How is the button formed by the caterpillar just before it becomes a chrysalis? (just before it hangs down like a "j")Is it from a mouth part or an anal part?
Question Date: 2002-05-09
Answer 1:

I can't help you with the "button" part, but it is the mouth (anterior)end that is attached to the branch, and the posterior end that hangs down. Here's an interesting site that shows a butterfly life cycle.
