Females of Lasioglossum (Chilalictus) species. In each species, patches of whitish tomentum form bands or spots at the bases of abdominal terga. (a) L. (C.) mediopolitum. A female approaches a nest entrance in soil, its hind leg scopae loaded with pollen. Just the tip of an antenna visible inside the entrance reveals the presence of another female, possibly a guard. Photo: Jean and Fred Hort. (b) L. (C.) bicingulatum. The distinctive appearance of this species is produced by the abdominal terga having both basal bands of whitish tomentum and translucent brown hind margins. Photo: marc newman. (c) L. (C.) mirandum.
