The Lymantria Dispar, also known as the Flighted Spongy Moth Complex (FSMC), formerly known as the Asian Gypsy Moth, is a species of moths, native to China, far-East Russia, and other countries of the Asia-Pacific, such as Japan and Korea.
Spongy refers to the characteristic of the moth eggs which resemble a sponge-like mass. FSMC is a highly destructive pest posing a severe biosecurity risk. If transferred to non-native locations, the FSMC population is also less likely to encounter limitations imposed by natural barriers, such as predators, parasites, viruses, and competing species.
