Remarks.

Xylotrechus adspersus is distributed from Altai to Sakhalin and Japan and from Yakutia to northern China and the northern part of the Korean Peninsula ( Cherepanov 1990b, Danilevsky 2018a). The species is ecologically associated with willows and Chosenia arbutifolia . After mating, the females lay their eggs in living twigs. The larvae initially live under the bark and then in wood where they pupate after about two years. The imagines usually emerge from June to July ( Cherepanov 1990b, Danilevskaya et al. 2009).

Several specimens were collected in the Putintsevo environs in June 2005 by Danilevskaya et al. (2009).

A single, probably freshly emerged, female was observed sitting motionlessly on a willow branch next to its emergence hole in an enclave of willows located next to a river (Fig. 12A). Moreover, several fresh larval feeding galleries of this species (Fig. 12B) were found in willow branches that were still alive, together with a single early instar larva under bark. Additionally, a few imagines of an unidentified parasitic Hymenoptera species were found in tunnels.
