Silent Earth by Goulson 2021


Silent Earth, Averting the Insect Apocalypse, by Dave Goulson, Published by Jonathan Cape, London in 2021. (imprint of Vintage which is part of Penguin Random House, London.) 328pp. Hardback £20. ISBN 978-1-787-33334-5  &  9 781787 333345  A review:

Hot on the heels of other books on the impending disaster to affect the wildlife world we live in, this is another that adds to the debate. It seems that lockdown has had a positive effect on the productivity of all authors. But this assessment of the decline of insects is from an academic for consumption by the general public. And he is good at it, converting scientific facts, arguments and counter-argument into some interesting discussion. The author is Prof.  Dave Goulson, lecturer at the University of Sussex, who, when he is not writing books, looks after freshers giving them a tour of the campus to assess their readiness to understand the living world, identifying the common birds and the bees (which they do very poorly). His lecturing circuit of about 40 lectures a year allow him to assess audiences, and he agrees that talking to primary school schoolchildren is more fulfilling as they pay attention and are enthralled, compared to secondary pupils. He sees a drift of grey hairs in some of the older audiences and they also are more keyed into what is happening. He says that about 90% of the population could not care less about the environment, and he is right, possibly higher. This is however a flaw in his halting the apocalypse. Will they all respond?

There are five sections of the book, Why Insects Matter, Insect Declines, Causes, Where are we headed? and What we can do? in all 21 chapters. Each chapter is quite short and succinct and reads without giving specific references (making the text a better read), but the references are at the back of the book under chapter headings if anyone wants to fact-check Goulson’s comments and threads.  The author draws on his own academic published work, and his travels around the world making observations.  Having just reviewed McGavin’s audio book on insects (All Creatures Small and Great), both authors have used the same published work, whether it is the German experience of declining insects or the Knepp experience of wilding, and drawing on the quoted works of Carson, EO Wilson, Fabre, Monbiot or Attenborough.  It is surprising how there is a relatively small body of work on declining species out there, that everyone quotes. The difference with this book and the others is that Goulson supports all his commentaries with graphs and scientific evidence – almost, but not quite, at the level of a textbook. Most pages are enlightening, and the book can be dipped into to get a different flavour. There are at least ten books I have around me here on the impending Armageddon and the story is the same, the relatively few references the same, Carson being the first key witness.

So where does Goulson really stand. He is an optimist. He says on the flyleaf ‘it is not too late for insect populations to recover’. Attenborough also says that on television. That does not fit comfortably with the 90% who do not care less. Even the sub-title is optimistic ‘averting the insect apocalypse’. Topically he has one chapter on life in the future after the apocalypse several decades on, and another chapter on how to get things right before the apocalypse, education, involvement at local level and getting involved in politics. Goulson also muses on Rumsfeld’s ‘knowns and unknowns’ and ‘unknown knowns’ in the biodiverse insect world. He also has a chapter on ‘Bauble Earth’ about light pollution and effects on wildlife, also very topical at the moment.

Goulson is a bee expert and he often refers to his other books (three out of five on bees and bumblebees) and one has the feeling that one should have read his The Garden Jungle before writing this review as he often refers to it.  His appraisal of the effects of neonics on bees is excellent. Curiously, various vignettes on the peculiarities of a handful of insects are placed at the end of the chapters, not related to the subject matter, but the tiniest peek into the world’s biodiversity that we might loose, such as the earwig with two penises if you have ever seen it in the first place.   With the insect world in Britain of 27K species these are not key to the message of the book, and therefore a distraction, perhaps an entrée into the bizarre world of biodiverse insects for a new book?

