Zur Brutbiologie von Saperda similis Laicharting 1784 (Coleoptera: Cerambycidae)

Abstract

At a right angle to the longitudinal axis of willow branches (Salix caprea L) of at least 2 cm in diameter Saperda similis Laicharting 1784 gnaws a series of egg niches into the bark. By this an incision of until 4 cm with about 12 eggs is resulting. After having completed each single niche a single egg is deposited. Eggs of one series are often deposited alternatively from the right and the left side. The longitudinal incision bestows a greater dilatability to the bark and serves by this as shelter to eggs and young larvae against the exuberantly growing wound callus.
