Kerria lacca is a species of scale insect known for producing a natural resin called lac. This resin is harvested from the branches of certain trees, primarily in tropical regions of Asia, where the insect thrives. The process of collecting lac involves scraping it off the tree bark, and it is then processed into various products. The resin from Kerria lacca is used to make shellac, a versatile material used in woodworking, food glazing, and cosmetics. Shellac is valued for its durability and glossy finish, making it a popular choice in many industries. Additionally, the insect plays a crucial role in the ecosystem by contributing to the health of the trees it inhabits.
