In this image you can actually see that ‘the thing’ consist of eggs, and I have found that if I take this or more, and gently fishes them up from the water they are found in together with water from this same source, into a smaller container and then leave it there after some days I have a small container full of tiny tiny black mosquito larvaes. You can also see some of these in the first picture.
I will put in a picture here to show more of the container I keep it in, and there you might also get an impression of the actual size it has. Its just a small ceramic flower pot. These egg things are quite small and I had never noticed these before. One such thing would be maybe half a cm long
It does however take some days before the tiny mosquito larvaes are actually big enough to be fed to grown paroes 🙂 – but thats not a problem …
