A robust beetle, 3.8–6.0 mm long when adult, that parasitizes (see parasitism) coniferous trees, especially larch (Larix species), Scots pine (Pinus sylvestris), Norway spruce (Picea abies), and fir (Abies species). It occurs throughout southern and central Europe, Siberia, Korea, Japan, and Taiwan. The male beetle excavates a nuptial chamber in which mating occurs; larvae feed and pupate in the bark and sapwood. It was first recorded in Britain in 1955, at 29 localities in Moray, Nairn, Banff, and Inverness, Scotland.
