Unlike many insects, butterflies do not experience a nymph period, but instead go through four stages: Egg, Larva, Pupa and Imago. The adult butterflies have four wings, but unlike moths, the fore and hindwings are not hooked together, permitting a more graceful flight. Some butterflies have evolved 'eye' like markings on their wings, scaring off some birds, or allowing the butterfly a chance of escaping in the confusion when the bird simply pokes a hole in one of the wings.
