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.

Dorsal view of a Grammotaulius betteni (Limnephilidae) (Northern Caddisfly) Caddisfly Larva from the Yakima River in Washington
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.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Hi all,
Put up some flies the other day, but no looks/ratings yet.

Hope you enjoy them!

Neat little page (this one too). Have been enjoying reading all the fly banter.

Nice flies, and good photography, too! I like the blurred jungle cock cape background on the Creamsicle fly.

Thanks Jason. I've used that effect on other shots as well. Really like how it really seems to make the fly 'pop'.

Lovely stuff, Streamertyr. Flies like the Shushan Postmaster and Chief Needabeh always evoke the "golden age" for me--a time of beautiful flies with wonderful names. It's nice to see some great traditional tying, though the Moser Parr is also nice. (I'm sure people are getting tired of looking at all of that realistic crap of mine!) :)

Thanks Lloyd. We're definitely in the 'synthetic & strip age' now, with regard to streamers. The histories of the older patterns has always attracted me to them. No doubt the 'golden age' tyers I focus on (Carrie Stevens, Lew Oatman, etc.) would have employed some of the modern materials we do today, should they have had them at their disposal. There is, however, just something about a classic featherwing or bucktail with a nice amber jungle cock eye...

Some of your realistic forage fish are wonderful, as are Roman's. I recall a couple of yours sticking out in my mind from the first time I saw your book and flipped through it in a local shop. I haven't really focused in on tying and fishing these all that much yet, but there is plenty of time.... :-)

I actually just finished posting exactly what Jason said on the Hacklehead site. Nice work, Streamertyr.
