Eustrangalis distenioides, a striking Cerambycid species occuring in the Kuril Islands (Kunashir) and Japan, has been described from Japan (Honshu) by Henry Walter Bates in 1884 [▽]. E. distenioides larvae develop in the dead, but still solid wood of deciduous trees. In Kunashir, only Kalopanax septemlobus is the host tree, but the species is not monophagous, as it is reported from Japan from other Araliaceae, and also from maples (Acer spp.). Larvae pupate in late summer and young beetles overwinter, life-cycle two or three years. Adults, active from June to August, are diurnal and anthophilous [❖][✧].

Body length:♂♂ 13 - 16 mm / ♀♀ 15 - 20 mm
Life cycle:2 - 3 years
Adults in:June - August
Host plant:polyphagous in deciduous trees
Distribution:Russian Far East (Kuril Islands - Kunashir), Japan

The depicted male beetle (16 mm) was collected in the Ecological trail "Stolbovskaya" / Stolbovskiye springs (Источники Столбовские) environs (N44°00′26″ E145°40′59″; Kunashir/Кунаши́р island, Kuril Islands, Yuzhno-Kurilsky district, Sakhalin region, Russia) on July 21, 2013.
