Name That Caterpillar

I did some research on the caterpillar I posted about a couple of days ago. It's the Easterntent caterpillar. When mature it is a moth not a butterfly.....I hate to say it but it sort of ruins it for me...It's not very pretty...and they always manage to fly into the house at night and the cats go crazy chasing them. Another annoying thing is the "tents" they build in our trees. We try to break them up before they get too big, they look like they contain thousands of the little buggers when they get large. It's kinda creepy to look into them and see all the little guys squirming around...