Insects by McGavin 2022

All Creatures Small and Great. How insects make the World.  An audiobook written and narrated by Dr George McGavin. MP3 (14 hours). Published by WFH Original (W.F. Howes), £16.99   ISBN: #9781004073344    Link on Audible:   A review:


For those who have not come across George McGavin on the radio or on the TV he is a passionate, if not unique spirit of ecology who now works in the media but was once a lecturer at Oxford. We learn a lot about the life of McGavin, an early interest in bugs in Edinburgh from the age of 12 through to his latest tribute to the parlous state of insects worldwide. In some ways I thought this was a promo for The Royal Entomological Society (RES) as it so insect-centric (which I applaud) and one of its nine guest contributors is the president of the RES, Prof. Helen Roy – a ladybird authority. But insects rule the world with their complete mastery of numbers and diversity and put other classes to shame in biodiversity. McGavin says confidently that they will be around on Earth well after our own demise. Therein is the issue that grips McGavin throughout this audiobook. The relentless decline in species, that McGavin reminds us several times that he has experienced in his lifetime. We all have.  You can feel that he feels wounded as an entomologist that his subjects are disappearing, even species that could be useful that will become extinct before they are discovered (a very familiar and true refrain) with steady on-going rainforest loss that no one seems to be able to stop. He does not refrain from speaking the truth, whether it is rainforest loss just to grow new crops (oil palms, soya), burning peat for shooting, cutting verges or ‘unnecessary street lights’.  One of his most animated interviews is with the inimitable fly-centric Dr Eric McAlister particularly on the fruit-fly – 60% of whose 15.000 decoded genes are found in humans (a common ancestry) which cause cancer, offering hope for remedies for various diseases. He calls the fruit-fly ‘arguably the most important insect in the world’ – vying with the house fly as the most dangerous.  Like many TV reporters he asks many questions such as why and how we got into this mess, where have all the insects gone, and so what if they go extinct? But he does give answers. He talks to Sir David Attenborough to see if he has any answers to which he is told that he receives 50-70 letters a day, mostly, now from concerned youngsters. Attenborough’s solution is to i) individually do not waste food, space, fuel, paper etc, ii) that those who have an elected voice should appreciate the international point of view of the worldwide dilemma and do something, and iii) that that there is a need to get politicians to set out remedial measures.  Maybe we have all got it wrong, McGavin invokes Genesis 9.7 ‘be fruitful and multiply’. Yes, says McGavin we have done that, and spoilt the world. We have become complacent and here McGavin says that we have all fallen into the ‘Shifting Benchmark Syndrome’ where the gradual decline of species (example Passenger Pigeon) is easily missed and extinction occurs. He laments his windscreens not being encrusted with a pâté of insects, something we have all noted, and now wonder where they all went.  40% of all insects are now threatened with extinction towards an Eco-Armageddon. There have been mass extinctions before, 250yrs ago at the end of the Permian ‘The Great Dying’ but that was because of acidification of the oceans and gross volcanic activity. Insects at that time did not become widely extinct. Now we are told we are ‘in the middle of a mass extinction event’ the Anthropocene, during this The Age of the Human.  With difficulty we must triage what to save, which insect species we need to save.  We are told by Prof. Philip Stevenson (Kew Gardens) that two out of five plants are now currently at risk of extinction. There is discussion on over-production of food, that an area the size of China produces food that is wasted each year, and that the energy and greenhouse gases to produce it could be saved.  There are moments in the audiobook that McGavin reverts to describing in detail the autecology of various species, such as the honeybee (excellent account), the cochineal beetle, the stag beetle, the galls of oak trees or the Colorado Beetle – all a background for a younger audience, and harking back to this lecturing days.  He gets very annoyed at the phrase Save the Planet when the planet is actually fine, it has looked after itself OK for the last 4.5 billion years and insects in general are always OK. As a good storyteller, McGavin tells us of his adventures mothing in Papua New Guinea where he is ‘ecstatic’ by the diversity of moths to his moth trap, or under the clear skies of Africa. McGavin gets us up to date with neonicinoids in the environment and their potential effects on honeybees. A lot of what he says is backed up with reference to recent research. He quotes E.O. Wilson (we all do) and John Muir; he talks about ‘bee vomit’ (honey) from honeybees and the ‘insect spittle’ (silk) from the silkmoth now extinct in the wild. These descriptions are very appealing to youngsters, and to this end the book is pitched for a very general audience from children right up to all adults interested in the natural environment and what is happening to it, even ecologists, entomologists and naturalists.  There is a very good section on ‘A Natural Pharmacy’ (the audiobook is full of named sections) where the plant world is shown to be a natural pharmacy of useful ‘secondary plant substances’ or scientifically as Prof Philip Stevenson says are ‘Secondary Metabolites’. This is an area much to my own interest especially with the suite of carotenoids and their overlooked importance in inverts and humans.  Much discussion is had on caffeine which in concentration is antagonistic or a deterrent to honeybees (for instance) but in dilution appears to be a stimulant to improve the bee’s carrying out its pollination duties.

