Hi, is it possible to determine the specie of this larvae? I suppose they could be Hydrellia sp. I found them in a pond of Rome, Italy, feeding on Lemna minor. Pupation within the mine. The adults walk on the duckweed.

Hello Flami, welcome to the forum
looks like Hydrellia indeed, but ID to species level in most cases impossible. Perhaps Tony Irwin has a suggestion. He also did on my post/photo:

Hello atylotus, thank you for your answer! I have already read your post, and i found it very helpful. I suppose it could be a larva of Hydrellia albilabris or H. griseola, because of their distribution that includes Italy. I have other pictures of the puparium and the adult that could be helpful for the identification, but i have encountered some tecnical problems uploading them.

This is very likely to be
Hydrellia albilabris or
griseola (the species most frequently associated with
Lemna). They are easily distinguished as adults - see images in the gallery.

Thank you very much Tony for your suggestion! Here it is a picture of an adult. Maybe
H. griseola?

Difficult to say while it is wet. But it looks very black, so I suspect
albilabris.
