Oedecnema gebleri, a beautiful species of North-Euroasian forest zone, is common in Siberia from Urals to Pacific Ocean coast and relatively rare West of Urals. O. gebleri larvae develop in the dead roots of both coniferous and deciduous trees (Quercus, Betula, Salix, Tilia, Prunus, as well as Abies and Pinus). Oviposition occurs at the base of the trunks and the upper sections of the roots, larvae feed initially under bark, then in upper layer of wood, where they make longitudinal galleries and plug them with frass. Adult larvae after the second or third overwintering leave wood and pupate in the soil. If the roots with larvae are barkless, then pupation occurs in the wood. Adults, diurnal and anthophilous, are active from May to August with peak in June-July [▽].
Body length: ♂♂ 11 - 16 mm / ♀♀ 11 - 18 mm Life cycle: 2 - 3 years Adults in: May - August Host plant: polyphagous in a broad spectrum of deciduous and coniferous trees Distribution: Russia, China, Japan, Kazakhstan, Mongolia, North Korea
