Asian Longhorned Beetle

The Asian longhorned beetle threatens our hardwoods. Learn to spot it and report it.

The Asian Longhorned Beetle (Anoplophora glabripennis, or ALB) is a threat to America's hardwood trees. With no current cure, early identification and eradication are critical to its control. It currently infests areas in Massachusetts, New York and Ohio. It threatens recreation and forest resources valued at billions of dollars. The ALB 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.
