Etymology: The name comes from ancient Egypt, via the Greek word "ichneumon," which was the Greek name for the Egyptian mongoose (Herpestes ichneumon). The Greeks reported that this small animal raided crocodile eggs buried in riverbank sand, and Aelian and Pliny repeated the story that it would enter a crocodile's open mouth and gnaw its way out from inside. The Greek word itself meant "tracker" or "one who tracks," from "ichneuein," to track or hunt out, which is why the animal bore that name. The wasps took the name because of their behaviour. Female ichneumon wasps lay their eggs inside or on other insect larvae, and the young wasps eat their hosts from within, much as the mongoose was imagined to do. Carl Linnaeus used the Latin form "Ichneumon" for a genus of these wasps in the 1750s, and the family name "Ichneumonidae" was formed from it in the 19th century by adding the standard Latin-derived family ending "-idae."
