 The moth flies during daytime from June to early August depending on the location.They suck nectar of the preferred blue violet flowers, such as on field scabious ("Knautia arvensis"), dove pincushion flower ("Scabiosa columbaria"), meadow knapweed ("Centaurea jacea"), panicle knapweed ("Centaurea stoebe"), creeping thistle ("Cirsium arvense"), bulbous thistle ("Cirsium tuberosum") and ring thistle ("Carduus").The females lay eggs in July on the underside of leaves of the host plants or on plants that grow close to them.
