A rare and widespread species in Belgium.
The adults fly from early May towards mid August in one, sometimes two generations a year. They are active from dusk onwards and later come to light. Always observed in the neighbourhood of the food plant.
The monophagous larva lives in the flowers of Digitalis purpurea. Hibernates as pupa, occasionally twice.
