Hello EsinM,
Probably F. ruficornis judging by the grey abdomen and the pronounced frons. Could you make a picture of the bands on the abdomen and the arista?
Kind regard,
Ectemnius

Wow, I hope it is ruficornis - an almost fabled animal here in Denmark where it was not found since 1918, until last summer where it was registred again on Zealand! According to Bot & Meutter 2019, the colour of the halteres is orange in ruficornis and darker in F. cuprea - could also be worth a closer look.
