Author Interview: Peter Eeles, Life cycles of British & Irish Butterflies

NHBS recently attended Butterfly Conservation’s 2019 AGM in Shrewsbury. The event was highly enjoyable, with many excellent speakers, and we were excited to unveil the brand new NHBS Moth Trap at our stall; lookout for a blog post on this new product shortly.

During the day we also caught up with Peter Eeles, creator of the UK Butterflies website and author of the ground-breaking Life Cycles of British & Irish Butterflies to talk about his fascination with Lepidoptera and the process of writing this incredible book. Peter was also kind enough to sign a number of copies of his book which are now available to purchase here.

1) Could you tell us something about your background and how you first became interested in butterflies?

I grew up on the southern side of Cheltenham, on the edge of the Cotswolds, an area rich in butterflies and other wildlife. It was all rather idyllic and I remember with some fondness the time spent out in the countryside with my fellow explorers! My father and my ‘uncle Fred’ encouraged this interest, but it was watching a Garden Tiger moth emerge from its chrysalis, and seeing scores of Red Admiral feeding on rotting plums, that tipped me over the edge and into a butterfly-filled life.

2) How long did it take you to put Life Cycles of British & Irish Butterflies together?

Two years to write, 20 years to obtain the photos needed, and a lifetime of study! I should say that the book would not have seen the light of day were it not for the contributions of many others, especially members of UK Butterflies (a website that I set up in 2002), the team at Butterfly Conservation, and various experts in their chosen field, such as David Simcox, project manager of the Large Blue reintroduction programme.

3) In your introduction to the book, you detail its aims in relation to Frohawk’s landmark text, Natural History of British Butterflies. You say that Frohawk is one of your heroes: was his work the driving force for you wanting to take on your own project?

I wouldn’t say it was the driving force, but it was certainly a huge inspiration in terms of understanding the ‘art of the possible’, and the amount of field observation and research that would be needed. The driving force was a desire to produce something different yet useful, especially a work that would contribute, in some small way, to the conservation of our butterfly fauna. Something ‘clicked’ when I read several research papers that relied on the identification of a particular larval instar (the period between moults), and I realised that anything that could help the army of butterfly recorders identify each instar and the immature stages more generally would be a great help, with the potential to open up a whole new dimension of butterfly recording.

4) What was the most challenging butterfly lifecycle to document?

That’s a harder question to answer than you might think! Chequered Skipper was challenging due to the amount of travel involved, although a work placement in Glasgow for two years, on and off, really helped! Mountain Ringlet was a challenge due to the remoteness of its sites, its short flight period and its tendency to disappear deep into grass tussocks in anything other than very bright conditions. The Large Blue, which spends most of its life in an ant nest, was always going to be a challenge, and my thanks go to David Simcox, Jeremy Thomas and Sarah Meredith for their help with this tricky subject.

5) There is evidence that butterflies are already being influenced by climate change – what worries you the most about this? Are there any species that you will be excited about seeing more frequently in the UK in the future?

My biggest concern is with less mobile species that are unable to move to suitable patches in our increasingly fragmented landscape, as their habitat becomes unsuitable, or is lost due to development or agriculture. Conversely, it would be nice to see semi-regular visitors, such as the Long-tailed Blue and continental Swallowtail, gain a foothold, just as the Red Admiral and Clouded Yellow can now be considered resident, with records of successful overwintering each year in southern England.

6) Have you any new book projects in mind for the future?

No plans as yet, but never say never!

British Dragonfly Week – Author Interview with Dave Smallshire

In order to celebrate Dragonfly Week (13^th – 21^st July 2019), we interviewed Dave Smallshire, the renowned dragonfly expert and co-author of the excellent Britain’s Dragonflies field guide. Dragonflies and damselflies form the order Odonata and are some of our most iconic insects, with a fascinating life cycle. Damselflies are weaker fliers than dragonflies and have four almost equal length wings that they usually fold up when at rest.

Dragonflies have shorter hind wings and tend to keep their wings out when at rest. Primarily associated with glittering, iridescent glimpses at ponds and wetlands, dragonflies actually spend the vast majority of their lifetime (up to five years) as nymphs in rivers and other water bodies. Both the adult and nymph forms are ferocious predators. Adults are able to move each of their four wings independently and have exceptional vision, giving an astonishing aerial ability that allows them to select a single insect from a swarm. Meanwhile the nymphs are able to jet propel water behind them and use their extendable hinged jaw (labium) to capture prey at lightning speed.

Dragonfly week is organised by the British Dragonfly Society and offers a range of activities designed to celebrate these amazing insects, including the Dragonfly Challenge where you can search for six species and submit your records to the BDS.

