A very rare and local species in the southern part of Belgium, not seen for a long time. Recent observations in NA in 2015 and 2020, afterwards very irregular.
Native
The adults fly in two generations a year; from mid-April till late May and again from late June towards early September.
The larva feeds on herbaceous plants like Solidago virgaurea, Primula veris, Linaria vulgaris, Aster linosyris, etc...
Limestone grasslands where the food plants grow.
