The Asian Longhorned Beetle (Anoplophora glabripennis), is an invasive pest of concern to the U.S. Originally from China, it is also found in areas of Japan and Korea. The first official U.S. identification of Asian Longhorned Beetle was in Brooklyn, New York in 1996 and infestations now exist in parts of New York, New Jersey and Massachusetts. Infestations were eradicated in Illinois and Hudson County, New Jersey.
 
The Asian Long Horned beetle is ¾ to 1 ½ inches long with antennae that are 1 to 2 times its body length.
Adults are shiny black with irregular white spots and the antennae have alternating black and white bands. Adults are active from early summer through mid-fall.  Larvae damage trees by eating away at the outer sapwood, beneath the bark layer, creating hollowed out galleries in the wood.
 
The beetle is a serious threat to hardwood trees and has no known natural predator in the U.S. It threatens urban and suburban shade trees, recreation and forest resources valued at billions of dollars. If the Asian Longhorned Beetle becomes established in the United States, it has the potential to cause more damage than Dutch elm disease, chestnut blight and gypsy moths combined, destroying millions of acres of America's treasured hardwoods, including national forests and backyard trees.
