Last year I learned that most Dutch Calliphora are vicina rather than vomitoria - although only the latter is presented in some general insect guides. This one *might* be different I hope. I never saw such red beard, so could this be vomitoria? Switzerland, Tessin. Altitude 1400 m. July 26, 2007. Roadside through meadows partly mowed. Feeding on Daucus carota.

Red beard means vomitoria. You can also see the darkened calypter with only a very narrow white rim (vicina wide white border), the anterior spiracle is black (vicina yellow), as is the basicosta (vicina brown). Uralensis can have red in the beard, but it has bicoloured jowls, and your specimen has entirely black jowls. Susan |

Thanks for the extended explanation! Forgive me my ignorance, but I still don't know what the basicosta and the jowls are, so I would much appreciate some hints where to look for! Thanks for your attention Cor Zonneveld |

The basicosta is the little 'joint' between the wing and the body which allows it to move. Jowls are the side of the face under the eyes, aka cheeks or genae.
