Hi, I had my new house for just one year and i think the maple tree next to my house is having problem. Currently, it has some leaves but certainly far less than some other trees in my yard. My neighbor said it could be dying. I was worried and checked it closely and saw some bugs around some old cuts of the trunk. I cannot tell which type of bugs they are and whether they are harmful. I attached the pictures of one branch with the most leaves (in case it is a different type of tree) and the bugs. Could anyone please tell what they are? Thanks Chris
