This record describes Antheraea yamamai (species). Recorded family: Saturniidae. Recorded order: Lepidoptera.
Identification and Appearance
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...

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Antheraea yamamai. Species-specific details appear above.
Group overview
Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.
Ecological role of the group
Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.
Economic and practical significance of the group
Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
