Xanthopastis
Spanish moth
Xanthopastis is a genus of moths in the family Noctuidae, established by Hübner in 1821. The genus contains at least three described species, including Xanthopastis timais, commonly known as the Spanish moth. Members of this genus are notable for their association with ornamental plants and their role as hosts for parasitoid flies. The Spanish moth has been documented as a pest of amaryllis cultivation.
Xanthopastis regnatrix
Spanish moth, convict caterpillar
Xanthopastis regnatrix, commonly known as the Spanish moth or convict caterpillar, is a noctuid moth native to the southeastern United States. The species was previously grouped under Xanthopastis timais, now recognized as a species complex, with X. regnatrix applying specifically to populations in the eastern United States. Its caterpillars are known pests of amaryllis and related ornamental plants. The species has been recorded as far north as coastal New York and Kentucky, though these represent strays outside its core range.
