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.

Setvena wahkeena (Wahkeena Springfly) Stonefly Nymph Setvena wahkeena (Wahkeena Springfly) Stonefly Nymph

Dorsal view of a Setvena wahkeena (Perlodidae) (Wahkeena Springfly) Stonefly Nymph from Mystery Creek #199 in Washington

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.

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.

John, here are a few Delaware River trout, caught with Bruce Miller, who guides out of the Delaware River Club. Al Caucci is out of the business there, though he still runs annual trips in Montana.

Louis, excellent! Thank you!

I never fished the Delaware from a driftboat, we always walked and waded the river. Of course back in the early 1980's I am sure it was probably less crowded and easier access than now.

Thanks, Mike. I understand you have some beautiful country up your way. Hope to get up there someday.

John, I waded the West Branch last year. Got beat up by a couple of impossible fish, caught a few smaller ones, then the next day had some great action a bit farther downstream. It can certainly get busy these days, and some of the fish get almost impossible to catch. They see too many flies. Some of the guides tell me they'll just move on when this happens.
