| The Emerald Ash Borer (EAB) is an exotic beetle that was discovered in southeastern Michigan in 2002. The adult EAB nibbles on Ash foliage and causes little damage. The larvae however, feed on the inner bark of Ash trees, disrupting the tree's ability to transport water and nutrients. |

The EAB most likely was transported to the US from a cargo ship or airplane in the 1990's from their native habitat, Asia. | |
| • |
It was first discovered in Windsor, Ontario and the Detroit area in 2002. | |
• |
The EAB was found in Ohio in 2003, northern Indiana in 2004, and northern Illinois in 2006. | |

• |
The average length for an adult EAB is 3/4 in. long and 1/6 in. wide. |  |
• |
Larvae reach a length of 26-32mm long and are a beige color. | |

The color of the larvae makes it very difficult to spot on a tree. The eggs turn to a yellow brown color prior to hatching. | |

The emerging season for the emerald ash borer is early spring to late summer. Females lay around 75 eggs from early May to mid-July. |  |
