Eupelmidae

These wasps are 1.5-20 mm long and they are usually metallic. The midlegs are attached distinctly behind the midline of the mesopleuron, adjacent to the hind legs and far from the front legs. Dead individuals are often contorted into a U-shape, with head and abdomen (metasoma) reflexed upwards. Species of Anastatus are endoparasitic on the eggs of Orthoptera, Blat-taria, Hemiptera, and Lepidoptera. Eupelmus atriflagellum is an ootheca parasite ofBlattella germanica in Australia.

Eupelmid eggcase parasite, Anastatus floridanus This wasp is an ootheca parasite ofEurycotisfloridana, Periplaneta americana, and Blatta orientalis.Wasps may lay eggs in an ootheca carried by the female cockroach, or after the ootheca is deposited and is as many as 36 days old. Several A. floridanus females may lay eggs in the same ootheca. InE.floridana, developmentis completed in about 36 days at about 29 °C. Development time is regulated by the number ofparasites in the ootheca. As many as 306 adult A. floridanus may develop from one cockroach ootheca, and there are 1-6 emergence holes in parasitized E.floridana oothecae. Parthenogenesis occurs in this species, and unfertilized eggs produce males. This species is widely distributed in the USA, Europe, and Asia.

Cockroach eggcase parasite, Anastatus tenuipes This wasp is an ootheca parasite of Supella longipalpa, and perhaps Periplaneta americana. Adults may be seen running rapidly on walls and other surfaces in buildings infested with the cockroach host. The adults usually hop across surfaces; they are rarely seen flying. The female wasp begins the egg-laying process by touching the ootheca with her antennae many times, then she inserts her eggs. Developmentis completed in about32.6 days at 27.8 °C. Several females may attack the same ootheca, and 10-15 adult wasps may develop from one ootheca. Parthenogenesis occurs in this species, and unfertilized eggs produce males. It is widely distributed in the USA, Europe, and Asia.
