Common Name: Asian longhorned beetle (ALB)
Scientific Name: Anoplophora glabripennis
Origin: Asia


ALB has a glossy black body with white spots, and adults are 3/4″ to 1″ long. Antennae are roughly 2 times the length of the body and have distinctive black and white bands. Their legs and antennae often have a bluish tinge. Adults are present from July to October.


ALB attacks hardwood trees including maple, birch, horsechestnut, ash, and more, and can survive throughout North America.


Adults feed on leaves and twigs; while larvae feed directly on critical bark layers. Repeated attacks lead to die-back of the tree crown and eventually death.


Management includes quarantines in infested areas, cutting, chipping, burning and ongoing research on insecticides. Prevention includes shipping restrictions and extensive surveys for early detection. Education about using local firewood is also key.

Please report all suspected infestations/observations directly to the DEC. If you think you have ALB, take a picture and email it to DEC ( or call 1-866-702-9938. Keep the suspect beetle in a container in your freezer in case it is ALB. It may need to be sent to a lab for confirmation.


Large, round exit holes (3/8″ to 3/4″ in diameter), presence of frass (sawdust accumulation) and yellowing leaves.
