Urania swallowtail moth
Urania fulgens
''Urania fulgens'', the urania swallowtail moth, is a day-flying moth of the Uraniidae family. It is found from Veracruz, Mexico, through Central America to northwestern South America . It is highly migratory and has been recorded as a vagrant to Texas, USA.
It is sometimes confused with the similar ''U. leilus'', but that species is found east of the Andes in South America, is slightly larger, and has more white to the "tail". The two have been treated as conspecific.
As appears to be the case for all ''Urania'', the larvae of ''U. fulgens'' feed exclusively on the toxic ''Omphalea'' species.
