Plateaux-Quénu (2008) reviews the social biology of this Mediterranean and central European species under the name Lasioglossum euboeensis. Lasioglossum euboeense makes nests that are burrows into the soil. The tunnel opens into a larger cavity, which contains a cluster of brood cells. Females who have mated the previous autumn and overwintered initiate nests in April of the following year. They may initiate nests solitarily or in a cofoundress group. The first brood of offspring provisioned in the spring consist of a few small males and female workers. When the workers emerge, the nests become eusocial: reproductive queen(s) and non-reproductive workers foraging for pollen and nectar and provisioning the queen’s offspring. These workers will provision a second brood of larger female future nest foundresses (who will overwinter the following winter) and males (who will mate with other future foundresses and die before winter). Both queens and workers open cells to inspect the brood in this species.
