We received a question from a reader a while ago about a small black and white worm he found in a carton. Actually, he didn’t ask a question so much as write us a statement, which went as follows: “worm found in sealed carton the color was black and white and about a half inch long.” (That’s the entire email.) We presume the reader found the worm in some sort of food carton because we don’t know any other carton one would likely find a worm in. (A milk carton? A cigarette carton? These seem like less inviting places for a worm.) As you can see, the reader didn’t directly ask any question, but we’re assuming he’s curious what he found. So, what is the black and white worm that our reader found in a (food) carton?
