A very rare and very local species in Belgium. Recently discovered again in 3 provinces after a very long period of absence.
The adults fly in three generations a year; from mid March towards late September. They fly in the late afternoon and from dusk. They are attracted to light.
The larva lives on different species of Galium, especially on G. saxatile. Hibernates as a pupa in a cocoon among plant debris.
