This guide is the third volume of a series on Hymenoptera of Europe. A key allows the identification of the 14 subgenera of bumblebees present in this region. Then, for the first time, there are detailed identification keys for the 79 species of bumblebees found in Europe and neighbouring countries.
Each species is presented with all its geographic variations as well as with notes on its ecology, behaviour, flower preferences and conservation status.
Original photos are included for each of the West Palaearctic region species. Some extremely rare bumblebees are pictured for the very first time. The book also features many colour plates to help readers recognise over 240 forms and subspecies
