See text Macropis is a genus of bees in the family Melittidae.
They have a livery predominantly black; males are characterized by conspicuous yellow markings on the head, but the females show morphological adaptations related to their foraging habits of flower oils, posterior tibiae with very developed, covered with a dense velvety hairs.
Most species are oligolectic and feed on pollen and floral oils of Lysimachia spp.
After mating, the females dig a nest in the ground, ending with one or two rooms in which is collected the pollen, which is placed on the egg.
The larvae, feeding on the pollen, develop rapidly, and within 10 days turn into pupae, spending the winter in this stage.
