Saperda interrupta, a beautiful species of montane and submontane coniferous ecosystems of North-East Asia (Russia, Mongolia, North China, Korea), has been described from Siberia by Friedrich August Gebler in 1825 [▽]. S. interrupta larvae develop in both branches and trunks of dying or freshly dead conifers. They feed subcortically, creating sinuous, often broad irregular expanding galleries longitudinal to the trunk, and pack them with coarse fibrous frass. The first overwintering under bark, before the second one larvae enter the sapwood and create in the depth ca 2 cm hook-shaped pupal cell with entry corridor plugged with frass. Pupation and hatching in the next spring. Life-cycle 2 years. Adults, active from June to July, can be found on the host trees where they feed on bark of thin shoots (maturation feeding) [✧].

Body length:7 - 12 mm
Life cycle:2 years
Adults in:June - July
Host plant:polyphagous in coniferous trees (Picea, Abies, Pinus etc.)
Distribution:Russia (Siberia, Far East), Mongolia, North China, Korea
