Hello,

I'm new to this forum and to ... diptera! The one I saw convinces me to look closer at these insects.
I thought it could be Chaetorellia carthami; I received another suggestion: Orellia tussilaginis or "affiliated".
Could you help me to identify it?

Location: Tours (Center/West of France), near Loire river.
Date: May 2005
Body size: about 8mm.
