The Almond Moth (Cadra cautella), also known as the Tropical Warehouse Moth, is a stored-product moth closely related to the Mediterranean Flour Moth and a significant pest of nuts, dried fruits, chocolate, cocoa, and grain products. It is particularly well-adapted to warm climates and thrives in Arizona's desert heat, making it a more significant pest in the state than in cooler regions of the country. Adults have a wingspan of about 5/8 inch and are gray to brownish-gray with indistinct darker banding on the forewings — similar to the Mediterranean Flour Moth but generally darker and less distinctly patterned. The hindwings are pale gray. Larvae are dirty white to pinkish-white caterpillars that feed on a wide range of stored products including almonds, walnuts, pecans, peanuts, dried figs, dates, raisins, chocolate, cocoa powder, flour, and grain products. In Arizona, the Almond Moth is a particular concern in homes that store large quantities of nuts or dried fruit, and in commercial facilities handling these products. Like other stored-product moths, larvae spin webbing as they feed. The Almond Moth can complete a generation in as little as 5 weeks in Arizona's warm conditions, allowing rapid population buildup.
