Mesosa hirsuta has been described from Kobé environs (Japan) by Henry Walter Bates in 1884 [❖]. Its continental subspecies M. hirsuta continentalis, occuring in Russian Far East, Korea, and North China, was described from Seoul environs (Korea) by Masao Hayashi in 1965 [✧]. Larvae of M. hirsuta continentalis feed subcortically in branches and trunks of dying/freshly felled or uprooted deciduous trees, creating in sapwood impressed galleries filled with fine frass. Last instar larvae, after the first overwintering, enter the sapwood where bore pupal cells close to the wood surface. Pupation and hatching of beetles in August-September, young adult beetles leave the host trees and overwinter hidden in the forest litter. They mate and reproduce after maturation feeding on the host trees during the next late spring and summer. Life cycle 2 years [▿].

Body length:8 - 17 mm
Life cycle:2 years
Adults in:May - July
Host plant:polyphagous in deciduous trees (Prunus, Fraxinus, Carpinus, Salix, Quercus, Ulmus etc.)
Distribution:Russian Far East, Korea, China

The depicted female beetle was collected was collected in Vodopadnoe lake environs (N44°27′ E146°06′; Kunashir/Кунаши́р island, Kuril Islands, Yuzhno-Kurilsky district, Sakhalin region, Russia) on August 17, 2013.
