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 specimen keys to the Epeorus albertae group of species. Of the five species in that group, the two known in Washington state are Epeorus albertae and Epeorus dulciana. Of the two, albertae has been collected in vastly more locations in Washington than dulciana, suggesting it is far more common. On that basis alone I'm tentatively putting this nymph in albertae, with the large caveat that there's no real information to rule out dulciana.
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 finally got the time to catch up on processing photos from the past month's several fishing and bug-collecting trips. Go to any of the main non-forum pages of the site (like the homepage) and scroll down the left column to the "Recent Updates" to browse through the new stuff.

Enjoy!

One of my favorite new additions is a photo sequence of an Isonychia nymph emerging along a middle stretch of the Esopus, above the portal.
