Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.

Spring is here as of yesterday, actually. :)

Whoever set the official dates clearly didn't live in Fairbanks.

Wow, I can't believe the difference in a few degrees of lattitude! I walked one of my favorite early season wild brook trout streams on Wednesday--there was more than 2 feet of compressed snow along the banks AND this stream is located very close to Great Bay (estuary) and of course, the Atlantic ocean. My favorite streams up north probably will not be fishable until early May. You are very lucky. By the way, those trout are sublimely beautiful. You found the BEST way to open a new season!

Great job, Smallstream. I'll be out soon enough. The water was really high during Spring Break last week - killin' me.
