Abstract Geißelspinne. Betrillern der Weibchen bei der Balz und Greifen mit den Palpen, Bildung der Spermatophore, Öffnen der Samenpakete durch das Männchen, Locken des Weibchens über die Spermatophore durch Winken mit den Fühlerbeinen. Aufnahme des Spermas in die weibliche Geschlechtsöffnung.
The film shows courtship and sperm transfer in the large tailless whip scorpion Admetus pumilio from the Amazonas. The courtship display takes several hours during which the male taps the female in a characteristic manner. Occasionally, he steps foreward and grasps at the female with unfolded pedipalps. Finally, the male turns until facing away from the female and produces the spermatophore. This takes about ten minutes. During this time, he keeps contact with the female by alternatingly holding one or the other trembling antenniform leg backwards towards the female. Thereafter he turns towards the female again and, using his chelicerae opens the sperm packages of the spermatophore. Finally, he steps backward, performing beckoning movements with his antenniform legs. The female follows, steps over the spermatophore and picks up the sperm.
