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.

Unable to post a picture here, I can "try" and tell you what the Maggot Ball fly is like!?!
Tied on a #14 scud hook.
Take 3 to 4 strands of antron white yarn,or, equivalent.1" long
Using 6/0 or 8/0 black thread, tie one end of yarn to hook.Mid shank.
On loose end, QUICKLY singe end with a lighter or match, until end melts and turns dark. (either dark brown or black, depending on type of yarn used).
That's about it,for a "Maggot Ball" fly!
Hope this helps and hope you catch fish on it! In larger sizes, this fly's been used for steelhead quite often!
