High food stress may impact wing size and coloration -- both indicators of migratory success -- in monarch butterflies monarch butterflies migrate long distances according to the seasons every year. They are sometimes confused with the viceroy butterfly because of the similar size, color and wings pattern however, an extra black stripe across the monarch butterfly wings separates it from the viceroy butterfly. In monarch butterflies, differences in wing morphology between migratory and resident populations suggest that migratory populations have undergone selection for larger (as measured by length and area) and more elongated (as measured by roundness and aspect ratio) forewings.
