rather common species throughout Belgium.
larva lives on Picea, Juniperus and Pinus. Hibernates as a young larva on the foodplant and pupates in a cocoon.
adults fly in one generation a year; from mid June towards 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.
