A rare species in Belgium, mainly observed in the northern part.
The adults fly in one generation a year; from June till August. They are active from dusk onwards and later come sparsely to light.
The larva lives on the flowers and seedheads of Artemisia absinthium, also on Artemisia vulgaris. Hibernates as a pupa, in a tough cocoon of silk and earth, usually among surface debris but sometimes underground.
