A rather common species throughout Belgium. Numbers vary much over the years.
Native
Hibernates as a pupa underground. The adults come to light and sugar.
The adults fly in one generation a year: from early May till mid August. Sometimes a partial second generation occurs during September.
The larva lives mainly on Pteridium aquilinum, but also on other ferns, herbaceous plants and even trees.
