Grammotaulius betteni (Northern Caddisfly) Caddisfly Larva Grammotaulius betteni (Northern Caddisfly) Caddisfly Larva

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.

This Olympus is on sale at Staples for $99. With it you get a free Cannon Photo Printer with rebates. What do you knowledgeable guys think of this for fishing and outdoor purposes? Need opinions. They also have Cannon Powershots and Kodak EasyShare cameras on sale for $135 to $180.I'm going out west next year and I'm in the market.

I was recently in the market for a camera, and after a lot of research, I wound up going with a Canon Powershot A590IS. For the money (retails for $150, I got it for $115 from Amazon), it's quite a little camera. The picture quality is great, and it has some manual functions which allow me to do some amateur photography things I've been missing since high school. I would think with Black Friday, you might be able to get it in the sub-$100 realm.

It is not waterproof, so I bought a dry bag from Aquapac. A note about the Aquapac: you can take decent photos with the camera in the dry bag, but as may be obvious, the picture gets washed out with the flash on. So, why not buy a Zip-Lock bag? The Aquapac is guaranteed for three years.
