10 April, moreland in Holland (Gooi), dominated by
Calluna vulgaris. On colony of the bee Andrena vaga (see http://www.corzonneveld.nl/hymenoptera/apidae/Andreninae.php#Andrena vaga), I found this fly.
No Tachinid, although its location certainly suggests it is some kind of (klepto)parasite. Is it Anthomyiidae? And is genus/species ID possible?
Moderately small, say some 6 - 8 mm.
