Hi Bart, it's a male and it's has black hairs. The wingbase could be bald - without scales:
Nemophora prodigellus? I've never seen it, but it flies in Poland (Fauna Europaea).

Hi Eric, thank you for your suggestion!
In the meantime I talked with another person who specialized in Lepidoptera, and he also suggested another two species: Nemophora fasciella and minimella. It looks like all three species are unable to identify from a picture apparently.
Cheers!
