From the Morristown Shade Tree Commission:
The Emerald Ash Borer has found its way to New Jersey.
This is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002.
The larvae feed on the inner bark of ash trees, disrupting the trees’ ability to transport water and nutrients, thus killing the tree.
Tens of millions of ash trees in SE Michigan have been destroyed with tens of millions more lost in Colorado, Connecticut, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Massachusetts, Maryland, Minnesota, Missouri, New Hampshire, New York, North Carolina, Ohio, Ontario, Pennsylvania, Tennessee, Quebec, Virginia, West Virginia, and Wisconsin.
What to look for:
- It attacks only ash trees
- Adult Beetles are metallic green and about 1/2-inch long.
- Adults leave a D-shaped exit hole in the bark when they emerge in spring
- Woodpeckers like EAB larvae; heavy woodpecker damage on ash trees may be a sign of infestation.
