The life cycle of most solitary bees fits into a regular pattern. Females make nests using leaves, soil, or mud, and provision them with honey and pollen. They lay single eggs in divided cells. The eggs hatch and the larvae eat, grow, and pupate inside the same cell. The adults remain in the nest until spring or summer. The males usually emerge before the females, which are mated immediately after emergence from the nest. The cycle then repeats itself.
