A rare species in Belgium, mainly observed in the Kempen region and the southern part of the country.
The adults fly in July and August. They are active at dusk and later come to light.
The larva lives in a slight silken tube spun on the underside of a twig of Prunus spinosa, also on Crataegus or Sorbus. Pupation takes places inside the tube.
