How do I know if my tree has Asian longhorned beetle?
The United States Department of Agriculture (USDA) Forest Service has created the following list of things to look for: • Adult beetles with 1 to 1 1/4 inch-long bodies and 2-inch-long antennae. Their bodies are shiny black with white spots, and their antennae have bands of black and white. • Large (1/2 inch) round holes on the branches of the trunk, created when adult beetles emerge from the tree in the spring and summer. • Round or oval pits in the bark (up to 1/2 inch in diameter), where females chew out a niche to lay their eggs. • Piles of sawdust accumulating at the base of trees or where branches meet the trunk, caused by beetles exiting from inside the trees.
