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 is one of four specimens I photographed together from the same hatch, also including a nymph, a female dun, and a male spinner.
This mayfly was collected from Mystery Creek #304 in Idaho on July 23rd, 2022 and added to Troutnut.com by Troutnut on January 15th, 2023.
