Book Review - Britain's Butterflies 4th ed. 'WILDGuides'

Autumn may not be the ideal time to publish a Butterfly book but delayed by COVID-19, the 4th edition of WILDguides Britain's Butterflies is now available and it's a must have!

A lifelong interest in Butterflies began for me in the 1960’s when as a young budding naturalist ‘The Observers Book of Butterflies’ became a source of wonder and inspiration. Fast forward another forty years to the millennium and with the dawn of the digital age, I bought my first digital camera and needing a new reference book I bought the WILDGuides first edition of ‘Britain’s Butterflies. Using photographs, cleverly arranged on a montage of food plant flowers or habitat, this edition would still be adequate for the novice but times move on. The fourth edition of this ground-breaking book has now evolved into the benchmark for modern photographic field guides. The original duo: David Tomlinson and Robert Still, joined by David Newland and Andy Swash from the second edition have ensured the book keeps pace with modern taxonomy and uses the best available photographs. The foreword, written by Julie Williams CE of Butterfly Conservation, reminds us of their alarming decline around the world and the need to conserve them - hopefully their work will ensure that future generations, are inspired by butterflies too.

Right from the start, this book looks and feels well made with a soft yet durable cover (flexibound). Weighing in at 610g and measuring 8 ½ x 6”, it will easily slip into a backpack. There are over 600 high quality colour images and 76 colour distribution maps throughout the 256 pages which cover in detail, the identification of all 59 butterfly species that breed regularly in the UK in addition to former breeders and migrants. Written with an easy-going style, it will appeal to the beginner but is worthy of a place in the bookcase of the more advanced observer. The sections on food plants and on recording / monitoring have been expanded and the species order has been revised to reflect the latest taxonomy.

The introduction sets the scene for making butterfly identification as simple as possible then covers how butterflies and moths differ and their biology. The sections on ‘where to look for butterflies’ and their identification by ‘type’, separated into six families and then eleven broad groups (eg ‘Browns , ‘whites and yellows’, skippers etc) is a sensible approach for the beginner. A brief section on colour variation and aberration whets the appetite for more advanced identification. References to other books are included, which provide more depth of information. 


The bulk of the book deals with species accounts which are covered in an exemplary, consistent format and how appropriate that the first section commences with a favourite for many observers - the Swallowtail. 


Where this book excels, is the ease with which species can be found with each having a double page spread, information on the left and relevant images on the right.

The conservation status, legal protection status and measurements of each butterfly are followed by an up to date distribution map which colour codes the main breeding range, secondary breeding and for extinct species, the former location. The tried and tested ‘clock diagram’ uses another colour coded scheme to clearly denote when each life stage occurs, noting that in the north of the species range, this may be slightly later. Tips on where to look for the species plus possible confusion species followed by a concise summary of the species’ status in Britain and Ireland.

The colour plates are superb, males and females are distinguished where possible, sometimes with annotated close up images or including both upperwing and underwing shots when appropriate.   Some images of subspecies (eg Silver-studded Blue and Grayling) and forms (eg Comma) are included and a list of subspecies is included in the main national list (page 237 onwards). 


Former breeding species, rare migrants and vagrants occupy the next thirty pages, detailing their likely origins.  The very rare migrant, Scarce Tortoiseshell, is included in this section and is only ‘new’ species addition since the first edition. There was an exciting record of sightings at different places in south-east England in 2014. Southern Small White gets a mention too, expanding its range rapidly in Europe and recorded near Calais in 2019. Some records of either may of doubtful provenance but who knows whether these small advance parties could one day become UK colonists?



 A section on food plants, details the associations, sometimes unique, of caterpillar species with a particular flower or tree. The food requirements of the adult butterfly may differ from that of the caterpillar as the priority is finding good sources of nectar. Searching for the correct food plant may help the observer find the target butterfly? The early life stages of butterflies are covered next with close up images of the eggs, caterpillars and chrysalises, noting when and where you might find them.

The concluding section features a complete list of British (and Irish) butterflies, tips on butterfly watching and photography, butterfly conservation plus recording and monitoring. Having found your butterfly and photographed it, the online presence of butterfly conservation and regional groups ensure images can be enjoyed by a wider audience and these act as ‘news’ of emergence and productive sites.

Published by Princeton University Press on 14th September 2020, the target price of £17.99 can currently be found as low as £13.40 at various outlets. Be sure you are buying the correct edition, with a picture of the Comma on the cover!

