The Eri silkworm, scientifically known as *Samia ricini*, is a species of silkworm primarily found in India and parts of Southeast Asia. Unlike the more commonly known Bombyx mori, which produces traditional silk, the Eri silkworm produces a type of silk called Eri silk, known for its warmth and durability. This silkworm feeds mainly on the leaves of the castor plant and is notable for its ability to thrive in a variety of environmental conditions. Eri silk is often referred to as "peace silk" because the harvesting process does not involve killing the pupae. Instead, the cocoons are collected after the moths have emerged, allowing for a more humane approach to silk production. This makes Eri silk a popular choice for eco-conscious consumers and contributes to sustainable textile practices.
