Papilio homerus, commonly known as the Homerus swallowtail or Jamaican swallowtail, is the largest butterfly species in the Western Hemisphere.[3] The species is endangered and faces a potentially bleak future.[4] Only two small populations of the Homerus swallowtail remain in a fraction of their original environment. It is endemic to Jamaica where the butterfly simultaneously serves as an icon of national pride and a need for conservation efforts. Over the past half century, the Jamaican swallowtail has been featured on various postal stamps and the Jamaican $1000 bill. In the face of rapid habitat destruction from human disruption and illegal collecting, the Jamaican swallowtail is listed on the Threatened Swallowtail Butterflies of the World by the International Union for Conservation of Nature (Red List) and is protected under international and national level legislation.[4]

The butterfly is named in honor of the Greek poet Homer.[4] The adult butterfly has been described by researchers as “gigantic and magnificent."[5] Females are larger than males and can have a wingspan of 15 cm (6 in).[5] Adults can be seen from morning to afternoon soaring among the canopy of the Neotropical Jamaican rainforests. Its brown-black wings feature a large yellow band and blue and red spotting, making the butterfly easy to spot from far away.[6]

Given the low population and the intense terrain in its forested habitats, few studies of the Jamaican swallowtails have aided to construct a basic biological and ecological understanding of the species. Additionally, very little is known about the swallowtail's behavior. Researchers who study the species all agree that further study is needed to inform and promote an effective conservation strategy for the survival of the butterfly.[6][5][4]
