Amarysius

Amarysius

*Amarysius* Fairmaire, 1888 is a small genus of longhorn beetles with a distinctly eastern distribution, ranging across E Siberia, NE China, and Japan. Adults are medium-sized (8–15 mm), typically red-brown, and are associated with flowers of deciduous woodland during the warmer months from May to August. Larvae develop in dead or dying Quercus, progressing from subcortical feeding into the sapwood over one to three years. Despite its interesting ecology and apparent mimicry diversity, the genus remains poorly studied compared to related cerambycine groups.