This field guide is an absolute ‘must have’ for anyone contemplating a wish to identify and learn more about butterflies. Whether simply observing butterflies in the garden, the countryside, local nature reserves or whilst on holiday, it contains all the information you need when in the field to identify your ‘finds’. For the price, this fourth edition is a snip and will bring you right up to date! Happy hunting next spring…

Venus Pool - Brambling arrival

The pool was very quiet today but at least there was a fair bit of activity in the arable field hedgerow. Highlight was my first Brambling (female) of the Autumn (one was also reported the previous day)




A couple of Yellowhammer too...


Plus at least 20 Reed Bunting.




Red Kite have become 'daily' birds nowadays, how times change...





Plus a female Sparrowhawk hunting...

Venus Pool - Great White Egret

It had been a busy week but blue sky and the prospect of checking out some gulls for Dave's Leucistic LBBG  tempted me to get down to VP late morning. There was not a single car in the car park! I made my way to the causeway and apart from a few Geese and the Cetti's Warbler which flew the gap once more, all seemed quiet! That is until I checked the bank left of the members hide. Crikey that's a large Egret... has to a Great White Egret! It was but sadly in and out of view most of the time time until a Heron wandered in - inspiring a bit of action...


The casual approach by the Heron failed to daunt the intruder...


But with a bit more aggression, the local had his way!


Giving me a chance for a couple of flight shots!




The Egret kept his head down for a while but it's not easy to hide when you can stand to a good metre tall!



And you have no chance, if you choose to fly nearer, casually marching over the island as if you own it?


I bet you can guess what's coming?


Yep, here we go again... 


...and I get another series of flight shots :-)




Such beautiful angelic birds!

I was then distracted by the sight of 100+ large gulls dropping in, time to give them the once over...

Venus Pool - Caspian Gull!!!

A few more words than normal, this was a special gull to round off a great session at VP!

Taking a break from the GWE, I could see the incoming large Gull flock was mostly Lesser Black-backed Gulls, now mingling with the local Black-heads. There was one individual gul however standing out from the moment I started scanning them as it strode purposefully or should I say strutted amongst the flock... 

There he is, nicely on a line the Great White Egret! Herring Gull type but standing tall on gangly pale pink legs...


Often a pointer of something interesting, a gull your eyes instantly pick out of the pack!


Zooming in, more features: head shape, long almost parallel bill. It look good for adult Caspian Gull!!





The only missing feature was the primary wingtips which on this Gull were conspicuous by the absence of outermost feathers! I must have spent close on an hour trying to get a decent wing-stretch or two or preen to get a glimpse? I had now been joined by John Martin, and we both agreed, it was looking good for Caspian but we were hampered by the bright sunshine!  Eventually, I've never been so pleased to see a cloud roll over, life became a bit easier! The following images were sorted during the evening and sent to John and Tom Lowe to pore over!


The upperwing distribution of black on the wing tip, including a complete black band across P5 - another feature looking good for Caspian!


And then the clincher pic. With the this angle you can see the three emerging outer primaries, each showing the correct pattern for Caspian!


Tom chose this one to weave his magic on his mobile phone (see below)! Every picture tells a story... The long white tip to P10 and the tip of whitish tongues on the underside of P9 and P8 visible...


There you go, courtesy of the Gull wizard himself! Thanks Tom!

It was a Patch tick for me, in fact a Patch tick for anyone. A new bird for the Venus Pool Reserve list!

To complete the story, it's also the same Gull that Tom found from his garden a few days ago (29th September) so it looks like it's hanging around! Keep your eyes peeled folks!

Oh and if you want something to pass the rainy weekend away, type 'Caspian Gull' in the search box top LHS of the top of the blog header...

Venus Pool - Stonechats

The tables were turned today with the Whinchats remaining distant whilst the group of three Stonechats (male and two 1st winters) showed really well!




The adult male was determined to outdo the others!




Eventually perching where the background was more appealing...





Even got a quick call!

You learn to appreciate birds which are common elsewhere but difficult on Patch!

Venus Pool - Chats

 Quite a bit of movement going on at Venus Pool recently but thankfully the Whinchats (2) and Stonechats (at least 4) were not going anywhere else in a hurry!

Never close, I had to settle for medium range efforts!




With the Whinchats for once giving better views...








I was just about to leave when a dark raptor broke the skyline on the 'hill' of the arable field...
