 Could it be Anthomyia quinquemaculata ?

Hi, I collected an Anthomyia sp. on September 9, 2025, near Valence, France. Using Michelsen’s key (1980), my specimen keys out to A. quinquemaculata. I’m aware that a reliable identification requires examination of the genitalia. However: - Valence is about 250 km north of the Mediterranean. That said, the Rhône valley hosts several Mediterranean species, so the presence of A. quinquemaculata here might be possible. - I don’t currently have access to a dissecting microscope or KOH, so I can’t examine the genitalia in the near future. My question is therefore: is A. quinquemaculata a plausible identification this far north, or would its known distribution make this unlikely? Thank you for your insights. If needed, additional pictures and precise location can be found on iNat : https://www.inatu.../336012314  |

Hi, firstly, I think it's not impossible to find A. quinquemaculata in the Rhône valley. - spot at wing base confluent with dorsolateral one - scutellum: only apex grey - in your additional images: ad seta hardly longer than mid tibial diameter (not "clearly longer" than in A. procellaris)!
