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.

This wild-looking little thing completely puzzled me. At first I was thinking beetle or month larva, until I got a look at the pictures on the computer screen. I made a couple of incorrect guesses before entomologist Greg Courtney pointed me in the right direction with Psychodidae. He suggested a possible genus of Thornburghiella, but could not rule out some other members of the tribe Pericomini.

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.

I have fished South Mountains State Park in NC twice this month and the trout are eating a lot of something small. It's probably emergers of one or another but there are a lot of these small pale yellow flies that remind me of a fruit fly. I think they are micro caddis's but I'm not sure. I have grabed them and my best description would be pale yellow, 1 to 2 mm long (.04-.08"), a oblong stout body, with layed down caddis like wings on either side (same pale yellow color) that are twice as long as the body. when they fly they almost apear as small mayflies and fly slow. Any help would be greatly appreciated and especially any patterns to tie. The fish are feeding mainly on the surface but also under water as from time to time. Thank's
