Why do butterflies have different colors and patterns on their different wing surfaces?
Speaker: Professor Antonia Monteiro
Synopsis: Both the urge to be bright and beautiful to find a mate that will accept you, and the urge to escape predators, have been shaping the colors and patterns on the wings of butterflies for millions of years. The result of these, often antagonistic, selection pressures has been the evolution of distinct patterns on dorsal and ventral surfaces, on fore and hindwings, and in males and females. This optimization is thought to offer maximum protection from predators while still attracting the opposite sex. I will explain some of the genetic and developmental wizardry that butterflies use to achieve this result.
