Stump Stabber

Dear Sue,
This is indeed a Giant Ichneumon, probably
Megarhyssa macrurus, and Giant Ichneumons are frequently called Stump Stabbers because the female uses her very long ovipositor to lay eggs in dead and dying wood that is infested with wood boring larvae of the Pigeon Horntail, a species upon which the Stump Stabbers prey.

Thank you so much !
