Ichneumon Wasps Ichneumonidae

The family Ichneumonidae includes more than 3,300 species in North America. It’s one of the largest insect families. Ichneumons vary widely, though they tend to have very long antennae and often long ovipositors.

Most ichneumon larvae develop on a single host and eventually kill the host, making ichneumons parasitoids, rather than parasites.

Two characteristics of Ichneumons are the “horsehead” cell in the forewing (4, 5, filled with color) and the thee ocelli on the head (6).
