Lac beetles (Kerria lacca) are insects that are native to India and Southeast Asia. They are small beetles that measure about 6-8mm in length. Lac beetles are known for producing a resin called "lac," which is used in a variety of products including shellac, varnish, and sealing wax.
Lac beetles feed on tree sap and secrete the resin as a protective coating for their eggs. The resin hardens and forms a cocoon-like structure around the eggs, which is known as "lac stick." The lac stick can be harvested and processed to extract the lac resin, which is then used in various products.
Lac beetles are also known for their bright red and yellow coloration, which makes them attractive to collectors. They are often kept as pets or used in traditional medicine in some parts of Asia.
