A rare and local species in Belgium, although it can be common in some years in some places, especially in the south of our country.
They are spinning a shelter among leaves by day.
Hibernates as a pupa, spun into soft bark, sometimes for two or three years.
The adults are active during sunny days.
The adults fly from early March till late April in one generation a year.
The larvae feed mainly on mature: Populus tremula, but sometimes also on Betula or Salix caprea.
