A rare and widespread species in Belgium.
The adults fly in one generation a year; onwards from mid May towards mid July. They come to light.
The larva feeds internally in the cones of conifers like Abies procera, Picea abies and Picea sitchensis. The trees must be sufficiently mature as to produce large numbers of cones. Hibernates as a pupa in a flimsy cocoon among fallen conifer needles or other plant debris on the ground.
