I think this is also Pollenia sp, but a worn specimen.

GAbor is right IT is Pollenia, one of the 2 black species amentaria and atramentaria (yes, I know, don't kill the messenger) Theo |

Well... in Google I search for Pollenia amentaria and I found one Photo: It Looks so different from the fly that I've photograph... Maybe my Fly it's a Pollenia atramentaria  Malcolm Storey said that: "If it had the golden hairs on the thorax it's probably a Pollenia" But where are the golden hairs ???

He, you make a logical error. If golden hairs then Pollenia. But not all Pollenia have golden hairs, Malcolm never said that ! The picture above might be amentaria, but it is very atypical, probably caused by the flash. Theo |

Professor dr. philos. Knut Rognes (arbeid: Universitetet i Stavanger, Det humanistiske fakultet, Institutt for f?rskolel?rerutdanning, N-4036 Stavanger, Norge He said that: Yes, Pollenia leclercqiana (Lehrer, 1978), male. I can identify it on the dark colour, narrow frons, and stalked R5 in the wing. Known from Spain (incl. Balearic Is) and France, pluss North Africa. First records from Portugal. Congratulations! Good. Thanks a lot. |

Valter - the golden hairs fall off (or get rubbed off) Pollenia very easily. When they are freshly emerged, all the species have golden (or silvery) wavy hairs on the thorax. As they fly around, they lose them, and in the spring after hibernation, most of them look more like yours - though usually a few hairs remain on the sides of the thorax. The species differ in the pattern of dusting on the abdomen and thorax, in the chaetotaxy (bristles) of the thorax, in the wing venation and in the proportions of the head characters. For most of us, looking at the genitalia is the easiest way to identify them with certainty. Knut Rognes is the acknowledged expert on the group, and can use his experience to name them from non-genitalia characters. (There's nothing like years of experience!)

Nice to have an ID by Rognes, I believe his call virtually with closed eyes (in Calliphoridae, that is). Theo |
