 | | Emerald ash borer is an insect native of Asia (eastern Russia, northeastern China, Mongolia, Taiwan, Japan, and Korea), where it can be found on several species of ash and is not considered a pest. |
 | | Common signs of infestation include D-shaped exit holes through the bark about one-eighth of an inch wide, S-shaped larval galleries just beneath the bark, thinning canopy, vertical splits in the bark, and unusual shoots sprouting from the main trunk or base of the tree. |
 | | Ash is one of the most common trees in Ohio, present in every forest type of the state. |
