Epeolus interruptus
Interrupted Cellophane-cuckoo Bee
Epeolus interruptus is a cleptoparasitic (cuckoo) bee in the family Apidae, native to North America. First described by Robertson in 1900, this species invades the nests of polyester bees (genus Colletes) to lay its eggs. Like other cuckoo bees, females lack the branched body hairs used for pollen collection and instead rely on host bees to provision their offspring. The species exhibits reduced pilosity compared to non-parasitic bees, giving it a wasp-like appearance.
