A rare and widespread species in Belgium.
The larva lives on the buds and flowers. Hibernates as pupa in a cocoon among plant debris. The adults come to light.
The adults fly from early May till July, sometimes till August. Frequently fresh specimens are trapped during October. Whether this are very late specimens or individuals of a partial second generation is unknown. In the literature is only one generation a year mentioned.
The larva lives on Clematis vitalba, also on cultivated plants.
