Andrena regularis
Regular Mining Bee, Regular Miner
Andrena regularis is a ground-nesting solitary mining bee native to North America. It is known to form large nesting aggregations, as documented at East Lawn Cemetery in Ithaca, New York, where it was the dominant species in a study collecting 3,251 individuals across 16 bee, fly, and beetle species. The species exhibits a 41-day emergence period from late March through mid-May, with distinct timing of male and female emergence. It serves as a host for the brood parasite Nomada imbricata. Cemeteries may function as important refugia for this and other ground-nesting bee populations.
