Hello everyone!
I got passionated into photographing insects. I subscribed long ago to Diptera.info, but it's the first time I'm writing something here.
I took a picture of this Diptera on the first of May 2021 near Gorizia, Italy, in a humid karst environment.
Length: 3mm
Is someone able to identify the species or at least the genera?
Thanks in advance and congratulations for the best diptera website of the web.
