Evylaeus comagenensis (Knerer and Atwood) (Hymenoptera: Halictidae) is a boreal carinate species with solitary to nearly unique semisocial or quasisocial behavior. In the Adirondacks of northern New York, it was at the southern limit of its range, which may be restricted by the deleterious effects of summer heat and drought on its brood. The brood was in exceptionally shallow subterranean clusters (combs) of delicate earthen cells. Its nest architecture, phenology, associates, and sociobiology are discussed.
