Ephestia elutella, the cacao moth, tobacco moth or warehouse moth, is a small moth of the family Pyralidae. It is probably native to Europe, but has been transported widely, even to Australia. A subspecies is E. e. pterogrisella. The wingspan is 14–20 mm. This moth flies throughout the warmer months, e.g. from the end of April to October in Belgium and the Netherlands.

Infestation

The caterpillars of Ephestia elutella are often considered a pest, as they feed on dry plant produce, such as cocoa beans and tobacco, as well as cereals and dried fruit and nuts. Less usual foods include dried-out meat and animal carcasses, specimens in insect collections, and dry wood. Tobacco and its related products can be infested by Lasioderma serricorne (tobacco beetle) and Ephestia elutella, which are the most widespread and damaging parasites to the tobacco industry. Infestation can range from the tobacco cultivated in the fields to the leaves used for manufacturing cigars, cigarillos, cigarettes, etc.
