If you have concerns regarding an insect that you've seen or have collected, please note that the emerald ash borer is a very distinct beetle and is often confused with other, more common green beetles in Wisconsin. For comparison, please review these Web sites to see if your sample matches one of them.
If you have concerns about tree damage or suspicious signs or symptoms that your ash tree is displaying, please review these Web sites for additional information.
Finally, EAB infests ONLY ash trees. Please confirm that the tree in question is indeed an ash. Remember, mountain ash or prickly ash are not TRUE ash trees and are not susceptible to EAB.
