Dears,
I have collected this specimen in central Italy (Senigallia) 50 a.s.l. Individuals have emerged from mined spinach and chard.
I do believe belongs to genus Pegomya. Is it possible to get to the species level? I send some pictures (but I can do more of them, if you may suggest me which part is important for the identification).

Thank you.
Best,

Giorgio
