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 caterpillars 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 includedried-out meat and animal carcasses, specimens in insect collections, and dry wood.
