Hard to tell from this angle. At least no quadrimaculata, because their males don't have spots on the tergites. |

I am sorry, I have been sleeping! This is quadrimaculata/barbifrons. You may kick my ass for this stupid mistake...

Hello Pia, Well, from picture 1 it?s clearly visible that it has densely haired eyes, and picture 3 shows a black face. Males of Melangyna barbifrons have virtually bare eyes and a black face with yellow patches, so this is clearly a male Melangyna quadrimaculata! Greetings Greetings, Gerard Pennards |
