The Bees of the World is the definitive reference work on the apiformes. Written by Charles D. Michener, the world's leading authority on bee systematics, The Bees of the World is the only comprehensive, worldwide treatment of all groups of bees -- 1,200 genera and subgenera, including more than 16,000 species. In extensive introductory sections, Michener examines the evolution of bees from wasps, the relations of the families of bees to one another, the evolution of bees in relation to that of flowering plants, the nesting behavior of solitary and social bees, and the structure of immature and adult bees. Drawing on these considerations as well as the fossil record, he speculates on the attributes of the protobee, the common ancestor of all bees. He also cites the major literature on bee biology and describes the need for further research on the systematics and natural history of bees, including their importance as pollinators of crops and natural vegetation.
 The greater part of the work consists of an unprecedented treatment of bee systematics, with keys (many of them regional) for identification to the subgenus level. For each genus or subgenus, Michener includes a brief natural history describing geographical range, number of species, and noteworthy information pertaining to nesting or floral biology. The work is beautifully illustrated with 48 color photos of bees, and more than 500 black and white drawings and photographs that depict behavior, detailed morphology, and ecology.
"At least since the time of Aristotle people have been interested in bees because they are fascinating creatures. We are social animals; some bees are also social. Their interactions and communications, which make their colonial life function, have long been matters of interest; we wonder how a tiny brain can react appropriately to societal problems similar to those also faced by other social animals, such as humans." -- from The Bees of the World
