Laksha (Lac) – Laccifer Lacca

Lac (also called Laksha) is a slick serum and secretion from a scale insect species Laccifer lacca. These insects suck the sap of several plants and bushes and secrete Lac as a protective covering. Laccifer lacca looks like tiny spots on plants having no limbs and covering with slick serum. Sometimes, these insects are difficult to recognize and we can only see resin excreted by them. Lac scales are main cash crops and are cultured in Burma, India and Thailand. Lac is collected from the plants.
