Hallo doesn't this fly have a little to much white in the face to be carnaria? Estimated length more than 20mm. Maja dipdip attached the following image:  [90.93Kb] |

Hi Maja Facial colour may be a guide, but is not necessarily reliable. Your specimen looks to be quite fresh (no obvious damage to the wing margin), so we expect the facial colour to be bright. As the fly ages, its colour will change, and I would expect this fly to develop a slightly yellower colour. This happens in a number of families. In the Ephydridae, some old individuals which had developed a golden, rather than a silver face, fooled one dipterist into describing them as a new species. With Sarcophaga, it is usually necessary to examine the genitalia to be sure of the species, and this is certainly so for the Sarcophaga carnaria group, all of which look very, very similar.
