A very common species throughout Belgium. One of the commonest members of the genus.
The adults fly from mid May till mid September. They are active from dusk onwards and later come to light.
The larva feeds between spun leaves or in a rolled leaf on Urtica, or, less frequently, Marrubium, Stachys spp., Mentha spp., Ballota or Convolvulus. It hibernates in its cocoon. Pupation takes place in a cocoon spun under loose bark, deep in debris, etc.