Interview with Dave Smallshire by Nigel Jones

1. Could you tell us a little about your background and how you got interested in dragonflies?

As a child I have fond memories of playing around water: dipping into ponds and canals and later fishing (without much success). As a teenager, birds became a passion (they still are), but other things with wings began to attract my attention, notably butterflies and dragonflies. Working in an agricultural entomology department in the 1970s, I was conscious that insect identification keys were useless in the field and it wasn’t until half-decent field guides appeared that I really got to grips with dragonflies and had seen most species by the mid-80s. Soon after, my colleague Andy Swash and I started leading a long series of weekend courses for the Field Studies Council in Surrey/Sussex. When Andy and Rob Still began producing the first of the WILDGuides ‘Britain’s Wildlife’ series, it was a natural progression for us to start work on a field guide to dragonflies.

2. Can you give a brief insight into the time and work that goes into producing a field guide such as Britain’s Dragonflies?

First and foremost, writing and producing such a complex book as Britain’s Dragonflies takes twice as long as you think it will! In addition to drafting all the text, we had to source all the images, which for the first edition (2004) meant viewing hundreds of slides and scanning the best. For subsequent editions, it’s been equally laborious to search the internet and choose the most suitable from many thousands of digital images. Then we had to get permissions and high-resolution files from the photographers. I spent many days with Andy editing the text so that it is absolutely clear and concise – not an easy task! On the publication side, Rob Still was guided through his production of both the illustrations and the amazing photomontages. It’s been hard work, but a real honour to be able to be involved in producing one of the best series of field guides available anywhere.

3. Dragonflies are iconic and familiar insects; how are they faring in terms of population numbers and distribution in the UK?

Until recently, we only had occasional atlas maps to show changes in range, but the British Dragonfly Society, in conjunction with the Biological Records Centre, has worked on a method to use ad hoc records from observers to produce national trends using occupancy modelling. We knew that climate change was aiding northerly spread of some species within Britain and colonisation attempts by species from continental Europe (which makes for exciting times to be out watching dragonflies), but we had little objective information on how our ‘resident’ species were faring. The latest analyses support the obvious increases in species such as Migrant Hawker and colonisers such as Small Red-eyed Damselfly, but also much less obvious decreases in ‘northern’ species such as Black Darter. There seem to be more winners than losers, but next year will see a full analysis for a State of Dragonflies 2020. The generally improved water quality and increase in the extent of wetland creation has no doubt helped many species – a general picture which is in stark contrast to the fortunes of other insects, and wildlife in general.

4. What actions could people take, either within their gardens, or in the wider community to help maintain or increase dragonfly numbers?

In gardens, the obvious answer is to dig a pond – I have two in mine, and they are a constant source of pleasure! Supporting the creation and ongoing management of wetlands in general is also important, so supporting local and national conservation bodies is a good thing. It’s also very important to gather records of dragonflies and help to monitor them, and everyone can help by submitting their sightings (the BDS website gives information on how to do this, as well as how to create a pond for dragonflies).

5. What was your most surprising discovery whilst researching Britain’s Dragonflies?

I have been astonished at how many images on the internet and in social media are misidentified. Even the experts get it wrong sometimes! Take care not to believe everything, and of course buy a good identification guide to help ….

6. What is the biggest challenge when studying dragonflies in the field?

That’s hard to pin down, because I’m aware of so many potential pitfalls! Correct identification is fundamental. Finding out where to see the scarce species to expand your skills is hard, but easier with modern communications. Dragonflies are wary and not easy to approach, so close-focus binoculars and/or a camera are vital – the advent of good quality digital cameras has been a huge benefit. I’ve used a sequence of zoomable Lumix ‘bridge’ cameras over the last 10-15 years to help study wildlife of all kinds, both in the field and back at home. The British weather can be challenging too: a warm, sunny day makes all the difference!

7. Have you got any future projects planned that you can tell us about?

Andy and I have been working for about five years on Europe’s Dragonflies – which is now close to completion and is due for publication next spring. Like all the WILDGuides books, it’s based around high-quality images – in this case over 1,100 of them! It will be presented in a similar way to Britain’s Dragonflies but cover an extra 77 species.

Author interview – Dave Goulson

Dave Goulson is a Professor of Biology at the University of Sussex and nature writer, with a particular passion for bees. Bee Quest and A Buzz in the Meadow were bestsellers, and his latest book, The Garden Jungle is all about the wildlife that lives with us: in our gardens and parks, between the gaps in the pavement, and in the soil beneath our feet – an insight into the the wildlife that lives right under our noses.

Dave visited NHBS to meet the team and sign a few copies (now sold out) of The Garden Jungle. He also answered a few questions about the inspiration behind his new book and his hopes and ambitions for the gardens of Britain.

How did your interest in the natural world begin?

I’ve no idea! I have been somewhat obsessed by wildlife, particularly by insects, for as long as I can remember. When I was only five or six years old I remember collecting cinnabar caterpillars from the weeds on the edge of my school playground and rearing them up on my bedroom windowsill in jam jars. I never grew out of my interest, and have been lucky enough to find a way to make a living out of it.

