Several of these flies landed around me as I sat on a bench. They were especially attracted to my leather shoes. Massachusetts, USA September 10, 2011.  (Click to enlarge or view on Flickr.)  (Click to enlarge or view on Flickr.)

I think Anthomyiidae. Perhaps Pegomya is possible - I can't see cruciate interfrontals - but I'm just guessing! |

Here are the wing base and head of a different individual. They have a paler tip to the scutellum, not really obvious because the area is small and out of focus here.

Better picture of head from another fly seen today in the same location. (Click for large or view on Flickr.) |

In the last shot I see some fine crossed interfrontals, which, in the British key, rules out Pegomya. I hope someone else can help. |

I have the upper side of the thorax of another similar fly. (On Flickr) |

I have captured one of these flies. They are very common again this week. If there is anything I could shoot to help ID I'll try (I have no microscope). I can send somebody a male. |

Perhaps Michael Ackland would look at a specimen for you? It's all in the genitalia, and I have no information about American anthos. (Looking again at the frons, I think the setulae I saw are probably on the parafrontal, so not interfrontals after all.) |

With an added photo of the male parts of a male Michael Ackland says Eutrichota. |

The last photo above is of a specimen identified by Michael Ackland as Eutrichota affinis (Stein). |
