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.

And this one, also from the midwest, is more green than the sulphurs I recall seeing this season. My limited experience in PA streams suggests that many, if not most, of the sulphurs here are best imitated by pale yellow, bright yellow, or orange bodies. Gene, and others, am I far off?
