I have another picture which is less sharp, but with a different angle of view. mariki attached the following image: [139.1Kb]

However, the moderate prac, the convex scutum and pale calypters should be enough to separate this species from Protocalliphora and Protophormia. So, I'm convinced it is Phormia regina, but I can't prove it. Stephane.

It seems that the distance is larger for the two first species. I do not know if there are other look-alike species in Belgium.
