Lac insects, Lac scales
Kerriidae is a family of scale insects in the order Hemiptera, commonly known as lac insects or lac scales. Members secrete a protective waxy resin called lac, which is commercially harvested and processed into shellac, dyes, food glazes, and wood finishes. The family includes economically important genera such as Kerria, Tachardina, and Paratachardina, with Kerria lacca being the most widely cultivated species for lac production. Some species have become invasive pests outside their native ranges, while others are valued for their role in sustainable agroecosystems.
