A fairly common species throughout Belgium.
The larva lives mainly on Acer pseudoplatanus and Acer campestre, but has also been observed on Aesculus hippocastanum, Betula and Quercus. Hibernates, sometimes more than once, as a pupa in a double-layered cocoon in a bark crevice or among leaf litter or moss. The adults come to light and sugar.
The adults fly in one generation a year from early May till mid August.
