Emerald Ash Borer Identification

With the ever growing presence of the invasive and destructive Emerald Ash Borer beetle in the Twin Cities many questions are being left unanswered. One major question on most peoples mind is: what does the Emerald Ash Borer beetle look like?

This is a very good question and one that I hope to be able to answer for you in this short article. After all, education is a key element in developing an effective Emerald Ash Borer treatment plan. So lets get started.

The adult Emerald Ash Borer beetle has some very distinct characteristics:

  • the adult beetle has an overall bright, metallic emerald green color
  • the upper side of the abdomen is a very bright coppery red, however this distinct coppery red color will only be visible when the wings are raised
  • the antenna is in a serrated triangular saw like shape
  • between 10 and 13 mm is the general length of the Emerald Ash Borer beetle

The larva stage of the Emerald Ash Borer beetle can be found feeding on the inner bark of you Ash tree. The larva are a white segmented borer that will be identifiable by the S-shaped tunnels they leave on the inner bark of your tree while feeding. The larva will not be as easy to find and see with the naked eye as the adult beetle. This is due to the adult beetle feeding on the outer leaves of your tree while the larva feed on the inner bark of your tree. Meaning, in order to see a larva Emerald Ash Borer beetle you would physically need to remove a portion of the bark to observe the inner portions of your tree.

This is a brief description of the Emerald Ash Borer beetle in it’s adult and larva stage. Of course more information will be needed to develop an effective Emerald Ash Borer treatment plan. There are many helpful resources out there to provide you with more education on the subject of Emerald Ash Borer. For those living in the Twin Cities Metro area I would suggest visiting the Minnesota Department of Agriculture or the City of St. Paul website; as both of these websites provide extensive information on the subject of EAB.
