Description: The wingspan is 24-32 mm for males and 24-34 mm for females.
Biology: The adult butterfly has a jerky and rapid flight that is very similar to a hairstreak, but flies closer to the ground. It is also a strong flyer, borne out by its ability to migrate over large expanses of land and water. This butterfly possesses a pair of "tails" that give this species its name, together with an eye spot where the tails meet the wings. These act to divert a predator, such as a bird, away from the essential body parts. When at rest, the butterfly will rotate the hindwings which causes the tails to move, diverting predators from the more-important parts of the body.
The woodlouse-shaped larva first feeds on the flowers of the foodplant, but eventually enters a pod where it feeds on the contents. This stage lasts between 3 and 4 weeks.
It feeds on the flowers, seeds and pods of many Fabaceae species, including Medicago, Crotalaria, Polygala, Sutherlandia, Dolichos, Cytisus, Spartium and Lathyrus species. It has also been recorded on Crotolaria pallida.
Distribution: Africa, south of Spain, France and Italy, Mediterranean islands and coasts, Turkey, southern Asia until Australia.
In Europe, it is migratory on northern Spain, France, Italy, until Belgium, Netherlands, Switzerland, Germany, rarely Britain.
In Asia, it is also migratory in India.
