Andrena agilissima is a bee that nests on sloped or vertical earth walls. Data from 3 years of fieldwork presented here show that this species is communal and uses the same nesting site for many years. On an earth wall on Isola d'Elba (Tuscany, Italy), covered with many bee nest entrances, we studied an aggregation of Andrena agilissima to determine if bees share entrances, if the sharing provides evidence for subterranean connections, and if bees involved in sharing show a division of labor. We marked several females coming out of the same entrance, as well as recapturing the same females using different entrances. No division of labor was observed in our observations.
