A rather common species throughout Belgium.
Native
The larva of the summer brood first mines the leaves, and later feeds on the underside of the leaves. The autumn brood larva first leaves the mines, but then enters the stem in which it hibernates. It continues feeding in spring on the buds, flowers and seeds.
Pupation takes places in the seed-head. The larva of the summer generation pupates under a leaf.
The adults are active at dusk and night and come to light.
Two generations a year: June and late July–September.
The larva mainly feeds on Tussilago, possibly also on Petasites.
Ruderal places, wasteland, forest margins.
