 Oryctes : France : Villeneuve-d'Ascq : 59650 : 01/06/2026 Altitude : 24 m - Taille : 5-6 mm Réf. : 374231  Oryctes : France : Villeneuve-d'Ascq : 59650 : 01/06/2026 Altitude : NR - Taille : 5-6 mm Réf. : 374232 Hello, I found this Dolichopodidae on May 1, 2026, in Villeneuve d'Ascq (Nord, France). It was resting on a leaf of Filipendula ulmaria in a wet meadow. I'm having trouble identifying it and I am even unsure about its sex (I'm leaning toward a female). Perhaps it belongs to the genus Dolichopus, but the partially red antennae and very pale legs (femurs, tibiae) seem unusual to me. I'd appreciate your opinions on this insect. Can we identify the genus, or even suggest a species ? Thank you in advance, Dominique |

Perhaps female Poecilobothrus chrysozygos? ... https://diptera.info/forum/viewthread.php?forum_id=5&thread_id=51198 |

Thank you, Manu70, for this suggestion. For the Poecilobothrus chrysozygos species, shouldn't there be a black spot on the hind femur (which is not the case here) ? |

In the linked post, this black spot is missing. I suppose that explains the conditional nature of the identification. |

I think it's a female Dolichopus. This color is common in North America.

Thank you, John, for your replay and for suggesting the genus Dolichopus. North America is a bit far from northern France. Could this pale colour be related to a recent emergence, as it has been suggested to me ?
