The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.

Our beautiful stable weather continues, so today I headed out to the Rifle with the intention of getting up into a tributary with lots of meadows for hopper fishing. Well, I had already released five trout by the time I reached the mouth of the trib! Figuring that the middle of the day wasn't going to produce much on the mainstem of the Rifle, I had planned to fish through it fairly quickly so I could get some time in the trib. No flies on the water during the afternoon, so what should I tie on? Well, how about a hopper just for the heck of it, a #10 modified Joe's Hopper again that I had stuck in my fishing hat. I had never thought of the Rifle at this location as being good hopper fishing, as it is pretty much all forested. However, I realized that there is a section where there is a pretty good stretch of grass and goldenrods on the left bank, so maybe...two little 8" browns took it first, then up near the grassy bank an 11" rainbow hit and went airborne! Further upstream, in not particularly deep water or near any significant cover, what looked like a little guy just sipped it off the surface. Setting the hook, I realized it wasn't so little after all, in fact I swear the fish grew as I was fighting him because he ended up being 15" in the net! Then another enthusiastic 9" rainbow and I was up into the trib.

Well, there used to be some nice beaver ponds in this little stream, about 14 years ago or so, but the last time I went in about 4 years ago there were none to be seen. Obviously taken out by humans, who always seem to argue that beaver ponds warm the water, block fish migration, etc....I suppose I can see the point here, as this creek has extensive gravel beds perfect for spawning (and it closes Wednesday night at midnight for the next 7 months). But without the ponds it's tough fishing, in many places just a tunnel of alders that always seem to brush over the deepest spots. In one good hole a little rainbow took it, and another slashed at it pretty good, but it was hard to find good fly casting room. As I hiked further upstream lo and behold, two beaver dams!! Oh boy, here's where they're gonna be and I can even cast to them! The first pond yielded nothing, and the second was frustrating at first, even tried a Woolly Bugger and a KBF but no sign of fishies. Wading further up, it started getting close to the top of my waders so I had to sort of throw around the bend, and then KBAM, a 12" brown takes it! After that I was pretty much done, wading up the beaver ponds had murked up the little creek pretty good on the way back down, and the Rifle was quiet with a few Nectopsyche but nothing really feeding.

And I thought my major action was going to be in the evening! The five I took on the Rifle were all before 5 p.m. with bright sunshine...it's been a helluva week of fishing: 8 brookies, 13 perch, 4 browns and three rainbows! My "end-of-the-season-is-near" frenzy continues this weekend on the Pine...and this stretch of the Rifle is open year-round! I hope our weather continues!

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

Good fishing. Thanks for the photos. That buttery brown was especially pretty.

Nice Jonathon! I finally have some New England Asters growing on the edge of my backyard...I think they are one of the few natives we still have here.

Next summer when you are visiting the folks you should make a trip with them over to Indian Springs Park just north of M59. They are managing the place with controlled burns etc, and trying to reestablish native Michigan prairie plants.

It is very interesting there. They have a side garden with the natives that are marked so you know what they are.

This early Fall season is nice. No humidity, sunny, and not too hot.

Went down to Erie Metro park yesterday to see if we could spot any migrating hawks...Wanted to get my 83 year old stepfather out of the house...There are some guys down there working with the DNR keeping track of the migrants...I missed some serious "kettles" of Broad-winged Hawks that had gone through a week or so ago. Had a Black Vulture fly over, but I was unable to make out any identification marks to make my own call, so it doesn't count. :(

Enjoy the rest of the Fall!

Nice! I may be up there this October. Hopefully I can have a somewhat similar day on the rifle as well!
