I took a look at some photos showing cicadia damage, and I think that is
what I have. I wasn't here to see the hatch, but my neighbors said they
were everywhere, so it makes sense that I would have some damage. Most of
my trees are quite small 3 years, but don't think it will kill anything.
At least it is nothing I have to worry about, not for another decade or so
anyway.

Thanks again to all who took the time to help.