2. Could you tell us a little about the research that went into writing The Garden Jungle?

I’ve been both gardening and studying insects for all of my adult life. The two go hand in hand, for if you grow the right plants, and garden in the right way, you can attract all sorts of insects to your garden. I’ve often done my scientific experiments from home, for example studying bee behaviour and the flowers that they choose. I also try out many of the techniques that are said to help wildlife for myself; my garden is full of more than twenty homemade bee hotels, two ponds, nine compost heaps, four or five log piles, a wildflower meadow area, half a dozen ‘hoverfly lagoons’ and more.

3. What fauna and flora gives you the most pleasure to see in your garden?

It is hard to beat the excitement of seeing the first brimstone butterfly of the year, a flash of bright yellow usually seen on the first warm day in late February or March, a sure sign that spring is coming. But bees are my real obsession, particularly bumblebees, colourful, furry, and endearingly clumsy insects that bring the flower borders to life with their buzzing activity.

4. Are you a keen gardener yourself?

I love gardening. When I’m not at work or asleep, I am somewhere in my two acre garden in the Sussex Weald, growing veg, fruit and flowers, and looking after the birds and the bees. It is my own little piece of heaven.

5. Have there been any changes over the past fifty years – either for the benefit or to the detriment of wildlife in the way people view their gardens?

There has certainly been a great increase in interest in encouraging wildlife into our gardens, for example via bird feeders, tit boxes, bee hotels and by planting bee-friendly flowers. Many of us believe that gardens can be places where people and nature live in harmony. On the other hand there have been many detrimental changes too; Astroturf lawns, decking, hard paving, and a huge increase in the number of chemicals available for use. Gardening has become big business; nowadays many people’s idea of gardening is to drive to some vast garden centre and fill the back of their car with annual bedding plants grown in peat-based composts, drenched in pesticides and sold in disposable plastic pots. There is nothing green about that approach to gardening.

6. If someone wanted to link gardens together for the benefit of wildlife, what would be your advice to enlist the neighbourhood’s cooperation?

Often the best way to convince people to change is to show them the alternative. If your garden is wildlife-friendly, invite your neighbours round for a coffee and show them the butterflies nectaring on flowers, the bees busy stocking their bee hotel, and the flowers in your not-too-tightly-mowed lawn. Offer them some seeds or cuttings of bee-friendly flowers; I give comfrey roots to anyone willing to grow them, it is one of the very best plants for bumblebees and I’m trying to encourage everyone to have a clump of it somewhere.

7. Do you have any new projects in the pipeline that you’d like to tell us about?

With colleagues at Sussex University I recently launched the Buzz Club, a nationwide organisation which is working with the public to do experiments to test interventions for garden wildlife. For example, we are asking people to test out creating a ‘hoverfly lagoon’, miniature ponds intended to provide homes for the offspring of some types of hoverfly.

Invertebrate Survey: Moth Trapping

Many of us delight at butterflies visiting the flowers in our gardens, be it the drunken admirals of autumn or the spritely orange-tips in spring, yet some of us still seem to shudder at the thought of dingy moths bothering our windows at night or worse still munching our clothes to dust in our cupboards. In the middle of June, armed with two moth traps and a couple of trusted field guides, I attended an open garden in Somerset ready to join the #Mothsmatter conversation initiated by Butterfly Conservation to dispel the moth myths and encourage a fascination for these insects.

All the essentials for cataloguing a moth catch!

Setting up a Skinner moth trap in a covered porch over a couple of cold nights, I wasn’t entirely sure what species would be flying, but sure enough in the morning as I lifted the lid and slid the egg boxes out, there were some delightful species to see. Visitors in the garden were suffice to say, in awe of the moths the light brought in; the Poplar Hawk-moth and the Eyed Hawk- moth, the Fox Moth with his rabbit ear antennae and the remarkable Buff-tip.

We are becoming well aware that UK moths are in decline with an overall decrease in numbers by 28% since 1968, and over 60 species becoming extinct in the 20^th century. Moths are a key indicator of environmental health and, as vital as they are to other creatures as a food source (their declines are impacting on breeding birds and bats) they are also vital for the pollination of native flora, an essential element to the tapestry of wild life. There is also evidence to suggest that climate change is shifting the habitable ranges of many of the moths that call the UK home, and while this can produce some spectacular species visiting from continental Europe, many of the species that have relied on the temperate climate in the UK are being forced out northward.

