Abstract Die Libelle Tramea legt Eier im freien Wasser ab. Das Männchen führt das Weibchen im Tandem, fliegt auf der Stelle, löst den Klammergriff, das Weibchen taucht das Abdomen ins Wasser und laicht ab. Danach ergreift das Männchen wiederum das Weibchen. Mit Zeitdehnung.
The film shows the North American libelle Tramea l. depositing eggs in tandem. Flying in tandem, separation, the male on guard and the immediate recapture of the female are shown. The film also contains two shots, one in which the female flies away in an upwards direction and the second of a female depositing eggs on its own.
