Pteronarcys californica

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

Skwala (Large Springfly) Stonefly Nymph Skwala (Large Springfly) Stonefly Nymph

Dorsal view of a Skwala (Perlodidae) (Large Springfly) Stonefly Nymph from the Yakima River in Washington

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.

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.

Adults and larvae were identified using "What is Capnia umpqua? Frison (Plecoptera: Capniidae) distribution and variation of terminalia" by Baumann and Stuart.http://illiesia.speciesfile.org/papers/Illiesia05-05.pdf as well as "Larvae of Five Species of the Winter Stonefly Genus Capnia (Plecoptera: Capniidae) From California, U.S.A." by Stewart, Drake and Stark. http://illiesia.speciesfile.org/papers/Illiesia07-18.pdf

Larvae were found in shallow water 2-12 inches deep. They were found in riffle areas and crawled out on rocks to emerge. They were present from January through March.