With a recent trend in wildlife gardening and more strict rules on chemicals used in agriculture, there is hope however that we can retain and rebuild some of the moth populations that are so vital in our countryside. Butterfly Conservation have a wealth of information available on their website about the trends of moth populations and, very importantly, what you can do to take action, join the conversation and promote moths at https://butterfly-conservation.org/moths/why-moths-matter

If you are interested in learning about which moth species are visiting your garden or local wild places, light trapping is simple and loads of fun. At NHBS we supply a range of moth traps suited for a number of habitats and a wide selection of amazing field guides to aid in identifying the moths you find. Below we have listed some of our favourite traps and provided a little more information on the differences between them, however if you wish to see our full selection of moth traps please visit our website.

Robinson Moth Traps

These large traps are renowned among lepidopterists because they offer the highest attraction and retention rates available. These traps are fitted with either mercury vapour or actinic electrics. Mercury vapour bulbs offer greater brightness than actinic bulbs and consequently they will often attract more moths. However actinic electrics may be favourable in areas where the brighter bulbs may cause disturbance; they also run cold and do not need to be shielded from rain, unlike mercury bulbs which are likely to shatter when used without a rain guard.

Skinner Moth Traps

These traps are precursors to the Robinson, and as well as being a more economic choice, they allow the catch to be accessed while the trap is running. They feature a plastic or wooden box with a light fitted to a cross member above a long slit through which moths fall and become trapped. A highlight of this box are the transparent panels that make up the trap lid. These can be removed to access the catch while the trap is running, which is great for real-time surveys and demonstrations. These traps can be easily collapsed down for easy storage and transport.

* Price: £179.00 inc VAT
* Dimensions: 32 (h) x 35 (w) x 35 (d) cm
* Weight: 3kg
* Electrics: 240V mains electric

Heath Moth Traps

These traps are favoured for their lower cost and compact design which makes them highly portable (excellent for use in remote areas) and easy to store; some are even small enough to fit into a rucksack. They are usually battery powered and feature a low wattage light source of between 6 and 20 Watts (however some mains operated traps can reach 40 Watts), and consequently these traps have lower catch sizes and retention rates than Skinner or Robinson models.

Solitary Bee Week

Although we are all familiar with the important role that bumblebees and honeybees play in pollination, over 90% of the UK’s 267 bee species are in fact solitary bees. Pollinating animals are responsible for one third of the food we consume and solitary bees are particularly efficient pollinators. Unlike other bees solitary bees do not have pollen baskets and so transfer much more pollen between flowers, meaning a single red mason bee provides a pollination service equivalent to 120 worker honey bees. This makes them a critical resource in our gardens and wider countryside and one that we should all be keen to protect. We have collated some information below on how to help encourage and preserve these fascinating creatures.

Solitary Bee Ecology

Solitary bees use a wide range of nest sites including tunnels in wood or mortar, plant stems and even snail shells. They lay eggs in a series of cells and then block the entrance with materials such as mud, leaves or fine hair. The female lays an egg with a food source, made from pollen and nectar, before building a partition wall and moving on to the next cell. The bee larvae hatch, eat the food source then overwinter as a cocoon before emerging the following summer as adults.

Solitary Bee cells in the Solitary Beehive

There have been extremely worrying declines in insect numbers recorded across Europe, and solitary bees are no exception. The increased use of chemicals in farming, loss of flower meadow food sources and loss of nest sites in hedgerows and gardens are all combining to drive down numbers. The good news is that it is easy to provide food sources and nesting habitat in your garden to help solitary bees and increase pollination.

Providing Resources for Solitary Bees

Provide food sources for solitary bees by planting wild flower seeds, native trees such as hawthorn and willow, bee friendly plants such as ivy, foxgloves and lavender and allowing plants such as borage and thistles to flower in your garden. Nest sites can be provided by leaving dead wood and stems standing, creating a patch of bare earth or mud bank for mining bees and by installing wild bee houses.

With careful design consideration, bee houses can provide shelter and nesting sites for solitary bees. Bee houses can be manufactured from a variety of materials but should have a good overhanging roof to protect the nesting tubes from rain, nesting holes between 2 and 10mm in diameter and a solid back. It is better to have a number of smaller bee houses, rather than one large house to reduce the risk of parasites finding the nest. Alternatively we have a wide range of solitary bee nesting habitats available on our website.

You can tell which species of bee is using your bee house by examining the material used to plug the entrance hole. Different species also emerge at different points in the year. The most common species likely to populate bee houses are red mason bees who use mud and are active March – July, leafcutter bees who use leaves and are active May – September, and wool carder bees who use fine hairs and are active June – August. Please note that there are fewer solitary bee species in the North of England and Scotland.

Solitary Bee House Siting and Maintenance

Insect houses should be sited at least 1m off the ground, facing south or south-east, with no vegetation covering the entrance and in full sun as insects need warmth to keep moving. They should be firmly fixed so that they don’t move in the wind. If your box is likely to be occupied by red mason bees then it is helpful to ensure that there is a patch of damp mud nearby. In order to maximise the chances of adults emerging successfully from the cocoons, it is a good idea to bring bee boxes indoors into an unheated shed or garage during the winter to avoid them getting too damp. The boxes should then be taken back outside in March in time for the new adults to emerge. There is some debate as to whether brick / concrete boxes should be cleaned but they can be cleaned out with a tent peg and pipe cleaner. Boxes with cardboard tubes should have the tubes replaced regularly. Keep an eye out for failed nests and tiny holes in the mud entrance as this can indicate that the nest tube has been taken over by parasites.

