Nests are located in hollow twigs, other natural cavities, holes in buildings and occasionally in the ground. Cells are provisioned by adults with nectar and pollen collected from flowers. Artificial nesting sites can be made by drilling holes of the appropriate size in boards, or by using bundles of large soda straws. Nests made in walls of buildings can be a nuisance and cause ninor structural damage. They are important pollinators of plants.
Females are capable of stinging.
