Lasioglossum (Dialictus) asteris is a socially parasitic bee that invades nests of Lasioglossum (Dialictus) imitatum (Smith). Upon gaining entry to the host nest, a female L. asteris dominates the host queen and forces the host worker bees to rear its offspring. The host queen tends to cache pollen and nectar and lay its eggs over this stored food. Parasitic larvae kill the host larvae in order to gain access to the food. (Wcislo 1997)
