Thank you very much!
I also read that they live much more longer in low temperatures so I'm moving it to the window's ledge, waiting for the spring. "Adults feed on the pollen and nectar of flowering plants" according wikipedia.
Thanks to this discovery now I will know what to do if see more of...
I found it in the wall of my room (I live in a flat near a river)
It's about 4-5 mm long and 1'5 mm wide.
It seems to be terrestrial.
It has 6 legs in the upper half and it's yellowish white below.
The shape is like a flattened cylinder.
I don't want to leave it on the street how I fed it? :cry:
I just found this insect and I don't know what is it. It seems to be the larva of a fly or maybe a little butterfly. I live in Spain so it is fall. What should I do with it?
