We report that some oedemerid beetles and longicorn beetles visited male flowers of the wild grapevine Vitis ficifolia var. izuinsularis on Miyake Island, off southeastern Honshu Island, Japan. We collected those beetles by beating inflorescences at night, though we had previously found no insects on the inflorescences in the daytime. We also used light traps to collect insects from the vicinity of inflorescences, and trapped many other insect species in addition to oedemerid beetles. Our results suggest that some oedemerid beetles are promising candidates as effective pollinators of the wild grapevine.
