What does cochineal mean?
Cochineal is a natural red dye made from the dried bodies of a small scale insect of the same name, which lives on prickly pear cacti in Mexico and Central and South America. The word refers both to the insect itself and, more commonly, to the intense crimson colouring extracted from it, long used for dyeing textiles and now found in foods, beverages, lipsticks, and other cosmetics, frequently listed on labels as carmine or E120. Prized by the Aztecs and Maya before becoming one of Spain's most lucrative colonial exports, cochineal was once worth nearly its weight in gold in European markets. Although synthetic dyes have displaced much of its use, demand persists among producers seeking natural colourings. The term carries connotations of rich, deep red and appears chiefly in scientific, historical, and culinary-labelling contexts.
A brilliant red dye prepared from the dried bodies of cochineal insects, used especially in food, cosmetics, and textile dyeing.
"The dyer steeped the wool in a bath of cochineal until it glowed deep crimson."
In commercial contexts the purified extract is usually called carmine and labelled E120.
The scale insect Dactylopius coccus, native to tropical and subtropical America, which feeds on prickly pear cacti and yields the dye when dried and processed.
"Farmers carefully brush the white-coated cochineal from the cactus pads before drying them in the sun."
When referring to multiple insects, 'cochineals' is standard; the dye itself, like most substances, is typically used uncounted.
"She raised cochineals on rows of potted prickly pears behind the workshop."
That bright red in your strawberry yoghurt or lipstick may come from millions of tiny crushed insects — cochineal has coloured food, cloth, and cosmetics for centuries.

Etymology of cochineal
Cochineal entered English in the late sixteenth or early seventeenth century from French cochenille, borrowed from Spanish cochinilla, a diminutive form ultimately derived from Latin coccinus, meaning 'scarlet'. The Latin word traces back further to Greek kokkos, meaning 'berry' or 'grain', a reference to the kermes insect once mistaken for a plant gall. It thus shares a distant root with related dye-words such as kermes, and through the same Mediterranean trade vocabulary connects with carmine and crimson, both of which derive from the Arabic name for the kermes dye.
How cochineal is actually used
Register is neutral to slightly technical; the word appears mainly in contexts of dyes, food labelling, history, and entomology. In ingredient lists it may appear as 'cochineal', 'carmine', or 'E120'.
Easily confused with cochineal
Cochineal is the insect (and loosely its dye), while carmine specifically denotes the purified red pigment or colouring extracted from those insects.
