Megarhyssa greenei, also known asGreene's giant ichneumonid wasp, is a species of largeichneumon wasp. It is known from theUnited States and Canada.[1]
It is very similar in appearance toMegarhyssa macrurus, but the latter species has a relatively longer ovipositor (about 2x the total body length, wheregreenei is only slightly greater than 1x), and usually has more extensive dark wing markings.M. greenei also lacks the dark striping on the face present onM. macrurus.[2]
M. greenei is a parasitoid wasp, and its host isTremex columba, a sawfly.[2] Females must find a larva of this species, and lay an egg close by or on it. The larva ofMegarhyssa devours it, itpupates under the bark of trees, and it emerges as an adult one year later.[3]
