NOTE: Only one species in this Neotropical group has been recorded in the US (as a stray); however, several species are popular attractions in butterfly houses. This Genus and the taxonomic arrangement within it is incomplete. Many internet and published references contain erroneous id's and distributions. Currently, the "Butterflies of America" site is the best on-line resource for this Genus (Although there may be some id errors ... these discrepancies are based on the original identifications within museum holdings and not likely those of the persons constructing and overseeing this site).
