Antheraea yamamai japanese oak silkmoth
The Japanese silk moth or Japanese oak silkmoth (Antheraea yamamai, Japanese: Yamamayu(ga) (山繭(蛾)・ヤママユ(ガ)) or tensan (天蚕)) is a moth of the Saturniidae family. It is endemic to east Asia, but has been imported to Europe for Tussar silk production and is now found in South-Eastern Europe, mainly in Austria, North-Eastern Italy and the Balkan. It seems to be spreading north and a population near Deggendorf and Passau (Bayern) has been reported. It has been hybridized artificially with Antheraea polyphemus of North America.
