Yes, it is a Linnaemyia. Moreover, it is a male with proclinate orbitals !! That should be a big clue (L. comta ?) Theo |

I took the key halfway. I was wrong especially early in the season, too many things forgotten![]() With the key, the second segment of the antenna corresponds to figure 50 and not 52. If in this genus, only the comta species has a male with oe so it's good. But the key is for all species present in France? |

No, key is incomplete for France. However, if sternite 1 has light hairs, you are pretty sure OK. Theo |

Nice find - that's a particularly rare species here in the UK and I have only ever seen 1 ... in a sample from Russia ![]() Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London. |
