Emerald Ash Borer (Agrilus planipennis)
Emerald ash borer (EAB) were introduced from Asia in 2002 via infested wood materials. They live exclusively on ash trees (Fraxinus spp.) where larvae feed on the tissue of the tree, and are able to kill it within 2-5 years.
Adult beetles range from 3/8 to 3/4 inches long. Infested trees may exhibit crown dieback (exposing the forest floor to additional light), bark splitting and flaking, D-Shaped EAB exit holes, and epicormic shoots growing off of the trunk. (See images below)
Eradication of EAB is not currently possible, but slowing its spread is imperative. Reducing the transportation of firewood and other ash products can prevent the insect's introduction into new areas.
