The insect has a metallic green color and is about one-half inch in length. Larvae burrow through an ash tree’s inner layer of bark and it eats away at the vascular tissue that supplies nutrients to the tree. The tree is then expected to die within two to four years. Signs that an ash tree maybe infested with EAB are the canopy dying back beginning from the top downwards, S-shaped feeding lines under dead or splitting bark and a D-shaped exit hole.
