Abstract Taufliege. Balz: Umkreisen des Weibchens und Flügelzittern. Durch Ausstülpen der Genitalien weisen paarungsunwillige Weibchen die Männchen zurück. Aggressives Verhalten der Männchen untereinander: Spreizen der Flügel und plötzliches Stoßen.
The film shows the sexual behaviour of Drosophila lutea. Courtship mainly consists of circling around the female and of wing vibrations. In general, both wings are simultaneously utilized only in the case of vis-à-vis courting. Females unwilling to mate refuse the males by extruding the genitals. While copulating the males display some jerky movements. Against each other, males show an aggressive behaviour characterized by spreading of the wings and by sudden kicking.
