Kerria lacca is a species of scale insect of the family Kerriidae. It is most well known for secreting lac, a scarlet substance that is used for dyeing wool and silk, as a cosmetic, and as a medicinal drug. Kerria lacca insects inhabit trees in colonies of thousands and secrete the resinous substance.
Kerria lacca excretions can be processed to produce shellac.
