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.

Superb photos, as usual. Last year I wanted to tie some nymphs for the Green Drake hatch, and didn't find any photos that gave this kind of detail.

Thanks Paul and Louis.
Louis, you better get tying. they are about to pop. As you can see this is a male and is about 23mm. The females I have collected are 3-5 mm larger.

Louis, I'd like to see your solution for the dorsal gills.

OK, but it's going to cost you some of those diamonds.

Nice Eric. Our version here should get going any day, especially since we are warming up into the 80's this week.

In terms of the gills etc, you should look up Bear Andrews' Hex. The after-shaft feather from the pheasant works.

You ever seen Shane Stalcups Green Drake Emerger? Check out Cravens site or "Tying Emergers" from the same guys that did the "Tyer's Benchside Guide".

So where's the green? :)Looks tan to me. That whole family looks that way. Blends in with their sandy/silt bottom where they live.

That Carmel color is interesting. Hard to duplicate.

Thanks Spence. I have seen a bunch of solutions, I was just curious if Louis had his own. I know what I do too ;) Actually if you look at the wingpads you can see a little green. Oh and for a nominal fee I can give you a recipe for that carmel color. and if any of you PA boys are paying attention they are going now...i will breaking in the new fishing vehicle and suffering from lack of sleep for the next couple weeks...

If you hear a storm coming through the mountains...Run!...Don't walk to this new vehicle of yours. If its any taller than the last one you'll be sleeping in the woods. ;)

You know Spence the new one is a couple inches taller. And that white pine across the road came immediately to mind when they were parked next to one another. But there is more room for a chainsaw in the new one...

I ran into one of the younger guides at a local beer store, the last time up to Grayling. His truck wouldn't start so I gave him a jump, actually Mike gave him the jump. I was teasing him because he actually had jumper cables, a small chainsaw, and a gas powered generator in his truck. What one needs up that way to cover your ass.

Turned out the truck needed an alternator. When one of the boys has a downed vehicle, everyone else has to chip in to help him out. The clients still need to float the river and they can't afford not to work.
