The Eri silk moth, scientifically known as *Samia ricini*, is a species of silk-producing moth native to parts of Asia, particularly in India and China. It is known for its unique ability to produce a type of silk called Eri silk, which is soft, warm, and durable. Unlike other silk moths, the Eri silk moth is not killed during the harvesting process, allowing it to complete its life cycle. Eri silk is often used in textiles and clothing, making it popular among artisans and weavers. The moth itself has a distinctive appearance, with a light brown or yellowish body and large, rounded wings. Its larvae feed primarily on the leaves of the castor oil plant, contributing to its ecological role in the environment.
