very rare vagrant in Belgium, not seen every year. There are more
records in the south of the country, especially in the province of
Namur were it is perhaps a transitory resident.
larva is polyphagous and can be found on Quercus and Cistus. In southern Europe it lives mainly on evergreen oak. Hibernates as pupa.
adults have been observed from May till October. They come readily to light.
