This species inhabits the edge of forests, mountain meadows and hot flowery places at an elevation up to 2,700 metres (8,900 ft) above sea level.
This species may have three generations a year. Adults fly from February to early November and are strong migrants. Eggs are white with a greenish tinge and have a disc-shaped form. They can reach a diameter of 0.5 mm. They are laid singly on the flower buds of the host plants.
Old caterpillars are green or reddish-brown, with dark dorsal stripe. They reach a length of 14-15 mm. Pupae reach a length of 9-10 mm. They are light grayish-brown with medium-sized dark spots and dark dorsal stripe.
The larvae feed on flowers, seeds and pods of many Fabaceae species, including Medicago, Crotalaria, Polygala, Sutherlandia, Dolichos, Cytisus, Spartium and Lathyrus species.
