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.

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.

added two rivers to my Yorkshire life list: Ure and Nidd. trout season was over so we were after grayling. they seem to live in the bits of the river that the trout don't: quieter water at the tails of pools and the end of riffles, mostly. they like nymphs down on the bottom, but they can be caught with dries as well.

Wow, that looks like a fun trip! Some "natives" there, back in the "Old Country"!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
