Asian Longhorned Beetle

AboutAsian Long Horned Beetle

The Asian Longhorned Beetle (Anoplophora glabripennis or ALB) is an invasive pest from Asia that came to the United States concealed in solid wood packing material, the pallets, and crates used to transport goods from overseas. The ALB attacks and eventually kills American hardwoods, such as maple, ash, birch, willow, poplar, and elm trees by boring into trunks and branches during its larvae stage. Early detection of infestations and rapid treatment response are crucial to successful eradications of the beetle. Ways you can identify them:

  • Black and white striped antennae, 1 to 3 inches long.
  • Shiny black bodies 1 to 1.5 inches long, with irregular white spots.
  • Leave perfectly round exit holes 3/8-inch in diameter.

Human transport is a prime source of ALB infestation. So it is important to refrain from moving wood out of ALB quarantine areas. If the ALB were to become established here it could be one of the most destructive and costly invasive species ever to enter the United States. It threatens urban and suburban shade trees and recreational and forest resources valued at hundreds of billions of dollars.
