it seems tachinidae to me (?), about 6mm, cylindrical abdomen, hairy. I beg you pardon, I have no camera, so this is a bad scan!

I think I?m sure this is tachinidae; cylindrical abdomen too, but bigger (a little more than 1cm), hairy too |

Hi Nigella. Sorry, but the picts are too small to give a definite opinion. But first impression is that most, if not all, are actually Sarcophagidae or Calliphoridae. A very very crude, but nevertheless quite effective rule of thumb goes like this: Arista bare -> Tachinidae (or Sarcophagidae Miltogramminae) Arista plumuse -> Sarcophagidae / Sarcophaginae, Calliphoridae or Muscidae If all the animals in your pictures have plumose arista, most will not be Tachinids Theo |

thanks for the effort! I was only considering the big bristles at the end of the abdomen  |

Arista (Theo means allmost) bare can also mean Anthomyiidae. More slender species. But not on these pictures, that's quite clear. |

I?ve read there is a exception in tachinidae, but I?m not sure if it?s exoristinae or just exorista they have the arista not bare; I still have no lenses, maybe next week I?ll see thanks everybody |

The exceptions are Dexiini and some Tachininae, Thelaira being the most prominent example. Dexiinae have, in general, long legs and a distinct longitudinal facial keel. But my advice is: start understanding Sarcophaginae, then you will pick out Dexiini in due time. Theo |
