Salmonflies
Pteronarcys californica

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

We were lucky to be able to fish through this storm as it skirted around us to the north, giving us just enough clouds to prompt a BWO hatch but keeping the lighting at a safe distance.

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.

Male Dolophilodes distincta (Tiny Black Gold Speckled-Winged Caddis) Caddisfly Adult Pictures

This caddis species was dancing high over the stream, spaced a foot or two apart across most of its width, very much like Ephemera mayfly spinners but with more side-to-side motion mixed in. There were more than enough to get the trout interested, but I wasn't able to stick around until they fell on the water (if they did at all).

This is a male dolophilodes, probably distinctus.

You can distinguish philopotamids from hydropsychids by the ocellar head warts that are absent in hydropsychids.

D. distinctus is everywhere, along with Oecetis inconspicua, including perhaps the moon, inner four planets and in orbit. it is a beautiful insect however.
