Megarhyssa, also known as giant ichneumonid wasps, giant ichneumons, or stump stabbers,[1] is a genus of large ichneumon wasps, with some species known for having the longest ovipositors of any insects. They are idiobiont endoparasitoids of the larvae of wood-boring horntail wasps. The ovipositor can be mistaken for a large stinger.[2]
