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.

Dorsal view of a Zapada cinctipes (Nemouridae) (Tiny Winter Black) Stonefly Nymph from the Yakima River in Washington
Nymphs of this species were fairly common in late-winter kick net samples from the upper Yakima River. Although I could not find a key to species of Zapada nymphs, a revision of the Nemouridae family by Baumann (1975) includes the following helpful sentence: "2 cervical gills on each side of midline, 1 arising inside and 1 outside of lateral cervical sclerites, usually single and elongate, sometimes constricted but with 3 or 4 branches arising beyond gill base in Zapada cinctipes." This specimen clearly has the branches and is within the range of that species.
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 only fished a couple of hours but it was fishing great. I was using a 2 fly rig, a #16 Pheasant tail, dropped with a #20 Mercury RS2. I was dead drifting through the riffles, and retreiving in the pools and tail outs, and was successful with both presentations.

That's a beautiful trout! Which fly did it take?

Thanks for posting. I've always wanted to fish Colorado. I was out there once when I was about 12 and I have a really vivid memory of watching trout swim around in the Colorado River in Rocky Mountain National Park. I had never caught a trout before at that time, but I really wanted to.

It took a #20 Mercury RS2 with 7x tippet, it is one of Pat Dorsey's creations, it is a great all around fly. I use it as my main prospecting fly. My favorite size is a #22. I caught it on the retreive about 16" under the surface, after watching some browns take emergers. I felt bad because it swallowed the fly, and it took longer than i liked to net, but I took great care in reviving it. I held on to it's tail and kept moving water past the gills for about 60 seconds. Then in a flash it was gone, I was just as happy knowing that it would be fine as I was catching it. This was the first cutthroat I have ever caught and to date the largest trout I have ever netted.
As a side note you have a great web site and I have been veiwing it for about a year and a half, it sits in my favorites and is veiwed at least once a week.
Keep up the good work, and I wish you tight lines!
