Overview
Nadezhdiana
*Nadezhdiana* Tsherepanov, 1979 is a monotypic cerambycid genus confined to East Siberia, where its single species inhabits riparian and floodplain forests dominated by willow and poplar. Adults measure 6–14 mm and display variable coloration. Larvae develop subcortically before entering sapwood of dead or dying *Salix* and *Populus*, with development spanning one to three years. Adults are active from May to August and may be attracted to fresh dead wood and UV light.
