Xylotrechus pantherinus (Savenius, 1825)

Material examined.

Selenge Aimag : 50 km NE of Zuunkharaa (49°05'N, 107°17'E), 930 m a.s.l., 02 VIII 2015, 1 larva, Salix sp., leg. LK .

Remarks.

This species is widespread in the Palaearctic region and is distributed from western Europe to the Far East ( Danilevsky 2017a). It is monophagous on Salix ( S. caprea in Europe and S. fragilis , S. sibirica and S. xerophila in Siberia). The larvae develop in healthy or weakened trunks and branches, where they feed deep in the wood. Adults can be found on their host plants from June to August ( Cherepanov 1990b, Sama 2002).

A single larva (Fig. 7G ) was found deep in the wood of a standing willow trunk Salix sp. (Fig. 7H ) in the light taiga next to a river.
