What time of the year do caterpillars turn into butterflies?

It’s dependent on the kind of butterfly, I’m afraid.  If you’d like a general answer, it’s a result of changes in temperature and availability of food.  A caterpillar usually munches on leaves, so when the leaves stop being available, they change to another type of food, like tree sap.  Then it stops munching for a while and hangs out in its pupa, or chrysalis.  And then when the weather gets warm, the caterpillar becomes a butterfly, and flies around looking for food, or a mate, or to lay its eggs.
