At least a field guide which allows to identify with confidence all the butterflies flying in Europe.This book is basically a subdivided determination key. The beginner can follow it step by step untill he gets the name of the butterfly, the keen entomologist can directly go to the relevant genus or species. There are about 1300 colour photos of living butterflies with useful lines pointing to distinguishing features. For each species the text, photos and distribution map are presented together. The distribution maps are precised and updated, with detailed maps for local species. The author's aim is to enable the identification of all species in the field without killing them, and there are genitalia drawings for the more difficult species with a method to check them without killing. This pocket field guide (13 x 19 cm, 352 pages, 500 grams, softcover) has everything to become the ideal companion of your travels and excursions.
