Xylotrechus cuneipennis, a North-East Asian species occuring in Russia, NE China, Japan, and Korea, has been described from East Siberia as Clytus (Xylotrechus) cuneipennis
by Gustav Kraatz in 1879 [▽]. Larvae of X. cuneipennis develop in trunks or thick shoots of dying and dead deciduous tress (prefer Acer and Carpinus, also in
Quercus, Ulmus, Betula, Alnus etc.). Larvae feed subcortically and later in wood, create galleries filled by fine frass. After the second overwintering they
create a pupal cell in the upper wood layer at the end of the larval gallery. Life-cycle 2 years, adults are active in July and August and can be fouind on dying, uprooted or felled host trees [❖].
