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.

What did your Grandmother teach you Joe ?
When I got serious about this, on the Roaring Fork, forty years ago, Chuck and Georges made a point of instructing me to find out exactly what is in the biomass at any given time, imitate it and proceed from there.
Teh Google makes that a lot easier these days... :0)
