The emerald ash borer is a half-inch long metallic green beetle with the scientific name Agrilus planipennis Fairmaire. Larvae of this beetle feed under the bark of ash trees. Their feeding eventually girdles and kills branches and entire trees. Emerald ash borer was first identified in North America in southeastern Michigan in 2002.
