This very rare xerothermic species was discovered for the first time in Belgium in August 2007 in the most southern part of LX. It was one of the few species to be expected, because there are some small isolated populations in France not far from the Belgian border. It is widely distributed in southern Europe. Second observation was during 2016 at the coast at Koksijde.
Nowadays only a few observations are known.
Both observations to date were during May and August, it's not known of this were migrants or represents a small population. The nearest populations fly in one or two generations a year; during June and July and during August and September. Occasionally disturbed by day but usually seen at light.
The polyphagous larva lives on various herbaceous plants, preferring dry and withered parts. Recorded on many plants, such as Convolvulus, Scabiosa, Veronica, Frangula, Galium, Rubus, Stellaria, Rumex, Plantago etc... Hibernates as a larva and pupates in loose earth.
