Overview
Opisognathus
*Opisognathus* [auct., verify] is a robust, large-bodied longhorn beetle of the subfamily Prioninae, reaching 20–40 mm in length and characterised by a flattened, predominantly brown to dark colouration. Native to eastern Asia, it inhabits subtropical broadleaf forests from lowlands to approximately 1 500 m altitude in China. Adults are strongly nocturnal and capable fliers, readily attracted to ultraviolet light during their summer flight season from June to September. Larvae develop deep within the heartwood of dead or dying broadleaf trees over a prolonged period of two to five years.
