The largest Central American swallowtail and undoubtedly the precursor species of Papilio homerus, the largest American Papilio restricted to the island of Jamaica.  The female has two forms: a yellow and black form similar to the males (but larger and with blue spots on the hind wing), and a red form with no yellow, as illustrated.  Likes to fly or soar high, and does not keep its wings in motion when feeding on flowers.
