The Postman butterfly (Heliconius Melpomene) is a beautiful brightly colored butterfly found throughout Central and South America. The Postman butterfly was one of the first butterfly species observed to forage for pollen, something that is common in other groups but rare in butterflies.
These beautiful butterflies have ultraviolet vision which enhances their ability to distinguish subtle differences between markings on the wings of other butterflies. This helps them know not to mate with other species that share the same geographic range.
