Butterflies WWF Wall Calendar: Butterflies are arguably the most dazzling creatures on earth. That humble larva should undergo metamorphosis into such an exquisite flyer is still one of the most fascinating phenomena in the animal world. Its beauty is fleeting, however, as the butterfly's lifetime is brief. The up-close images in this colorful calendar capture butterflies basking in the sun, avoiding predators, gathering nectar, and perching for potential mates. In the U.S. and Canada, World Wildlife Fund (WWF) receives 50 cents for each 2013 WWF calendar purchased, with a guaranteed contribution of $50,000. EAN: 9781620210987