There is measured frustration in McGavin’ s voice that the message of the insect decline is not being heard or heeded, as we have all been banging on about this for decades. There have been other voices before about the loss of habitat, such as Marion Shoard, Norman Moore, Graham Harvey, and more recently Elizabeth Kolbert on the 6th extinction and Dave Goulson (with his Silent Earth), but McGavin’s is more a more direct and approachable, well-rounded interpretation, as always backed up with scientific evidence, even though the truth is not heeded.  This topic needed to be aired as an audiotape (14 hours), even if it’s dark message that can be listened-to during a long car journey through a clean windscreen. It has great educational value and should be required ‘reading’ for all schools.

British Moths by Lowen

British Moths, A Gateway Guide, a field guide to the common moths of Britain and Ireland.  2021. Bloomsbury Wildlife. 224pp. £15.29 on-line.   Ring-bound and e-edition available. ISBN 978-1-4729-8738-9    9 781472 987389   A review

My review copy arrived just after the Saharan dust arrived on 16 March 2022 and I had installed the moth trap to see which North African moths had hitched a ride to the UK.  So I got out this book and tested the identification. The book is arranged seasonally, that is to say if you are starting to trap moths in 2022 then it begins helpfully with ‘Spring Moths’ – and yes a lot of the moths were present and easy to identify.  The author has illustrated pages such as ‘chestnut-brown noctuids’ and ‘beige and reddish-brown noctuids’ and ‘spring-like quakers’. The noctuids are a big and diverse group and there are many overlapping and confusing features thrown in with individual variation, so many of the similar-looking species are a nightmare for moth newcomers. The ring-bound nature of the book is good for use in the field when opening a moth trap and examining species in the presence of fascinated ‘mothers’.  Although the UK list of moths is about 2,500 species, this book includes 350 species of the most common and eye-catching species. Some of the common micros are also included. The standard of the close-up photographs is good and the identification features are shown in the photos with precise annotations. James Lowen is already a Bloomsbury Wildlife author who also written ‘Much Ado About Mothing’ (also in 2021). Lowen comes out with some intriguing categories for the ever-confusing noctuids through the seasons, where he calls them ‘Little Brown Jobs’ – referring to the ornithological parlance for difficult avifauna. In comparison, birds are easy to identify, moths are so much more difficult and more appropriate for the epithet.  Moths have taken diversity to a completely different level. The whole range of common moths are included from hawk-moths, emeralds, waves, pugs, footmen, tigers, sallows and underwings. At the beginning of the book there is a section on the joy of moths, how to see moths, and how to identify moths. There is a subject index, but no glossary or further information. There are other moth identification books that go into much greater detail, but this is a neat, useful and trap-side identification book in full colour, which is fits nicely into a jacket pocket, and is recommended for all beginners and amateurs who venture into the great world of moths.  No, no Saharan moths graced my trap, but many local common moths were present and the book was found to be useful.   John Feltwell.

Butterflies of Serra Dos Orgaos, 2020

Bizarro, J. and Martin, A., 2020. A Guide to the Butterflies of the Serra Dos Orgaos, South-eastern Brazil. REGUA publications. ISBN: 978-0-9568291-2-2  389pp  Review

As guide books go, this is not one for the pocket, but this is a magnificent tome (20x24cm) which depicts in perfect colour all the known butterflies of this part of SE Brazil. It is in English, but if it were in Portugese as well it would be twice as long.

