In North America, the EAB is an invasive species, highly destructive to ash trees in its introduced range. The damage of this insect rivals that of chestnut blight and Dutch elm disease. [17] For perspective, the number of chestnuts killed by the chestnut blight was around 3.5 billion chestnut trees while there are 3.5 billion ash trees in Ohio ...
The boxelder bug (Boisea trivittata), also called box bug, maple bug or, inaccurately, box beetle, is a species of true bug native to eastern North America.
