The plastic thing was grown in by some bacterial biofilm. The water on the biofilm was very thin, maybe thinner than the larva. The water was flowing slowly. To be honest id did not look like a very eutrophic environment, but the larva might have been washed down from the creak, which might have contained some more plant material. Possibly it is not important, but this fly was around in large numbers: http://xespok.net...1000028181 I do not really know what kind of fly this is.

There are many grazers in the Chironmidae of which the larvae go across submerged surfaces to graze the algae. Paul - - - - Paul Beuk on https://diptera.info

In fact the morpholohy is quite similar to some other Chironomid larvae, that I had seen before, though the color of this larva is not red (the others I saw were red, likely larvae of C. yoshimatsui), possibly because this species lives in a more oxygen-rich environment.
