This fly first looks like a tachinid, but I suspect it could be Nyctia halterata of the sarcophagidae. What is the verdict ? Thanks for your help. Size : less than 10 mm - Date : May 01 2007 - near Paris (woodland). Regards. Stephane Lebrun attached the following image:  [109.65Kb] Edited by Stephane Lebrun on 18-05-2007 17:37 Stephane. |

I think it's Nyctia halterata (Sarcophagidae)  |

Hey Chris, you're as swift as an arrow. Thank you very much. A question : may I consider the wing spine at Sc level as a clue or can we find it on tachinidae ? Edited by Stephane Lebrun on 18-05-2007 17:58 Stephane. |

Forget the question, I just have seen this wing spine on many dark tachinidae on your web site. So I think the hairy arista is the best clue (when it's visible)... Thanks again. Greetings. Stephane. |

Some tachinids have a hairy arista too ... but really splitting the calyptrates to family level is done on a combination of features and most of the definitive features (eg. subscutellum) are not very clear in the field. You can use rules-of-thumb but really a lot of it depends on just knowing roughly what each family looks like There's no substitute for experience  |
