This species was mentioned for the first time in Belgium (WV) in 2000. This rare migrant – and perhaps transitory resident – was till 2009 only known for the provinces of WV, OV, HA and AN. After 2009 it was observed throughout Belgium. Nowadays a fairly common species, but mainly in the northern part.
This species hibernates as a larva and pupates in plant debris. The moths come to light.
The adults fly in one generation a year from late June till August and occasionally till late September.
