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.

Male Epeorus frisoni Mayfly Dun Pictures

I collected this male dun together with a female spinner, a female dun, and another male dun. I photographed this bedraggled one, larger than the other male, to show some of the greatest size variation within the species.
