Economic/Human Considerations

Adults feed on the bark of softwood seedlings creating irregular-shaped scars along the stem. If 50% or more of the bark is removed, the seedling will likely die. Feeding damage also creates a wound allowing disease to enter the tree. http://tidcf.nrcan.gc.ca/insects/factsheet/1720
