Bill wrote I think they might be fly larvae.
They've got two body parts. a very small head and a larger body. Surrounded
by a bubble of oxygen. I can actually see them moving along the stems of the
Hornwort if I wait long enough

This reminds me of some caddis fly larva that I think I had in my filter a
couple of years ago. They don't eat plants but they might hatch indoors with
the warmer temperatures. If they are hard to round up you could cover the
aquarium (or container) with a double layer of netting to keep them from flying
around the house.
