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.

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.

Just a heads up to anyone living near a Gander Mountain. If you are not already aware they are having some amazing sales on everything in the store.
Today I bought two Scientific "Master Textured Series" Nymph/Indicator lines. They list for $85 each and I paid $25 for each line. One is a #6 and the other a #7. I bought them pretty much solely to use for my Erie steelheading as I nymph at least 95% of the time with and without an indicator. The body of the line is "willow" color and a few feet of the tip is orange to "help see takes". Kind of a funny statement relative to steelheading since when a fish eats the nymph there is absolutely no doubt that a fish took the fly.
The fishing shirts are also on sale. I already own too many of those Supplex type nylon long sleeve shirts but I did buy two heavy cotton to layer for the fall trips before it gets really cold. $10.00 per shirt for the cotton and $20 for the nylon that are normally $40.

Thanks Matt, guess I may visit the Flint store only about a 20 mile drive. I remember when the orginal Flint store opened, I was on third shift and stopped on the way home, I was one the first there. It was very exciting to have a cool sporting good store so close to home. Boy things sure went down hill in a hurry.

Thanks for the heads up, Matt. Was able to get a nice nylon summer fishing shirt and nylon walking shorts at the Frisco TX store for 50% off. Although I had expected to find the inventory seriously depleted by the "Going Out Of Business" sale, that was certainly not the case.

I think that management is bringing in inventory from other stores that aren't moving it quickly enough. There was actually more clothing at my store than when I went there about three months ago after I first had heard they were closing.
