Blue-winged Olives
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.

A small, old rock wing dam has created an excellent riffle and pool in this classic trout stream.

Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva

Dorsal view of a Glossosoma (Glossosomatidae) (Little Brown Short-horned Sedge) Caddisfly Larva from the Yakima River in Washington

I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.

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.

Welcome!

There's a LOT of folks on this site who have experience on the Au Sable, and it's a (fairly) short drive from Cadillac over to the vicinity of Grayling and your destination. While you're in Cadillac give the Clam River(one of my favorites!) a shot, pretty good Brook trout fishing in that stream's upper reaches.

Tight lines,

Stop in a fly shop in Grayling. Either the Old Au Sable downtown, or Gates' Au Sable Lodge on the river on Stephan Bridge Rd, about 7 miles east of town. At either shop purchase the Au Sable river guide published by the Challenge Chapter of TU. Look up the section on the North Branch and any access upstream of Lovell's bridge. Easy wade. Not too deep. Brooks and Browns.

Have fun.

No clue about the river but I can tell you a wading staff comes in very handy. I realize many folks are nimble enough to lope around rivers pretty well but I like the help. I paid $40 for one that folds up small enough for a knapsack and it floats. Clip it to your vest so it doesn't get away and you're in business. If you get one, check the bottom for metal and coat it with liquid plastic. Otherwise every time you reposition it goes tink tink tink. Translated to trout speak it means run run run.
