Overview
Etorofus
Etorofus Matsushita, 1933 is a small boreal genus of longhorn beetles (family Cerambycidae, subfamily Lepturinae) associated with coniferous forests of the eastern Palearctic. Adults, measuring 8–14 mm, are diurnal and frequently observed visiting flowers, particularly of the family Apiaceae. Larvae develop in decaying wood of Picea and Abies over a prolonged period of two to four years. The genus is restricted to Japan, including Hokkaido and the Kuril Islands, inhabiting forests from lowlands up to 1000 m altitude.
