Possible Giant Ichneumon – Megarhyssa atrata
May 31, 2009
We found a number of these bugs on the side of a tree while walking through a forest preserve in Northern Illinois (Rockford). They didn’t seem skittish and allowed us to take quite a few hi-res photos of them. There were probably eight or so of them on a single tree. We never saw them anywhere else in the park, only on one tree.
We are trying to devote a bit of time to addressing unanswered mail, and your photo of a female Megarhyssa atrata in the act of ovipositing is beautiful.
