Borer – emerald ash borer

3. Emerald ash borer

Emerald ash borer (EAB) is a highly invasive, non-native insect that attacks and kills all species of North American ash trees, including white, green and black ash. EAB is native to Asia and was first detected in the U.S. in summer 2002 feeding on ash trees in the Detroit area. EAB has not been confirmed in the northern Plains (Kansas, Nebraska, North Dakota and South Dakota).

Adult EABs are emerald green beetles that are approximately 1.5 inches long with slender, elongated bodies. EAB larvae can grow up to 1.25 inches long and are white or cream colored. They have brown heads and a 10-segmented body with a pair of brown, pincher-like appendages on the last segment.
