Family Apidae > Genus Anthophora
Anthophora
Digger Bees
In Minnesota, there are three described species within the genus Anthophora. Two of these species, Anthophora bomboides and Anthophora walshii, nest in the ground; the third species, Anthophora terminalis, nests in wood. All three species have solitary nests. Anthophora are medium-sized, robustly shaped with broad abdomens, and are fast zippy flyers. Prior to landing on the flower, both males and females often hover in front of flowers with their tongues extended outward.
Anthophora males have a brightly colored (light yellow or yellow) clypeus, and females have a black head and clypeus. Bees in this genus have three forewing submarginal cells and a short jugal lobe. Females have simple (not feathery) scopal (pollen-collecting) hairs on their hind leg tibia and basitarsus. The scopal hairs are longer on the tibiae than the basitarsus. Anthophora range in length from 10 to 16 mm (0.4 to 0.6 inches).
