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.

Could I get some opinions, please. I think someone mentioned it in a thread.

I have been using Veevus since it first became available here in the U.S., about 2 1/2 years ago - mostly in 10/0, 12/0, 14/0 and 16/0. It is extremely strong but does not lay flat like Tiemco 16/0 - which is no longer being distributed. I also use Semperfli Nano Silk in several different sizes.It is a gel-spun thread that lays very flat, is stronger than Veevus (it will cut right through deer and elk hair) and is expensive...

I really don't have any problems with the thousand and one other brands I own. :)
It is the brand of the month. Next year there will be a Yak/polyester blend harvested from a rare breed of Yak that lives on the Mongolian Plateau that is incredibly strong and so thin you can't actually see it. ;)
I'll be first in line with the rest of us wacko's!

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

I like the Veevus 14/0 and 16/0 for parachutes as I tie off underneath the hackles on the post, and the thin diameter allows for very little build up while the strength keeps me from breaking the thread when applying pressure to tighten the whip finish. Just bought some Semperfli, and will try it for parachutes soon, though gel spun threads can be slippery and this may require an extra wrap or two on the whip finish. I also like the Veevus for tiny flies such as Tricos or midges. For other flies I use whatever I have that seems to fit the bill, mostly Uni-thread.

Run the tip end of the gel spun thread through some wax before tying it on the hook shank - it won't slip...
