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 Epeorus pluralis dun is recently deceased in these photos. I decided not to photograph several lively, less mature nymphs. This one was ready to hatch, as indicated by the black wing pads. I believe it had not been dead long enough to lose its natural coloration.