The book includes a total of 923 species of butterfly recorded to date from the Serra Dos Orgaos in the State of Rio de Janeiro.  This includes the very difficult skippers (120 species) which have only been given general descriptions. That leaves 803 butterfly species are described completely with Scientific and Common names, descriptions, similar species, distribution and ecology. There are 58 species which are listed as Threatened in Brazil, and 14 of these which are found in the area, are included too. There is so much natural habitat in the REGUA lowlands to the ridge line of the Organ Mountains (2,260 m) to be explored that many more butterfly species will be discovered. Butterfly lovers wanting to discover new butterfly species need to head for the REGUA reserve.  Also included in the book are 5 butterfly species that are waiting to be described and named, one Symmachia sp. three satyrs and one Gorgythion skipper.

The authors include Dr Jorge Bizarro with a background in medical entomology and a passion for butterflies, and Alan Martin FLS, a renowned ornithologist and professional accountant who has fully embraced an enthusiasm for lepidoptera with a background in helping some of the leading UK and global conservation NGOs.  Other publications from REGUA include ‘A Guide to Hawkmoths of the Serra dos Orgaos’ in 2011 and ‘A Guide to Dragonflies and Damselflies of the Serra dos Orgaos’ in    and ‘A guide to Birds of the Serra dos Orgaos’ in 2015. So this is REGUA’s fourth publication, a credit to their professional output.

Extensive field work carried out by the authors and their many colleagues at the field station in REGUA has enabled this comprehensive compilation of butterflies of the area. It is in an area that Charles Darwin visited, and it still offers naturalists alike the opportunity to explore, discover and describe wildlife. The illustrations in the book, some 88 plates are key to identifying the species, all reproduced in superb colour, 15 species a page, almost all mostly shot in the wild. The range and diversity is stunning, but then the quality of the hinterland of REGUA is of perfect Atlantic Rainforest, a rare and declining habitat recognised as being in the top five global biodiversity hotspots in the world; there is only 16% of Atlantic rainforest left (it used to stretch south from the mouth of the Amazon), and REGUA with its 18,000 acres seeks to conserve (and enhance with native plantings – over 624,000 trees planted to date) what is left.  Bringing back the native flora is key to supporting and expanding the potential of butterflies and moths.  The new acres of wetlands increases the biodiversity of insects across many orders of insects including lepidoptera.

The guide will be immensely useful to visitors to these neotropical tropical habitats in Rio de Janeiro state and all those who wish to start identifying from their digital images.  As stated, the book is too large to have in a knapsack (it is over 1.1kg) but a copy needs to be in all field schools, field labs, libraries and university ecology and conservation departments, as a key reference book.

There is a Glossary, Latin Name Index, additional reading and references, and the list of Threatened species. This is a remarkable compilation and sets an important milestone in butterfly research in this wonderful part of the world.

Death’s Head H/Moth … 2021

Howse, P.  2021, Bee Tiger: The Death’s Head Hawk-Moth through the Looking-glass. Brambleby Books. pp119. ISBN  978-1-908241-62-7  9-781908 24 1627  £13.99



