Hey, this guy landed next to me here at Yakima Training Center and was wondering if you could ID it for me. Closest thing i could find was a grasshopper hunter wasp, but it doesnt look right. Thanks a bunch!

Dear Chance,
We are relatively certain that this is a Horntail in the family Siricidae which is pictured on BugGuide, but we are not sure about the species.  What appears to be a stinger is actually the ovipositor of the female, and she uses that organ to lay her eggs.  Eggs are laid beneath the surface of the bark of trees, and the larvae are wood boring insects.
