German. Der Nachweis wird erbracht, daß es sich bei allen britischen Calybites hauderi (Rebel, 1906) um die erste Generation der bivoltinen Caloptilia semifascia (Haworth, 1828) handelt. C. hauderi wird von der britischen Liste gestrichen und das Vorkommen in Belgien wird angezweifelt. C. semifascia ist auf den Britischen Inseln normalerweise univoltin doch breiten sich in den südlichen Grafschaften zunehmend bivoltine Populationen aus.

Evidence is presented that all British specimens of Calybites hauderi (Rebel, 1906) are not that species but the fi rst brood of bivoltine Caloptilia semifascia (Haworth, 1828). C. hauderi is removed from the British list and its occurrence in Belgium is questioned. C. semifascia is normally univoltine in the British Isles but bivoltine populations are now spreading in southern counties.
