Larix decidua
The caterpillars feed on the scales of conifer cones. Host plants are European silver fir ("Abies alba"), European larch ("Larix decidua"), Dahurian larch ("L. gmelinii"), Siberian larch ("L. sibirica"), Norway spruce ("Picea abies"), Siberian spruce ("P. (a.) obovata") and common Douglas-fir ("Pseudotsuga menziesii"). They pupate in peat or rotting wood.
