Mn: Rézmetszo szú  /  En: Pine bark beetle

2-2.5 mm. Bivoltine. Main host is spruce (Picea), rarely found on other conifers as pine (Pinus), fir (Abies) and larch (Larix). Prefers the thin barked parts of the stem, and is therefore most common on younger trees or on the upper parts of older trees. Polygamous. The egg gallery has 3-9 branches (1 mm wide, and ca. 5 cm long), excavated in the bark, sometimes touching the sapwood. Larval tunnels are dense. Eurosiberian species, common everywhere in the Carpathian basin. In the last decade, together with Ips typographus this species caused serious damage in Hungary.
