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
