Think this is either Mesembrina meridiana or M. intermedia (family Muscidae).

Is it possible to tell the difference between these species from photos? Size is close to 10 mm.
Several of these seen at the summit of a mountain at 600 meters above sealevel (dry slope, above the treelimit). Location in Bodø, northern Norway (67 degrees north), date 29.06.2012.
