According to the draft key by Falk that Chris forwarded to me recently, C vomitoria is not so strongly inclined to live in close association with man as C vicina. It becomes the dominant species in upland areas in the north especially in moorland sheep raising areas, and is more of a woodland species in the south of the UK, suggesting that it prefers cooler environments. It also prefers larger carcasses, presumably because its larvae develop more slowly than C vicina. See also Species composition and larval habitats of blowfly (Calliphoridae) populations in upland areas of England and Wales by l Davies in Medical and Veterinary Entomology (1990) 4, 61-88 (many thanks to John Bratton for sending me this article).

Juergen this is quite a useful series of photos. Could you upload the second of your links (the one looking straight at the face) to the gallery please?
