A rather common species throughout Belgium.
The species hibernates in the egg stage.
The larva spins some leaves or flowers together or sometimes even lives in the stem. Larvae can be found feeding within the flowering stems of Petasites hybridus. This causes wilting at the top, which is very similar to the feeding signs of Hydraecia petasitis.
Pupation takes place in a white silken cocoon in the larval habitat.
The adults are mainly active at dusk and later come to light.
The adults fly in two overlapping generations from the end of April till July, and again from end July till the beginning of September.
The very polyphageous larva lives on a variety of plants, mainly in wet habitats: Epilobium, Filipendula, Potentilla, Limonium vulgare and Artemisia maritima, but it has been recorded also from Quercus, Acer pseudoplatanus, Petasites hybridus, Rubus idaeus and even Picea.
