Urania leilus
Urania leilus, the green-banded urania, is a day-flying moth of the family Uraniidae. Although many credit Carl Linnaeus with first describing the species in his 1758 10th edition of "Systema Naturae", Maria Sibylla Merian described the butterfly in her book "Metamorphosis Insectorum Surinamensium", which was published in 1705. It is found in tropical South America east of the Andes, including Suriname, French Guiana, eastern Colombia, Venezuela, eastern Ecuador, Brazil, northern Bolivia, eastern Peru, and Trinidad. It has been recorded as a vagrant to the central and northern Lesser Antilles such as St. Kitts, Barbados and Dominica . The habitat consists of riverbanks in primary and secondary rainforest at elevations between sea level and about . It is sometimes confused with the similar "U. fulgens", but that species is found west of the Andes in South America, Central America and Mexico, is slightly smaller and has less white to the "tail". The two have been treated as conspecific. The wingspan of "U. leilus" is about . As appears to be the case for all "Urania", the larvae of "U. leilus" feed exclusively on species of the toxic spurge "Omphalea".
