Identify the Asian Longhorned Beetle
The ALB is a destructive pest that kills trees. Learn to identify the ALB, become a Beetle Buster, and help save Chicago’s Trees!

Here’s what to look for:

The Beetle

• Long black antennae with white bands
• Shiny black body
• White spots
• Six legs
• 1 to 1.5 inches long
  You can find ALBs on trees or on objects near trees — check park benches, lampposts, car hoods, and more!

The Trees
The ALB grows and reproduces within hardwood trees, such as:

• Elm
• Horsechestnut
• Maple
• Willow
  

The Lifecycle
The ALB begins life as an egg, hatches into a larva that tunnels into a tree, transforms into a pupa, and then drills its way out of the tree as a mature beetle. The ALB is visible from late spring through fall.

The Evidence
ALBs leave characteristic signs that are easy to identify on trees. Look for sawdust and sap or these beetle signs:

• Round or oval scars on bark
• Dime-sized exit holes
• Yellowing or drooping leaves or dead branches
  

Search this spring, summer, and fall.
