Hello, I even managed to get the head of this Sarcophaga sp. reasonnably sharp, but in vivo. Just for the fun. Edited by pierred on 11-12-2007 07:48 Pierre Duhem |

I doubt this is Sarcophaga sp. Do you have pictures of thorax and abdomen? Liekele |

This is a female of Agria (Sarcophagidae, Paramacronychiinae). In Europe three species. For identification we need to investigate / dissect the postabdomen. If the specimen has been bred, hostname might help further identification. Liekele |

Paramacronychiinae, is this subfamily parasitoid???  Definitely flies are amazing!  |

Is this subfamily parasitoid? Some of them are, some aren't. But I assume this subfamily to be paraphyletic. For example: Agria is parasitoid on lepidoptera and some symphyta. Some Brachicoma in nests of Bombus. Sarcotachina on eggs of Acridoidea. Nyctia from snails. Wohlfahrtia nekrophag, myiasis or parasite of mammals. Liekele |

Liekele, what features made you think that this is not a Sarcophaginae fly. I would have classed this a Sarcophaga sp without hesitation. It appears that the situation is far more complex than I thought.

Hello, Well, Gabor took the words out of my mouth... Xespok wrote: I would have classed this a Sarcophaga sp without hesitation. It appears that the situation is far more complex than I thought. Thanks for the identification as Agria sp.. The fly was not collected. Edited by pierred on 04-10-2007 05:49 Pierre Duhem |

Hello, I'm sorting some older photos and looking at this Sarcophagidae, I'm asking myself if it could not be another Agria sp. Pierre Duhem |

No, this is clearly a Sarcophaga s.l. Very difficult to explain why.The bristles on the parafacialia are differently placed, the face is yellowish (whitish is very unusual in Sarcophaga) and the abdomen is more elongated, whereas Agria is slightly more Muscid-like. Agreed, all very subtle. Theo |

I've been losing sleep over this one -  I'm really not convinced that this is an Agria. Pierre's photos show a fly that is quite unlike the Agria in http://www.dipter...ad_id=8185 (which I am happy is an Agria). Pape clearly states that Agria has black occipital and postgenal hairs, which this clearly doesn't. I suspect Pierre's fly is a male (look at those pulvilli!) Sarcophaga (Bercaea) africa. I shall be away for a few days, so shall be interested to see what opinions there are on my return!

The thorax looks a bit bald? In my recent S.africa it has few long bristles on it. Is it just a photo problem? |

Now I feel guilty. You're right, this is not Agria. I was mistaken by calling it Agria. It is Sarcophaginae after all. But I do not know which one without genitalia. . I suspect Pierre's fly is a male (look at those pulvilli!) Sarcophaga (Bercaea) africa.[/ Maybe. It is not Agria. And it is different from first specimen with beautifull picture of head. Liekele |

Hello, Don't be sorry, all of you. I'm the only culprit, having thought that this could be the same species. Pierre Duhem |
