Hibernates as a pupa in a tough cocoon among plant debris. The adults are active during the day and later come to light.
The adults fly in two generations a year from mid-April to late August.
The larva lives on the flowers and leaves of Polygala vulgaris, Polygala serpyllifolia and Pedicularis sylvatica.
It inhabits nutrient-poor grasslands.
