Musca domestica (M) or Graphomya Sp.?

This fly looks very similar to Musca domestica but I wonder if it could be something different because it was busily feeding on nectar - new Tansy (Tanacetum vulgare) blossoms in very diverse, mixed, grassland, 10m from a well wooded stream.

Size:- +/- 6-8mm

Flensburg, N.Germany:- 54.753966, 9.420891

Many Thanks in advance.
Ray

Hi,

looks like Musca autumnalis to me.

Hello Jürgen,
I did consider Musca autumnalis but none of the male examples I looked at, both in the gallery and forum, had prominent black and white thorax banding like mine. Female examples were well banded but not males. Thorax bristles on mine also seem longer than M. autumnalis examples.

Another question:- Do Musca domestica feed on nectar?

Best Regards
Ray
