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 had some trouble molting out of the dun stage, but I took pictures anyway.
This mayfly was collected from unknown in Wisconsin on May 18th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
