Males will search for females flying over nest sites and resting on plants nearby. Once they have mated. The adult female will lay an egg in a burrow and collect pollen back for the larva to feed on once hatched. The larva will overwinter feeding and maturing. Pupation occurs early spring with emergence beginning of the summer season. These solitary bees will live independently, not depending on a colony for their survival. Adults live about 1 month. One generation occurs per year.
