Discovered new for Belgium in 2009 in some southern limestone areas, where it is local and very rare.
Pupation mostly in the last mine, but sometimes the caterpillar spins some leaves together. The pupa hibernates.
The adults fly in two generations a year: mainly during May and June and again in August.
Bound to warm limestone areas where the foodplants grow.
