New finding of Thyas juno (Dalman, 1823) (Lepidoptera, Noctuidae) in Transbaikalia

Thyas juno (Dalman, 1823) is a large and bright moth. It there is in the Red Book of the USSR. Its range extends from India and Indonesia in the south to Japan and the southern part of the Far East of Russia in the north, from Sakhalin in the east to the west of the Upper Amur region. Thyas juno was found in the Trans-Baikal region in later years: in Ust-Imalka village in 2005; in Undino-Poselye village in 2014. Th. juno's caterpillar is polyphage of woody plants species so this is species of owlet moth timed to forests. Both Transbaikalia's specimens of Th. juno was found in August and September. It seems that Th. juno don't live permanently in this region. However its ecology should be study in detail in future in Transbaikalia.
