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.

Female Baetidae (Blue-Winged Olive) Mayfly Spinner

This species is probably in Centroptilum, Cloeon, or Procloeon. I captured this spinner on the same night as a dun which is probably of the same species.

Jason-

The single detached intercalaries in the fore wing would limit the choices to the genera you suggest. The sharply pointed costal projection and single longitudinal vein in the hind wing probably narrow it to a single species. Unfortunately, none of the Baetidae hind wing illustrations to which I have access show either that sharply pointed of a projection or the single longitudinal vein, let alone in combination with one another.
