A rather common species throughout Belgium.
Hibernates as a young larva on the food plant and pupates in a cocoon.
The adults fly in one generation a year: from mid June till mid August.
Occasionally some specimens can be observed during September and October, but it's not clear yet if this could be a partial second generation or just an occasionally protracted first generation.
They come to light.
The larva lives on: Picea, Juniperus or Pinus.
