Psychodidae True Fly Larva Psychodidae True Fly Larva

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.

I like how the green of this larva's body shows through the slightly translucent sand grains of its case.

I added several new bugs I collected this week to the site tonight, including this caddisfly. Anybody care to ID it?

To view all the new specimens, go to any page of this site outside the forum section (like the homepage) and look under "recent updates" in the left column.

I'll be adding some even better bug pictures tomorrow from a collecting trip a couple days later.

Jason-

My guess would be Psilotreta or another Odontocerid.
