The length of the forewings is 17–20 mm. Adults are on wing from June to July in one generation per year.[3]

The larvae feed on various low-growing plants, including Lamium album, Viburnum lantana, Laburnum anagyroides, Prunus spinosa, Lonicera and Ligustrum species. Young larvae live in the top parts of the host plant. The species overwinters in the larval stage. After overwintering, the larvae hide during the day and feed on the terminal part of the twigs during the night. Pupation takes place in the ground.
