Author Interview: Andrew G. Duff, Beetles of Britain and Ireland Vol 3

In our latest Q&A we talk to Andrew Duff, keen naturalist and author of the new book Beetles of Britain and Ireland Volume 3, which joins a monumental 4-volume identification guide to to the adult Coleoptera of the Republic of Ireland, the United Kingdom of Great Britain & Northern Ireland, and the British Crown Dependency of the Isle of Man. By bringing together reliable modern keys and using the latest taxonomic arrangement and nomenclature, it is hoped that budding coleopterists will more quickly learn how to identify beetles and gain added confidence in their identifications.

Andrew has taken his time to answer our questions about his book and about the fascinating world of beetles.

 Aside from the most conspicuous species, beetles seldom seem to attract as much attention as some other insect orders. What is it that has drawn you to study this group? 

My initial attraction to beetles was by coming across some of the larger and more colourful species, as you might expect. The first occasion was in about the late 1970s. I was out birdwatching with my oldest and best friend, the Ruislip naturalist Mike Grigson, when he found a species of dor beetle. These are large black beetles, often found wandering in the open on heaths and moors. They have the most striking metallic blue undersides. Picking one up, Mike said to me: “beetles are really beautiful ”, and I can still picture him saying it. The next occasion was when I was assistant warden at the Asham Wood reserve on the Mendip Hills in Somerset, in the summer of 1982. The warden, Jim Kemp, was an expert mycologist with a side interest in beetles. One day we were on the reserve and he pointed out a black-and-yellow longhorn beetle sat on an umbel. I thought it was very exotic-looking, every bit as worthy of a naturalist’s attention as butterflies and orchids! So I resolved to find out more about the beetles found in Asham Wood. Bristol Reference Library had a copy of Norman Joy’s Practical Handbook of British Beetles and it was obvious that I needed to buy it. Once I had my own copy of ‘Joy’, there was no stopping me. I started finding beetles and was able to identify most of them. The more you study beetles, the more you realise that all of them have their own special kind of beauty, and this is what ultimately led me to become a coleopterist. That, and the intellectual challenge of identifying small brown beetles, are what continue to inspire me. 

 What motivated you to write and publish Beetles of Britain and Ireland?

Joy’s Practical Handbook of British Beetles was the standard beetle identification guide for at least two generations of British coleopterists, ever since its publication in 1932. Joy’s book provided concise keys to every British beetle in a handy two-volume set, one volume of text and one of line drawings. The trouble with this idea is that the keys were oversimplified and misleading because of all the detail that wasn’t included. By the 1980s ‘Joy’ was already long past its ‘best before date’. Talk started about somebody producing a successor set of volumes and the late Peter Skidmore made a start—after his death I was fortunate to obtain his draft keys and drawings, and in particular have made much use of his drawings in my book. Peter Hodge and Richard Jones then published New British Beetles: species not in Joy’s practical handbook (BENHS, 1995). This was a fantastic achievement because it brought together in one place a list of the species not included in ‘Joy’, as well as notice of recent changes in nomenclature and of some errors in his keys. But it was still only a stop-gap measure.

By around 2008 still nothing had been produced by anyone else. I reckoned it might be achievable and began to discuss with other coleopterists the idea of writing a new series of volumes. The turning point was a discussion with Mark Telfer at a BENHS Annual Exhibition in London. My main concern was over the use of previously published drawings in scientific papers, but Mark reassured me that provided the drawings were properly credited and that the book was clearly an original work in its text and design then it should not fall foul of any copyright issues. By 2010 I’d already made a start on Beetles of Britain and Ireland and in the summer of that year took early retirement so that I could work on it more or less full time. My own professional background is as a technical author in the world of IT and from the 1980s onwards I’d had extensive experience of what used to be grandly called desktop publishing, what we would now call simply word processing! I’d decided to go down the self-publishing route so that I could ensure the production values matched what I thought coleopterists would want: a book which was laid out clearly and would stand up to a lot of wear. It’s really for others to judge whether my volumes meet the needs and expectations of most coleopterists, but so far I’ve been pleasantly surprised at how well they’ve been received.

 How did production of this book compare to the previous volumes in the series? Was it difficult to bring together information on so many families exhibiting such a diversity of life histories?

As this is the third volume to have been completed I’d already learnt a lot about the best way to collate all of the material and summarise it, while trying to make as few mistakes as possible. The previous two volumes (vols. 1 and 4) were written in a rather erratic fashion, so that at any one time some sections would be more or less complete while others would not even have been started. This time I was determined to be more disciplined by starting with the first family, completing a draft which included the family introduction, keys to genera and species, and all of the line art illustrations, before going on the next family and doing the same again. In a way, having many families was an advantage because it meant I could use a ‘divide-and-rule’ strategy by breaking down a fauna of 1088 species into 69 smaller chunks. The fact that there are so many families in this volume didn’t generate any special problems, indeed families with only a few species like the stag beetles, glow-worms and net-winged beetles are relatively straightforward to document. But some of the family introductions were a challenge, insofar as some families are poorly defined taxonomically and hard to characterise in a way which would be accessible to amateur coleopterists. For example the darkling beetles (Tenebrionidae) exhibit a bewildering diversity which makes it well nigh impossible to say why a particular species is or is not assigned to this family. I made extensive use of the two-volume American Beetles (Arnett et al., 2002), which contains succinct summaries of nearly all of our beetle families, and this made my job a lot easier. But at the end of the day, the family diagnoses are not as important as the keys to genera and species. Most coleopterists won’t be coming to a particular family chapter as a result of methodically working through the key to families in volume 1. I imagine that in most cases people start by comparing their beetle with the colour plates, getting a shrewd idea as to what family it belongs to, and then going straight to the keys to genera and species. Picture-matching will always have its place in natural history, and I hope that Udo Schmidt’s 473 colour photos in this volume will be put to good use.

 This volume covers some of our most familiar beetles – the ladybirds and chafers, for example. What advice would you give to anyone seeking to extend their interest beyond these well-known families to the more ‘obscure’ groups? 

