I see I posted 2x here. For some reason I thought my original post did not go through when I didn't see it on the forum page, but it had posted down lower on the page. Sorry for the double post!

It's an ichneumon wasp, genus Megarhyssa. Parasitic on other woodboring larvae, such as Tremex, a large horntail wasp. Completely harmless to people. It uses the long ovipositor to lay eggs down in the tunnels of the woodboring wasp larvae, which then become food for the Megarhyssa larvae. Ain't bugs great? The link below has good pics of a different, but similar species.

You may find them fascinating, but I despise them! They are known parasitizers of my butterfly and moth larvae. Yuck! I know, I know, it's nature at its finest, but I still don't like them.