Author interview: Peter Marren

Written with Peter Marren’s usual wit and insight, Emperors, Admirals & Chimney Sweepers takes you on a journey back to a time before the arts and science were divided. When entomologists were also poets and painters, and when a gift for vivid language went hand-in-hand with a deep pre-Darwinian fascination for the emerging natural world.

Peter took the time to answer some of our questions about his new book and the origin of butterfly and moth names.

Tell us a little about your background and how you got interested in the etymology of species names?

I’m a natural history writer (in the sense that I’ve written a lot about natural history) with a background in nature conservation in Britain. I’ve loved butterflies and moths since boyhood, and I suppose I must have realised even then that many of them have unusual names. What the hell was an eggar? Or a lutestring? Probably like most people I didn’t think too much about it – weren’t names just labels? – until, out of curiosity, I went into the name of the Red Admiral, Vanessa atalanta, and discovered a real Vanessa and a real Atalanta. And then I realised that even Latin names weren’t randomly chosen but had a particular resonance with that particular species. Names hid a whole new world of allusion, poetry and wordplay. I discovered that those who named our Lepidoptera, in English and Latin, were equally educated in the arts and the sciences. They knew their myths, and they knew about colours and designs, and they were completely fascinated. I feel a strange empathy with that vanished world.

What was the original inspiration behind Emperors, Admirals & Chimney Sweepers?

It started as a kind of sequel to my book Rainbow Dust, about how and why butterflies and moths inspire people. Names were confined to a single chapter in that book, but there was so much more to say, not only about the names themselves but the social ambience that spawned them: the world of Georgian London with its clubs and field excursions, its gorgeous illustrated books and the sense that nature was all the more wonderful for being 1) divinely inspired and 2) almost completely unknown.

The lightbulb moment came when I thought of dealing with names not as an entomologist might do, by families and related groups, but by themes: species named after animals, birds, moods, occupations, jewels and so on, all laid out alphabetically. I loved the fact that certain fine moths were named after weddings, focussing on bridal underwear worn in eighteenth century Sweden!

Emperor, Admiral and Chimney Sweeper are, of course, names of a butterfly and two moths.

If you could name a new species of moth or butterfly, how would you go about it?

Well, it ain’t a blank slate. There are written rules for scientific names and unwritten ones for common names. I’d love to call it Marren’s Glory but it would not be approved. I’d have to stick with the established vocabulary. So if it resembled, say, a wainscot moth, it would continue to be called that, distinguished by whatever word best caught its character. Overlooked Wainscot? Lenitive Wainscot? Look-alike Wainscot?

What would be your advice for any budding entomologist out there?

There’s more to the natural world than pure science. Keep your eyes, and your mind, open. And enjoy yourself. And don’t say, “Oh that’s a Lenitive Wainscot, a Schedule 7 species graded as Least Concern in the latest IUCN Red List.” Just the name will do.

What is your most memorable butterfly or moth name, and why?

There are lots, but let’s go with the poor little Narrow-bordered Bee Hawk-moth, whose Latin name, tityus, commemorates the most hideous giant in all mythology. The giant’s poor mum exploded at his birth and when full grown his body covered nine acres. What do they have in common? Well, the old name for hawk-moths was Sphinx, and the Sphinx was a monster. Ergo (Linnaeus thought), hawk-moths should be given monstrous names. And the bee hawk accidentally got the worst of them because of its place on the list, wedged between two other appalling creatures.

I quite like Zygaena, the name of the burnet moths which they share with the hammerhead shark. For reasons too convoluted to go into here (but it’s in the book).

Any new books/projects in the pipeline?

I will have to find another project for it’s in the DNA. I suspect it will involve nature and childhood. Trouble is, others are on to it.

Field Guide to the Ladybirds of Britain and Ireland:

To the general naturalist, ladybirds are arguably the most familiar group of beetles and an up-to-date field guide has been long overdue. Now, after exhaustive research and diligent illustrations, this brand new field guide covering all 47 species of ladybird occurring in Britain and Ireland is finally available.

The authors Helen E. Roy and Peter Brown and illustrator, Richard Lewington signing the hardback edition exclusively for NHBS. Available while stocks last…

They also found time to answer a few questions regarding the making of this definitive field guide to the ladybirds of Britain and Ireland.

With all the research, detailed illustrations, and accessible format design of this guide, how long has this project been in the making?

