Mn: Vörösfenyo szú / En: Large larch bark beetle
5-6 mm. Main host is larch (Larix), occasionally pine (Pinus) and spruce (Picea). The branches of the star-like, multi-branched egg gallery bend irregularly. Both egg gallery and larval tunnels are usually found in the bark. The young beetles feed in younger (1-4 years old) branches. These branches regularly break at the point of attack. The beetles are vectors of a very aggressive pathogen that can cause death of larch trees. European species, occurring sporadically at higher elevations in the Carpathian basin.
