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.

Hmmmmm. The evolution of tying tools. An interesting concept.

When asked what I just caught that monster on I showed him. He put on his magnifiers and said, "I can't believe they can see that."

The reason the deer population is down is because the fly fisherman are killing all the deer to tie deer hair flies.

No, it's because of women drivers talking on their cell-phones!

Who are trying to locate their husbands or boyfriends who are fishing with their deer hair flies.

|"It is not uncommon to see several folks out fishing in the middle of the afternoon in the middle of the week in the middle of the winter. It use to be unheard of to see another person out fishing at these times, but not anymore."
Funny you mentioned winter fishing. For years, my brother and I would fish on Christmas day in Potter County. It hasn't happened the last few years because of schedules but we never used to see anyone on the stream. People thought we were crazy. It would definitely dull the experience if we ran into a bunch of other people. It was always a special time together, maybe the only time in a year that we had the opportunity to fish together. And the solitude was part of what made it special.
