Answer: Asian longhorned beetles are about 1 to 1-1/2 inches in length, are black and shiny with white spots, and have long antennae that are banded with black and white. They attack many different hardwood trees, including maple, birch, horsechestnut, poplar, willow, elm, ash, and black locust.
The Asian longhorned beetle is a serious threat to hardwood trees and has no known natural predator in the United States. If the Asian longhorned beetle becomes established here, it has the potential to damage such industries as lumber, maple syrup, nursery, commercial fruit, and tourism. So far, quarantine and eradication efforts have confined infestations to Chicago and New York.
If you suspect you have an infestation of the beetle, contact your state's department of agriculture. Make a note of exactly where the insects have been seen and, if possible, contain a specimin in a jar for positive identification.
