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.

We had a professional casting instructor all lined up to give us a casting clinic on Wedding Pond in Liverpool. Unfortunately, he had a loss in the family recently and was unable to attend. So I decided the show must go on. We had a small showing, but it was nice to see them there. We decided we ought to skip the pond and go straight to the trout. We headed down to Butternut Creek and found ourselves facing the wind with every cast. Luckily the students were very understanding and enthusiastic even though they were only able to wet an indicator. Dan, Woody and myself who all had licenses were able to catch fish while we taught our few eager students. We were able to catch and release a few and show them the beauty that is a brown trout. All in all I think our first off campus event was a great success. We will be back on Butternut in a few weeks doing electroshocking and stream surveys with Trout Unlimited and other organizations on the 26th.

That's OK. Tell them that sometimes even experienced fishermen do nothing more than wet an indicator. In the immortal words of Steven Wright: "There's a fine line between fishing and standing on the shore like an idiot."
I know I've crossed that line many times.
Good job with the ambassador work - keep it up.

Well Jamie sounds like you guys all had fun and your main purpose is to get more people into the sport and teaching them respect for the fish and the waters how could there be a better day than that.
IF I am not flyfishing or bird hunting I must be doing something bad like working !!
