monarch butterfly

Monarch butterflies with more white spots on their mostly orange-and-black wings are more successful at long-distance migration. Some scientists think the spots may affect airflow around their wings.

Michigan State University researchers have developed a forecast model of changing climates to predict which counties in the midwestern U.S. and Ontario are most likely to offer the most hospitable breeding grounds for monarch butterflies.

The International Union for Conservation of Nature (IUCN) has listed the migratory monarch butterfly as endangered. University of Michigan ecology professor Mark Hunter, who studies monarch populations, said this addition to the list is crucial for change.
