  Pitted Ambrosia Beetle, Maple Corthyle

  Corthylus punctatissimus, commonly known as the pitted ambrosia beetle or maple corthyle, is an ambrosia beetle in the family Curculionidae. It is a documented pest of sugar maple (Acer saccharum) in northeastern North America, with established populations in southern Ontario, southern Quebec, and the Lower Peninsula of Michigan. The beetle targets small-diameter woody saplings and shrubs, boring into stems at soil level and creating spiral gallery tunnels that cause girdling damage and wilting of host trees.
