The victim looks like a Drosophila, but I'm less sure about the predator. Could it be a Tachinidae? Thanks, Sarah |

Hi Sarah, From this view the fly looks remarkably like a Tachinid, but it can't be. A Tachinid would never (?) attack another fly. Moreover, the abdominal pattern does not ring a bell. So, it should be somewhere in Anthomyiidae / Muscidae. But it fooled me for some time, too ! Theo Zeegers |

The 'headhunter' is a muscid (can't say anything definite about the genus  ). I think you are right about the prey being a drosophilid.

Thanks Theo and Kahis. I'm still very bad at distinguishing between Tachinidae, Anthomyiidae and Muscidae. I don't suppose there are any easy pointers that might help me  ? Sarah |

Could it be Coenosia attenuata? Sarah |

Hi Sarah The question to your answer Anthomyiidae / Tachinidae is really very simple: nearly all Tachinidae have vein M in wing strongly curved upwards (as in both Calliphoridae and Sarcophagidae) hardly any Muscidae (Musca, Neomyia, ...) and no Anthomyiidae have this feature: all vein M straight. But one can't see the wing venation in the picture, alas Theo |

Thanks Theo. Next time I'll try and take at least one picture with the wing venation showing so I can study it with calm, Sarah |

Details of chaetotaxy are not visible but considering its coloration (especially legs) it could be a male of Cenosia tigrina, Muscidae. Martin |
