Check out the long tail on this. The entire critter is sbout 7 inches long. I spotted it in early August in Colchester, Connecticut on a maple tree.
What you are calling a tail is actually the ovipositor that this parasitoid female Giant Ichneumon, Megarhyssa macrurus, commonly called a Stump Stabber, uses to lay her eggs beneath the bark of trees that are infested by the host insect, the wood boring larvae of Wood Wasps like the Pigeon Horntail.
Thanks for the identification of the Megarhyssa macrurus. That’s some bug!
Since I began building a naturalized permaculture forest of fruit trees and companion plants I have been taking more time to observe insects. What an amazing world.
