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.
I found this stonefly on some streamside vegetation. I didn't see any in the air in several hours of fishing.
This stonefly was collected from the Foss River in Washington on September 10th, 2020 and added to Troutnut.com by Troutnut on September 19th, 2020.
