Biology: reared in February from flowerheads of a Centaurea species, which were collected in September of the previous year near Vienna (Austria) by mr. H. Vlug.
I name this species in honour to mr. Vlug, who presented me with numerous interesting Chalcidoidea
Distribution: Austria, France, Greece, Netherlands, Spain, Switzerland.
