Semanotus bifasciatus, a species occuring in North-East Asia (Russian Far East, North China, Japan, North Korea), has been described from North China as Hylotrupes bifasciatus by Victor Motschulsky in 1875 [▽]. Species inhabits coniferous forests and in Russia is ecologically associated with junipers (Juniperus), but in Japan, Korea and China it also attacks Chamaecyparius, Thuja, and Thujopsis. Adults, active from June through August, can be found on trunks of windfallen or standing dying trees. S. bifasciatus larvae develop under bark of trunks and thick branches of the host trees. Pupation in the pupal cell in sapwood (in depth 2 cm and more, exit/enter hole plugged by frass), life cycle two years [✧].
Body length: 8 - 14 mm Life cycle: 2 years Adults in: June - August Host plant: Juniperus, Chamaecyparius, Thuja, Thujopsis Distribution: Russia, China, Japan, North Korea
