Mn: Betuzoszú  /  En: Eight-toothed spruce bark beetle

4-5 mm. Bivoltine. Main host is spruce (Picea), occasionally pine (Pinus) and larch (Larix). Prefers the thicker-barked stems (4-6 mm). Often occurs together with P. calcographus, partitioning the stem on the basis of thickness of bark. The egg gallery is vertical, regularly two-branched, but can also be single-, or multi-branched. The larval tunnels are dense, emerge at right angles to the egg gallery, and later bend. Eurosiberian species. Undoubtedly the most important bark beetle species in Europe. In the last decade it has been responsible for the death of many millions of m3 of spruce.
