Hey!
I was looking for this answer myself. I don't know if these are caterpillars on your tomato plants (that is what I am experiencing), but according to the site referenced below, these white sacks are the pupae of the Braconid Wasp. The Braconid Wasp is a natural predator of hornworms (my type of caterpillar). Apparently, the wasp lays its eggs in the prey, and when the eggs hatch into larvae, they begin eating the hornworm's organs. The white sacks are actually the cocoons from which the wasps will emerge.
Even though the caterpillar was eating my tomato plants, I feel really bad for it. I might put it out of its misery. I can't imagine something eating my insides when I'm alive!

it keeps the claw from getting caught on things.
Wooly bear caterpillars have orange fuzz and a black body. The orange fuzz on a wooly bear caterpillar actually keeps the caterpillar warm in colder climates.
It is the nature of the universe; the universe keeps getting older and so does everyone and everything in it. It's the nature of things.

Well, not everything, but most things like: Bugs, birds and other animals. And it keeps you from getting wet when I rains and...getting a sunburn. Dunno what else to list...
