Invasive Species Awareness Week: Watch for the Asian long horned beetle

Back To Front Page


Gov. Eric Holcomb has proclaimed this week--Feb. 27-March 3--as Invasive Species Awareness Week in Indiana, an important reminder for Hoosiers to watch for potentially devastating pests.

Several invasive species are currently causing significant damage to Indiana’s natural resources, including emerald ash borer, kudzu, hydrilla, and purple loosestrife, according to Megan Abraham, director of the DNR Division of Entomology & Plant Pathology.

“Several more are close enough to our state to cause concern, including the Asian long-horned beetle (ALB) which has been found as close as Cincinnati,” Abraham said in a statement released on Wednesday. “It’s the species like ALB that we have not spotted in Indiana that we need the public to help us watch for.”

ALB attacks hardwood tree species. Maple is its preferred host, however, and is also the most common street tree in Indiana's cities. Signs of ALB start to show about three to four years after infestation. Tree death occurs in 10 to 15 years.

Adult beetles are one to one and a half inches in length, with long antennae banded in black and white and black bodies with small white spots. Adults can be seen from April to December. Look for trees with round exit holes, approximately three-eighths of an inch in diameter, and sawdust-like material at the trunk and branch bases of infested trees.

If you see an ALB or signs of it, call the DNR at (317) 232-4120 with the date and location.

If you can capture the beetle, put it in a plastic jar and put the jar in a freezer to kill the ALB. Carefully wrap the beetle and send it to: Division of Entomology & Plant Pathology; 402 W. Washington Street, Room W290; Indianapolis, IN 46204
