Due to the heavy brush cover, we could only get to this area of the property during the winter months. Now that the snow is letting up, it is a good time to do some tree work. While removing a dying tree we had believed was stressed from oriental bittersweet, we discovered it was riddled with holes on all sides.
While the sheer number of holes and the speed at which this infestation killed this tree is a cause for concern. The holes are not D shaped like I would expect if this was EAB (a characteristic marker).
Every photo I've seen of EAB grubs show them as being skinnier and with more distinct segments. These grubs were pretty stocky by comparison, so I don't think they are EAB grubs. It was difficult to photograph cleanly, but the galleries didn't look s-shaped, another characteristic of EAB. At best, they were "c-shaped".
I am also unsure if this is an ash tree (it has mostly been a kickstand for massive multi flora rose bushes and bittersweet). I was never that good at dendrology, so I can't tell what species the tree is without leaves... The bark looks like it's a little ash-ey to me, so I'm not confident saying that this is NOT an ash. EAB needs ash as a host, so I would appreciate some help identifying this tree.