There have been precious few books on a single moth, with the exception of perhaps the Silk moth, Bombyx mori or one of the moon moths or emperors or some of the glamorous day-flying moths. This is not so much an entomological treatise on the Death’s head hawk-moth than a comprehensive discourse on skulls, bones and all interpretations of these patterns and messages as we may see them;  it is all in the sub-title, ‘through the looking glass’. Mimicry, which is the author’s passion, and nature’s gift, is full of visual interpretation of the dynamic living world and thus subject to vagaries in our understanding. There is a tendency to anthropomorphosise. And so it is with this hawk-moth. It is a large lumbering moth which has evolved to be a honey thief within honeybee colonies. For a large lumbering moth it must have an acute sense of smell to search out and find honeybee colonies, and as for its large size, it does need this to go deep in a hive and plunder the goods. It may of course be too big for bats to handle, as bats weigh less.  Unusually for hawk-moths the death’s head has a very stubby proboscis which it pierces the capped brood and feeds unmolested by the bees. Philip Howse, describes how the morphology of the moth, and its sounds, mimic the piping of the queen bee and it may thus sooth the behaviour of the colony.  Of the bright colour of this moth, the contrasting yellows and black we are told mimic the warming colours of wasps and hornets – more for the daytime predators, birds and reptiles than bees.  And, as for the scary death’s head, this is also for daytime predators – especially if seen from in front, rather than as we conventionally view a moth as settled or set. The classic medusa head of ancient Rome and Pompeii are invoked, especially with hair entwined with snakes. Photos of heads and skulls are shown, including Picasso’s ‘In Voluptate Mors’. Philip Howse is a poet and he publishes a few of his lines as well as many others, and cites quotations from a host of others including Homer, Faust, Proust, Jung, Darwin and more recently Miriam Rothschild who also was enthralled by the moth.  The book is relatively short with nine blank pages at the back (printing problem?) and there is a bibliography, index and glossary of 28 colour plates.   There are nine chapters, three of which are linked, the honeybees’ tale, the bat’s tale and the bird’s tale – all expressing how mechanisms have evolved in these groups over millions of years to feast and forage. The author goes to extraordinary lengths to describe the colour vision of birds and then at the end of the chapter to show how birds might view the moth. The same for the bat’s tale chapter, and exposé of the bat’s capabilities in detecting prey on the wing, all backed up with up to date technical research and discoveries.  With an exciting cover, and a good in-depth read around the subjects, this book will appeal to entomologists, naturalists and members of the general public. The author is Professor Emeritus in Biological Sciences at the University of Southampton and is the author of a number of general natural history books.


Much Ado About Mothing

Much Ado About Mothing; a year intoxicated by Britain’s rare and remarkable Moths. 2021. By James Lowen. London, Bloomsbury Wildlife. £18.99. 384pp.  ISBN 978-1-4729-6697-1   9 781472 966971


We have already had a butterfly enthusiast run around Britain in a year to shoot all the butterfly species, in the name of Patrick Barkham in his ‘The Butterfly Isles’; he reviews this book on the cover as ‘Here is colour, wonder, surprise – and fun’.  Now we have James Lowen setting himself the target of chasing rare and remarkable moths around the islands, from Cornwall to the Cairngorms. Not that he is chasing all the moths – an impossible task with about 40 times more moths than butterflies.

Lowen was initially inspired to all things moths by a poplar hawk-moth which he had to hand. Most people are enthralled by the beauty and evolution of animals, and essentially this is what this book is about, it celebrates the enthusiasm that one man has for moths. James is completely moth-centric. He exudes moth enthusiasm the way other people pursue particular wildflowers, fungi, bryophytes or even tardigrades.

James is an all-round naturalist, whose grass roots were in Yorkshire which set his seed for the living world, and he has explored South America and the poles; he writes for various papers and has a number of books to his name.  His conversion to moths has been recent and profound, not least encouraged by the enthusiasm of his daughter, Maya who figures in the book, especially in the eight pages of colour photographs in the middle of book which figure 15 species of moth, but which mostly shows venues, equipment and techniques. Oh for more illustrations for a group with 2,500 species.

There are 20 chapters starting with winter-spring and ending in autumn. Although only four chapter headings give a clue about the subjects (Hawk-Moths, Kentish Glory, Clearwings and Blues – read Clifton Nonpareil), the rest are very discursive and story-like, on how a site visit was formulated, with advice from whom, how they got there, what it was like on arrival, the type of habitat and finally the exaltation of finding the target.

The book is well researched and his sorties to various far flung habitats is usually to link up with regional moth experts to explore last known locales and pabula. Local contacts from wildlife groups and from Butterfly Conservation (which also conserves moths) and RSPB (yes moths too) and national projects such as ‘Back from the Brink’ are often the source of his targets.  He has included classic lep stories and research involving Miriam Rothschild and Bernard Kettlewell and waxes lyrical about the new arrival the horse-chestnut micro. Where would he be without his treacle ropes, actinics and other entomological paraphernalia.

His writing is florid and descriptive to an intense or even excessive level; his descriptions of moths are flowery and romantic, whether it is the Old Lady, Scotch burnet, Netted carpet, Crimson underwings, Merveille du Jour or hawk-moths. In his quest to find moths James clocked up 14,000 miles over 258 days and visited 139 locations across 27 counties of equivalent.  A job well done.  But only touching the surface of moth biodiversity.

