#caddisfly larvae everywhere. They are interesting insects. They live for a year or more in the water. There they are astonishing architects for their cases.
If you look close, you can see a lot of Hydras on the pondweed. They are indeed special creatures. They are not ageing and don't die of age! They regenerate all the time. Very small but also very exceptional 🤩!
