistamines and diabetes treatments, among others. The study found that rivers in the Peak District were more polluted than samples taken in London, with a total of 29 active pharmaceuticals detected in the region. This discovery marks concerns for antibiotic resistance, human health and concern for the health of freshwater organisms residing in the waterway.
Hoverflies of Britain and Ireland is a beautifully illustrated photographic field guide that details the hoverfly species readily available in Great Britain. This revised and updated third edition details 13 additional species and features more than 840 stunning photographs, alongside a host of other improvements to aid reliable identification. As such, this is the most accessible, authoritative and easy-to-use guide available, and a must-read for all entomologists and naturalists alike.
Stuart Ball and Roger Morris have been running the Hoverfly Recording Scheme since 1991 and published the Provisional Atlas of British Hoverflies in 2000. Stuart and Roger both worked as entomologists for the statutory nature conservation agencies, are both active members of the Dipterists Forum, a society that promotes the study of flies, and have subsequently run many hoverfly identification courses prior to their retirement.
We recently had the opportunity to talk to both Stuart and Roger about the book, including how they first became interested in working with hoverflies, where the ‘new species’ that are now detailed in the third edition have come from and more.
Firstly, can you tell us a little about yourselves and your history of working with hoverflies?
In the late 1980s and early 1990s, we worked for the Nature Conservancy Council’s ‘Invertebrate Site Register’ and were active entomologists with a broad interest in flies. Alan Stubbs, our boss at the time, was looking to re-vitalise the Hoverfly Recording Scheme following Philip Entwistle’s retirement and twisted our arms to take it on. The idea was to combine Stuart’s interest in computing and data interpretation, and Roger’s interest in hoverflies, to try to get the scheme back off the ground. At that time there were about two cubic metres of record cards and about 50,000 computerised records. We took the project on, knowing that we would have to computerise those cards, check the existing computerised data and draw in data from numerous other datasets. Little did we realise what it would entail and how it would change our lives! We produced a provisional Atlas in 2000, a second one in 2011 and now have maps available online. Although we are still running the scheme, we do want to see it safely transition to a new generation before we become too long in the tooth!
You are both involved in organising and managing the database of the Hoverfly Recording Scheme. Can you tell us a little bit about it and why the scheme is important?
We split responsibility – Stuart manages the database and deals with data import and final validation processes, whilst Roger deals with day-to-day contact with recorders, including verification of iRecord data and active engagement via the UK Hoverflies Facebook group. The dataset now comprises over 1.8 million records and is the largest dataset for an insect group, except for Lepidoptera and Odonata. The size of the dataset, combined with the unique ecological significance that arises from their various larval feeding strategies, makes hoverflies an excellent subject for many lines of research. The most obvious one has been interest in pollinators, but there are growing avenues of interest in hoverflies because they are sensitive to climate change and also because they are often highly habitat specific. Scheme data is also used in the triennial ‘State of Nature’ reporting.
There are 13 additional species included in this updated edition. Where have these ‘new’ species come from?
When we started work on the new edition there was scope to expand the book, but obviously much less scope to completely re-organise its structure. The species chosen were mainly included because experience has shown them to feature among the species whose photos are posted online and, therefore, people want to know about them. One big change we have made has been to make sure that all Eristalis species are covered and that we have a key to assist in their identification.
The third edition includes a new section on putting data to good use. Why was this important for you?
Our objective from the onset has been to produce a book that is somewhat different from a traditional identification guide. We wanted to make sure that readers thought about both the animal they saw and its larval biology. Moreover, we wanted to encourage high-quality recording. Our background in nature conservation has taught us that the biggest impediment to insect conservation is a lack of reliable data. So, we felt it was necessary to show readers how records might be used and what messages they can convey. The use of models to investigate aspects of wildlife biology and conservation is relatively new, so showing readers that data can be used for a lot more than just ‘dots on maps’ is essential if we are to foster an ongoing high-quality recording community.
Traditionally, hoverfly guides use dichotomous keys as the primary aid for identification. What challenges did you face in producing an identification guide based on photographs and why did you feel that a photographic guide was the right choice for this book?
When we originally developed the book, it was not our intention to replace the existing monographs which include full keys, such as British Hoverflies (Stubbs & Falk 2002), Hoverflies of Northwest Europe (van Veen 2010) and the newer Hoverflies of Britain and North-West Europe (Bot & van de Meutter 2023). Our intention was to produce a companion to these books which illustrated the key features using field photos of live flies and close-up shots of specimens to make the identification process more accessible. The huge growth in records coming from photos posted online meant that we especially wanted to target photographers who wish to put a name to the animals in their pictures. Moreover, had we used traditional keys, the book would have been 400+ pages long and would have been considerably more expensive. Britain’s Hoverflies was quite a brave move for WILDGuides at the time because they had not tackled such a large insect family. The design and the contents had to be marketable, appealing and affordable to people who might not normally buy a book on flies. Coming up with guidance that does not involve keys has been a challenge and we must credit Rob Still for the design inspiration and turning our rough ideas into something workable. Since that first edition, the book has evolved and expanded. It is now a lot bigger, but we have held to our basic belief that it should be complimentary to these other works rather than a replacement.

This updated edition includes revised maps, flight-period charts and population trends for hoverfly species across Britain. Have you observed any changes in behaviour or distribution in response to developing environmental challenges? And do we have a clear idea of how these insects are likely to be impacted in the future?
All insects are responding to a plethora of environmental changes, but we are in a better position to investigate the challenges facing hoverflies because there is such a big dataset and new data arrives in volumes that we could only have dreamt of 30 years ago. Some species are expanding their range, while for others the frequency with which they are recorded is diminishing and/or their range is contracting. Species that were once at the edge of their European range have moved northwards, some quite dramatically. Several new species have arrived, apparently under their own steam, as their European ranges have expanded, but others have been assisted by lax biosecurity. A few species have disappeared from south-east England or are in the process of doing so.
It might be assumed that the twin evils of habitat loss and agricultural intensification (including pesticides) are primarily responsible for these changes; however, we think that climate change is having a far more profound impact than is currently accepted. Flies have very thin-skinned larvae and are highly susceptible to changes in humidity, so increases in the frequency and intensity of heatwaves and droughts will have a big impact on them. This sensitivity makes them important indicators – they are arguably climate change canaries that help to explain why so much of Britain’s precious biodiversity is disappearing. Flies are at the bottom of the food chain, so if you lose flies there will be fewer insectivorous birds and mammals, let alone predacious invertebrates such as wasps and spiders.
Hoverflies of Britain and Ireland is published by WILDGuides and is available to pre-order from our online bookstore.