I would say that it largely depends on what kind of naturalist you are. What I mean by this is that there are two main ways of studying beetles, and you have to decide which path is right for you. On the one hand, many naturalists take photographs of beetles and by using the Internet or an expert validation service such as iRecord (www.brc.ac.uk/irecord/) they can usually achieve reliable identifications, at least to genus level, for medium-sized and large beetles. Some spectacular finds of beetles new to Britain have been found by general naturalists posting their images on the Internet, a very recent example being the flower-visiting chafer Valgus hemipterus, first posted to iRecord in April 2019 and already given the full works treatment in my volume 3. The problems start as soon as you try to identify smaller and more obscure beetles, because most of them are simply not identifiable from photographs. It’s not their small size and lack of bright colour patterns as such, so much as the need to view the underside, or the fore legs from a particular angle, or the head from the front, or the body orthogonally from directly above to ascertain the precise shape, which makes field photography impractical as a way to identify small beetles. So what you need to do is to go down the second path and start a beetle collection. This enables you to examine your specimen with a bright light source under a good stereomicroscope, turn it over to examine the underside, stretch out its legs to look for the pattern of teeth and spines, straighten it to measure its length and width, and if you’re feeling brave dissect out the genitalia which often provide the only definitive way to arrive at a species identification. Many naturalists balk at the thought of collecting beetles, but I would argue that the scientific value of having a comprehensive species list for a site outweighs any squeamishness I might feel about taking an insect’s life. In any case, my guilt is assuaged by the fact that insects are being eaten in their trillions every day, everywhere, by all manner of insectivorous animals and plants, so that the additional negative effect of my collection on beetle populations is vanishingly small.

Could you tell us a little about the process of compiling keys for the identification of the more challenging species? Were you able to draw upon the existing literature, or did you have to create them from scratch?

Some of the genera treated in this volume have been giving problems for coleopterists ever since the scientific study of beetles began. These are genera with a number of very similar, small and plain species that appear to have few distinguishing features. Nine genera in particular stand out for me as being conventionally ‘difficult’: Contacyphon, Dryops, Cryptophagus, Atomaria, Epuraea, Carpophilus, Meligethes, Corticaria and Mordellistena. It was always going to be a challenge for me to provide workable keys to these ‘nightmare nine’ genera, but I was keen to give it a go. It helps that I take a perverse interest in very difficult identification challenges, so I was motivated to come up with keys which would work. Fortunately I was able to pull together information from a variety of different sources until I had draft keys which could be put out for testing. The testing went through a number of iterations and by reworking the keys—for example adding my own illustrations, simplfying or reorganising couplets, or adding new couplets to account for ambiguous characters—they were gradually improved until I was happy with them. A second source of difficulty concerned the aphodiine group of dung beetles. The formerly very specious genus Aphodius was recently broken up into 27 smaller genera, and our leading dung beetle expert, Darren Mann, recommended to me that we should adopt the new taxonomy. This meant that I needed to construct a completely new key to genera, and that took a great deal of time and effort searching for characters. Incidentally I’d like to pay special thanks to Steve Lane and Mark Telfer for their advice and help with these difficult genera; I owe them both a great deal for their encouragement and support. The keys to challenging genera in this volume will certainly not be the last word on the subject, but I believe they are an improvement on previous keys.

 When gathering information on habitat and biology of the various families, did you notice any glaring omissions? Are there any families that could particularly benefit from further study?

Some of the families treated in this volume are well understood, in terms of their identification, ecology and distribution in Britain and Ireland. The scarab beetle family-group, jewel beetles, click beetle family-group, glow-worms, soldier beetles, ladybirds, oil beetles and cardinal beetles are all popular groups and have been reasonably well studied, while the ladybirds have received a huge amount of attention! But that accounts for just 13 of the 69 families treated in volume 3, and the remaining 56 families are in general much less well known. Modern identification keys in English already existed for some of the other families but for most the information is very basic. I would say that the biggest gap in our understanding concerns the synanthropic and stored-product beetles. Not only do amateur coleopterists rarely come across these species, but the information that has been gathered (mostly by food hygiene inspectors) has not been made publicly available. In a few cases it’s not even clear which country a species has been found in, and all we know is that it has been found at some time, somewhere in Britain. I would like to think that this group will one day be much better documented.

A particular favourite of mine are the silken fungus beetles (Cryptophagidae). This family contains two of the ‘nightmare nine’ genera: Cryptophagus with 35 species and Atomaria with 44 species. I’ve tried hard to produce workable new keys for these two genera, but their identification is never going to be easy and it will be necessary to validate records for a long time to come. But I hope that at least this family will begin to benefit from a greater level of interest, on the back of my new keys.

 There will be one more volume to come before this monumental series is complete – are you able to provide an estimation as to when that will come to fruition?

Volume 2 covers just one huge family: the rove beetles (Staphylinidae). This has been left until last for two good reasons. Firstly, the subfamily Aleocharinae, and in particular the hundreds of species in the tribe Athetini, are so poorly understood that it’s just not clear where the generic limits are drawn. This means I will have my work cut out trying to construct a new key to Aleocharinae genera. Preferably the key won’t involve dissecting out the mouthparts and examining them under a compound microscope, as we are expected to do now! Secondly, it has to be admitted that rove beetles are not the most exciting to look at. As publisher as well as lead author of my series of volumes it was always going to be difficult to sell a book which didn’t contain a lot of colourful plates. My plan all along, then, was to leave the rove beetles until last, in the hope that people would buy the book in order to complete their set! Volume 2 has already been started, and Udo has been working hard on the colour plates, but there is still a mountain to climb to complete the Athetini keys and illustrations to my satisfaction. My best estimate currently is that it will be published no later than 2024. Once that is done, and if I still have my wits about me, I suppose I’ll have to think about revised editions of the earlier volumes!

