A very rare and local species in Belgium.
Hibernates as a fully grown larva and pupates in spring. They come to light.
The adults fly in one generation a year; from early June towards early August. In some years specimens have been seen till mid September.
The larva lives on bracken, especially on Pteridium aquilinum.
