This kite is famous for its silk production. Its scientific name is bombyx mori.
About 3500 B.C. years ago, the Chinese people were familiar with the art of cultivating silk and making cotton from it (the process of raising silkworm and obtaining raw silk from it is called sericulture). It was kept very secret and if anyone tried to steal information about this secret or give information to an unknown person, they would be sentenced to death. But still two monks introduced this art in Europe. The two men came to China as spies, where they learned everything from silkworm rearing to silk-making and took some eggs with them when they went to Europe. Similarly, the process of rearing silk worms in Europe and Africa , India Brunei spread to Thailand

They have sac-like silk glands, which are actually modified salivary glands, through which two narrow ducts open the lower jaw. A caterpillar makes about several thousand meters of silk filaments and up to 1500 centimeters of silk filaments in about a minute.