British wildlife in lockdown

Long-tailed Tit was a new species for Michael Scott’s garden, in north-west Scotland. Michael Scott

This is an extended version of an article, ‘British wildlife in lockdown’, that appears in the June issue of British Wildlife

Amid the enduring difficulties of the COVID-19 pandemic, it has been heartening to see the resourcefulness, resilience and imagination shown by the naturalist community. To give a taste of this, we asked our British Wildlife contributors how they had spent their time through late March and April, when restrictions were at their tightest. Here we give you the delightfully varied responses that came back. I hope that readers enjoy this snapshot of life in lockdown for the naturalist.

A spectacular spring

The start of lockdown coincided with a most exceptional run of fine spring weather (April was duly confirmed by the Met Office as the sunniest since 1921). While it was somewhat torturous to watch this unfold from the confines of our homes, time outdoors was all the more invigorating for it and the usual spring arrivals and emergences were met with even greater joy than normal.

A number of our regulars have tracked the changes as spring progressed, and Simon Leach has been encouraging local recorders to do the same: ‘I’ve been recording first flowerings since 2008 in the Taunton area, replicating (sort of) a similar exercise undertaken by Walter Watson in the first half of the twentieth century. And this year, constrained by “lockdown”, it seemed like a good idea to “widen the net” to get others in Somerset recording first flowering dates as well.’ By late May more than 35 participants had been drawn to the cause, and their recording from the height of lockdown through to the time of writing, in late May, has highlighted an extraordinarily early spring: Common Dog-violet Viola riviniana, Greater Butterfly-orchid Platanthera chlorantha and Biting Stonecrop Sedum acre, for example, have all had their earliest first flowering dates since Simon started the initiative.

Spring seemed to arrive early farther north, too, as Michael Scott notes: ‘Lockdown in the northwest Highlands is not too different from normal life here, but with few tourists and without the incessant afternoon hum from the rush hours of transatlantic jets. April 17th was a red-letter day. As I ate breakfast, I spotted the first Swallow of the year. Going outside, I heard the first Cuckoo from the adjacent hill. Later, a distinctive off-key scolding from the coastal bay below the house told us that the Common Sandpipers were back, too. They were respectively one, four and two days earlier than we recorded last year, but I suspect that may just reflect more observer effort!’

And it was not just summer migrants and wildflowers that were making early appearances, but also spring invertebrates. David Christie, copy checker for BW, noted the following from his home in Southampton: ‘Among the highlights were the garden’s earliest ever Dark-edged Bee-fly, on 16th March, a pleasant sunny day which also produced a Comma, a Small Tortoiseshell and two Brimstones. On 26th, an astonishing addition was a single male Wood White, unsurprisingly the first ever for the garden — but some 6 weeks too early! I imagine that this, the daintiest of the whites, was bred and released by somebody nearby (several people have released butterflies in the area in previous years). In April Orange-tips became the commonest butterfly, and on 16th of that month a Red-tailed Bumblebee, supposedly a common species but a garden first, turned up; it stayed for several days but had apparently disappeared by the middle of the following week.’

Peter Marren has enjoyed tracking changes on his local patch in Ramsbury, Wiltshire: ‘The sunniest side of this enforced lockdown is that I have come to appreciate home turf as never before. It helps that this has been the brightest, if not the warmest, April for some time, but this year the beauty of the meadows, woods and downs around Ramsbury has made me gasp, as if seeing it for the first time. I watched while a late spring turned into an early one. Frog spawn, flocculent and chilly, appeared in the ditch outside during the first week in March, and by the second week in April the tadpoles were already well grown. I heard the first Chiffchaff, much later than usual, on March 18th. It was joined in song by a Blackcap by March 25th. I heard the first Willow Warbler on April 5th (they are still doing well here, and have spread from the valley scrub into a belt of trees below the down, planted 15 years ago). The first Orange-tip fluttered into my garden on 9th April. The first singing Reed Warbler began –like a cold engine warming up – on the 10th, I spotted the first Swallow on the 13th and heard a solitary Cuckoo calling from the reedbed on Easter Sunday, 12th April. There was a close tie-in this year with the opening of our two cuckoo flowers, Lady’s Smock Cardamine pratensis and Lords-and-Ladies Arum maculatum. I should perhaps mention that spring usually comes late to Ramsbury. We are in a narrow east-west valley where a cold westerly blows from the Marlborough Downs and puts everything back by about a week.

‘Apart from the perennially exciting arrival of our summer visitors, I find I am looking at the small, easily overlooked things in life. This year I watched the leaves unfurl. Ash has, for once, tied with oak (so perhaps we are in for neither a splash nor a soak). Its feathery leaves push upwards in a shuttlecock from a bush of spent flowers, then angle out stiffly on their long petioles. By contrast, the leaves of oak curl softly from their buds, masked by a screen of yellow-green catkins. For a day or two, the hedgerow oaks take on an almost autumnal hue before they turn spring-green, that delicate, tender green that lifts the heart and makes you feel young again (anyone know any good oak songs?). Baby oak leaves lack the bitter tannins that build up later on. I nibble some straight from the branch – green chewing gum. Isolation makes you do strange things.

‘I’m also looking at bees. The only way I can get close to a bee is with close-up binoculars. Where banks face the sun, and especially when they are sheltered by a hedge, the mining bees are busy, locating their little, barely visible excavations, and vanishing into them bearing heavy loads of bright yellow pollen. Much of it, I note, is taken from Leylandii cones (so let’s hear it for once for that much-maligned conifer). Watching the bees at work are a whole host of parasites. On 31st March there was a brief flurry of oil beetles. Later on, nomad bees and blood bees were swarming about, each intent on laying a single egg inside the mining bee’s chamber. Patrolling bee-flies will do the same. The proper bees do not seem to notice that they are surrounded by malevolent cuckoos. Imagine a troop of hostile visitors raiding your cupboards and your fridge, sleeping in your bed, chasing away the kids. And that’s before the insecticides get you. I am glad I am not a bee. I am glad I live in Ramsbury. The swamp may be muddy yet – for the valley has taken a long time to recover from February’s floods – but it is full of life. Nature is the perfect antidote to despair in this surreal, locked-down spring.’

