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.

Thanks for the tip, Casey. I was just thinking about Revivex and a leaky rain jacket the other day. I'll check the Simms site for suggestions on using it now, and for future applications for waders.

The Simms site also has a very good method for repairing waders, and they show how in a video.

An update on the Gorilla Glue wader repair I detailed some time back. To sum up, it failed. The glue remained flexible enough for awhile, but in time it started cracking enough that the larger repairs started leaking again. So I had to tear off the old patches (no easy task) and will try to scrape off the Gorilla Glue and re-repair. This time I'm breaking down and getting Aquaseal. A failed experiment, but a good learning experience. Hope you learn from it the easy way.

Glad to help, Eric. Anyone know of a good solvent for Gorilla Glue? I tried 70% IPA, but it didn't do much. I don't really want to use acetone for fear of damaging the synthetics in my waders, but that will be next if no one dissuades me. Actually, perhaps I'll give ethanol or methanol a shot first. Any suggestions?

I don't know of a Gorilla Glue solvent, Shawn. Do they have a website that may give you some tips? I use Gorilla Glue to reinforce biots and parachute tie-offs for flies and to reglue felt soles on wading boots (since one does not have to dry the soles to do this) but I've never tried it for wader repair. Aquaseal is the best for this, I've been told. I've had such bad luck fixing waders I broke down and bought Simms waders last year. Simms will repair their waders (for a price) and pressure test them. I'll post an update on how that turns out when the leaks start. I've heard that LL Bean guarantees their waders for life. If this is true, that's another way to handle any leaks, which are probably inevitable.

P.S. If you try the boot repair, use short screws in the very edges of the soles to reinforce the bond. Be careful that the points have no chance of contacting your actual wader booties, though, or there will be more repairs to do at some point.

I absolutely love my Simms waders, but always use my LL Beans simply due to the guarantee (100% customer satisfaction). In the event that they leak and you're on a trip, such as Montana, they will next-day the new pair directly to wherever you're currently fishing...which is crazy, but incredibly customer-friendly. I've owned three pairs now, and endorse them (all have been stockingfoot). I've had one pair leak and LL Bean immediately shipped me a brand-new pair and a shipping label to return the old ones.

the cheapest wader repair stuff is a good old fashion rubber worm that is melted and applied to the gap or hole

I tried 95% ethanol to break down the Gorilla Glue, and I'm happy to report that it did the trick quickly and easily. I'm going to stick with that and won't risk using acetone.

Aquaseal is a better, higher grade of "Goop" I am pretty sure, and does not peel at the edges like Goop does.
