Het zweefvliegengenus Callicera in Nederland en België (Diptera: Syrphidae)

The syrphid genus Callicera in the Netherlands and Belgium (Diptera: Syrphidae) In Europe six species of Callicera are known. Until recently C. aenea, rufa and fagesii were known from both the Netherlands and Belgium. The authors have studied all available material and have gathered field data. In this paper C. aurata is presented for the first time from the Netherlands. Nine females and one male were observed in south of the province of Limburg. All Belgian specimens of C. aenea proved to be C. aurata (pers. com. L. Verlinden). This means that C. aurata has to be added to the Belgian list and C. aenea has to be eliminated.
