A very rare migrant in Belgium.
Since 2020 there has been a small stable population around Tongeren (LI). From 2022 onwards, more and more sightings became known from LI but also elsewhere in the country.
Data Deficient due to a lack of sufficient data according to the IUCN Red List category for Flanders 2023.
Migrant
Overwinters as a caterpillar and pupates around May.
The adults fly from late June to mid-August.
