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.

For how many years, I wonder, have these huge slabs of rock sheltered wild brook trout?

This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.

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.

This female is probably P. heteronea or P. memorialis since these are the two species collected during the last two weeks. It is interesting that the females are this very dark brown color while the males are lighter in color.

This mayfly was collected from the Touchet River in Washington on June 29th, 2011 and added to Troutnut.com by Bnewell on June 29th, 2011.
