We have what appears to be a Beetle infestation at the base of an Ash tree. We've seen a couple beetles coming and going, but not sure if they are the cause, or just traveling the tunnels. Our ultimate concern is if they will damage the tree, and what type of beetle it is. I've attached pictures of the tree base (same thing around surface roots), one beetle carcass at the base, and one live beetle seen today. They seem to be about an inch to inch and a half long, black, with a short horn. Thanks for your help. Bill M.
