Hello everyone, I would appreciate a bit of help with this one ... Looks kind of special, but I can't place it. Photos were taken on the island Bornholm (DK) in the Baltic on May 15 2022. All the best

Hello Walther, as far as I can see: a male Nemoraea pellucida (Meigen, 1824).
Greetings, Eric |

Thanks, Eric! Yeah, I thought about that too. It's just that its proportions seem wrong, somehow. But I'm sure you're right. Nemoraea pellucida is a very recent addition to the Danish fauna. Perhaps even within this decade. In all likelyhood. Walther |

I'd go for male Winthemia cruentata. Theo |

Thanks Theo, The proportions of the fly are wrong for Nemoraea pellucida, and yes, they fit much better with Winthemia. A shame that it can't be determined to species level. But we can live with that! Walther |

cruentata is mentioned for Denmark, and rufiventris is not. Theo |
