In the animal kingdom, colors are usually used for camouflage, but are also used as warning signs to other animals to stay away. In butterflys, colors are a beautiful sight, but they're mostly used for camouflage and as a tactical tool, not necessarily to warn animals to stay away, but rather, some butterflys have patterns on their wings that resemble eyes, eyes that tell predators "I can see you!" For these reasons, the diversity created by different colors of butterfly wings can help preserve the lives of butterflys well adapted to the environment, whether it's patterns on their wings, or camouflage, the population will grow.
