Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

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.

A few years ago, a downturn in good fortune forced me to sell off my expensive bamboo rods. No real biggie, in the grand scheme of things. But all season, I've been fishing my old 8' 4-wt Orvis Superfine, a four-piece, a rod I've had over a decade. It's a great rod, with loads of feel. But I noticed this season problems with the ferrules twisting. I rubbed some paraffin on the ferrules in the hope of making them stick, but it didn't help. Finally, I just took a piece of cloth and some mild soap and cleaned the the outside and inside of the ferrules. It worked; the rod is back in shape and casting wonderfully. I thought I'd "worn" out the ferrules, but they only needed cleaning. Sometimes the solution to a problem can be solved with a wee bit of logic.

cleaning them with "soapy" water is key. It is kind of like cleaning your golf club grips with soapy water it makes them tacky, where if you clean them with just water it isn't the same. I doubt if your ferrules where tacky when you got done but your getting the same effect.
I have seen nothing more beautiful than the sunrise on a cold stream.
