That's a gorgeous and very well preserved specimen!
Larvae of what?Hexapods?
I have seen a similar one in a book on the Green River Formation labeled as Bot Fly larvae.
If you look at this under a microscope, there looks to be small hairs on it.

What book did you see the reference to Bot Fly larvae? I have found plates with several individuals on it. It looks as though they fell into the lake at the same time so I wonder what they were feeding on. No leaves nearby but I wonder if they swarmed similar to modern tent catepillars.
