Thanks for having this site, I’m a nature enthusiast and try to treat most bugs with admiration and respect. Saw this interesting bug in a hallway yesterday and was curious what kind of bug it is.

Dear AB,
This is a Giant Ichneumon in the genus Megarhyssa, and it is commonly called a Stump Stabber because the female uses her lengthy ovipositor to lay eggs beneath the bark of trees where the larvae will feed on the larvae of wood boring Horntail larvae.
