““pupa stage is a short "rest stop" before it becomes an adult. Pupas don't eat, they just rest. Maybe they're saving up energy to fly. The complete change from larva to adult happens while it is a pupa. When a butterfly caterpillar sheds its last skin, its inner skin hardens into a chrysalis. A moth caterpillar doesn't make a chrysalis. It makes a cocoon. First, it hooks a silk strand to the top of twig. Next, it fastens that same thread to the bottom of the twig. Then it hangs head-down and spins threads across for the rest of the cocoon. Find a chrysalis or cocoon and watch the new butterfly or moth emerge! What It Looks Like””
