Giant Ichneumon

Hi JAG,
You have been mislead.  The Giant Ichneumon, Megarhyssa atrata, is not in the true sense of the word, a wood boring insect.  This non-stinging wasp relative is a parasitic Hymenopteran.  The female, like the individual in your photo, lays her eggs in trees that have been infested by Pigeon Horntail Larvae and other wood boring insects.  The larval Giant Ichneumon feeds on the wood boring insects.
