A very rare species, mainly in the south of Belgium.
For the time being, it is still uncertain whether this species will still occur after 2004 due to a lack of convincing criteria (photographs), although the species occurs in France very close to the Gaume.
This species is considered Regionally Extinct according to the IUCN Red List category for Flanders 2023.
Native
Hibernation in the pupal stage.
The adults fly from May towards early August.
The larva feeds on Dipsacaceae such as Knautia arvensis.
It prefers nutrient-poor meadows, preferably along forest edges. Also on gappy, stony and eroded slopes near forests.
