Subject: Michigan Upper Peninsula
Location: Steuben, MI
July 4, 2017 3:19 pmWe were fishing in the Western Hiawatha National Forest in Michigan’s Upper Peninsula and found several exoskeletons of this bug. We found almost all of them on cedar trees near the edges of freshwater lakes. We found the in Late June. We didn’t see any live bugs. I’m in my late 30s and have lived in Michigan my whole life and have never seen this bug before. I took a photo of one husk next to a quarter. It is attached. Any ideas?

Dear Mich. Fisherman,
This is the exuvia or cast off exoskeleton of a Dragonfly. Its shape is similar to that of a Dragonhunter nymph, so we believe the species is Hagenius brevistylus. The aquatic nymphs of Dragonflies, known as naiads, leave the water and molt for the final time, emerging as winged adults.
