An illustration of Cochineal living on cactus. Cochineal is the name of both crimson or carmine dye and the cochineal insect (Dactylopius coccus), a scale insect in the suborder Sternorrhyncha, from which the dye is derived. This type of insect, a primarily sessile parasite, lives on cacti from the genus Opuntia, feeding on moisture and nutrients in the cacti. The insect produces carminic acid which deters predation by other insects. Carminic acid can be extracted from the insect’s body and eggs to make the dye. Cochineal is primarily used as a food colouring and for cosmetics.
