The Corsican Swallowtail occurs in mountainous areas at altitudes of 2,000 to 4900 feet (609.6-1493.5m) on the islands of Corsica and Sardinia.
The Corsican Swallowtail is mostly black and yellow. Its wingspan measures from 2.8 - 3 inches (72-76 mm). Its wings have a small red eyespot and its tails are small and tapered.
Caterpillars feed on Umberlliferae family such as carrots, and fennel.
The pupae change into adults between May and June and are active until August. The butterfly may generate two broods each year.
The main threat to the survival of the Corsican swallowtail is the loss of its habitats. Another threat are commercial collectors. The Corsican swallowtail is not being protected effectively in Corsica and has no protection in Sardinia. Greater efforts need to be made to save this species.
