Blue-winged Olives

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 everyone,

My name is Kyle McClelland and live in Manistique Michigan. Just came across this site and thought it was really cool! This season was my first season of chasing steelhead, and Brown trout with the fly rod. I started out in December, and on my first expedition I managed 11 steelhead, and two brown trout. After that I was hooked! Made the trip down to the Big Manistee river this spring for spring break and caught a bunch of Steelhead, and a few small browns there. I just started tying my own flies end of December, and now I will never buy another one. Overall Hex nymphs, rock worm nymphs, stone fly nymphs, spey buggers, and egg sucking leaches have been best Here are a few of my favorite pics this season.

Thanks! It has been a great season for sure! Once I started swinging streamers it will be hard to go back to nymphing!:) Going on my first brooke trout fishing adventure this weekend as the season opens this weekend.

I have to give credit where it is due my brother; great freaking work haha!!! Those fish are all beautiful and caught on the right equipment ;) It is good to hear that you will be tying your own now because we can all agree that catching these fish on self tied flies is an incomparable feeling to the store bought ones. Keep us updated on your adventures and we will do the same. Nice work. And was it the Manistee River that you fished where the dam (or whatever contraption that is) is in the background for some of the pictures?
Most of us fish our whole lives..not knowing its not the fish that we are after.

Thanks!! Yeah, I agree completely about catching them on your own flies! The first Steelie I caught on my tied flies was a 8lb male on a rock worm nymph in January. I will be sure to keep you guys posted, and look forward to keep reading reports! This is a great site for sure! When I fished the Manistee I didn't fish Tippy at all because there wasn't hardly any room to fly fish. I fish from the boat launch at Tippy down stream, past the saw dust hole. Best spot was probably sucide bend. Fished 4 days down there and hooked around 100 or so. It was a lot of fun!

Jonathon...You out there buddy? Its time to put down that 3wt me thinks! These young Michiganders are making us look bad. First Jim's daughter Varilya and now Kyle...We're not careful them DNR boys may pull our fishing licenses..;)

All kidding aside. Nice job young fella. You too Varilya...Its nice to see you two outside with rose colored cheeks and not cross-eyed from starring at them computer gadgets. :)

Good luck to both of you with the upcoming season...My car is packed and pointed towards Grayling and I'll be joining both of you astream this weekend...:) Tightlines!
