Polygraphus proximus Brandford (Coleoptera: Scolytidae) is a common feeder on Far Eastern firs: Abies nephrolepis, A. hollophyll, and A. sachalinensis. Its native range occupies northeastern China, Korea, Japan, Kurile and Sakhalin Islands, and the southern part of the Russian Far East (Primorskiy and Khabarovskiy Krays). The beetle attacks fresh logs and trees, weakened by fires, pathogens, or defoliation.
