Salmonflies
Pteronarcys californica

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

Lateral view of a Psychodidae True Fly Larva from Mystery Creek #308 in Washington
This wild-looking little thing completely puzzled me. At first I was thinking beetle or month larva, until I got a look at the pictures on the computer screen. I made a couple of incorrect guesses before entomologist Greg Courtney pointed me in the right direction with Psychodidae. He suggested a possible genus of Thornburghiella, but could not rule out some other members of the tribe Pericomini.
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.

Great info and photos. Fishing Catskills for first time, didn't know what a blue quill was. Looks like an #18, will a sparkle dun tie work?
Great Photos

Jason, as noted before the photos of the ventral side, from the fish's eye view are great. These Show the lighter edges of the segments that Gonzo often imitates with lighter thread. I've been tying some of my baetids and paraleps with a unithread body ribbed with a lighter color (twisted to make the rib thin) and the trout seem to like it. I sometimes, (when I remember) add a coat of thinned flexament, which preserves the true thread color when it gets wet. I'd be curious to hear others ideas about Blue Quill imitations. A parachute has been working as well as Gonzo's upside down comparadun tie, one of which was readily gobbled (and seated in the lip on the hookset) by a nice spring creek brown as I hit the tail end of the hatch after a day of nymphing yesterday.