A number of correspondents noted what an excellent spring it has been for invertebrates, and bees in particular seem to have been popular with those wishing to use their time in lockdown to get to grips with a new group. From Anglesey, James Robertson writes: ‘I sit on a low wall, dangling my legs. After a while a queen Garden Bumblebee heads into a gap at the base of the wall by my feet. I am learning the skill my ornithologist brother tried to teach me many years ago. Then I was having none of it. Plants sat around on their bottoms, I had to search them out, keep on the move. But this year everything is different. Be still and the insects come to you. As so often, the constraints we are under force us to be creative, to learn new tricks and look at the world afresh.

‘As the dominant hominid falls silent, nature booms and buzzes. The exceptional weather puts on a display of insect variety. Wasp Beetles bounce around my garden, flicking their antennae and not looking quite right for the wasps they pretend to be. Red Mason Bees investigate holes in concrete posts and Joanna’s Bee Hotel, a future bee smorgasbord for hungry Blue Tits. She has quickly mastered the identification of Early, Garden, Red-tailed and Buff-tailed Bumblebees.

‘My car windscreen is splattered with insect bodies. This is supposed to be a memory, how it was when we were children. Is this explosion of life a sign of what would happen if we stilled the great machine of our industrious world?’

It was not the abundance of bees but a single unexpected one that provided a highlight for our copy editor, David Hawkins: ‘I was delighted when a rather smart solitary bee appeared in my flat in Bristol, having blundered in through the window. I consulted Falk & Lewington at length, but was perplexed – trying my damnedest to make it an Andrena of some sort, although none of the candidates looked quite right. Plus it had very beautiful mottled dark blue-grey eyes. Then, using a hand lens, I caught sight of a small spike on the underside of the first sternite – this, apparently, is diagnostic of a male Spined Mason Bee Osmia spinulosa. It seemed very curious to encounter it in the middle of the city, but we live near a railway line and some allotments so there may well be suitable habitats there. Most interestingly, as with some other Osmia spp., it nests inside vacant snail shells.’

While lockdown may have produced a new generation of bee enthusiasts, it was perhaps not such a good time to pick up an interest in flies. Alan Stubbs reports that his garden ‘is almost bereft of hoverflies; yesterday I achieved the fourth species for the March–April period and I have never seen more than two of any on a lap of the garden. Flies as a whole are very sparse even now (23rd April), a shame in the lockdown. The current drought does not help, but there is a legacy effect from low populations and drought last year. The excessive winter rains have not been of benefit (and have possibly been a negative factor). Currently it is difficult to know how widespread the doldrums extend, but I suspect areas that have had more rain over the last four to six weeks will have fared a bit better. Reports from London and Warwickshire suggest I am not alone.’

Bringing wildlife to you

While opportunities to go out into the wider countryside were limited, many found ways to bring wildlife to their doorsteps instead. Moth-trapping has seen a surge in popularity, as Paul Waring explains: ‘Moth-trap operators are better placed than many wildlife enthusiasts to cope with lockdown arrangements. Most of us routinely operate a light-trap in our gardens, and some do so on verandas and roof-tops if they have no garden. With a light-trap the moths come to us, from the garden itself, and from beyond it, so we do not need to leave our home to record what is about. The numbers and variety of moths in the catch and the seasonal patterns of occurrence always hold some interest, even in inner city locations. One is sometimes amazed at what turns up. Facebook has been full of people reporting their garden catches, often including photos of the moths, sometimes with lively discussion, throughout the lockdown period.’

The staff at Butterfly Conservation, unable to get out into the field, have also focused on moths in their gardens. Mark Parsons tells of some early highlights: ‘During lockdown the conservation staff at Butterfly Conservation were encouraged to run a moth trap at their homes. At least 28 staff participated, with traps being run from Devon to Cambridgeshire and north to Deeside, as well as in Northern Ireland. Although there were a few cool evenings in the first three weeks, generally conditions were relatively mild and very suitable, and as a result there were a lot of interesting observations. Of the scarcer species there were records of Silver Cloud Egira conspicillaris (Worcestershire), Small Eggar Eriogaster lanestris (Dorset), Marbled Pug Eupithecia irriguata (Devon) and the micro-moth Mompha divisella (Dorset and Glamorgan), with a Light Orange Underwing Boudinotiana notha (Surrey) being seen by day. Other interesting records included high counts of Lunar Marbled Brown Drymonia ruficornis (56) and Frosted Green Polyploca ridens (31), both on 11th April in Surrey. It really is amazing what can be found in gardens!’

BW’s Founding Editor, Andrew Branson, has been making good use of other technologies to monitor goings-on in his garden: ‘So often when we are observing the natural world we are looking at it from a very narrow perspective both in time and in space. We return to our favourite haunts looking for confirmation of the same species – the anxious scanning for returning migrants is a classic expression of this. I am always struck by the way we have a mental search pattern that reinforces what we expect to see. A classic is the way botanists with their stooping gaze on the ground will often fail to record unusual tree species right above them. In lockdown I have been trying to extend my appreciation of garden species by using a webcam to record nocturnal life. I’m lucky enough to have a garden that reaches down to a river, and have been discovering that not only do we have the expected Brown Rats, Mallards and Moorhens making regular nightly visits, but our garden also seems to be on the rounds of an Otter, an American Mink (not so welcome), Hedgehogs (first I’ve seen in the garden for years), Roe Deer, Foxes and Rabbits. Recently, the webcam captured a furtive pair of Tawny Owls having a midnight bath in the river!’

