Caddisfly Limnephilus flavicornis
Sitting on the edge of a small, not particularly well maintained pond in London in April 2019, I was staring into the water fascinated by the various examples of aquatic life, and by these irregular clumps of debris floating around in the water at the bottom of the pond.
It suddenly occurred to me it was still water, so why were these things moving?
I took my camera out and focused it beyond the reflecting surface and soon realised this was actually some kind of alien species recently landed on Earth.
I was quite disappointed to eventually find out it was Caddisfly larvae.
It's taken me those 19 months and a lot of research to feel reasonably confident of the specific species ID.
Watch in close-up as these larvae somehow navigate their way around the water, dragging with them, what in effect is a house :
Limnephilus flavicornis is a caddisfly in the Limnephilus genus.

Found a pretty good larva reference photo on dutch Wikipedia to confirm your ID, and thanks for taking the time to research it well:

It's a relief the effort to find an ID wasn't wasted, because I find the video endlessly fascinating.
The case is well built, just not very streamlined when compared to the cases of other larvae.
Probably better protection though.
