The flashy colors of some butterflies could exhibit their speed and activeness, much like a cover of sharp yellow color on a sports car. Recent research indicates birds can learn to understand these visible signs, avoiding not just butterflies they have failed to catch in the past but as well as lookalikes species.
The study offers so much vital proof to date for the notion of elusive mimicry, a method in which animals defend themselves against predators by matching to the colors or structures of agile relatives. Initially suggested over 60 years ago, the theory has been a challenge to experiment with.
