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 one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.
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.

Grayling & bugs on the upper Gulkana River

By Troutnut on July 16th, 2011
We went sightseeing in the Alaska Range on Sunday and made a quick stop near where the Gulkana River crosses the Denali Highway. Wader issues prevented us from venturing very far, so we were confined to a long stretch of easily accessed pocket water containing about two pockets, which held one nice grayling for each of us. Once again, Lena caught the first fish, giving my neuroscientist wife her chance to debut as a fashion model for the Troutnut store:



(Any wives reading this can buy "I outfish my husband" stuff here.)

I also collected some nymphs and a beautiful Drunella doddsii dun to photograph.

These specimens were collected from a mating swarm from the east branch of the North Fork of the Touchet River, upstream from the Bluewood Ski Area turn.It was a sunny warm day, mating swarm as 4-8 ft. above this small stream. Four male spinners were collected.Stream photos were taken.

Grayling fishing and bug collecting at Nome Creek

By Troutnut on July 9th, 2011
It's been a busy year, and this is the first time I've been out fly fishing. My wife and I drove up to Nome Creek for a couple hours, looking for some easy action on small grayling, and it did not disappoint. I was still threading the line up through my guides when I heard her calling from the stream with a grayling on her fly. I told her that since she got the first fly-caught fish of the year, she can officially wear her I outfish my husband! merchandise now.



I also collected some nymphs for the site for the first time in a few years, including several mature Ephemerella aurivillii nymphs. Our dog Taiga had not experienced kick-netting before, but she decided to try to be as helpful as she could, imitating me by walking in front of the net and pawing at the water. The collection was very successful.

This is the first time I've kicknetted bugs since we got Taiga, and she turns out to be so very helpful.
