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.

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.

Mayflies DVD Review

I bought the James Marsh DVD on Mayflies as advertised on Troutnut. Cost $34.95 w/ shipping and got w/in about 7-8 days, not bad. The DVD sound quality was a little weak at times but not bad; overall it was very informative though! The host, James Marsh, takes you through all of the major Mayflies w/ upclose shots, Latin names, and common name. Overall, I'd give it about a B. Solid stuff and defintely worth getting but could be a tad better in terms of sound quality and maybe providing a scenario where he (James) himself actually fishes and exhibits his thought processes from initial arrival on-stream to actually successfully catching trout. Still though, solid and recommended!!
