All members of the Leucospididae are primary parasites of aculeate Hymenoptera, developing
on the fully grown larvae or pupae. The adult female drills through the cell wall of the host with
her lengthy ovipositor, and also through the cocoon inside the cell if there is one, and deposits
her egg inside. This egg is suspended by a slender stalk. When the egg hatches, the active larva
searches out its host, attaches to it, and feeds at various places on its body. Later instars are
more quiescent. Pupation occurs inside the cell of the host, and the adult uses its mandibles to
break an opening to the outside. The adults often are taken by sweeping flowers, because they
feed on pollen. They tend to resemble their hosts in body form and color.
