The monarch butterfly Endangered - exhibits the most highly evolved migration pattern of any known species of butterfly or moth and perhaps any known insect. Climate change threatens to disrupt the monarch butterfly’s annual migration pattern by affecting weather conditions in both wintering grounds and summer breeding grounds. Colder, wetter winters could be lethal to these creatures and hotter, drier summers could shift suitable habitats north. WWF’s 2013 report from Mexico showed that the number of monarch butterflies wintering there was at its lowest in 20 years.
