Butterflies, unlike several other creatures, cannot sting or bite to fight back predatory attack. Therefore, to escape from predators, butterflies have evolved various protective adaptations, right from the egg to the adult stage.

A lower temperature slows down their physiological process. Butterflies need to regulate their temperature and therefore they may bask in the sunlight to increase their temperatureto withdraw underneath a leaf to lower their temperature.
