Note: I also saw the same things when I had venus flytrap plants. The pots set in little dishes of water and they absorb the water through the bottom, since they were in moss. Maybe you were right in saying it might be the larva of some kind of bug/fly/gnat or something But I'm not a bug expert so I can't be sure.
