A very rare immigrant in Belgium. During very warm years the species can be resident for some time.
The adults fly in two to four generations a year. Observations onwards from mid April towards early October. They come to light.
The larva feeds in buds, leaves of fruits on a variety of shrubs and trees like Ligustrum vulgare, Berberis vulgaris, Clematis, Lonicera, Cornus, Hedera, Crataegus etc... In the southern part of Europe it's a serious pest of Vitis vinifera. Hibernates as a pupa in a weak cocoon.
