Chlorophorus simillimus, a North-East Asian species occuring in Russian Far East, NE China, Japan, Korea, and Mongolia has been described from Amur River Valley as Clytus sexmaculatus by Victor Ivanovitsch Motschulsky in 1859 [▽]. However, due to preooccupation, the valid name of this species is Chlorophorus simillimus proposed by Gustav Kraatz in 1879 [✧]. Larvae of this species develop in branches and trunks of dying or freshly dead deciduous trees, creating longitudinal meandering galleries in the sapwood compactly filled with fine frass. After the second overwintering larvae create pupal cells in sapwood with premade exit corridors up to bark filled by frass. Pupation in May-June, life-cycle 2 years. Adults, active from June to August, are diurnal and anthophilous (can be found on Spiraea, Asteraceae, Apiaceae...) [❖].

Body length:9 - 17 mm
Life cycle:2 years
Adults in:June - August
Host plant:polyphagous in deciduous trees (Crataegus, Acer, Juglans, Prunus, Pyrus, Rosa, etc.)
Distribution:Russia (East Siberia, Far East), NE China, Japan, and Korea

The depicted female beetle was collected in Lazo outpost (Лазо́) village environs (Lazovsky District, Primorsky Krai, Far Eastern Federal District, Russia) on June 19-20, 2010.
