Brown butterfly make distant voyages successful light congeners

Darker monarch butterfly wings means that they are better equipped to fly long distances than their lighter cousins, found the American experts, the results of which were published in the journal PLoS One.

North American monarch butterfly (Danaus plexippus) is among the insects that migrate over long distances. In summer, these butterflies and their larvae prefer to live in the temperate and subtropical regions of the U.S., and in autumn and winter, they migrate to the southern borders of Mexico and other Central American countries. There are cases when the monarchs migrate to other continents, overcoming a few thousand miles and not getting lost when traveling.

Previously it was thought that the bright colors need a monarchy to a "warning" of predators on their toxicity.

Biologists from the University of Georgia (USA) found that the colors of monarchs is directly linked to their ability to make long journeys. Scientists using special installation studied 121 butterfly flying ability and found that dark orange insects overcome distances successful individuals with light wings.

It is unclear exactly how the associated endurance butterflies and the color of their wings. However, the authors believe that their results will be useful in future studies colors of butterfly wings of different species.
