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 spinner and a few of his friends bobbing above the river amidst a snowstorm hatch of white Ephoron flies.
This mayfly was collected from the Namekagon River in Wisconsin on August 15th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
