Description of specimen

My ash tree has tiny bore holes at the base. I saw a shiny emerald bug while working nearby.


Thank you for your report! Can you attach a photo of the holes? Emerald ash borer makes D-shaped holes about 1/8" wide. Here is the address of Oregon Department of Agriculture's IPPM Survey and treatment projects EAB page
