Nopal cactus leafs, infested with cochineal insects, are seen hanging at a greenhouse in Huejotzingo, Mexican state of Puebla September 25, 2014. In the shadow of the massive El Popo volcano, cactus growers in Mexico are helping to revive an ancient dying tradition with the help of a tiny bug that feeds off the country's prickly pears. The humble cochineal insect once occupied a proud place in pre-Hispanic culture as a natural dye for clothes and art. But over the years synthetic colours and the bug's parasitic nature saw it lose favour with local farmers. But amidst worldwide demand for the bug that has come from unlikely sources such as Starbucks and fashionistas, growers of the bug are cashing in. Picture taken September 25, 2014.
