Good morning ! It looks like the supposed title species, but the fineness of its black spots and their shape is a bit surprising. Female (well separated eyes, large abdomen).  Bobabar : France : Cergy : 95000 : 07/08/2023 Altitude : 85 m - Taille : Lc = 4 - 5 mm (estimated) Réf. : 328293  Bobabar : France : Cergy : 95000 : 07/08/2023 Altitude : 85 m - Taille : Lc = 4 - 5 mm (estimated) Réf. : 328294 Bobabar, France, Cergy (25 km northwest of Paris) Edited by bobabar on 18-08-2023 09:15 |

Hello, looks like Anthomyia pluvialis (female) to me. Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

Please, what criteria are you looking at here to distinguish it from Anthomyia procellaris? |

With reference to the key for females in Verner Michelsen's paper: The Anthomyia pluvialis complex in Europe (Diptera: Anthomyiidae), Sytematic Entomology (1980) 5, 281-290, it can't be Anthomyia pluvialis: even if somewhat slender, the dorsal black spots are confluent with the spots at the wing base, so it should be either quinquemaculata or procellaris, but more likely procellaris due to the grey area on scutellum.
Best regards, Carlo |

Thanks you Carlo. Your arguments are ours in favor of A. procellaris. Other opinions? Edited by bobabar on 18-08-2023 09:18 |
