I have no clue about this one (appr. 8-10 mm). I found it today on our terrace at Leerdam, Netherlands and when I saw it I thought it was
Paykullia maculata, which I see here almost every day. But although it has about the same 'jizz', it looks quite different. Most obvious on this all black fly are the shaded wings with the whitish tips.
Does anyone know this fly? Thanks in advance!
