distribution and habitat
The gray wood owl occurs locally in northern and central Europe. In Siberia , Japan and Korea that is a subspecies Lithophanes consocia grisea ( Grasses , 1889) at home. The species occurs in open tundra and taiga areas as well as in shrubby terrain, montane stream valleys, swampy forests and in the hill country.
Way of life
The moths fly in one generation from September to November, overwinter and then live from March to May of the following year. They are nocturnal and visit artificial light sources and bait . They were also observed drinking tree sap or sucking on flowers. The caterpillars live mostly from May to July. In Finland they feed exclusively, in the rest of Fennoscandinavia mainly on the leaves of the gray alder ( Alnus incana ). Sometimes other types of alder ( Alnus ) or hazelnut ( Corylus ) are also accepted as food.
