A very rare and local species in Belgium, mainly in the southern part.
In case the larva feeds on Myrica gale it lives in a neat tube of leaves spun around the stem. On Sanguisorba officinalis it was found in a folded leaf. Pupation in a silken cocoon amongst dead leaves or in the earth or even in a folded leaf (observed in breeding conditions). The imagines hibernate, become active from the evening onwards and come to light.
The hibernating adults fly from late August till early May.
Often Myrica gale is stated as a main host plant. It has also been observed on Salix caprea, Populus alba, and Filipendula ulmaria and other plants. In Belgium a caterpillar was found feeding on Sanguisorba officinalis.
