I saw this wasp next to a path in a forest preserve
Though your email indicates you do not know what this creature is, your name on the digital file indicates you identified it as an Ichneumon, a large family of parasitoid wasps. We believe, because of the noticeable spots on the wings, the coloration of the body, and the location of the sighting, that your individual is Megarhyssa greenei, one of the Giant Ichneumons. You can compare your image to photographs posted to BugGuide.
