The biology of Lasioglossum figueresi is described by Wcislo et al. (1993) based on nests excavated from the Meseta Central area of Costa Rica. This species digs tunnel nests into earthen banks; tunnels ranged from 12-17 cm deep. Nests are usually aggregated, but may occur singly as well. Brood cells containing offspring are attached directly to the tunnel. Nests occur in aggregations. Most nests (80-90%) are solitary, with only one female foraging and provisioning cells with pollen and nectar. Social nests contain two or three females, which may have reproductive division of labor (only one female with developed ovaries), or may have multiple females with developed ovaries. Midway through the dry season females stop provisioning their nests, and remain inside. The foundress females die before their offspring emerge as adults in April and May. Offspring development time, 80 days, is longer than other halictine bees. These offspring remain in the nest until mid-June, when they emerge to mate. Newly mated females either initiate new nests or re-use old nests for their own reproduction. Bees used pollen from Melampodium divaricatum (Asteraceae) and Croton bilbergianus (Euphorbiaceae). The bees were parasitized by the phorid fly Phalacrotophora halictorum.
