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

Dorsal view of a Grammotaulius betteni (Limnephilidae) (Northern Caddisfly) Caddisfly Larva from the Yakima River in Washington
This is a striking caddis larva with an interesting color pattern on the head. Here are some characteristics I was able to see under the microscope, but could not easily expose for a picture:
- The prosternal horn is present.
- The mandible is clearly toothed, not formed into a uniform scraper blade.
- The seems to be only 2 major setae on the ventral edge of the hind femur.
- Chloride epithelia seem to be absent from the dorsal side of any abdominal segments.
Based on these characteristics and the ones more easily visible from the pictures, this seems to be Grammotaulius. The key's description of the case is spot-on: "Case cylindrical, made of longitudinally arranged sedge or similar leaves," as is the description of the markings on the head, "Dorsum of head light brownish yellow with numerous discrete, small, dark spots." The spot pattern on the head is a very good match to figure 19.312 of Merritt R.W., Cummins, K.W., and Berg, M.B. (2019). The species ID is based on Grammotaulius betteni being the only species of this genus known in Washington state.
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.

Many 8# - 10# fish and most were very bright. Best flies were #12 - #16 stoneflies in black and brown with 4X tippet. 3X works but you get more hookups with 4X.

Nice fish, Matt! I hope to go up during Christmas break.

Hello Louis,

If you are going up at Christmas break maybe we can go together. Remember though it is pointless to drive for six hours if the streams are low. Even when there are fish in the creeks they are very spooky when the creeks are low and clear. They see guys walking around all day and are jumpy. When they are low normally you can hook a few at dawn and then again at dusk.

Ideally you will be keeping an eye on the weather - you don't want just a shower because by the time you get there the creeks will be low again. You want a good all day, or two day steady rain, then check out the reports at fisherie.com - when it stops you should be driving up. As the creeks start to drop and turn a greenish color with little visibility is when you will get fish.

I used a 9' #7 and thought about using a 9' #6 as you aren't casting very much at all - a roll cast is pretty much all I did and I never used more than two BB's but the power and size of the fish made me happy I was using the #7. The stream beds are just full of shale - you will lose gobs of flies - if you aren't losing flies you probably aren't down in the zone.

If you look behind me at the top picture you can see light and dark water - the edge between the light and dark is a shelf and fish lay in the darker colored water and parallel to those shelves.

Thanks CaseyP
I should be able to post a pic, but as you see I'm not doing a very good job

They fasten red (crimson red) wool around a hook, and fix onto the wool two feathers which grow under a cock’s wattles, and which in colour are like wax.

I think I figured it out.