Dave Wilkinson has spent time studying some of the more obscure lifeforms in his pond: ‘Lockdown natural history: in the imagination it is snow leopards and camels as I read George Schaller’s new book Into wild Mongolia, while in reality it’s restricted to the garden and occasional short walks. In February we had a new garden pond dug, with the first water plants going in just before lockdown. With few ponds nearby it quickly attracted birds, hedgehogs and wasps; to drink, wash, or forage along the edge. Water beetles, pond skaters and water boatmen quickly followed. New ponds tend to be prone to algal blooms and ours is no exception. The torrential rains of February washed surrounding soil into the newly dug pond, adding nutrients, then the warm sunny weather of April powered algal photosynthesis – the pond first scummed with ‘blanket weed’, then turned bright green with cyanobacteria and other algae. Without lab access (no plankton net or centrifuge) some ingenuity allowed me to concentrate some plankton to view with a rather basic 50-year-old microscope. With such equipment colonial cyanobacteria – such as Aphanocaspa – were easier to isolate than smaller cells. The floating ‘blanket weed’ quickly vanished, but small patches of filamentous algae are in the shallows, including the green alga Stigeoclanium. Under the microscope these threads have the look of cells-within-cells, with small round green structures within the longer tubular cells. These structures are chloroplasts, the site of photosynthesis with the product stored as starch, staining dark when I added iodine. Back in the depths of geological time these chloroplasts evolved from free-living cyanobacteria; down my microscope I am seeing the history of our emerald planet encapsulated in the green scum of a garden pond.’

And in the terrestrial realm, Roy Watling has also been looking at some smaller organisms in his garden in Edinburgh: ‘Some years previously, when I was recovering from a medical procedure, I had to make time for exercise. I walked around the streets close to my house, gradually increasing the distance each day; I could not resist the temptation to “mycologise” though and began to list all the micro-fungi found on the vascular plant cultivars I saw in each garden. Now I am confined to my own garden because of lockdown I decided to conduct a similar survey, with surprising (to me at least) results. Thus, the tips of shoots of Irish Tutsan Hypericum pseudohenryi hosted the mildew Erysiphe hyperici, which is not uncommon on our native plants, while hidden among the erect branches of the snowberry Symphoriocarps x doorenbosii was another mildew, E. symphoricarpi. These two species are not rare but are poorly recorded in Scotland, and certainly neither has previously been recorded here on these hosts. The true mould Ampelomyces quisqualis, a parasite of a range of mildews, is equally under-recorded, although can be obvious to the keen observer. Also evident in my border was blotching on the shrub Hebe x francisciana: a rather distressing sight caused by the fungus Septoria exotica. On the north facing side of the house where it is moist and shaded, Chaetothyrium babingtonii grows prolifically in a mixed planting of various Rhododendron cultivars and hybrids. This fungus is common and widespread under the right conditions, and although it does not appear to harm the plants it looks very unsightly – thank heavens it only occurs on Rhododendron!’

Frances Dipper has been observing the interactions between some more familiar species: ‘The human brain is much better than a computer algorithm at picking out patterns (hence ‘Galaxy Zoo’ – the web-based project that uses citizen scientists to classify distant galaxies based on their shape) so changing from recording fish (and other marine life) to birds and garden wildlife is proving to be a fascinating experience during lockdown. Seashore recording and diving are time-limited, but looking out at a habitat resource (i.e. the bird feeders in my large, wildlife-friendly garden) is not. As a marine biologist learning to be an ornithologist, here are some recent observations. Some Greenfinch Carduelis chloris prefer to spray out sunflower hearts from the feeder and then eat at their leisure on the ground below – memories of rich arable field pickings? Much smaller Goldfinch Carduelis carduelis will hold their ground (perch) on the feeder in the face of Greenfinch bully tactics. Starling Sturnus vulgaris are now adept at clinging on to feeders – perhaps our Cambridge ones are fast learners. Great Tit Parus major will nest in vertical holes, in this case a hollow brick column. There is also a Magpie Pica pica nest in our oak tree. A faithful Spotted Flycatcher Muscicapa striata pair used to nest every year in the same vine until a Magpie raided its nest a few years ago. The best sighting to date? Not a bird but a Grass Snake Natrix natrix swimming across the pond and obviously unaware that Great Crested Newt Triturus cristatus is a protected species! Now how did one of the latter get into my downstairs shower room?’

And the extra time at home allowed Michael Scott the chance to notice garden visitors who might have gone undetected in a normal year: ‘Freedom from urgent deadlines has meant more time to observe how regularly a pair of Yellowhammers come to join the Dunnocks and an occasional fat Bank Vole feeding on the grain that ungrateful Chaffinches and House Sparrows regularly scatter onto the ground from our bird feeders. A small group of Long-tailed Tits in early April was a first for the garden. One was collecting the frayed ends of some garden string, presumably for a nest somewhere in the area.’

David Christie noted some apparent effects of the lockdown itself on the birds in his garden: ‘Perhaps the most notable feature of April–May was that many birds were becoming unusually tame. When I was “tidying” a corner of the garden, an adult female Blackbird walked around my feet, picking up odd items of food; feeding within a few centimetres of my feet, she occasionally looked up at me to check what I was doing! The visiting Stock Doves, too, were tamer than usual. On 24th April, a pair of Blackcaps had begun nest-building just a metre from our back window; although several Blackcaps regularly spend January–April in the area, they have never before nested here (sadly, the pair deserted at the laying stage). By the end of the month, a Blackbird pair with three fledglings showed no fear of humans, nor did a fully independent young Robin.’

And Hugh Raven similarly has been musing on the possible effects of lockdown on the wildlife of his local loch and beyond: ‘Float over the deep belly of our local sealoch and look north, and you spy two rivers as they reach the sea – in plan like the outstretched arms of a mermaid’s purse. Embraced by these limbs is a verdant turf of saltmarsh fringed by a pancake of sandy mud, twice daily exposed when the tide recedes. At this time of year, it’s the haunt of sawbills. Goosanders and mergansers are by nature shy and flighty, but this year they are abundant. With human traffic around the loch and up these rivers – never heavy – a fraction of the norm, having eaten their fill they laze about on foreshore and saltmarsh preening in the spring sunshine. I counted 18 one day in late April. Sawbills are good at fishing. Research from Norway reports “adult goosander on average eat from 310 to 500g fish a day”. At this time of year they’re enjoying the feeding opportunities presented by the smolt run – that evolutionary miracle that sees juvenile salmon pour downstream as maturity, light and temperature tell them to reset their osmotic meter, leave fresh water and start to fatten up in their marine phase.

