Hello,

I know this is such a difficult ID, especially on photos, but I'd like to have some more informations about the way we can at least precise the family. (7 mm - Saint Apollinaire (21), France - 15th August 2004)

Please tell me whenever I'm wrong : ;)



We don't see any post-scutellum, so it is not a Tachinidae.
So it should be either Calliphoridae, or Muscidae.




Photos don't allow to see whether there are hypopleural setae or not, which could discriminate the 2 families. :(

Is there any other visible criteria that can help making the difference ?
In case there is, then, how to go further in identification ?

Thanks for explanations !
