Hi,
These are Blackfly larvae (Simuliidae). Perfect food and i get loads in filter. They will cause no harm whatsoever. They are also filter feeders, spinning web like structures collecting debris from water column.

Yep, blackfly larvae, they love running water on waterfalls or similar, just scrape them off so that they are washed into the pond and your fish will enjoy the treat.

Running heater at low temp?
Covering the pond with polycarb should be enough to stop water temps dipping below 6C for the most...
