Butterflies are a kind of insect that changes completely as it goes through its life. A butterfly starts as an egg, which hatches into a caterpillar. Caterpillars spend all of their time eating leaves from their favourite plants. When they are old enough, caterpillars spin a cocoon and while they are asleep inside it, they change into a butterfly. Butterflies eat nectar from flowers, and live for a much, much shorter time than caterpillars.
