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.

Just started this post to show off the latest addition to the Troutnut family. We just couldn't call ourselves Alaskans without one of these:











And a video: http://www.youtube.com/watch?v=PAINsaQ7D30

We took her home last Friday at age 6 weeks, so she's coming up on 7 now and well on her way to being house-trained, crate-trained, and quiet enough that we can sleep through the night. She's a mix of McKenzie River Husky and Greenland Husky, and possibly 1/8th Lab. Both her parents are just 2 years old but are already very calm, sweet dogs. We got a good one!

Cool puppy pix, Jason! (And I like the name--very appropriate.)

Very cute. Is this the beginnings of a sled team? Would a native Alaskan say you're only 1/12 Alaskan so far?

It is definitely not the beginning of a sled team!

I seem to recall hearing that from one of my labmates two years ago when we both moved up. Now she has ten dogs. So you'd be right to be skeptical. However, I've seen how much work it is for her (it's an all-consuming hobby, even more than fly fishing) and I've got enough musher friends that I can get my fill of it without all the work. (It is fun!) Taiga may get to run with one of their teams a few times this winter.

Nah, it's a chum salmon, aka "dog salmon."

Cool pix. How did I miss this, Jason?

I'm not sure. I'll have to update it soon! She's much bigger now, but still very cute.
