A rare species throughout Belgium.
The larva lives from September to May on the food plant. The first instars mine the leaves. Later instars move down and feed on the stems and the roots. They hibernate as a larva.
The adults fly from May till August and come easily to light and they can sometimes be common.
The larva lives on Rumex acetosella, but also on R. obtusifolia (Polygonaceae).
