Unidentified bug
Hi, I live near Columbus, Ohio. I saw the attached wasp looking insect on my back porch. It has a very long tail attached. I’ve never seen anything like it before. Any idea what it is?
Thanks,
Jared

Hi Jared,
You have sent in a photo of a Giant Ichneumon, Megarhyssa species. This is a harmless wasp, in your case a female. She uses that long ovipositor to lay an egg on a wood boring grub. Her young then feeds off the grub.
