The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.
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.

Greetings, I have a question for someone I found this one on my screen door last night and I have searched to try and come up with a name to put with it. I have tied flies for a few years but I've just duplicated patterns found in books or fly shops. I've never tried to identify the insects I have been tying, until now. By the way this mayfly is from Mid Missouri.

My guess is an Epeorus spinner. It is somewhat difficult to tell because some of the essential keys are missing. :-)

(Keys - I mean like number of tails.)

I believe there were 2 tails - right before my 3 year old needed to hold him...
