Used to be rare and local and mainly observed species in the south of the country, but since about 2010 more and more observations became known from Flanders and the coastal area.
Nowadays a fairly common species throughout Belgium, more observations in the north.
Hibernates as a small larva, low down in the vegetation. Pupates in a cocoon behind bark, among Ivy, in crevices and in loose earth. They rarely come to light but often to sugar. They hide gregariously in dark places during daytime.
The adults fly in one generation a year; from mid June onwards till mid September.
In autum, the larva lives on a variety of herbaceous plants like Rumex, Lamium and Stellaria media. In spring, mainly on shrubs and trees like Hedera, Euonymus, Crataegus, Betula and Prunus spinosa.
