Plagionotus christophi, an East-Palaearctic forest species occuring in Russian Far East, China, Japan and Korea, has been described from Amur river valley (Russian far East) as Clytus (Plagionotus) Christophi by Gustav Kraatz in 1879 [▽]. Larvae of this beautiful species develop in lower parts of seriously weakened, dying or freshly dead oaks (mainly of small diameters from 6 to 10 cm). Larvae feed subcortically creating longitudinal, rarely transverse, meandering galleries compactly filled with frass from bark and wood. Galleries have very shallow impression on alburnum and deeper impression in the bark. Mature larvae enter the wood, create the hook-shaped pupal cell (longitudinal to trunk) with exit hole at end, filled with frass. Pupation in late spring after the second overwintering. Adults, active from June to August, can be found on the viable host trees [❖].
Body length: 13 - 16 mm Life cycle: 2 years Adults in: June - August Host plant: oaks (Quercus spp.) Distribution: Russian Far East, China, Japan, Korea
