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.

probably polycentropus, like earlfisherman said a good closeup of the anal claws would be helpful. esp any teeth or serrations on said claws. nice pics.

Based on the head pattern, this larvae might be Polycentropus sp. or Neureclipsis sp., I find myself leaning towards the former but I've been wrong before. It's hard to tell for sure without close up photos of anal claws and legs. You can tell it isn't a Rhyacophilid because there isn't a sclerite on top of ab seg number 9.
