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

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.
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'm a retired National Park Ranger that is now rediscovering fly fishing. I was an avid fly fisherman from the time I was 8 until I got out of high school. Then work and raising a family took over and I moved away from trout streams.

Now that I'm retired I'm rediscovering the joy and grace of trout fishing. I'm hoping to start tying my own flies and I've finally located a local group of folks who seem willing to indulge a lot of questions.

I look forward to learning from all of you and hopefully being able to share as well as I progress in this wonderful hobby!
Tight Lines,

Hey, it's good to see another Missouri trout fisherman on here! If you're in Richland, I'd just bet we fish quite a few of the same streams. I do quite a bit of of my trout fishing in the spring creeks not too far from there, around Rolla.

I'll be looking forward to your posts!

Welcome. We are a pretty diverse lot here and never short of opinions, but willing to share...

The help of your local group will get you back to speed and maybe we can fill in any gaps.

Its a great pastime this obsession of ours. Welcome back!
