Hello Eugene, it's not a Carcelia: Scutellum & tibiae are black.
Greetings, Eric |

Generally very valid arguments, but iliaca can be very dark. Given habitat and Thaumetopoea, this still is a likely C. iliaca to me. Theo |

Hi Theo, habitat and Thaumetopoea doesn't necessarily mean C. iliaca. Pales, Winthemia, Phorocera, Zenillia are out, but Exorista and Phryxe parasitize Thaumetopoea, too. And this one looks so completely differant to my iliacas: eklans attached the following image:  [176.56Kb] Greetings, Eric |

Correct, not C. iliaca because there are discal bristles on tergits but I don't see where to go.

Hello Eugéne, I've checked the flies, that the T&H key associates with the OPM and could exclude these: Carcelia iliaca Pales processionae Phorocera grandis Winthemia venusta Zenillia libatrix Remain: Exorista segregata Phryxe semicaudata (with my limited knowledge: possible) Greetings, Eric |

Thanks for the job ! Phryxe should match, there are 4 dc post. It may be P. caudata or P. semicaudata and caudata seems to be mediterranean. Greetings. Eugene |

Hello Eugéne, besides the southern occurence of caudata we can see one feature to separate caudata from semicaudata on your photo: the pruinosity of the tergites: P. caudata should have black posterior margins P. semicaudata is entirely covered. Your fly might be Phryxe semicaudata. Greetings, Eric |
