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.

Does any one know much about this stream, I fished it once about 9 years ago but it was a brief visit. I was hoping some one could pass some info on spring hatches, and maybe an area that is worth seeing. (upper, lower, or middle will suffice I don't expect any one to broadcast a favorite hole).
Thanks

Yes.
(Just not me.)
I'll let the people who know the stream speak up if they want to.

Jeff, I'll PM you some information. It's easily accessible as a road goes along it. Tough stream at times!

I'll give you a tip when the fishing gets tough there:
CheezWiz and tiny treblehooks.
Fished dry.

When I found the skull in the woods, the first thing I did was call the police. But then I got curious about it. I picked it up, and started wondering who this person was, and why he had deer horns. - Jack Handey

Jeff,
You wanna fish I'll hit the water there with you.
Some free advice to any and all who want it (call it kiss and tell if you like):
If she is running bank full break out the nymphs.
Consider her a small version of Penns and about a week behind bug wise.
Watch the skinny water as you might be surprised at what lives there.
Look outside the regs in the "non-blueribbon" water.
Watch out for buzzbirds they are might thick in those parts.

Good tips, John. I'll never fault you for general info. like this, even on a widely viewed board. Perhaps you, Jeff, and I should plan a trip in the coming weeks. It'd be great to fish with the both of you. --Louis

They fasten red (crimson red) wool around a hook, and fix onto the wool two feathers which grow under a cock’s wattles, and which in colour are like wax.

Louis,
John D,
Jeff,
Name the time and place once mid april hits my wife becomes pretty lienient as long as the grass is cut and the garbage goes out to the curb.
I have to say that Penns and BFC are probably my two favorite PA streams on the grounds of setting. The fishing is often a bonus.
Good company can only enhance the outing.
