Nathrius
Nathrius is a genus of longhorn beetles in the subfamily Cerambycinae, tribe Psebiini. The genus contains three described species, including the widely distributed N. brevipennis, which has been introduced to Australia. Members are small cerambycids with reduced elytra exposing part of the abdomen.
Nathrius brevipennis
Nathrius brevipennis is a small longhorn beetle (Cerambycidae) native to the Palearctic region that has become cosmopolitan through human-mediated transport in timber and wood packaging. Adults measure 4–7 mm in length. The species is polyphagous on dead twigs of broadleaved trees, with documented hosts spanning at least 15 genera including Alnus, Rosa, Fraxinus, Corylus, Ficus, Castanea, Salix, Juglans, Quercus, Morus, Cornus, Ceratonia, Pistacia, Ziziphus, Robinia, and Ostrya. Its invasive spread has led to first records in Australia and other regions outside its native range.
