Graphium is a genus of mostly tropical swallowtail butterflies commonly known as swordtails, kite swallowtails, or ladies. Native to Eurasia, Africa, and Oceania, the genus is represented by over 100 species. Their colouration is as variable as the habitats they frequent; from rainforest to savannah. Some possess tails which may be long and swordlike, while others lack any hindwing extensions. Graphium species are often sighted at mud puddles.
