Blue-winged Olives

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.

I took some little clips of a typical afternoon for Brook Trout. Only had a few hours before work, but did pretty well.

Brookies are the best!!! I just got back from some kayak/pond fishing for them myself this evening. Biggest one tonight was 10", but this pond has thrown me foot-plus brookies before. Fished a #12 tan elkhair caddis and then a #12 Royal Wulff, they tore both of them up...

Nice little video there, James! Sooner or later I will come visit you. Right now I am actually planning a trip to Isle Royale for Labor Day Weekend! Won't get to hit the brookie fishing there though, not enough time to reach those waters. I will be taking the 8-weight along for pike...

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Wow that was nice! Didn't see much of a trail on your way in; do you use a GPS or do you just "know the way"?

@ Jonathon... I love EHC for Brookies. That's the pond you were talking about before I'm sure.

A trip up here would be worth it. Isle Royale is gorgeous. I hope you have a good time. What kind of streamers are you planning on using for those "alligators?"

@ Adirman... I have been fishing that river since I was 7. It's a REALLY long hike on some 2 track roads, then it's all poplar forest to the river. I can fish it in many different areas and I know the way by heart.

I actually caught a 14" (in the video) and one 12" and a few others around 10 or 11" not in the video. I was in the mood to film some stuff. When I got home I realized I might be able to put enough together for a short clip.

I'm no Spielberg or anything, but it's ok.