The book is ideal for general readership. A good read for moth-ers without the scientific clutter. The book will be of interest to naturalists, entomologists and lepidopterists and as a book on moths it is unique and unrivalled. There is an index, a bibliography and list of acknowledgements which runs to four pages. The cover is exciting and colourful. It’s a good book to hand, especially with the colourful and exciting cover.

From the flyleaf blurb it says…’no animal may be better placed to inspire the environmentalists of the future.’  Good luck with that then!  Moths will still continue to have a bad press (as most are brown, hairy and scary to the general public), even though they are more biodiverse than butterflies and in many cases more colourful than butterflies such as the day-fliers which James covers in his travels.  Let’s hope this book has started a revival in their fortunes.


Ladybird Books & App

 Three ladybird books & and a Ladybird App. – all coloured red! Two of the books are by different Helens.

 Ladybirds’ by Michael E. N. Majerus. Collins, 1994. ISBN 0-00-219935-1 (originally £14.99 in pb) 367pp.

 Ladybirds’ by Helen E. Roy, Peter M.J. Brown, Richard  F. Comont, Remy L. Poland and John J. Sloggett. 2012. Naturalist’s Handbook 10. Ladybirds. Revised from Majerus and Kearns 1989. ISBN 987-1-907807-0707. 9 781907 807077. Reprinted by Pelagic Publishing. £22.98 142pp

 A Field Guide to Harlequins and other Common Ladybirds of Britain and Ireland.’ By Helen Boyce. 2021. Published by Pelagic Publishing. A Pelagic Identification Guide.  ISBN. 978-1-78427-244-9   9 781784 272449. 106pp.


‘European Ladybirds App’ v.   2021. v1.1.1(1) The app was hand crafted by Karolis Kazlauskis, and authored by a team of 14 scientists from UK, ITA, CZ, SK, BE and PT with financial support from the Centre for Ecology & Hydrology (CEH) and Anglia Ruskin University (Faculty of Science & Engineering). Two of the authors, Roy and Brown are co-authors of one of the books above. It is free, simple and quick to download and is conceptionally easy to use. Thirty nine species and forms of ladybird are illustrated with common and latin names. A digest on each species describes size, legs, colours, spots, plants on which it is likely to be found and and food, and habitats. After an initial registration with name and address the app knows where you are an applies a 6-figure OS map reference, and all that is required is to note which species found, in what sort of habitat (a choice is given) hit send record, adding a photo if you wish. This is a user-friendly app which you can carry on your android for field identification and reporting records.

There are other ways to record ladybirds, for instance in the long running UK Ladybird Survey via or via the iRecord app.  

 The classic and highly collectable book on Ladybirds by the late Michael E.N. Majerus stated in 1994 that there were 42 species in Britain. It remains the best original book on ladybirds. The figure is now updated by Helen Boyce’s book who states that there are now 47 species of ladybird in Britain and Ireland, but only 26 of them, now including the Harlequin are conspicuous – thus setting the scene for her book.

 The Helen Boyce book is a short but succinct book of colour photographs and explanations in double-space text for identification; the Helen Roy et al book is much longer and more of a digest and thorough scientific treatment of ladybirds with chapters on ladybirds in the environment, their enemies, variation, population and evolutional biology and identification with keys to adult British ladybirds, all adult British Coccinellidae and larvae of British ladybirds. The field and lab techniques are particularly useful. The Helen Roy book is a fair substitute, and up to date too, for the Majerus book which might be difficult to find cheaply. It is all that beginners would need to get started on ladybird identification, a good concise book.

 If you have difficulty identifying a Harlequins from other Coccinellids there is a 32 pages of subtle chararacteristics in the Harlequin book, such as i) only Harlequins have two ‘shoulder spots’, ii) they never have ‘Angel Wings’, iii) they are 5-8mm long, iv) ‘the only black ladybird that has full, round white ‘cheeks’ is the harlequin v) harlequins do not have white spots on their wing cases vi) they have ‘pinched’ dimples on the rear of the abdomens and viii) they have a lip on the elytra.  There is also a photographic guide on how to distinquish harlequin larvae from other ladybirds, and the most interesting one are the branched spines known as scoli. There are references and index in both of the more recent books.

