A fairly common species throughout Belgium.
The adults fly in one generation a year: onwards from May till early July. They come to light.
The larva feeds inside the seeds of Acer spp. The last instar larva moves to lower parts of the foodplant and spins a cocoon in a crevice or under bark, in which it overwinters.
