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.

I just thought that it would be interesting now that it is finally over (I fished penns,spruce and little J this weekend so I can officially call it over) in central pa to hear everyone's thoughts on the months events. I personally may have caught more fish in the month of june than I have in some years. My pattern was pretty simple tmc 8089 hook, rust orange antron body, black foam over back, copper and pearl flash for wings. The best part may have been fishing for an entire month w/o a vest or even a fly box. I would show up w/ a 1/2 dozen flys stuck to my wader straps and a spool of 1x. W/O question the most fun I've ever had with a dry fly. Although I must say today did produce similar results w/a stimulator and crane fly larva.

I share the same feelings, I told Louis it took me 55 years but I finally got even with those Trout :)

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.

I also experienced the cicada hatch on the little junitata. I was fortunate enough to witness friends catch several fish in the 18 plus inch range with a pattern similair to yours. with the highlight being a 21 inch rainbow caught in the gorge by my cousin.(is it just me or do the few rainbows in the little j seem to love these cicada's even more than the browns?)

it's going to be a very long time before this tyro forgets those monster fish. and the big splashy strikes. and the big, easily removed hooks. perhaps it is a good thing that cicadas only come every 17 years, but i feel like the kid whose mother said that if Christmas came every month we'd not appreciate it half as much.

Ditto to the remarks above. I had a blast. Next up on my plate is Trico fishing. What a switch!

I, too, had a great time fishing the cicadas. It certainly brought up the big fish, although my biggest catch was a 16-incher. I missed some big ones and broke a few off before I realized 3x wasn't going to cut it. I saw a few landed in the 20 inch and over range. My biggest thrill was watching my buddy's wife hook and land fish. She had a blast we enjoyed every moment of it.

Although I missed out on the cicada hatch that everyone up north got to enjoy, the hatch sounds like a book I read last semester, The Snowfly, its a great book to read. Its a fiction book but I think some of you may like it. I wish I could remember the author, sorry.

Those not in PA may wish to look on some of the cicada websites. The hatch may be in your neck of the woods in a coming year, and it's certainly worth a bit of travel.

Fairly new to trout fishing having caught my first "stockie" on opening day in 2007 but now Im addicted and have been putting in some serious steam time and chasing natives. anyway we got up to the Little J at the end of June and I had a great time. First day out we were skunked fishing above the quarry (some smallies though). Some local at our campsite turned us on to another fishery with plenty of cold water feeders and we spent the next two days fishing there. IM not sure if the fact that the river didnt see near as much pressure as the Little J or the stars were better aligned, but I was rather pleased with landing 9 nice fish on the second day all over 15" with the largest being an 18" brown. After lunch and a fall down the rock embankment the fish were much harder to get either because the overcast melted away or we put them down. We didnt move much and probably could have went in search of more "virgin water", but being new to the area felt we had a good spot.
A limted 1 1/2 hr in the morning of the third day before our 4 hour ride home yielded a couple more nice rainbows.

Best dry fly experience to date and all caught on my own flys.
