ICHNEUMON FLY   2 comments


DEFINITION: any of a large family (Ichneumonidae) of hymenopteran insects whose larvae live as parasites in or on other insect larvae Also ichneumon wasp.

The graceful, four-winged ichneumon fly is not truly a fly. The insect is a relative of wasps, ants, and bees. The female lays her eggs on or near the eggs, larvae, and pupae of harmful insects. The ichneumon larvae that hatch from the eggs feed on the other larvae and pupae and kill them.

Ichneumon flies vary in size, but all have long, slender abdomens with long legs that trail gracefully as the insect flies through the air. From the abdomen of the female extends a threadlike egg-laying organ called an ovipositor (egg depositor).

These insects belong to the family Ichneumonidae of the order Hymenoptera. More than 3,300 species in the family Ichneumonidae have been described. Specimens from the genus Megarhyssa can measure 10 inches (25 centimetres) in length.
