Be on the Alert for the Asian Longhorn Beetle

Posted on July 24, 2012

The Ohio Department of Natural Resources’ (ODNR) Urban Forest Division asked Ohio communities to be on the alert for the Asian Longhorn Beetle (ALB). It is the latest invasive species to be found in Ohio.

The ALB is relatively the size of a quarter and potentially very harmful. It is easy to identify because it is colored like a Holstein Cow, white and black, and has long antennae that look like horns.

The ALB is a cousin of the Emerald Ash Borer (EAB) that has destroyed thousands of Ash trees in Ohio. The ALB is potentially more destructive because it will attack any species of tree as opposed to the EAB, which only affects Ash trees.

These beetles especially like Maple, Hackberry and Birch trees, all very common in Lakeside. While the EAB is highly resistant to eradication, the ODNR believes they have learned enough about control, and with early identification, the ALB can be contained.

Similar to most insects, the ALB goes through four stages: egg, larva, pupa and adult. The adult bores holes into the tree and lays eggs. When the eggs hatch, the larvae live inside the tree and plug the xylem and phloem tubes. This process has the same effect on the tree as a human having their veins and arteries plugged.

If the ALB make their way to Lakeside, immediately contact Stephanie Miller, Regional Urban forester of the Ohio Division of Forestry, at (419) 429-8313 or at

Also, please report it to a member of the Tree Advisory Team.
