Kapuzinerkäfer. Bei der Balz betrillert das Männchen die Flügeldecken des Weibchens. Zur Kopulation dreht sich das Männchen um, so daß die Tiere hintereinander in gegensätzlicher Richtung stehen. Die Eier werden mit der langen Legeröhre in feine Risse in trockenem Holz abgelegt.

Mating of the beetle Bostrychus capucinus can take place when two individuals of the opposite sex meet by chance. If the female is willing to mate, she remains at a standstill and is stroked by the male with feelers and forelegs. During the subsequent pairing the male trills the side tips of the wings of the female and strokes the tip of body at the rear with the palpi. For copulation the male turns and seeks the female sex opening with the tip of his body. Introduction of the aedoeagus (penis) only succeeds when the insects are in a straight line with front sections turned away. Since in this position the male has no contact with the female via antennae or legs, often mating attempts are unsuccessful and the male attempts to introduce the aedoeagus into the females head or side. The eggs are laid in dry wood. The female seeks fine fissures with her long laying duct and lays several eggs each time next to each other.
