Wasp (1 of 2) (IMAGE) Rice University Caption The crypt-keeper wasp, Euderus set, is a parasite that takes advantage of another parasite, the gall wasp. It infects the maturing gall wasp in its crypt and modifies its victim's behavior, forcing the gall wasp to make its escape hole too small. E. set then escapes through the gall wasp's body and emerges to freedom through its head.
