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.

What would you recomend as material for making a seinne to sample for bugs????

Aaron-
Just get roll of window screening material. It can be purchased at a hardware store for perhaps $5-$8.

I use wedding viel material, get it at a craft/fabric shop... they even have pink. More flexable than the window screening. Don't use aluminum screening, loose ends snag clothing, etc. The plastic window screening tends to unravel.
Drag free??? If the fly didn't drag, I wouldn't know where it was!!

Be careful if you use your wife's wedding veil not to get it dirty.
I like the idea of using something white, as Pete suggests. My seine is made from window screen, but it's black and it can be hard to see insects well on it, particularly subtle color variations. Perhaps I'll make a white one for myself.
More important than the rigidity of the screen is probably how you frame it. I have a very simple design - two upright pieces of trim (probably 1/4" x 1-1/2") that the screen is stapled to. That way, it rolls up like a scroll when not in use and still gives you a way of holding it securely when it's in the current. Make the trim just short enough that you can carry the seine in the back pocket of your vest. Mine's a little longer than I'd like - nice for keeping my hands out of frigid water while seining, but not so easy to take with me on the stream. I keep meaning to take a few inches off it, but I spend too much time on the internet to have the time to do it.

OK, I got fancy, I used 1" dowels, about 3' long

Hey thanks for the suggestions. Tight lines.

Gonzo, who is off skiing for the winter, showed me how to make a small seine with wooden or fiberglass dowels, grey plastic window screen, and duct tape. It works very well and can be rolled up and carried in a vest.

I use 1/4 inch dowels about 10 inches longwith hot melt glue.

They fasten red (crimson red) wool around a hook, and fix onto the wool two feathers which grow under a cock’s wattles, and which in colour are like wax.