‘Salmon smolts weigh some 20g, so if they are the main source of food, each duck may eat twenty or more a day. Thousands will disappear down their gullets. The local river is noted for the freshwater pearl mussel – which depends on migratory salmonids to survive. You can get a licence to shoot sawbills, but there’s no appetite for that here. Salmon and pearl mussels, or these beautiful sleek and shiny ducks? Such are the dilemmas of conservation.’

Natural history online

The lockdown experience would surely have been very different had it happened in the not-so-distant past. Social media, and the online world in general, has changed our hobby and helped naturalists to stay connected throughout this period (see Brett Westwood’s column in this issue for more on this topic). Members of the birding community, for example, have been enjoying the rapid sharing of news, and a healthy element of competition, while working on their ‘lockdown lists’.

White-tailed Eagles have provided some excitement during lockdown; many sightings across England involved juveniles from the Isle of Wight reintroduction project, but the pictured individual, seen in Buckinghamshire, was unringed. Dan Forder

Dawn Balmer reports: ‘The movements of the released White-tailed Eagles from the Isle of Wight have been well tracked by the birdwatchers fortunate enough to spot them flying over their gardens (see https://bit.ly/2X5YXlK). I’ve also been amazed how many people have recorded Osprey over their garden, too! Both species seemed to have avoided airspace over our garden, though we were lucky enough to see two Cranes circling overhead on 20th May.

‘The first few nights of April saw a large passage of Common Scoters overland. While not a new phenomenon, it has never been documented so well. Birders stood in gardens and listened in the dark, others set recorders to record overnight – see https://bit.ly/3e5ejhj for a summary. Personally, we sat outside in our garden in Thetford (Norfolk) on the nights of 1st and 2nd April and heard Teal and Wigeon on the 1st, and Wigeon again on the 2nd. We’ve since added Moorhen to our house list – heard one fly over calling at 3.45am, and Dunlin, which flew over calling at 10.30pm one evening! With a bit more time on people’s hands, more have taken up “nocturnal migration” recording.’

Adrian Knowles has been monitoring the Facebook pages of the Essex Field Club, which has produced some notable records through lockdown: ‘Rob Smith posted a picture of the fly Bibio venosus from his daily walk patch, Headley Common in south Essex. Apparently there are only two other records in Essex, both in the north of the county. He has also recorded the mining bee Andrena cineraria from the same site – this species remains a scarce in Essex. There were two records of the ladybird Rhyzobius forestieri, a recent colonist of the UK, including one in someone’s garden. Then, on 10th April, Ed Hardy grabbed a load of wood chip during his morning walk with a view to identifying contents during his lockdown time. His finds included the beetle Rugilus angustatus, which is rare in the county, with a lack of recent records.’

Martin Harvey, David Roy and Helen Roy offer some insight into the effect of lockdown on submissions to iRecord, the online biological recording system maintained by the Biological Records Centre (part of the UK Centre for Ecology & Hydrology): ‘April 2020 proved to be a busy month with over 100,000 records added, up from about 75,000 in April 2019. It’s hard to know how much of this increase is the result of people taking up wildlife recording as an activity while locked down close to home, and how much is due to the combination of overall growth in records arriving at iRecord and the sunny weather that many experienced during April. But there do seem to be some changes in the patterns within these records. Not all biological records state the habitat that they were recorded in, but for those that do there has been a clear shift, with the proportion of records assigned to gardens more or less doubling, and a big fall in the number of records assigned to “wilder” habitats such as woodlands and grasslands. The most frequently recorded species during the month have been typical garden visitors, including butterflies such as Orange-tip and Peacock, the Dark-edged Bee-fly, Hebrew Character moth and Buff-tailed Bumblebee.’

‘Records arriving in iRecord are checked and verified by expert naturalists on behalf of the national recording schemes. An impressive three-fold increase in verification during April 2020 compared to the previous year is testament to the dedication of these people, and no doubt also demonstrates they have been making good use of the time that might have been spent in the field during a different year.

‘What effect these changes will have on the total pool of records available for 2020 remains to be seen, but it will be exciting to consider the ways in which these records can contribute to the long-term analyses that BRC and the recording schemes collaborate on. In the meantime, we hope that as many people as possible have been able to find ways of connecting with nature during these unprecedented circumstances.’

Butterfly Conservation has encouraged people to track species undergoing range expansions; during lockdown, a Comma was reported at Dunnet Head – its most northerly ever location in Britain. Edith Jones

The lockdown has provided an excellent opportunity to fill in gaps in distribution maps and monitor species on the move by encouraging the submission of records. Butterfly Conservation, for example, is asking the public to report on butterflies seen in their gardens, as Caroline Bulman explains: ‘Understanding the changes in patterns of emergence and distribution across the UK is vital to improving our understanding of the impacts of climate change on butterflies and other native wildlife. Wherever you live your observations are even more vital this year and particularly those in northern England and in Scotland, where you can record novel information of species which are spreading northwards, in response to a changing climate. For example, in mid-April we had a report of the most northerly Comma ever recorded in Britain, found in Caithness on the north coast of Scotland! If you’d like to get involved go to https://bit.ly/3bM1gQk to register and download a free smartphone app, or sign up to record butterflies in your garden, on your PC or laptop at https://bit.ly/2WOQ40M where you can also read the results from 2019.’

