Hex Mayflies
Hexagenia limbata

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.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Male Baetidae (Blue-Winged Olive) Mayfly Dun Pictures

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.
