The Asian longhorned beetle, or ALB, is an invasive wood-boring insect that feeds on a
variety of hardwoods including maple, birch, elm, ash, poplar, horse chestnut and
willow, among others. Native to China and Korea, the beetles are approximately 1.5
inches long and shiny black, with white spots on their wing cases. They have black and
white antennae that can be up to twice as long as their body.
