Caterpillars are on the move. We get a bunch of Painted Lady butterflies (Vanessa cardui) showing up every year, so that’s my first guess as to what these are. There is one photo on the internet that kind of matches… Teach your kids to use a camera well.
@cliffordbeshers Some sort of tent caterpillars I think. The article says that all of them are moths as adults. Eastern Tent Caterpillars are a serious pest here in the eastern US.
@JMaxB Ah, that looks much better, thank you. We have moths that look just like this. en.wikipedia.org/wiki/Mala...
