Chloridolum viride, an East-Palaearctic taxon occuring in Russian far East, Japan, China and Korea, has been described from East Asia as Leontium viride by James Thomson in 1864 [▽]. Ch. viride, a species inhabiting coniferous and mixed coniferous-broadleaves forests, is polyphagous beetle but in Russian Far East prefers spruce (Picea). Massive reproduction zones of this species have been found in unkept forests containing cut, wind-fallen, and snow-crushed trees. Larvae feed subcortically, the sinuous larval gallery are deeply impressed on sapwood and plugged with fine frass. Mature larvae enter the wood up to 3 cm, create longitudinal gallery there, and do not close it with frass. Pupation (after the second overwintering) in the pupal cell located at the end of the gallery and sealed by small plug of fine frass. Life-cycle 2 years. Adults, active in the second half of summer (July-August), are diurnal and anthophilous [✧].

Body length:14 - 18 mm
Life cycle:2 years
Adults in:July - August
Host plant:polyphagous in both coniferous and deciduous trees, in Russian Far East prefers spruce (Picea)
Distribution:Russian Far East, Japan, China, Korea

Depicted mounted beetle (14.5 mm) was collected in Novo-Aleksandrovsk (Ново-Александровск) environs (Yuzhno-Sakhalinsk, Sakhalin oblast, Far Eastern Federal District, Russia) on June 30, 2013.
