Papilio hospiton, the Corsican swallowtail, is a species of butterfly in the family Papilionidae. It is found only in Corsica and Sardinia in the Mediterranean Sea.
A medium-sized butterfly with a wingspan of , "Papilio hospiton" is a short black-and-yellow swallowtail with short tails. The butterfly has blue and red markings. Sexes are alike.
"Papilio hospiton" is similar to "Papilio machaon", but the wings are more rounded, and the hindwing is provided with a short tooth instead of a tail. The black colour is more extended and more densely powdered with yellow than in "P. machaon".
The caterpillar is green, striped with black and dotted with small yellowish-red punctures, the black colour being more extended than in the larva of "P. machaon". Chrysalis green, the abdominal tubercles more prominent than in "P. machaon".
The Corsican swallowtail inhabits mountainous regions at above sea level on the islands of Corsica and Sardinia. The food plants are from the family Umbelliferae, and include fennel, giant fennel ("Ferula communis"), Corsican rue ("Ruta corsica") and "Peucedanum paniculatum" though some of these records are disputed. "Papilio hospiton" is bivoltine with broods in May and August. Habitat destruction and disappearance of food plants as well as excessive collecting are the principal threats to the Corsican swallowtail.
