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 ia a very tiny (hook size 22-24) dun. The pictures are terrible, but it's very fragile and it's one of the first adult mayflies I ever photographed.
This mayfly was collected from unknown in Wisconsin on April 30th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
