Using emergence traps checked daily for 40 days at East Lawn Cemetery near Cornell, the team estimated a mean population size of 5.5 million emerging bees within a compact area and documented synchronized host emergence with more gradual, delayed emergence by Nomada cuckoo bees, plus low-frequency associates including a meloid beetle and a conopid fly. Danforth explains A. regularis biology and its exceptional importance and effectiveness as an apple pollinator, highlights evidence for greater female investment as a potential sign of abundant resources, and argues cemeteries and other nest sites may be overlooked conservation assets, supported by Cornell\u2019s Ground-Nesting Bees iNaturalist initiative.
