What is going on with these maples?

[RDAA]

I was at a farmplace where all of the maples (about thirty of them) where the structural branches met the bark was peeling off and I could see about 3/8" holes around those areas every maple had these but the fourty or so ash trees looked fine. I peeled back the loose bark and got some photos of the bugs or whatever they are too. Sorry im really green with this stuffView attachment 243269View attachment 243270View attachment 243271
