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).

Hello,

looks like Anthomyia pluvialis (female) to me.

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

You mentioned it already: the thorax markings are much thicker in A. 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.

Thanks you Carlo.

Your arguments are ours in favor of A. procellaris.

Other opinions?
