A very rare and local species in the southern part of Belgium, only found were the food plant occurs.
The larva lives on the leaves of Vincetoxicum hirundinaria and hibernate. The adults can be seen on flowers during twilight and later come to light.
The adults fly in one long extended generation a year onwards from mid April towards August. Very occasionally a partial second generation can occur when conditions are favourable.
