This "specimen" is actually two different duns, one missing the middle front and back left legs, the other missing the terminal filament i.e. middle tail. I added them together by accident, but since they're the same species, stage, and gender, I might as well leave them together.

This mayfly was collected from the Big Lost River on August 2nd, 2020 and added to Troutnut.com on August 18th, 2020.