As the illustrations of the adults, larvae and pupae were all made from living specimens, collected in the wild, we needed at least two seasons to collect them all, and for Richard to illustrate them.

Ladybirds are a niche set of organisms which can be often overlooked, where did the inspiration to produce this field guide come from?

The brightly coloured ladybirds are an extremely popular group of insects but the small so-called inconspicuous ladybirds are under-recorded. Similarly, the larvae and pupae of ladybirds are less well known. We hope that this field guide, adding to the popular series of field guides published by Bloomsbury, will encourage recording of all ladybirds in all life stages. It is also a celebration of the amazing contributions to the UK Ladybird Survey from so many people.

Field guides can provide an essential tool to assist monitoring and conservation efforts of species. Could you explain why our ladybirds may need to be monitored?

Ladybirds, like all insects, respond to environmental change in different ways. Some species are expanding in range but many others are struggling. Understanding these patterns and trends is extremely important for informing conservation and decision-making. Many species of ladybird are beneficial, providing pest control of common garden and agricultural pests such as aphids and scale insects, and so it is important to consider the changing dynamics of these important species. How ladybirds are responding to climate change is another important aspect that the monitoring data will show.

Each illustration is so detailed, what is the process for reproducing a ladybird so accurately?

Detail and accuracy are the two most important considerations when producing illustrations for a field guide and working from actual specimens, rather than from photographs, is essential. Only then can measured drawings be made for correct anatomical details. Photos can be used as a supplement and museum specimens are also helpful if live material is unavailable.

With each book or field guide you hear of unexpected challenges. What was the biggest challenge in creating this field guide?

As the larval and pupal stages of ladybirds are quite short in duration, the main challenge for Richard was having to illustrate them as soon as he received them, often by post. The larvae also needed to be fed, at the same time ensuring the carnivorous species were kept apart, as many are cannibalistic. The inconspicuous species were the most challenging to illustrate as they are tiny, most around 2–4mm long, and covered in minute hairs, which often form diagnostically important patterns on their wing cases.
It has been such a pleasure to work together – we have all learnt from one another along the way. It has been inspiring to hear from Richard about the microscopic details of some of the little ladybirds that had previously gone unnoticed by us.

The NHBS Guide to Moth Traps

Flatpack Skinner Moth Trap with Electrics — The Flatpack Skinner Moth Trap is made from FSC timber and is easy to assemble.

In this brief guide, we will take a look at the main types and designs of moth traps. We will also address many of our most frequently asked questions, including why you will no longer find Mercury Vapour traps for sale at nhbs.com.

Skinner Moth Traps

Skinner Moth Traps will attract in excess of 500 moths on a very good night. The main advantages of Skinner Traps are price and portability, and they also let you access your catch whilst the trap is running. Skinner Traps collapse down quickly and easily when not in use, making them very easy to store and transport. They are available with actinic electrics and can be provided with either 240V (mains powered) or 12V (battery-powered) control panels. Lucent traps have a clever design with all components fitting neatly into a suitcase-style case.

Heath Moth Traps

The traditional Heath Moth Trap has a small actinic tube mounted vertically within three vanes that work together to attract and then deflect moths downwards into the holding chamber below. The traps are very lightweight and portable and are usually powered by a 12V battery, although mains powered traps are also available. Variations on the Heath Trap design include the “Plastic Bucket” model which allows the trap to be packed away and carried conveniently. Although catches from Heath Traps tend to be less than for Robinson and Skinner traps due to their lower wattage bulbs, their affordability and portability makes them a great choice for beginners or for use at remote sites.

Moth Collecting Tents

Moth Collecting Tents provide a unique alternative to traditional style moth traps and are ideal for educational use or group trapping events. They consist of a large white fabric structure that is fitted with a UV light source. Moths that are attracted by the light settle on the white fabric and can be observed or collected for study. As the collecting area is large and accessible, it is easy for many individuals to view the specimens at the same time. However, tents and sheets do not have the same retention rates as traditional box-type traps.

Moth Trapping FAQs

What kind of trap is best for garden or educational use?
The design of the Skinner Trap means that you can access the catch without having to switch off the bulb. This is particularly useful if you are looking at your catch over the course of the evening, rather than leaving the trap all night and returning to it in the morning. Skinner Traps also have the added benefit of collapsing down, making them easier to store.

Which trap is best for unattended trapping?
Some moths will escape from both Heath and Skinner trap designs, but Skinner Traps will attract a higher number of moths.

Which trap is most portable?
Heath Traps are the smallest and easiest to transport. They can also run off a 12V battery, allowing them to be used in remote sites. The Safari and Ranger Moth Traps are the smallest and lightest traps we sell, so are ideal for travelling.

Why can I no longer find Mercury Vapour traps on your website?
Mercury Vapour bulbs have recently been phased out as part of the Restriction of Hazardous Substances Directive. Therefore, we have removed the traps from our range and are now focusing on actinic replacements. If you have a Mercury Vapour trap and would like to convert it to run with actinic electrics, please get in touch with us to have a chat about this.

