Pteronarcys californica

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

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.

Great pictures of the Quill Gordon. I am aware that color means nothing but these pictures of the body are much more yellow than the normal mahogony body color. I also noted you took them in May and this seems late for them to be around for that area. Are you sure the species is correct?
