Crocidosema plebejana, the cotton tipworm, is a tortrix moth, belonging to tribe Eucosmini of subfamily Olethreutinae. It is found today all over the subtropical and tropical regions of the world and even occurs on many oceanic islands – in Polynesia and Saint Helena for example – but has probably been accidentally introduced to much of its current range by humans. In addition, it is also found in some cooler regions, e.g. in Europe except in the east and north; this is probably also not natural, as it was, for example, not recorded in the British Isles before 1900.
