Asian Longhorned Beetle (ALB)

If You See Something, Say Something
The U.S. Department of Agriculture has issued nationwide warnings about the risk of Asian long-horned beetles (ALB), which are a threat to millions of acres of trees nationwide, including nearly half the trees right here in Valpo. Early detection is crucial in order to keep the ALB from spreading, so if you see something, say something. Call the Indiana DNR hotline at 1-866-NO EXOTIC to report a sighting or visit www.asianlonghornedbeetle.com

Check your Trees
July to October is when the adult ALB is most active, so it's a great time to check your trees. The ALB prefers all varieties of the following species: maple, birch, willow, ash, elm, hackberry, horse chestnut, poplar, London planetree, mountain ash, golden raintree, mimosa, and katsura.

The Asian long-horned beetle has a shiny, jet-black body with random white spots and two long black and white banded antenna. The body is 1-inch to 1-1/2 inches long.

In addition to the insect itself, look for these other signs:
- Dime-sized exit holes in trunk
- Sawdust like material (frass)
- Egg sites in the bark
- Dead or fallen branches

Because there is no treatment for ALB, early detection and eradication is our only defense. By spotting the ALB early, we can stop its spread and protect our trees that provide us with many valuable benefits.
