On my way back from my daily run at the local hiking trail and this scary looking thing stuck to my windshield and didn’t move for quarter of a mile. I had to take a picture of it while driving but I was careful. But look at the stinger! I’ve never seen a mosquito quite like that.
This is sept. 6th in southwestern ohio

Dear Nathan,
This is NOT a Mosquito.  It is a parasitic Giant Ichneumon wasp 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 that are infested with wood boring larvae of Horntails, including the Pigeon Horntail.
