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

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

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

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

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

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

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

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

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

Interview with botanist James Byng, author of The Gymnosperms Handbook

James Byng
James Byng in Zambia looking for Syzygium

James Byng is the author of the new Gymnosperms Handbook and a founding member of Plant Gateway, the botany organisation that published this, and his previous book, The Flowering Plants Handbook (out of print – new edition pending). In this interview he tells us about his work with Plant Gateway, raising the profile and accessibility of plant research, his own work with the genus Syzygium, and a day in the life of a working botanist.

You are a founding member of the Plant Gateway team. What is the vision for this botany organisation?

Taxonomic research is an underfunded and underappreciated branch of science and so few plant taxonomists are employed today in universities, and most national botanical institutions are cutting staff. However, the need to document the world’s species diversity has never been greater with as many as a fifth of all known plant species estimated to be threatened with extinction.

We believe at Plant Gateway an important step in slowing the biodiversity crisis is making plants more relevant and more accessible to people. It sounds simple but plant research in general is never quite appreciated as much as research on animals or in other scientific disciplines. But plants are fundamental for our own existence and continued survival on this planet, and we still barely know anything about most of them. Plant Gateway was founded for passionate like-minded taxonomists to make sense of the complicated botanical literature by publishing practical literature, running affordable and engaging identification courses, and undertaking taxonomic research with the aim of bringing it to a wider audience and making significant strides in our knowledge.

Who are the Plant Gateway courses for and how can they get involved?

Whilst training to be a plant taxonomist I witnessed over the years that plant identification skills were rarely being taught at universities anymore despite there still being a huge demand. Even though several courses exist which teach these skills, many of the courses are very expensive and/or taught too much from the specialist’s point of view which scares people off. Our courses are designed for everybody and anybody whatever a participant’s botanical background – all you need is an interest and love for plants! On past courses we have had undergraduate and postgraduate students, university professors and lecturers, horticulturalists, ecologists, Friends of Botanical Gardens and gardeners. We run several 1-day identification courses all over the UK in May and June, and a week long course in Tenerife around Easter time in 2016. Places on these courses can be reserved on our website.

The Gymnosperms Handbook: A Practical Guide to Extant Families and Genera of the World

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Gymnosperms Handbook is the second publication from Plant Gateway. Who is this book aimed at?

The Gymnosperms Handbook is a concise introduction to identifying extant gymnosperms of the world. It is aimed at both specialists and non-specialists; ranging from experienced botanists, ecologists, horticulturalists, biologists and gardeners to students and those people who are learning about and interested in conifers, cypresses and other gymnosperms because they see them in their local parks and forests. So the handbook is aimed for everybody whatever their background.

Part of your own research is focused on the systematics of Syzygium (Myrtaceae). What led you to this particular genus?

In 2007 I was an undergraduate at the University of Aberdeen when I first encountered the genus Syzygium in Zambia while undertaking ecological fieldwork. Since then I have been intrigued by the genus as most botanists seem scared by the sheer number of (known and unknown) species and the difficulty in identifying them due to the seemingly poor diagnostic characters which separate species. The genus is famous for containing the commercial clove (Syzygium aromaticum) and is now the largest tree genus in the world with over 1,200 species. I am now leading a project, with collaborators in the USA, Australia, Africa and Asia, to unravel evolutionary relationships of Syzygium and to document all species in a global monograph.

What does a working day as a botanical researcher look like for you?

A typical working day for a plant taxonomist in the twenty first century varies from week to week. Most of my time is spent with dried plant collections, housed in herbaria, where I sort through specimens collected from past and present field expeditions and document and describe species diversity. I also spend time collecting new data and plants in the field, usually in the tropics, and undertaking lab work where I extract and amplify DNA to understand evolutionary histories. Lastly, but perhaps most importantly(!), I spend time in front of the computer writing up my findings in the form of scientific papers, reports and books. It can be a combination of enjoyment and stress but once I finish a piece of work it makes it all feel worthwhile.

What’s next in line for publication from Plant Gateway?

One of the next titles in our practical handbook series will be a revised second edition of The Flowering Plants Handbook which will include notes on all flowering plant genera, more images, and will follow the soon to be published Angiosperm Phylogeny Group (APG) IV classification system. Also, there will be a practical handbook on ferns and their allies co-authored with my Plant Gateway colleague, and leading fern specialist, Dr Maarten Christenhusz.

The NHBS guide to buying a hand lens

Hand LensThe possession of a hand lens is one of the defining characteristics of a naturalist.

We use them for everything from peering at beetle genitalia and examining floral characters, to examining the arrangement of teeth in small mammal jaw bones. There are a wide variety of hand lenses on the market so how do you decide which lens is best for you? This article contains all the information you need to make an informed choice about which hand lens is most appropriate.

Glass versus plastic lens?

The optical lens in a hand lens can be made from glass or plastic – the plastic lenses are generally more affordable and lighter but are of lower optical quality and more difficult to clean. Good plastic hand lenses, such as the Plastic Double Magnifier, are perfect for youth groups and schools.

How many optical elements?

Canon 400mm

An element is an individual piece of glass within a lens. When you look through a high quality camera lens you will typically be viewing what’s in front of the lens through four to six lens elements, as well as other elements used for focusing and zooming (see image below right).

Paul Canon EF 400mm f/4 DO IS USM By Paul Chin

Hand lenses are constructed with one (singlet), two (doublet) or three (triplet) lens elements. Each element is specially shaped to correct for a particular type of optical distortion so the more elements, the higher quality the image.

Magnification

A 10x magnification hand lens will be more than adequate for most purposes. Higher magnification lenses tend to be harder to use but are very useful for viewing extremely small objects. If you are unsure of which magnification you need, or think you may need several different lenses, you should have a look at the x10 and x20 Duel Singlet Loupe or even the x3, x4 and x5 Triple Loupe.

Lens diameter

Large diameter lenses provide a wider field of view which means that they are easier to use but they are slightly more expensive to produce.

How hand leOpticron Hand lens, 23mm, 10x magnificationnses are named

Hand lenses are named like binoculars, with both the lens diameter and the magnification included in the name. e.g. the Opticron Hand lens, 23mm, 10x magnification has a 23mm diameter lens and provides 10x magnification.

 

Using your hand lens

Finally, a quick note on hand lens technique. To use your hand lens correctly (this is particularly important when using high magnification lenses) hold the lens close to your eye and then either a) move the subject closer to your eye until it comes in to focus or b) move your head (and the hand lens) closer to the subject until it comes into focus. It’s easy with a little practice so don’t get put off if you find a new hand lens difficult at first. Expect to get close up to what you’re examining – it’s quite common to see naturalists crawling around on the ground to get close to a plant they’re identifying.

Keeping your hand lens safe

It can be very hard to find a much-loved hand lens dropped in long grass or woodland. To prevent this traumatic experience, we recommend a lanyard for your hand lens – this has two functions: a) if you have it round your neck you won’t drop it, and b) if you put it down somewhere the bright blue lanyard is easy to spot.

The table below provides a guide to the hand lenses sold by NHBS. More information and specifications of each can be found on the website.
