A local and very rare species in Belgium, mainly observed in the southern part.
The adults fly in June and July. They are active at dusk and come to light
The larva feeds in a gallery or web, spinning the flowers and seeds to the main stalk on Rhinanthus, Melampyrum pratense, Solidago virgaurea or Pedicularis. It hibernates in its cocoon and pupates in a tough semitransparent cocoon.