Paul Waring used the daily exercise walks to further the understanding of moth populations in his local area: ‘During lockdown we have taken the opportunity of beating for caterpillars to start recording the colonisation by moths of a hedgerow of various native broadleaf trees newly planted to screen from view a field of solar panels. We have also carried our pheromone lure for Emperor moths Saturnia pavonia with us every day to see if the large “white hole” for this species shown just south of The Wash in the newly published Atlas of Britain and Ireland’s Larger Moths reflects lack of recording or a genuine absence. Thus far it appears the Emperor really is absent, although this is certainly not the case for many other moth species for which there is a similar white hole.’

For some groups, recording need not be limited to our time outside the house either. Geoff Oxford writes: ‘The British Arachnological Society, working with Jordan Cuff (Cardiff University), has launched two “lockdown” spider surveys that can be completed around the house and garden. One is to record the species, numbers and locations of the three British cellar spiders –the very common Daddy-long-legs Spider Pholcus phalangioides, the much less common Wine Cellar Spider Psilochorus simoni and the rare Marbled Cellar Spider Holocnemus pluchei. The second, newly launched, is to record when clusters of Garden Spider Araneus diadematus spiderlings are first noticed. Details of both surveys can be found on Twitter @BASSurveys and at britishspiders.org.uk. Response so far to the first survey has been good with some 50 people counting a total of over 185 cellar spiders, some in previously unrecorded hectads.

‘The lockdown has not seen arachnologists locking away their equipment. Initiated by Richard Wilson and Chris Cathrine, naturalists nationwide have taken to surveying their garden lawns in a two-minute sample using modified garden blow-vacs. Early results include a new spider for Yorkshire, Cryptachaea blattea. The survey has led to informed discussion via Twitter @britishspiders and #lockdownsuckschallenge, creating a forum for promoting more widely spider biodiversity in gardens. Lockdown has seen an unprecedented surge in interest in arachnids more generally; we have been inundated on Twitter.’

Examination of old material produced a record of Caloplaca aractina (the grey lichen) from Muck, in the Inner Hebrides – a remarkable range extension for a species previously thought to be restricted to The Lizard, in Cornwall. John Douglass

Lichenologists, too, have been getting better acquainted with their home patches, with some excellent results – Sandy Coppins reports: ‘Lichens lend themselves to “local looking” perhaps more than several other wildlife groups. BLS Twitter suggested recording lichens on your doorstep, window sill or garden, etc. But after your initial ten lichens seen on your patio slabs, where to go next? Heather Paul, in Forres, says “I amused my neighbour by going down on my knees on the pavement outside to look at Lecanora muralis which of course I have never recorded here.” While in North Wales, Dave Lamacraft on a gentle potter to look at some nearby trees, “with a view to better learning some common things in ‘normal habitats’ for a change”, was surprised to find Ramalina lacera almost straight away swiftly followed by Schismatomma graphidioides – both pretty rare in Wales!

‘But perhaps the most surprisingly fruitful and fascinating lichen results from the lockdown came from not stepping out the door: John Douglass, in South Lanarkshire, for example, writes “I was sorting through some old boxes of specimens… and came across some C[aloplaca] aractina collected from a coastal rock face on Muck (2012). I have checked it against my collections from the Lizard and the spores etc. check out good for this species.” Apart from John’s Muck revelation, C. aractina is confined in the British Isles to coastal rocks at The Lizard, in Cornwall, so this find is a lovely disjunct extension.’

To conclude

As for the BW editorial team, while we have each been left slightly envious of those people with gardens we made the most of our daily exercise walks.

Female Hairy-footed Flower Bee. Catherine Mitson

Catherine Mitson, BW‘s Assistant Editor, reports: ‘Except in times of flooding, the Exwick spillway is a popular route for runners and cyclists alike. To one side, however, is a less frequently visited footpath that follows the natural flow of the River Exe. Here, the shrubs and trees grow a little more wild, and the tall bank to the right muffles the sound of passers-by. I can now enjoy the soundtrack of my walk, featuring the nasal ‘dzwee’ of Greenfinches, the chattering of Blackcaps, melodic Song Thrushes, and the drumming of a Great Spotted Woodpecker. This was the first time I had been here, despite living so close – a direct consequence of the lockdown. I now visit this small stretch almost every day and have seen the unmistakable flash of a Kingfisher, a Dipper on two occasions, and, looking up, there are often noisy Long-tailed Tits hopping around in the branches. During the last week of April, House and Sand Martins have arrived and are now regularly seen zipping across the river as the evening sets in. The first few sunny weeks of lockdown stirred many insects; of the butterflies I have spotted so far my personal favourites include Orange-tip, Common Blue, Peacock, Comma and Brimstone. My first Dark-edged Bee-fly of the year is always a personal highlight, but this was topped as I happened across a Hairy-footed Flower Bee nesting site in a cob wall less than five minutes from my house. These strange times have certainly opened my eyes to what lies just beyond my doorstep.’

For myself (Guy Freeman), the lockdown highlights have come from strolls along my local beach here in Teignmouth which, naturally, have been timed to coincide with the best tides. The shore – mostly expanses of brick-red sand – does not look the most inspiring from a rock-pooling perspective, but I always enjoy the challenge of searching for life in these damp deserts. The walks during lockdown have been among the most productive I have had here, with favourite finds including some of the more weird and wonderful sand-dwelling specialists – the Angular Crab, which looks too exotic for these shores, and the more common but equally bizarre Masked Crab.

Many thanks to all the contributors to this piece who responded so enthusiastically to our initial call for submissions.

Celebrating 30 years of British Wildlife!

With the publication of the October issue of British Wildlife, the magazine has reached 30 years in print. British Wildlife found its home here at NHBS in February 2016, but it owes its existence to founders Andrew and Anne Branson, who first brought it to press back in 1989. In our 30th anniversary issue, we were delighted to learn more from Andrew about the earliest days of the magazine.

Andrew Branson, founder of British Wildlife magazine

A shortened version of Andrew’s piece, ‘British Wildlife – how it all began’, is included below. To find out how to read the full article, see here.

