Blue-winged Olives
Baetis
Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

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.

Another unusual bug day for me today. When I took my boat out of the river there was a very large black bug with long antennae on the transom of my boat. Called a guy over, and he knew what it was, a certain kind of pine beetle, and I forgot what he said the first name was. He said they can pinch, and draw blood. It was a good two inches long, and before we left to float the river there was a bigger one on its back in the womens room that couldn't turn itself over.

That sounds like a pine sawyer, a beetle in the family Cerambycidae. Did the antennae curl up a bit at their ends? Some of them do have pretty strong mandibles so handle carefully! Some of them can also make noise by scraping their wings, its called stridulation, and they do it when you try to pick them up (happened to me at the U of M Bio Station when I found one sitting on my alarm clock one night).

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Yes, the antennae did curl up at the end. First one I have ever seen.
