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.

This is really a cool web site! I like all the pictures of the nymphs.
I love centerpinning with nymphs as I can really get great drifts and hammer the trout. Just moved to central PA from the Syracuse area and am anxious to pin the Little Juanita, Bald Eagle Creek, and Spring creek.

Would love to meet some other pinners on this web site to show me around the local rivers.

Hello, Black Gnat. I believe you are more likely to encounter flyfishers than centerpinners on this forum, but we are a friendly lot, so welcome aboard.
Best regards,

Are you wondering what center pin fishing is? So was I.

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."

The very long rod, 11' - 14' helps keep the mono off of the water and the reel looks like a fly reel but is actually a specialized reel that spins very freely on ball bearing races. Live nymphs, single eggs, and Glo-bugs are great for trout and steelhead.
