Remember this guy? He was just about full-grown when I checked the other day. Still living the good life on what has turned out to be the only milkweed plant that didn't get freezer burnt in our cold spell the other week. Still behind bars, too. There's plenty of room for him to get out while he's still a caterpillar, but I bet he'll end up doing his thing from the inside of the wires.
I'll be back to check on him tomorrow.
