Mimicry is the ability to appear to be or to imitate something other than what you really are. The use of mimicry is prevalent throughout nature and is a prime example of evolution by natural selection. Butterflies use it as a protection mechanism in their larva stage and in the final adult stage. Either to trick predators into thinking they are an inedible species or perhaps an entirely different organism all together. Foremost, the intention of mimicry is to draw attention to yourself. This is usually achieved, but not always, by advertising your presence with bright colours and is known as "aposematism". These bright colours are probably easier for predators to learn and therefore likely reduces the number of casualties necessary before the predator learns the pattern to avoid and providing the mimic with protection.
