Pseudosieversia rufa, a rare species occuring in Russian Far East, SE China and Korea, has ben described as Pidonia rufa from "East Siberia" by Gustav Kraatz in 1879 [▽]. P. rufa, ecologically associated with Manchurian walnut (Juglans mandshurica) and Manchurian ash (Fraxinus mandshurica), inhabits deciduous forests in lower terraces of river valleys. The larvae develop in the soil on the roots of the host trees, feeding on their bark. Pupation in pupal cells located 4-5 cm below the soil surface, life-cycle two years. Beetles, active from the end of June to August (peak mid-July), are diurnal and very rarely visit flowers. Males often congregate on blades of grass, where they wait for females hatching from the soil and mate with them immediately [✧][❖].

Body length:♂♂ 10.0 - 14.5 mm / ♀♀ 13.5 - 16.0 mm
Life cycle:2 years
Adults in:June - August
Host plant:oligophagous on roots of deciduous trees (Juglans mandshurica, Fraxinus mandshurica)
Distribution:Russia (Far East), SE China and Korea
