I thought it was the first Phasia for the year. But when I look at the picture I see it´s something else. Rondania fasciata? (The male) Near Stockholm, Sweden. May 16. amaira attached the following image:  [197.03Kb] |

I think Rondania fasciata is correct: length petiole approx. = post-angular vein abdomen nearly undusted - tergites with yellow stripes basally Greetings, Eric K |

Rondania fasciata is much redder on tergites. I am thinking Graphogaster brunnescens male. Theo |

I haven´t seen any of them irl, and I do not have the fly. And the pictures is bad. Looking at pictures of Graphogaster, it does not look like it, I think. But I don´t know of course. In real life it really looked like Phasia barbifrons/pusilla. Same size and completely black. Graphogaster brunnescens can be found from end of June, this was in mid-may. |

In any case, your first pic is obviously a mistake, simce it is a male Bibio. Maybe better to remove it ? Theo |

First picture shows the small fly to the left. Bibio as a comparison. |

This is a typical Rondania fasciata https://www.naturbasen.dk/observation/1528769/rondania-fasciata As you can see, much more orange. That said, your fly has brownish spots on tergites which are surprisingly similar in shape. So this could be a very dark Rondania fasciata ? Theo |

I think it really is more brownish om the sides of the abdomen, although it´s hard to see. Sorry for the bad pictures, and thanks for the discussion and help. amaira attached the following image:  [174.03Kb] |
