Lasioglossum zephyrum (Smith), a pr1m1-tively social halictine bee with poorly de-fined castes, nested in soil-filled, narrow observation boxes with glass sides in insectary rooms. The youngest females did most of the excavation of the burrows. The mandibles were used to loosen the soil, which was carried about under the thorax with the middle tarsi and packed into the burrow walls with the pygidial plate.
