The Tobacco Moth (Ephestia elutella), also known as the Cacao Moth or Cocoa Moth, is a stored-product moth in the same genus as the Mediterranean Flour Moth and a significant pest of tobacco products, cocoa, chocolate, nuts, dried fruit, spices, and grain products. Despite its common name, it is rarely a pest of tobacco in household settings — in Arizona homes it is most commonly found infesting chocolate, cocoa powder, nuts, dried fruit, and spices. Adults have a wingspan of about 5/8 inch and are pale gray to brownish-gray with two indistinct pale cross-bands on the forewings — very similar in appearance to the Mediterranean Flour Moth and Almond Moth, making species identification difficult without close examination. Larvae are dirty white to grayish-white caterpillars that spin webbing as they feed. The Tobacco Moth is found worldwide and is a significant pest in food processing and storage facilities. In Arizona homes, it is most commonly introduced through infested chocolate, cocoa, nuts, or spices purchased from stores. Like other Ephestia species, it can complete multiple generations per year in Arizona's warm climate.
