Dear Concerned Mimi,
This is a harmless, beneficial Giant Ichneumon in the genus Megarhyssa, sometimes called a Stump Stabber because the female uses her lengthy ovipositor to lay her eggs in diseased and dying trees where the larvae will be able to feed on the the wood boring larvae of Horntails. We believe your individual is Megarhyssa macrurus.
