Hello,
I am keying this fly out at either of these families, but neither really fits, for example, there ARE Interfrontal bristles present, and the wing is NOT marked, so I’m not sure this could really be either of these families.
From the key (Oosterbrook 2006 European Diptera):
Scathophagidae
Katepisternum w i t h 1 large bristle (fig. 394) or w i n g darkened at the base,
along the costa and at the tip. Interfrontal bristles absent.
Tephritidae
Almost always several lower pairs o f F-bristles curving inward (fig. 328).
W i n g often marked; cell cup nearly always closed by a geniculate vein
Q1A2 and w i t h an acute apical end, v e i n C u A 2 rarely straight or convex; no
transparent line in basal part o f the w i n g (fig. 330, 331).
About 10mm from head to abdomen tip
Does anyone have an idea? I'd be so grateful for any tips!
many thanks!

The long ovipositor and haired R1 vein put it in superfamily Tephritoidea. The course of the subcosta looks right for Tephritidae. A few species have unmarked wings.
