Overview
Eutetrapha
*Eutetrapha* Bates, 1884 is a small to medium-sized longhorn beetle genus of the tribe Saperdini (Lamiinae), characterised by a robust, cylindrical body densely clothed in cryptic pubescence that helps adults blend against bark. The genus is associated exclusively with oaks (*Quercus*), where larvae develop subcortically and then into the wood over one to three years. Adults are active from May to August, predominantly diurnal, and may be encountered on host stems or beneath bark. The group is distributed across East Asia, with records from Japan and China at altitudes up to 1000 m.
