This bark-beetle is locally distributed over the forested areas of Quebec and Ontario, extending westward into Manitoba; in the United States, it has been recorded from Wisconsin and Michigan.
The insect has been found breeding in fallen white pine and jack pine, and, within recent years, has also been recorded from red pine.
