Usually metallic green or blue, but sometimes black. Thorax is pitted, and abdomen is short and triangular.
Shares some characteristics of pteromalids with a large, colorful, and metallic bulging thorax, but differs in having deep parapsidal sutures and distinctive wing venation with long marginal and submarginal veins and a short stigma. (Comment by Ross Hill).
Usually attack the pupae of tachinids, braconids, or ichneumonids (all of them parasitoids)
Life Cycle
In some species, the egg is deposited on the foliage and the larva is of the planidium type. It mounts a member of the secondary host species, and eventually parasitizes the parasitoid of the larvae.
Most are hyperparasitoids.
Some are primary parasitoids of wood-boring beetle larvae (Anobiidae and Platypodidae) and less commonly of a few other orders.
