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.

These two Rhyacophila species were collected from Mill Creek, a tributary of the Russian River. The first is probably a member of the Rhyacophila hyalinata group and the second is probably a member of the Rhyacophila betteni group.
