I have found dozens of skeletons on the trunk of my shamel ash trees - they look beetle like my husband says.  I also see several holes in my lawn near these trees they look like someone stuck a thin pole in the ground and left a bunch of holes.  Do you know what type of pest this might be and do I need to worry about my trees or lawn?

Thanks for any help you can provide.
