A common species throughout Belgium.
The adults have been observed from late April till the end of July. Most specimens have been seen in May. They fly in late afternoon till dark and later occasionally come to light and sugar.
The larva lives polyphagously on shrubs and trees in a compact tube of spun leaves on Betula, Rubus, Quercus, Larix kaempferi, Pinus contorta ans less often on grasses or herbaceous plants. It hibernates in that tube and pupates in the larval habitation or amongst ground litter.