 All readers have a an affinity with ladybirds, and after befriending an individual the question is often which species is it. Both books will help at this stage, though in the field the app is invaluable and the best choice, even though both books will fit into a jacket pocket.  The classification of ladybirds according to the number of spots is deceivingly simple, but as with many things in nature the more you look the more alternatives come forward.

 All these books are useful.  In a world before Harlequins (introduced into the UK in 2003 and spread to many areas at 100km a year) and in a world that Dr Majerus did not know about, the widespread occurrence of Harlequins introduced another level of variation amongst ladybirds, If you thought that the range of variation amongst ladybirds was great, then Harlequins are at another level. Thus the need for a book on Harlequins and how to distinguish them. This aim has been discharged well.

 Do the books have an answer to this intriguing colour variation?  Helen Roy et al say that factors producing these variations are unknown in many species’. There is much discussion about genetic effects, but the environment has something to do with it too. It is ‘expected that ladybirds will be negatively affected by climate change’ and it was interesting to learn about the dark melanic forms of ladybirds, especially that ‘darker forms are associated with cooler humid climates’.  

 2-spot and 10-spot and the Harlequin are the most variable of ladybirds, and some reliance is had in the Helen Roy book of the old classification of the German entomologist who listed 119 colour forms in his research in 1926-37. By 1945 more than 200 colour forms of the Harlequin ladybird had been listed for Europe with only three in the Britain.

 The colour red has been evolved especially for aposematic purposes by these ladybirds, and also in combination with black and white, and yellow. It is as if ladybirds have cornered the red market for defence in a lively world of predators, but it is not the case. Many other insects use red for great effect.






Pollinators & Pollination 2021

Pollinators & Pollination. Nature and Society. By Jeff Ollerton. Published by Pelagic Publishing. ISBN 978-1-78427-228-9.  2021. 286pp. £24.25

As the blurb states Prof Jeff Ollerton is ‘one of the world’s leading pollination ecologists’ who works at the University of Northampton. Most of his 30-year’s research is poured into this major work and it has plenty of graphs as an evidence base for his ideas and theories. He states that he has pitched the book ‘at a very broad audience, and is intended to be comprehensible to anyone with an interest in science and the environment.’ He has succeeded admirably in this aim, and it covers an area not explored by other bee experts whose work is discussed. This is the first time I have seen a blanket acknowledgement for all his academic contacts rather than mentioning bee experts by name. This is not just about bees and pollination – though it may seem that way as Apis mellifera is a major pollinator – it is about all pollinators, birds, reptiles, mammals and invertebrates. There are an estimated 350,000 terrestrial vertebrates and invertebrate species that move pollen, for the estimated 352,000 species of flowering plant: so flowering plants are well catered for and co-evolution is patently evident.  Invertebrates are the commonest pollinators: the estimated number of species, from the largest to the smallest as listed, are Lepidoptera (141,500 species), through Coleoptera (77,300), Hymenoptera (70,000), Diptera (55,000) and Thysanoptera (1,500 species).The book has 14 chapters ranging from ‘To be a flower’ to ‘Agricultural Perspectives’ to ‘New Bees on the Block’ – mostly about the Tree Bumblebee and The Ivy Bee, and the 17 species of bee, wasp and true-flies that have turned up in Britain since 2000. A lot of the collation has been by BWARS.  He even has a chapter on ‘The politics of pollination.’ There is a section on neonics in which Ollerton reminds us they are chemically similar to naturally occuring nicotine, which used to be used a long time ago. He debates all sides of the issue, but unfortunately just missed the latest UK authorisation of neonics prior to publication. In reviewing the literature he shows that some recent research ‘strongly implicated as a likely driver of those declines.’  It is good to see that Buglife-The Invertebrate Conservation Trust is mentioned, as well as the National Pollinator Strategy. As the author states ‘I have tried to provide a personal, state-of-the-art overview of what pollinators are, where they are to be found, how they contribute to the pollination of both wild and agricultural plants, supporting the wild ecosystems…’ etc.  There are just a few colour photographs dotted about the book, but it really offers extended essays on topics rather than pretty photos that can be found in a host of other bee books.   The References run to 32pp and there is an index.

