Your letter to the bugman: My friend took this pic and because she knows my love of all things “bug” asked if I could find out anything about it. Been doing some poking around and the closest I could find was family Ichneunonidae Megarhyssa nortoni. It’s quite striking in coloration. Just wanted to share because I haven’t found a photo anywhere that matches

This is definitely a member of the superfamily Ichneumonoidea that includes the family Braconidae as well as the Ichneumon, and we believe this might be a Braconid, possibly in the genus Atanycolus that is represented on BugGuide. A definitive identification might not be possible as this is a huge superfamily with many unidentified members. According to BugGuide: “Next to impossible to identify this genus from images alone, however it is one of the more common genera in the subfamily. Identification of images on this guide page are NOT absolute! “
