Fig. 5B, C

Literature data. Ömnögovi: Noyon mountains [горы Ноён], 14 km S of Noyon [Ноён] [43.020, 102.127], 23.08.1969, 2 exx., 1 ex., on Amygdalus ( Namhaidorzh 1972) .

Remarks. Polyzonus fasciatus is widely distributed in SE Palaearctic (most of the territory of China and the Korean Peninsula) ( Danilevsky 2020), however it is rather sporadic in northern Asia (including northern Mongolia) ( Cherepanov 1990a).

In northern Asia, the species inhabits forest-steppe zone and is ecologically associated with Rosa L. ( Rosaceae ). Adults are active from the end of June to the last days of September and they require supplementary feeding, which is held on plants of Rosales , Apiaceae , Asteraceae and some others. Larvae feed in viable shoots of different roses ( Rosa acicularis Lindl. , Rosa maximowicziana Regel , Rosa rugosa Thunb. ) that usually grow in well-warmed soil. Cherepanov (1990a) reported the case of one larva developing on each inhabited shoot, which leads to damage of basal section of shoots.

The depicted pair comes from the collection of USMB and was collected in northern Mongolia.
