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.

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.

My interests have returned to midge fishing again for the late fall and winter. Anybody care to share any of their favorite pupa or larva patterns? I've tied flies from the Midge Magic book by Koch and Holbrook and have had success with several of their patterns.

I never saw a wild thing sorry for itself. A small bird will fall frozen dead from a bough without having felt sorry for itself.

When asked what I just caught that monster on I showed him. He put on his magnifiers and said, "I can't believe they can see that."

White, metal bead head works best for me overall with varying abdomens, and thorax.
