Epeolus compactus

Cresson, 1878

Compact Cellophane-Cuckoo

Epeolus compactus is a cleptoparasitic cuckoo bee in the Apidae. It is a specialized nest of Colletes kincaidii, a ground-nesting polyester bee. The occurs in North America and Mexico. Females enter nests during the provisioning phase to lay on pollen masses, and the resulting larvae consume both the host egg and its pollen provision.

Taxonomic history

Described by Cresson in 1878. The name 'Epeolus' is thought to be a diminutive of Epeus/Epeius from Greek mythology, the soldier credited with the Trojan Horse—possibly alluding to the deceptive, infiltrating nature of these cleptoparasitic bees.