What are actinic bulbs?
Actinic bulbs produce a small amount of UV light alongside the visible light which makes them more “attractive” to moths. They are not as bright as Mercury Vapour bulbs but because they don’t get as hot they are much safer to use, particularly for public and attended trapping events. They are also much less of a disturbance to neighbours if you are using the trap in your garden.

What is the difference in catch rates between the different traps?
Skinner Trap will attract the highest number of moths. Heath Traps will retain fewer moths but will still attract the same range of species. You can therefore obtain similar results trapping for a longer period or over several nights in the same area.

Do different traps attract different species?
No, all traps using actinic electrics will attract the same range of species. However, species of macro-moth from different families have been shown to vary in the extent to which they are attracted to a light source. This means that care must be taken when estimating local abundance from the relative abundance of species in your trap as some species will be attracted from a wider area than others.

Naturalist, artist and author Steven Falk on his new field guide to bees

Naturalist and wildlife artist Steven Falk has had a diverse career with wildlife and conservation, including working as an entomologist with Nature Conservancy Council, and as natural history keeper for major museums. He is now Entomologist and Invertebrate Specialist at UK invertebrate conservation organisation Buglife. His new Field Guide to the Bees of Great Britain and Ireland will be published by British Wildlife Publishing next month.

Tell us about your role at Buglife.
At Buglife, I have quite a diverse role. I provide information and advice to colleagues, external enquirers and a plethora of external organisations. I’ve been particularly involved with overseeing the production of new red lists for assorted invertebrate groups, also providing feedback to the various national pollinator strategies, new agri-environment schemes, plus helping to develop projects for some of our most endangered invertebrate species. We also have a consultancy now, Buglife Services, which carries out and coordinates invertebrate surveys all over Britain. We’ve just done an exciting survey of the A30 and A38 in Devon and Cornwall. We need more understanding of road verge invertebrates, especially pollinators.

How did you come to write this landmark identification guide to all the bees of Britain and Ireland?
I was approached by Andrew Branson in 2012 and was initially quite reluctant, because you cannot use a traditional field guide approach for bees, as many cannot be identified to species level in the field (they require the taking of a specimen for critical examination under a microscope) and it is crucial that we keep the national dataset (run by BWARS) clean and reliable by being honest about where the limits of field identification lie. So I agreed to write it on the basis that it covered all 275 species, had reliable keys, and could appeal to both hardcore recorders and general naturalists. I knew this was feasible, because we had faced the same challenge with the seminal book British Hoverflies (Stubbs & Falk, 1983, 2002). So it is a field guide in the loose sense – it will help you to recognise much of what you see in the field, but also indicate at which point you need to take specimens and put them under a microscope. But you don’t need to collect bees or have a microscope to enjoy the book – we made sure of that.

There is growing concern about the conservation status of bees – how are our bees getting on, and how might the publication of this book help them?
Yes, we need to be concerned about bees. We have already lost 25 species and several more are teetering on the edge of extinction. Good bee habitat continues to be lost. Brownfield land came to the rescue last century, but most of that has now been developed or lost its flowery early successional stages, which is what so many bees need. The research being carried out on pesticides such as neonicotinioids is also pretty disturbing – check out the work by Prof. Dave Goulson at Sussex University. It seems to be affecting bee numbers in many parts of the country. The national pollinator strategies being published by UK member states are a call to arms – let’s get monitoring bees. But the emphasis is on developing citizen science to achieve some of this, because there is little funding. High quality amateur recording is part of this plan, and Britain’s strong tradition of this makes it a realistic proposition. But the last comprehensive coverage of British bees was Saunders, 1896, and it has been the lack of modern ID literature that has held bee recording back. Field Guide to the Bees of Great Britain and Ireland, and the supporting web feature (embedded in my Flickr site) will hopefully fix this!

Your career as a wildlife artist began early – you worked on the colour plates for Alan Stubb’s guide to British Hoverflies when you were just a teenager. How did this collaboration come about?
I pinned some bumblebees I had caught near my home in North London when I was 12. Half of them turned out to be bee-like hoverflies, and that started a fascination with hoverflies. The following summer holiday, I went out with a net almost every day, and seemed to find a new type of hoverfly daily. I was totally hooked on them, and I painted things that fascinated me, including those hoverflies. I exhibited some hoverfly artwork at the 1976 AES Exhibition in Hampstead, and met Alan Stubbs who told me he was writing a new guide to hoverflies. I said I wanted to do the artwork (I was only 14), and the rest is history. It took 3 years of evenings, and I think I was 17 when I finished it. I’m very proud of those plates, and you can see how my style develops (plate 8 was the first and plate 7 was the last – you can see a lampshade reflection in the early ones!).

