Genus Urania (Fabricius, 1807) is a genus of black/green metallic diurnal species of Uraniidae moths. Urania moths are known for their large migrations consisting of millions of individuals through Central and South America. Despite that fact however, a few of them appear to be quite restricted and endemic to certain Carribean islands only. There are five to six known species depending on the current taxonomy. Urania moths are specialists that have a very complicated relationship with their food plants: they exclusively use plants from the genus Omphalea as hosts, although they generally use several species of Omphalea.
