Neocerambyx raddei, a spectacular Cerambycini-tribe species distributed in North-East Asia, has been described from Bureya Massif (Russian Far East) by Constantine Blessig in 1872 [▽]. Species of deciduous forests, its larvae develop in trunks of oaks up to 50 cm in diameter. Larvae feed initially under bark, then in wood, usually make longitudinal galleries. Mature larvae create pupal cells along trunk and pupate in end of June and in July. Adults, which are crepuscular/nocturnal (N. raddei is often attracted by light), are active from July to August [✧]. N. raddei is considered an important oak pest in China.

Body length:32 - 57 mm
Life cycle:at least 3 years
Adults in:July - August
Host plant:polyphagous in deciduous trees (Quercus, Castanea, Morus), but it strongly prefers oaks)
Distribution:Russia (Far East), China, Japan, North Korea, South Korea, North Vietnam

The depicted beetles were attracted by light and collected in Barabash (Барабаш) environs (N43°10′52″ E131°29′21″; Khasansky district, South of Primorsky krai, Far Eastern Federal District, Russia) on July 29, 2020.
