(Coleoptera: Cerambycidae: Lamiinae: Onciderini)

Abstract - Branch girdling, copulation and oviposition of O. germari (Coleoptera: Cerambycidae) are described and illustrated. The oviposition comprises three successive steps, each dependent from the preceding one: search for an appropriate place, making of the egg-notch and oviposition proper. Different ovipositions may be successive. The girdling of the branch is independent from this sequence, it does not precede oviposition and may actually be suppressed in some females. Copulation overlaps with the time range of branch girdling, feeding and the first two steps of oviposition. Different behaviour categories of males and females are established.
