This solitary bee is a generalist pollinator and widespread in North America. It is chiefly active in April and May. Adults feed on nectar and males can be found throughout the active season, feeding and patrolling flowers in search of mates. Females feed on nectar and, toward the end of May, begin to collect pollen to provision their nests. A burrow is constructed by a single female and generally contains 5-8 cells, from 15-25 cm deep, each housing one of her offspring and a pellet of pollen. (Schrader and LaBerge, 1978)
This species is an important native pollinator of blueberries. (Adamson, 2011)
