The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.

A couple years back we had someone post a video here of a mayfly hatching. I think it was from Europe and was E danica and they followed it closely as it progressed downstream with its shuck hanging off the back end...Does anyone remember it, and maybe how I can find it?
