Abstract
Zur Kopulation suchen die Buchdruckerweibchen die Rammelkammer auf. Vor der Kopulation betrillert das Männchen den Hinterleib des Weibchens. Die Weibchen legen die Einischen seitwärts am Ende der Muttergänge an. Am Ende dieser Gänge werden Krümel bereitgelegt, mit denen die Nischen jeweils nach Ablage eines Eies verschlossen werden.
In the mating chamber the typographus male copulates twice with a female. Copulation is initiated by either male or female. The mates separate 10-30 seconds after the union. The egg-laying behaviour of the female is shown in 3 examples. The female always gnaws the new egg-niche at the end of the gallery. Mandibles and maxillae form a functional unit for gnawing. To lay the egg, the female backs up to the niche and lays egg directly into it. Afterwards she closes the niche with crumbs of phloem which she has already placed at the end of the gallery for this purpose.
