Salmonflies
Pteronarcys californica

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

This little pool in update New York is enjoyed by many tourists every day, and it still holds a few trout -- stockers mostly, but you can't complain about the setting!

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.

I believe Lepidostoma has antennae fixed very close and right in front of the eye. I don't see that here. Maybe it's obscured in the image?

Yeah, I can't make them out either, but my eyes are pretty blurry this time of night... The antennae are very hard to make out at any time though, usually looking like a tiny pale dot next to the anterior margin of the eye. There's not much to 'em. In a good microscope photo in lateral view, they look like the plunger end of a very tiny retractable ball point pen to me. For me, the best (and easiest way) to identify them is by their having lateral humps on the first abdominal segment while lacking a dorsal hump. Others either have all three or lack them entirely and the cases are different.

I see. Found another web image and the antennae are indeed obscure.
