Gymnosoma nudifrons, Gymnosoma rotundatum. I know it is verry difficult to determine these flies from a photo. I am afraid it will be spec., but I don't know all differences. I hope you can help me.
Photos 4-8-2012. in the dunes near Bergen on Achillea. The Netherlands.
Regards,
Thijs

I wouldn't be able to say - the species are too close and even with specimens this is a difficult genus :)
