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 Pumpkinseed sunfish, Lepomis gibbosus, which I caught unexpectedly in a trout stream a year before I started this site.
This fish was collected from the Marengo River in Wisconsin on July 1st, 2003 and added to Troutnut.com by Troutnut on January 25th, 2006.