Do we see any of your artwork in this book?
Sadly not, my eyesight is not great these days and I do very little drawing and painting now. But the British Wildlife Publishing ‘house artist’ is the great Richard Lewington, and he’s done a magnificent job. The bumblebee plates in particular, are just stunning, the best ever produced.

What sort of techniques do you use to produce your artwork – which is strikingly realistic and very detailed?
I painted birds a lot as a young child and was very aware of the bird artists of the time and their styles, people like Basil Ede, Charles Tunnicliffe and Robert Gillmor. I particularly liked the detail and photo-realism of Basil Ede’s work and became aware that he used gouache. So I started to use gouache and preferred it to watercolour. I’d often start with a black silhouette and build up the colour and texture on top of this, which is the opposite of watercolour painting. But others, like Denys Ovendon and Richard Lewington, show what can be done with watercolour, so it’s just a taste thing. For really intense or subtle colours, I’d need to use watercolours, because they produce a much larger colour pallete than gouache. Richard knows his watercolours – you need to if you want to tackle butterflies like blues, coppers and purple emperors. I’m possibly more proud of my black and white illustrations than my colour work. Here I was most influenced by the likes A. J. E. Terzi and Arthur Smith, house artists for the Natural History Museum. Their use of cross-hatching and stippling is so skillful, and I’ve tried to emulate this in my pen and ink artwork. Never use parallel lines in cross hatching!

Any future interesting projects coming up that you can tell us about – artistic, or conservation-based?
There are many more books I’d like to write, especially for wasps and assorted fly groups. It’s not just the subject, it’s the approach. I like getting into the mindset of the beginner and finding the right language and approach. We need to get more people recording invertebrates. I like the double-pronged approach of books plus web resources, and I have a popular and ever-expanding Flickr site that greatly facilitates the identification of many invertebrate groups. On the conservation front, I’m keen to continue promoting understanding of pollinators and to increase the effectiveness of agri-environment schemes. Invertebrate conservation is in my blood and I’ll be pursuing it to the very end in one form or another. I might even try illustrating again one day if I can find the right glasses!

Recording Orthoptera using a bat detector

The Great Green Bush Cricket is the largest of the UK Bush Crickets. This beautiful image of a female cricket was taken by Charlie Jackson, from Flickr Creative Commons (CC by 2.0).

The order Orthoptera consists of the grasshoppers and crickets. Although most suited to warmer climates where they are incredibly diverse, in Britain we have 27 native species, as well as a number of non-native, naturalised species. From a very young age we are aware of these beautiful creatures as the sounds they produce fill our countryside with noise.

The characteristic Orthoptera song or “stridulation” is produced either by rubbing the wings together (observed in most of the grasshoppers) or by rubbing a hind leg against a wing (a method used by most crickets). The sound produced is an important part of the courtship ritual and is also used for other types of communication. As the sound created by different species varies significantly, studying these calls is an excellent way of surveying Orthoptera, and is helpful for finding individuals which can then be identified visually.

Stridulation produces a sound which covers a variety of frequencies – the sound made by grasshoppers is usually audible, but many species of cricket produce a higher ultrasonic frequency which cannot be heard by most humans. The use of a bat detector to listen to these higher frequency songs is an excellent way to listen to those species that we would not ordinarily be able to hear, such as the Speckled Bush Cricket. It also allows us to increase the range at which we can hear the audible ones. Bat detectors are also of use to older surveyors, whose ability to hear higher frequencies has naturally declined.

A simple heterodyne detector is perfect for listening to grasshoppers and crickets – one such as the Magenta Bat 4 or the Batbox IIID is ideal as it allows you to tune it to a specific frequency (as opposed to some of the more “intelligent” detectors which will alter it for you). The detector should be set to a frequency of 35-40kHz then all you need to do is sweep it around in different directions until you pick up your subject. It is best to stand in one place while surveying as the noise produced by your footsteps and clothes moving will produce background ultrasound noise which can confuse what you are hearing. The best days for surveying are warm and sunny; crickets are generally crepuscular (active during twilight) whilst grasshoppers are usually active throughout the day.

Unlike bat detecting, where the peak frequency is a key diagnostic feature for determining species, this information is less important for Opthoptera. Of more importance is the pattern and type of sound produced. The Environmental Records Centre of Cornwall and Scilly has a great guide to identifying Orthoptera including a useful information sheet on the use of bat detectors. They also have a collection of sound files of grasshoppers and crickets that you can use to recognise the typical calls produced by many of the species found in Britain.

Why not take along a leaflet or book to aid your identification: The FSC guide to British Grasshoppers and Allied Insects is a handy fold out guide with a useful key. For those looking for a more in depth guide, try the Photographic Guide to the Grasshoppers and Crickets of Britain and Ireland or the Pocket Guide to the Grasshoppers, Crickets and Allied Insects of Britain and Ireland.
