Dactylopius is a genus of scale insects, commonly known as cochineals. These small, wingless insects are primarily found on cacti, where they feed on the plant's sap. They are notable for their bright red color, which comes from the carminic acid they produce. This acid is used to create natural dyes, particularly carmine, which is used in cosmetics and food products. Cochineals have been harvested for centuries, especially in Mexico, where they are an important part of traditional dye-making. The insects are collected, dried, and processed to extract the dye. Their cultivation is significant for both economic and cultural reasons, contributing to sustainable practices in dye production.
