The emerald ash borer (Agrilus planipennis), an exotic invasive wood-boring beetle native to Asia, is threatening ash trees throughout North America.
First detected in Michigan in 2002, it is likely this insect arrived more than ten years earlier in solid ash- wood packing materials. Adults have a metallic (brassy or golden) green pronotum, with a darker, metallic emerald green abdomen.
There is potential for extensive negative economic effects if this wood borer were to become widespread in the United States. If left unchecked, emerald ash borer will continue to infest and destroy ash trees, resulting in the losses of millions of dollars to the lumber and nursery industries as well as urban communities.
23 states (or portions of the state) currently have a federal quarantine on emerald ash borer; and 48 states have suitable habitat for the insect
