The Corsican Swallowtail-identification
Papilio Hospiton (Genè 1839)
The Corsican Swallowtail is an endemical species of Sardinia and Corsica and very rare.
This butterfly is similar to Papilio Machaon,distinctive features include the hindwing provided with a short tooth instead of a tail,the red spot at the root of the tail, black basal areas and arches in the discal area of the underside forewings.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.
I observe it every year flying from May to July in my little country of central south Sardinia.
