I found this possible Anthomyiidae species in woodlands near Ede (NL) on July 13th. Is it possible to ID it? Thank you.

I can't seem to upload the pictures so I've put in a link to the photo's on waarneming.nl:

It is Muscidae, probably Coenosia mollicula.

That's a surprise. I keep confusing these Coenosia's with Anthomyiidae :)
Thanks Niels-Jan!

It's a pity, the only thing that could be determinant to confirm this, namely the calypters, is blurred. :|

I still have it so I'll try to capture the calypters better. Thanx!

Anthomyiidae have a small ventral seta on hind tarsomere near base. Muscidae don't have this (except one one small genus). This is visible in your last photo.
Attached Zaphe divisa hind tarsomere to show this character.

Hello Michael, thank you for this information. I will keep that in mind.
You mean that it's not present on the hind tarsomere of the fly in my pictures? Cos I can't see it ;)

Iolaire, your fly is for sure a Coenosia (Muscidae), so it hasn't the Anthomyiidae tarsal bristle.

The genus of Muscidae which have this seta is Drymeia, according to Adrian Pont when I asked him about it. I have not found any anthomyiids without it, but I can't say it is true for all species.

I'm not surprised. I have always taken the Drymeia genus as the "bridge" genus betweenboth families. Drymeia share many characters with Antomyiidae (small calypters, hind tibia with more than one pd, etc.).
