In spring, males of Anclrena erigeniae fly in swarms of thousands over woodland floors where conspecific females nest and forage for pollen and nectar from Claytonia virginica. Individually marked males, that were found from 1-11 days after marking, have overlapping home ranges that are greater than 49m. Mating attempts last from 1-178 sec; one copulation took 63 sec. Based on this study and a literature survey involving 74 Anclrena spp., males appear to patrol and mate on flowers more frequently than at other places .
