Kerria lacca is a species of scale insect known for producing a natural resin called lac. This resin is harvested from the trees where the insects live, primarily in tropical and subtropical regions of Asia. The insects attach themselves to the bark of trees, feeding on the sap and secreting the resin as a protective coating. The lac produced by Kerria lacca is used in various applications, including the manufacture of shellac, a natural varnish and food glaze. It is also utilized in traditional crafts and as a dye. The harvesting process involves collecting the resin from the trees, which is then processed for commercial use.
