Chalepogenus

Genus of bees

The genus Chalepogenus, consisting of 21 species of solitary oil-collecting apid bees, demonstrates oligolecty by foraging on oil-producing flowers from the families Calceolariaceae, Iridaceae and Solanaceae. These oil-flowers are abundant in South America, where Chalepogenus is endemic. In contrast to honey bees, Chalepogenus species do not collect nectar; instead, they gather floral oil for various purposes, including provisioning their larvae, constructing nests, and sustaining foraging adult bees. Although oil collection has been reported to be performed by females only, both males and females have specialised oil-collecting structures.
