Cactus Insect Dye
Cochineal insects are soft-bodied, flat, oval-shaped scale insects. The females, wingless and about 5 mm (0.20 in) long, cluster on cactus pads. They penetrate the cactus with their beak-like mouthparts and feed on its juices, remaining immobile unless alarmed.
After mating, the fertilised female increases in size and gives birth to tiny nymphs. The Cochineal Cactus Plant, or Opuntia, offers more than its rugged desert beauty. Surprisingly, it serves as the source of a vibrant red dye, thanks to the tiny cochineal insects inhabiting it.

These insects, often confused with red dye beetles, belong to the scale insect family and produce carminic acid, the core ingredient for cochineal dye. Indigenous people in Puebla, Tlaxcala and Oaxaca devised complex systems to cultivate and harvest both the insect and its host cactus to produce the pigment for dyeing fiber, a process that required an in. Cochineal, red dyestuff consisting of the dried, pulverized bodies of certain female scale insects, Dactylopius coccus, of the Coccidae family, cactus-eating insects native to tropical and subtropical America.
Cochineal is used to produce scarlet, crimson, orange, and other tints and to prepare. These are scale insects in the order Hemiptera - the "true bugs," not beetles - that feed primarily on many species of Opuntia cacti, or prickly pears. A dye made of insects helped put the red in Britain's Redcoats.

Cochineal, a tiny, cactus-dwelling insect that produces a vibrant red pigment, was harvested for thousands of years by Indigenous peoples to produce a dye for their own textiles. Following the Spanish invasion of the Americas, cochineal ultimately became a globally traded commodity.

In Europe, its red became the color of power, tinting the red coats of English soldiers and the Catholic clergy. The dye was so much brighter than the rest and almost instantly in high demand in Europe. By 1600, cochineal was second only to silver as the most valuable import from Mexico."

As a rasping, sucking insect, it feeds on the tasty juices of the cactus. The cochineal insect (Dactylopius coccus) and the nopal cactus (Opuntia ficus-indica), also known as prickly pear, form a unique biological partnership. The cochineal insect relies on the nopal cactus for sustenance, while the cactus provides a host environment for the insect's life cycle.
This symbiotic relationship ultimately leads to the production of a vibrant red dye, a substance that. Cochineal insects (Dactylopius coccus) are related to aphids, scale insects and mealy bugs, formerly in the insect order Homoptera. According to evidence from DNA sequencing, they are now placed in the large order Hemiptera with true bugs.
They live on species of prickly-pear cactus (Opuntia), especially the mission prickly-pear (Opuntia ficus-indica), a large, thicket. The present review focuses on the natural carmine red dye extracted from insect Dactylopius coccus. It describes the insect, its infestation and development in the cactus plant, the insect.
