The biology of Lasioglossum aeneiventre is described by Wcislo et al. (1993) based on nests excavated from the Meseta Central area of Costa Rica. These bees dig tunnel nests into the ground, ranging from 10-20 cm deep. Nests occur in aggregations. Nests are initiated at the beginning of the dry season, and may be new tunnels or re-used old nests. This species is active year round, and produces up to three broods of offspring per year. At the beginning of the dry season (January) single-female, recently initiated nests were common. Other nests from the previous season were re-activated, sometimes with one of the survivors from the previous generation. Mature nests contained up to 81cells and 14 females. Another wave of new nest initiation occurred from April to June. Offspring females could stay in their natal nest as non-reproductive workers (in which case the colony would be eusocial), or disperse to initiate their own nests, or stay in their natal nest as auxiliary queens or even replacement queens if the original queen died. Egg-to-adult development time is 35 days.
