Polylectic, that is larvae feed on wide variety of pollens.
Life Cycle
The cut leaves from these bees serve as protective plugs within the underground nests.(4)
Most nest in pre-existent holes in wood. Female typically cuts neat, more-or-less round pieces out of leaves to serve as separators between cells of nest:
Remarks
The males of most species have enlarged light-colored front legs with a fringe of hairs and with odor glands. They use these features during mating. They partially cover the female's eyes with the hairy legs and the odor glands are placed close to the female's antennae. These adaptations resemble those of some carpenter bees and sphecid wasps.
