A very rare and local species in Belgium, only known from old records in the province of LX, possibly extinct now.
The adults fly in one generation a year; from late May towards mid July. They are active from dusk onwards and later come to light.
The larva lives on the flowers and leaves of Solidago canadensis, Artemisia absinthium and Artemisia vulgaris and it demands a very hot microclimate. Hibernates as a pupa, in a tough earthen cocoon usually among surface debris or sometimes underground.
