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 a nymph that has recently molted thus has not yet acquired its normal coloration.
This stonefly was collected from the Flathead River-upper in Montana on June 15th, 2010 and added to Troutnut.com by Bnewell on June 26th, 2011.
