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.

My then-girlfriend, now-wife took this picture with my camera.

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.

Megaleuctra stigmata (Leuctridae) (Little Black Needlefly) Stonefly Adult from Talking Water Creek in Montana

This is one of rarest stoneflies in western Montana. It is a bit unusual that it is fairly abundant in a handful of streams that empty into the east side of Flathead Lake. A very beautiful bug.
