Biology. Bamboos of the genera Arundinaria (Poaceae) and Pleioblastus (Gramineae) are recorded as host plants in Java and Japan respectively, and rubber wood ( Hevea brasiliensis (Willd. ex A.Juss.) Müll.Arg. ( Euphorbiaceae )) also has been reported associated with this species ( Liu & Geis 2019). It is clearly polyphagous (Beesone & Bhatia 1937; Liu & Geis 2019). In one instance, the beetles emerging from cane bored into bales of yarn together with Dinoderus brevis Horn and D. minutus (F.) causing considerable damage to the yarn ( Beeson & Bhatia 1937).
