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.

Belostoma flumineum (Electric Light Bug) Giant Water Bug Adult Pictures

I haven't seen the imitation of these things stressed, but in August 2003 on one of my favorite rivers the largest brown trout I kept had stomachs full of these things.

This giant water bug was collected from the Namekagon River in Wisconsin on January 13th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.

Just a thought...perhaps a "cow dung" traditional wet fly would cover this bug. As for the green sheen on the wing, one might use slips from green wing teal secondary wing feathers.
