Tent caterpillars can do quite a number on tree foliage but that is very survivable compared to what the emerald ash borer can do.

Lol Ken, I realized that borers make larvae, not caterpillars at 7 in the morning and thought of editing it out but didn't, oops.

FataMorgana, it's terrible, isn't it? I've watched many of the local ash trees succumb and wonder how much time this tree has left. Hubby and I are already discussing a replacement.
