Urania fulgens, the urania swallowtail moth or green page moth,[1] is a day-flying moth of the family Uraniidae.

It is found from Veracruz, Mexico, through Central America to northwestern South America (west of the Andes and south to Ecuador).

[2][3] It is highly migratory and has been recorded as a vagrant to the US state of Texas.

[3] 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".

[2] As appears to be the case for all Urania, the larvae of U. fulgens feed exclusively on the toxic Omphalea species.
