Females hunt bees to provision their carnivorous larvae, while adults sip nectar from flowers; they build nests in sandy soils of coastal or deciduous forest areas in the Midwest and western Appalachians. They produce two generations each year, starting nest building in early June and completing it by early July, after which the females die after about three weeks of egg-laying.
