Dactylopius coccus
The cochineal (/kɒtʃɨˈniːl/ koch-i-neel or /ˈkɒtʃɨniːl/ koch-i-neel; Dactylopius coccus) is a scale insect in the suborder Sternorrhyncha, from which the crimson-coloured dye carmine is derived. A primarily sessile parasite native to tropical and subtropical South America and Mexico, this insect lives on cacti from the genus Opuntia, feeding on plant moisture and nutrients.
This scale lives on Opuntia (pad) cacti.
When you touch the white fuzz, it turns into beautiful purple fluid (see second picture). The Aztec used this as a dye for the clothing of the most powerful members of the society, and after the conquest (holocaust) of South America, it was harvested and sent to Europe for use as a dye there.