Oates’s Purple Emperor

Matthew Oates. 2020. His Imperial Majesty, a natural history of The Purple Emperor. London, Bloomsbury Wildlife. 416pp £20.00 HB

The author, retired from The National Trust, is the UK’s expert on the Purple Emperor, and this book reflects his particular obsession with ‘His Majesty’. The title is borrowed from the Victorian era. The sub-heading accounts for the minutiae of the species whose preferences have led Oates a merry dance amongst the woodland, scrub and farmland throughout the UK, notebook in hand over the last few decades. Oates says that the book could not be written without his involvement with the wilding project at Knepp (West Sussex), and Isabelle Tree, the co-owner of Knepp, has written a lively Introduction. Of Knepp he says it has become the foremost Purple Emperor site in Europe, and later says that a private estate in East Sussex is the best breeding ground he has ever seen. Oates has had to change his views on the habitat preference of the Purple Emperor, away from its perception as a forest species, even though he variously says in the book that it is an arboreal species and a canopy-loving species.  He argues that the species is now widespread and not rare any more, and he champions the species as the National Butterfly. What about the Swallowtail, or Large Blue? Oates is quick to say that various lepidopterists are wrong or have differing opinions: Heslop, Frohawk and Pratt. Of Heslop he says it is a pity he did not publish his notes, and Oates goes on to rely heavily on Heslop’s work. As the author points out, the book is clearly written in an anthropomorphic manner with a few concessions to science, principally the reproduction of distribution maps. His penultimate chapter is on Conservation Issues, but you have to work hard to find any bullet points on how to conserve the insect, mostly focusing on sallow management. He says that he is not convinced that the species actually ‘needs some thinking and practices of contemporary nature conservation.’ That said Oates argues for a rigorous peer-reviewed scientific work on the ecology of the Purple Emperor and gives useful tips for future research topics. This book, that embodies his almost complete dedication to the species, will not do, even though the 17 chapters are packed with day to day factual ecological information from his exhaustive and laudable time in the field over the last few decades. The book is a little repetitive and could have been more tightly edited, and there are bits about Christine Keeler, and Pygmy Hippos that could have been edited out. Many lepidopterists are mentioned, but some like the Rothschilds (Charles and Miriam) are not. Miriam was also a lover of butterflies. There is a short glossary, references and further reading, but the best, previously unpublished section is the Appendix which runs for 50 pages and describes county by county, wood by wood, the varying and increasing range of the species that has not been collectively drawn together elsewhere. Excellent. The book is an interesting read and will appeal to all the followers of Purple Emperors, of which there is a fan club.

Wasp by Richard Jones

Wasp. Reakton Books Ltd. 2019. 207pp

Almost 100 titles in the ‘Animal Series’ have been published by Reaktion Books, and they all good reads, and collectible. The author is a leading UK entomologist and has already written the ‘Mosquito’ book. The books follow a familiar format showing how the species has been illustrated and written about from the earliest times, in this case since the Egyptians, 5000 years ago. The black and yellow wasp ‘brand’ is explored, and even the book cover is black and yellow. The book has interesting chapters on ‘warning colours’, ‘paper architecture’, ‘tabloid mayhem’ and ‘what is the point of wasps’; on the latter it is pointed out that they are part of biodiversity and are useful predators of other insects. The book covers wasps worldwide (the 4000 species of vespid hymenopterans) and in relation to the recent arrival of Asian Hornet into the UK, this is up to date to 2019. For those who like wasps, this book is an excellent exposé of their capabilities, their form and function, and their niche in the world. The wider context of wasps in the world is rather more interesting than the entomological detail.  In the next edition the small tortoiseshell on p. 51 should be corrected to the large tortoiseshell.
