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.

Well folks, the end is near...on midnight of September 30th, four of my five favorite local trout fishing spots will be closed for the next seven months, including this one. So, hitting them hard while I still can, and fish are still biting! Though, the evening yielded only one trout, but a nice one! In addition to the two keeper perch (or are they smallmouth bass?? ;oD), I caught an annoying amount of little guys too small to eat...wondering if I should bring my minnow bucket along, and either throw the little ones into the stream below the dam (have fun competing with the brookies in that small cold stream environment guys!) or transplant them to Clark's Marsh, where they can compete with the bass and pumpkinseed...either way I want them outta there, too much competition for these beautiful brookies! The two I brought home (currently being frozen stiff) both had egg sacs in their bellies, so I took a couple of fertile females out of the population. The 12-incher put quite a bend in my rod, and I wasn't entirely disappointed to see it was that big of a perch...

WARNING to Spence: don't show these to your better half, or she might want to start fishing with me instead... ;oD

All fish except one perch took the mottled brown/grizzly #10 Woolly Bugger with black bead-chain eyes. This very same fly pattern worked well during my parents' visit back in May, accounting for nine keeper perch, a pile of little ones, and two nice (11-12") brookies (pics posted on here back then). This pattern has always done well here early in the season, and now perhaps later as well. Surface feeding was sparse and scattered, no response to either a #10 modified Joe's Hopper or a #12 White Wulff...no bugs visible except for a few sparse midges and they weren't bringing anything up but dinkers.

Hey, no one else is posting photos on here lately besides Spence and Jason (and a few odd bugs by Kurt), so somebody has to show that they're having some fishing success...

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Wooly Bugger? Looks like a Palmer KBF to me...:)

P.S. Couple of nice "smallies", eh?

Yes, their diet must be so rich in perch that they're starting to look like 'em.:)

But damn it Eric! Are you having any fun?! ;)

Don't let this alligator loose in the "redacted pond"!!! She'll clean it out. :) You can almost smell the perch and parr-marked brook trout on her breath.

Thanks Eric, glad to see someone else's fish for a change!

Spence, if one like that showed up in the Pond, I'm afraid I would suspend my catch-and-release ethic on that fish too...I'm told this pond used to grow 18-inch brookies, so anything that gets in the way of that happening again...goes in the freezer!
