Psychodidae True Fly Larva Psychodidae True Fly Larva

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.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

I was going to say Neophylax as well. When did you take the photo? I thought they were summer aestivators and fall emergers.

Each specimen optimizing flow velocity creating a group pattern that tracks the laminar flow like smoke in a wind tunnel?

I was thinking this would be another good project for a mathematician trying to discern emergent properties in complex systems.

The specimens were collected, photographed and identified on Tuesday March 5, 2013. Same day as the photo of the rock was taken. I do not have the species key for Neophylax so I can't tell you what actual species we have there.

Neophylax ornatus is a widespread common eastern species which emerges in a couple months rather than in the fall like most Neophylax. But there could be other species that emerge early as what is known about life history for most of the species is based on very few records/studies.
