A rather common species in most areas of Belgium.

The larva feeds on Eupatorium cannabinum. It lives in the stem, usually in the axils of a bunch of flower stalks, making a gall from which frass exudes and causing the flowers to abort. Pupation inside the stem in a short, upward-sloping mine with a partial plug in the entrance.

The adults fly in May-June, and again in July-August. Once, more than 10 specimens were observed at Niel (Antwerpen) in the beginning of April. The adults are active at dusk and come readily to light.
