Awesome Husband called me to the front porch, where an unknown caterpillar was crawling around on a blanket the dog had been relaxing on out near the woods.
"Oh dear, the poor thing!" I thought. "It will starve if I just leave it there. I'll photograph it and then put it on a tree in the backyard." So, photographed and relocated. Then it just needed to be identified.
Using the excellent site Discover Life , I quickly found the mystery critter.
Hm... "forest tent caterpillar Malacosoma disstria " Uh-oh. "...often defoliates large areas..." Oh dear.
