A rare species in Belgium.

The larvae feed usually on Artemisia vulgaris, less frequently on A. campestris. Initially starts as a long gallery which follows a vein or the margin of the leaf and becoming an upper surface blotch. Pupation external in a dull ochreous cocoon spun on leaf litter.

The adults fly in two generations a year; during May and August. They are active in late afternoon and later come to light.
