Fig. 1.

A snapshot of the diversity of bees. Bees are taxonomically classified under the insect Order Hymenoptera, along with ants, wasps and sawflies, and are part of the superfamily Apoidea, and clade Anthophila, with seven recognised families. Although only 50 of the ~ 20 000 described bee species are actively managed by people, the entire clade is important for ecosystem functioning and human well-being. Bees and flowering plants have co-evolved, making bees effective pollinators of a large proportion of flowering plant species. There are perhaps a further ~ 5 000 bee species that are yet to be described. Data source: Ascher and Pickering (2014).
