I recently lost a tree, flowering plum, in my front yard. It died suddenly one section at a time. Finally it just went and never grew again. Now, a few weeks ago I ripped the tree out and placed it on the curb but I always wanted to know what killed it. So I went to it's lifeless wooden body laying in the street to give it a little autopsy. I found holes in the trunk, along with splitting along the whole tree. I pulled back the bark and found about 10 of these grubs. Now, I'm not the best at taking pictures but here they go.
