Do you know what these moths are (see attached picture) and if they are harmful to my tree? They have been sitting on a maple tree in my front yard all morning, moving slowly around the trunk. I have never seen any like this before. They are about 5 inches across. They seem to be mating and perhaps laying eggs (though I haven't seen any).

This looks like Imperial Moth, Eacles imperialis. The adults do not feed. vw
