Giant Ichneumon

Dear M. Temple,
Many people are shocked or frightened when they encounter a Giant Ichneumon, Megarhyssa atrata, for the first time.  The Giant Ichneumon is a parasitoid insect that preys upon the wood boring larvae of another non-stinging wasp relative, the Pigeon Horntail.  A female Giant Ichneumon, like the one in your photo, locates a wood boring Horntail larva and then drills into the stump or trunk with her five inch ovipositor.  Male Giant Ichneumons do not have an ovipositor.
