Macropidini
Macropidini is a tribe of bees within the family Melittidae, subfamily Melittinae. These bees are solitary and ground-nesting, with most species belonging to the genus Macropis. They are notable for their specialized oil-collecting behavior, gathering floral oils from Lysimachia (Primulaceae) flowers to provision their nests. This oil-collecting adaptation is rare among bees and represents a distinctive ecological specialization.
