Found in mid-Michigan in a wood pile. He was disoriented and walking in the grass, and let us move him without any issue. Looks like it has a very large stinger.

Dear Melissa,
We believe we have correctly identified this female Crane Fly as
Tanyptera dorsalis, formerly Ctenophora dorsalis, thanks to images posted to BugGuide where it states:  “larvae live in decaying wood of recently dead deciduous hardwood trees, often in prostrate trunks that are fairly sound.”  This BugGuide image illustrates the female ovipositing using her egg-laying organ that you have mistaken for a stinger.  The coloring and shape of this Crane Fly likely provides the species with some protection as it seems to mimic the markings on many stinging wasps.
