A very fine photographic guide to all the Dragonflies and Damselflies of Britain and Western Europe. This visually impressive encyclopedia is a must-have for Britain's army of dragonfly-watchers. Written at an advanced level, this book contains keys, first-class photography, and highlights to key identification criteria in the adults. Very unusually, nymphs are also afforded this treatment, making this a truly unique resource for anyone interested in freshwater ecology. There are also detailed diagrams of wing venation - crucial for some identifications, rarely covered in other guides (and never with this sort of clarity) - and plates showing confusion abdomens, a superb resource.
