Amarysius altajensis (Laxmann, 1770)

Material examined.

Selenge Aimag: 50 km NE of Zuunkharaa (49°05'N, 107°17'E), 930 m a.s.l., 02 VIII 2015, 20 larvae, Malus baccata and Prunus padus , leg. LK, MW and WTS ; 40 km NE of Zuunkharaa (48°57'N, 107°05'E), 1270 m a.s.l., 04 VIII 2015, several larvae, (09 II 2016, ex cult), 1♂, from Salix sp., leg. WTS .

Remarks.

This species is distributed from Kazakhstan to the Far East, including northern Mongolia, China, and the Korean peninsula ( Danilevsky 2017a). This forest species inhabits small diameter shoots and twigs of various deciduous plant species. Its life cycle lasts about three years. The imagines fly from May to June and frequently visit flowers ( Švácha and Danilevsky 1988, Cherepanov 1990b).

It seems to be a rather numerous taxon in the Mongolian taiga. Several dozen larvae (Fig. 8A ) were frequently found in shoots and twigs of three deciduous plant species, Malus baccata (Fig. 8B ), Prunus padus (Fig. 8C ) and Salix sp. (Fig. 8D ), in both light and dark taiga. The larvae which were found in Malus wood were definitely more yellowish (Fig. 8E ). In this area, fifteen specimens of A. altajensis were collected by Müller et al. (2013).
