The general part includes historical essays exploring the subfamilies, a section on the morphology of adults, generalizing essays on biological characteristics and morphology of the preimaginal stages, and a section on the geographical distribution of the subfamilies in the Palearctic. As part of a systematic classification of these subfamilies, the book includes keys to genera and species, and detailed sketches to the 12 genera and 71 species, including diagnoses, characteristics of taxa, major taxonomic literature, data on synonymy, detailed information on distribution, data on phenology and trophic relations and summarized information on biological features. The book is illustrated with black and white morphological line drawings and maps, as well as plates with colour photos of bees.
