Ichneumon wasp

The Ichneumonidae are a parasitoid wasp family within the order Hymenoptera. Insects in the family Ichneumonidae are commonly called ichneumon wasps or ichneumonids.Less exact terms are ichneumon flies (they are not closely related to true flies), or scorpion wasps due to the extreme lengthening and curving of the abdomen (scorpions are arachnids). The name is derived from Latin 'ichneumon', from Ancient Greek ἰχνεύμων (ikhneúmōn, "tracker"), from ἴχνος (íkhnos, "track, footstep"). It apparently refers to the ichneumonids' habit of searching leaves, leaf litter or the ground for hosts.
