Preparation of Bombyx mandarina
Bombyx mandarina is a butterfly in the true moth family (Bombycidae). It is considered to be the wild form of the silk moth(Bombyx mori).
The moths reach a wingspan of 32 to 45 millimeters. The wings are brown to light brown with light and dark horizontal stripes. The antennae are combed.
The caterpillars reach a length of 35 millimeters and are brown in color. Their front part is colored white. Similar to the caterpillars of the hawkmoths, there is an orange horn on the last segment.
Occurrence and way of life
The moths are distributed in Japan in Hokkaidō, Honshū, Shikoku, Kyushu, Tsushima and Tokara, in China and in South Korea.
The pupation takes place in a cocoon made of silk. In contrast to the domesticated silk moth(Bombyx mori), which is only able to survive in culture and together with Bombyx mandarina forms the entire genus Bombyx, the moth is able to fly and is a widespread species in the wild.
