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

Case view of a Pycnopsyche guttifera (Limnephilidae) (Great Autumn Brown Sedge) Caddisfly Larva from the Yakima River in Washington
It's only barely visible in one of my pictures, but I confirmed under the microscope that this one has a prosternal horn and the antennae are mid-way between the eyes and front of the head capsule.

I'm calling this one Pycnopsyche, but it's a bit perplexing. It seems to key definitively to at least Couplet 8 of the Key to Genera of Limnephilidae Larvae. That narrows it down to three genera, and the case seems wrong for the other two. The case looks right for Pycnopsyche, and it fits one of the key characteristics: "Abdominal sternum II without chloride epithelium and abdominal segment IX with only single seta on each side of dorsal sclerite." However, the characteristic "metanotal sa1 sclerites not fused, although often contiguous" does not seem to fit well. Those sclerites sure look fused to me, although I can make out a thin groove in the touching halves in the anterior half under the microscope. Perhaps this is a regional variation.

The only species of Pycnopsyche documented in Washington state is Pycnopsyche guttifera, and the colors and markings around the head of this specimen seem to match very well a specimen of that species from Massachusetts on Bugguide. So I am placing it in that species for now.

Whatever species this is, I photographed another specimen of seemingly the same species from the same spot a couple months later.
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.

These are both May browns and both pictures were taken by Tony, but the first one is 2011 and the second was caught last week. I thought of trying to pull ur legs by saying I shaved the goatee off but you all know I never tell a lie.

So long as you have the pictures to prove it Matt!

Beautiful fish, Matt. The black spotted variety of brown is something we don't see a lot of in local streams. I've been told that they are either Loch Levan or Seforellen strains.

Beautiful fish Matt!!
Glad to see you have sufficient water for the boat to be of use.
Hopefully we return to more typical rainfall patterns and keep a decent head of cold water thru the summer months.

I have honed my skills to such a high level that I can target the less common black spotted variety and leave those garishly colored showboats to lesser anglers :)

Nor would we have, perhaps - the ultimate clash of fishing egos!

Uh, that would be me...
