Phymatodes (Poecilium) maaki, a beautiful small Cerambycid inhabiting southern part of the East-Asian deciduous forests, has been described as Callidium Maaki from the Russian Far East by Gustav
Kraatz in 1879 [✮]. Its insular subspecies, occuring in the Kuril Islands and Japan, has been described by Mikhail L. Danilevsky in 1988 [✳].
Ph. maaki larvae fevelop in dying/freshly dead grapevine twigs. Young larvae create longitudinal subcortical galleries deeply impressed in wood densely filled with fine frass.
Mature larvae later penetrate deeper into sapwood and create there pupal cells. Adults are active from late May to early June. Beetles, which never visit flowers, can be found on the host plant [❖].
