I love it when nature takes care of a problem. This is a tomato hornworm caterpillar that has been parasitized by a braconid wasp. I had been looking for the blasted thing, as I'd noticed the hornworm damage on my plants, but couldn't find it. Fortunately, the wasp had no such difficulty. This dude is going to be left alone until all the new wasps emerge, and then I'll probably plop it into a bottle of alcohol to preserve it, because I'm weird like that.
