The cochineal is a scale insect in the suborder Sternorrhyncha, from which the crimson-coloured natural dye carmine is derived. A primarily sessile parasite native to tropical and subtropical South America and Mexico, this insect lives on cacti in the genus Opuntia, feeding on plant moisture and nutrients.
The insect produces carminic acid that deters predation by other insects. Carminic acid, typically 17–24% of dried insects’ weight, can be extracted from the body and eggs, then mixed with aluminium or calcium salts to make carmine dye, also known as cochineal.1 Carmine is today primarily used as a food colouring and for cosmetics, especially as a lipstick colouring.
