Japanese Silkmoth

This is not a butterfly, but rather, a Giant Silkmoth in the family Saturniidae.  Our first matching image in researching its identity was found on Moths and Butterflies of Europe and North Africa where it is identified as a Japanese Oak Silkmoth, Antheraea yamamai, and on SummitPost it states:  “Europe’s largest moth: Japanese Oak Silkmoth (Antheraea yamamai). Its wing span is 11-15 cm.  Originally it lived only in Japan, but it was imported into Europe I think in the middle of the 20th century. A few of them escaped from the farm where they were hosted, and since then it widespread in a few CEE countries, living on oak leaves.”  According to Stock Photo, it was:  “introduced in Europe for silk production.”
