Saperda scalaris hieroglyphica (Pallas, 1773)

Material examined.

Selenge Aimag : 50 km NE of Zuunkharaa (49°05'N, 107°17'E), 930 m a.s.l., 02 VIII 2015, 2 larvae, Betula platyphylla , leg. LK .

Remarks.

Saperda scalaris hieroglyphica is distributed from European Russia to the Far East ( Danilevsky 2017a). This subspecies is sometimes recognised as a synonym of the nominotypical subspecies (e.g., Sama 2002) from which it differs only by its whitish not yellowish pubescence. In Asia, this polyphagous species is ecologically more associated with birch ( Cherepanov 1991b).

Two larvae (Fig. 9G ), which were boring in a thick layer of cambium in a broken trunk of Betula platyphylla (of diameter approx. 20 cm), were found under the bark (Fig. 9H ) in the light taiga habitat (Fig. 7F ). The same material was additionally inhabited by Xylotrechus hircus , Aegomorphus obscurior and Mesosa myops in their immature stages.
