This fly flew around low in sparse vegetation (like a Tachinid). What family does this belong to? Southern Norway, Agder 14 August. 7.3 mm.

I'm still curious about this fly. It has some kind of subscutellum - could it be Tachinidae? |

Hi Morten. I'm not an expert, but I had a go at this with the T&H key and arrived at Loewia foeda (male). But don't take my word for it! Best wishes, Stephen. |

I'm not sure. The petiole in the wing venation is very long for foeda and the second antennal segment is nearly always yellow in female foeda, at least in Central European ones. Did you consider L. erecta Bergstroem, 2007 ? Theo |

In any case, it is clearly a female. Theo |

Thank you! It seems that L. erecta has been found in Norway. It is not described in The Tachinids (Diptera: Tachinidae) of Central Europe. How do you distinguish them from the other Loewia? |

Thank you so much, John! I'll see if I can figure it out from the link. Morten |

With yellow-brown halters and a size of 7.3 mm, I think this is keyed out to the foeda. (with the exception of the 2nd antennal segment) L. erecta keys out as L. phaeoptera or occasionally as L. adjuncta in the hitherto available keys. Morten |

I agree that 7.3 mm typical foeda-size is. That said, other features are aberrant. Scandinavian foeda in my collection are typical. So either you have an aberrant individual or something is off…. Theo |

that qualifies as “off” as well. Better not jump to conclusions and wait for a second specimen. Theo |
