Aimed at both the general reader and amateur naturalist, this guide offers information on observing and identifying 150 of the most commonly encountered butterfly species in Britain and Europe. Each butterfly's habits, range and important characteristics are described, while colour paintings show each butterfly in detail. There are sections on the four stages of the life-cycle of butterflies and on breeding butterflies. Sound advice on conservation issues is also offered. The book can be used as both a home reference and a pocket companion in the field.
