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.

Hello to all, so I have a question: How does the Leisenring lift work when blind fishing? From what Ive read, Jim Leisenring utilized his now famous technique when anticipating or actually seeing trout present in good trout lies so that he could induce a take. Basically, the lift is effective when trout are feeding on nymphal/pupal forms in the process of emerging and he would stop his rod to imitate the emergence of the insect as it rose to the surface correct?

How does the Leisenring lift work when blind fishing?

In my opinion its not unlike prospecting with a dry fly when there is no hatching activity present, or at least evident to the angler. You can "pound up" a willing trout with a dry fly without ever seeing it rise. Some fish may be looking for a meal, or they were stimulated to feed when you presented your offering. Think attractor patterns...They are designed to get the fishes attention and are "in the ballpark" in terms of something a trout would eat.

After years of fishing an area an angler understands what bugs should be hatching and it isn't a bad idea to search with say an emerger, or a nymph of a fly you anticipate should be around or on the water.

There are likely places a fish might be in a river...Bubble lines, near structure or behind rocks, and tossing a fly there in slow periods might get you a fish.

Fishing "blind" in either case, dry-fly or nymphing, can, on the other hand, be like trying to find a needle in a haystack. You may pound the river into a froth, but if the fish aren't interested, inducing them to do anything may be futile.

I once asked our own Tim Neal what he did during a Trico hatch...Tim is what we call around here in Michigan one of the Grayling Boys and they have their own take on fishing either the Manistee or the Au Sable. It usually involves what the rest of us would call large flies...

Well...Tim's answer was that he ignored the Trico hatch and just slept in like any civilized fella should, and after the hatch was over, and the angler has finished his breakfast, and that second cup of coffee, he would hit the river and run a small Madsen Skunk through the feeding lanes.

I asked him what he considered a "small" skunk, and he said a size 10...:)

Nothing pleases a Grayling Boy more than when the large flies show up and he never has to go below a size 10 for any reason for the rest of the season...

Rusty Gates had a fly he called the White Not/or Knot (depending on who you asked). It is an Iso imitation and from late May or early June you can fish it as a prospecting fly...Iso's can be around almost anytime between late May and say September (give or take)...I have fished it right along logs in the river in the middle of the day, when absolutely nothing was going on, and shocked old man Brown trout from his slumber there and caught some nice fish...No hatching activity going on, and no rises. Rusty called it "working the lumber, or running the logs".

It is slow fishing, but if you are good at it, and take your time, and can put your fly right up against the structure, you can pick apart a river on an otherwise slow day.

You should be getting snagged from time to time, or you aren't close enough to the timber.

But this is Au Sable fishing, not the Madison...We have lazy nocturnal Browns that hide all damn day up under under-cut banks, under logs, and wood piles...Sulky they are! This is why I have said that if a guy can consistently catch nice Browns on the Au Sable he will wet his pants when he gets to Montana...Out there, there is no place to hide...

I know this is a ramble, but somewhere in it all there is my answer to your question.


Oh...then there is getting up really early and being the first guy on the river and prospecting with a spinner that was around the night before, but that's another story...

Extremely true, Spence. I catch plenty of fish on my home waters that are not actively rising but will go for an Elkhair caddis, Adams, Royal Wulff, etc. My latest "secret weapon" is a #10 cricket pattern, which is not only tearing up the brookies now at [REDACTED] Pond but got three browns for me on the Rifle last week. The reason I tried this pattern? I have been hearing crickets singing at night, seems awfully early but they're there, and apparently fish like them too. I am thinking of it as "pre-hopper" fishing...

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