Taking ‘the path less travelled’ has often been a failing of mine. In early 1988, after another week of commuting up to London as a publisher for a large multinational publishing house, I came to the conclusion that there must be a more enjoyable way to earn a living. Perhaps not such an unusual thought, but what surprised colleagues were that I then effectively headed off into the ‘undergrowth’ of rural Hampshire to set up British Wildlife Publishing, with the support of my wife, Anne. My work had allowed me to spend days in the field with some great naturalists, and through discussions with those it became obvious to me that there was a need for something different that captured the expertise of some of our best field naturalists, provided up-to-date information on the rapidly changing world of conservation and, importantly, was also a first-class read. 

First published in 1989, the covers have remained largely unchanged

In the 1980s it was still the case that, by and large, people were much more blinkered in their interests. For example, birdwatchers seldom took note of other groups of animals and plants and the entomologists were generally a small, tight-knit group of specialists. I was looking for something that would break out from this bunker mentality and act as a showcase for the great work being done in British natural history.

There were, of course, numerous scattered membership magazines and journals for the various specialist societies, each promoting its own agenda, but how could you find out what was happening with wildlife around the country? Sometimes the journals reported on events years after they had happened. And remember, this was before the days of emails and social media. Communication was all about telephone calls and letters; networking was down to attending conferences and field meetings. In the end, I worked from the premise that, if it excited me and I would buy it, then others, too, would do the same.

I was also increasingly aware of the work of the Nature Conservancy Council (NCC), not only in advising the government on contentious issues but also in producing detailed research documents. At an early stage in planning the magazine, therefore, I visited this important hub of expertise in Peterborough. A good working relationship with this team was critical and I received a warm welcome from Philip Oswald, the communications boss, who introduced me to several people who became key contributors.

Bringing all this together in 1988, I decided to create a completely new magazine that would cover all aspects of wildlife and nature conservation in Great Britain and Ireland, and that, despite its broad geographical remit, it would be called ‘British Wildlife’. The watchwords of the publication were to be accuracy, independence of view and quality. The proposed contents were to include a mix of articles and news which deliberately juxtaposed information on subjects as diverse as bryophytes and birds, flies and flowers, conservation news and reserve management. Planning the potential contents was relatively straightforward, but coming up with a team of people that would put it together was another thing.

The first issues

The first issue of British Wildlife went to print in October 1989

The first issue of British Wildlife came out, after a long hot summer (one computer caught fire!), in October 1989. We printed 5,000 copies and initially sold just under 2,000, but within a few years, they had almost all been sold. In addition to the various in-depth articles, the first issue included the wildlife reports, pretty much as they are today, with, extraordinarily, still some of the same contributors: here we find the butterfly news written by Nick Bowles, moths by Paul Waring and flies by Alan Stubbs. Peter Marren, then working for the NCC as a writer, and his inimitable column ‘Twitcher in the swamp’, appeared in the fourth issue and there he has remained, with the odd holiday, right up to today. After struggling at first to find a hero to take on the herculean task of sifting through newspaper cuttings and press releases to produce ‘Conservation news’, Sue Everett came to the rescue in 1991 and has ever since been ably riding the waves of news, including, more recently, the tsunami of information that now floods the internet.

Herein lies one of British Wildlife’s great strengths: a reliable team of highly knowledgeable and talented contributors that have been with the magazine, through thick and thin, for decades. I take my hat off to them all.

Some great names and articles

Happily, many people understood what British Wildlife was trying to achieve, and we soon had articles from some of the seminal voices of the time. Derek Ratcliffe first wrote for the magazine in its second issue. This was a stinging rebuke to the government concerning the breaking-up of the NCC (BW 1: 89–91) – I can still remember the fire in his eyes as he described what was going on. Later he authored two masterful articles on ‘Upland birds and their conservation’ (BW 2: 1–12) and on the ‘Mountain flora of Britain and Ireland’ (BW 3: 10–21). Chris Mead, of the British Trust for Ornithology, was a great voice for birds and conservation, and enthusiastically backed British Wildlife from the start, contributing the birds report until his untimely death in 2003. Another important commentator on conservation was Colin Tubbs of NCC/English Nature. He took a much wider view on matters than most, and several of his contributions in the 1990s introduced a more international flavour to the magazine.

The familiar white cover first appeared in 1992, at the start of volume 4, and has remained more or less unchanged ever since.

Often, important topics were being raised in British Wildlife years, if not decades, before they became part of the general discourse of the national media. A good example of this is a superb article by Alan Rayner published in 1993 on the ‘Fundamental importance of fungi in woodlands’ (BW 4: 205–215), in which Alan explains the intricate nature of the relationship between such things as mycorrhizal fungi and woodland health. We published an article on ‘Climate change and British Wildlife’ back in 1994 (BW 5: 169–179). An early article that caused much controversy was one on woodland management, ‘Biodiversity conservation in Britain: science replacing tradition’, by Clive Hambler and Martin Speight (BW 6: 137–147). British Wildlife has always been open to occasionally ‘stirring the pot’, but this piece boiled over into a debate that reached the national newspapers. It precipitated several excellent articles in response, including from Martin Warren, who had regularly written on the conservation of butterflies from the first volume. Also gathering impetus in the early 1990s was the idea of creating ‘wilderness areas’, as opposed to using more traditional farming practices. Contributions from Tony Whitbread and Bill Jenman (‘A natural method of conserving biodiversity in Britain’, BW 7: 84–93) and a reply from Colin Tubbs (BW 7: 290–296) are an example of an early skirmish from almost a quarter of a century ago.

It was pleasing to introduce Robert Burton, with his regular column, ‘Through a naturalist’s eyes’, in 1995. Each of his columns is a wonderfully crafted piece of natural history observation. Bill Sutherland, now Miriam Rothschild Professor of Conservation Biology at the University of Cambridge, first started the ‘Habitat management news’ section back in 1992 and his renowned evidence-based approach to wildlife management was clear even then. Some of the identification articles have been illustrated by Richard Lewington’s wonderfully accurate artworks and, indeed, were occasionally a testbed for some of the field guides that we were later to publish.
