Hello! I have the impression that Calliphora vomitoria is more numerous in relation to the ubiquitous C. vicina here in Ostwestfalen/Germany this year. I find her rather often on umbelliferous flowers in the forest recently, attracting my attention from a distance because of being considerably bigger and appearing darker. Is it possible that this species is more restricted to woodland than C. vicina, which I find almost everywhere? Addtional pics: http://www.foto-u...ria_W3.jpg http://www.foto-u...ria_W4.jpg And two postings (in German) with more pictures: http://insektenfo...eadid=9964 http://insektenfo...eadid=9279 Edited by Juergen Peters on 25-08-2007 22:21 Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

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?

Hello, Susan! Many thanks for your explanations! They match my observations. 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? I will try it later. I have never before uploaded a pic to the gallery. Previously my photos were too bad with my old camera, now I have so many pictures of flies that I couldn't decide yet, which of them to upload  (of species not there already). I must admit that the first photo I had considered to upload was one of a male Calliphora vomitoria:http://www.dipter...ad_id=4957 My first halfway good picture of that species...

Juergen Yes - do upload that one as well - it shows quite well the enfuscation of the squamae, with the lower one very dark with a very narrow very white edge. Vicina has a broad white edge, so this feature can be useful when you don't have such a good view of the face. (Beware loewi and uralensis if in this situation of course.) Susan |

I will search my photos for some other halfway succeeded pics of diptera, which are not in the gallery yet, and upload them together in the next days.
