In
Musca domestica, the frontal vitta should be not less than three times as broad as one fronto-orbital plate. Here, it is clearly narrower, at most two times as broad as a fo plate.
Females M. autumnalis have usually a darker abdomen than males, often completely grey.
This female is either
M. autumnalis, or
M. larvipara.
