Acalolepta luxuriosa, a North-East Asian species occuring in Russian Far East, Japan, Korean peninsula and North China, has been described from Japan (Nagasaki environs)
as Monohammus luxuriosus by Henry Walter Bates in 1873 [▽].
A. luxuriosa, inhabiting North-East Asian deciduous forest zone, is polyphagous species attacking deciduous trees (known only from Kalopanax septemlobum and Aralia elata
in Kunashir). Its larvae develop in trunks of dying or freshly dead trees. Youg larvae feed subcortically, creating in sapwood slightly impressed galleries filled with fine frass.
Later instars enter the wood and bore gallery finished by pupal cell (after the second overwintering) where they also pupate. Life cycle 2 years. Adults, active from July to August, can be found
on the host trees [✧].
