Скачать или смотреть Ichneumonidae : Hyposoter ebeninus parasitizes Euchloe crameri

The rather specialised Hyposoter ebeninus (Gravenhorst, 1829) parasitizes young caterpillars of butterflies belonging to the tribe Anthocharini and Pierini of the family Pieridae.

This wasp of about 8 mm, parasitizes young caterpillars of the Western Dappled White. Using its ovipositor, it injects a single egg in its victim. The parasitoid larva develops inside its host (endoparasitoid) where it lives off the haemolymph, without preventing the host's growth. When the instar 3 caterpillar becomes about 11 mm, the parasitoid larva kills the host and mummifies the caterpillar by spinning a cocoon inside the body of the caterpillar in which the metamorphosis takes place. The mummified caterpillar looks like a bird dropping from which, after about 10 days, an adult wasp gnaws an exit hole, to free itself.
