What kind of tree is being damaged? Can you send a picture of the damage and of the fly that you're seeing?

The tree before I noticed the damage now and a branch with the holes it was raining when I took damage pics and at night hope the pics help

The best I can tell from your "before" picture is that you possibly have a sugar maple. I recommend that you take pictures during the day and when it isn't raining, From these pictures, the only thing I see is lichen on the bark which is normal for a tree as it ages.
