Pseudalosterna elegantula, a species occuring in North-East Asia (Russian Far East, Korea, North China, Japan), has been described from East Siberia (Amur valley) as Grammoptera elegantula by Gustav Kraatz in 1879 [▽]. Larvae of the species develop and pupate in the thick bark of both deciduous and coniferous trees (development in Salix and Abies has been proven). Adults, active from June to August, are diurnal and anthophilous [✧].
