Watchable Wildlife: Monarch Butterfly

Did You Know?

  • Monarchs, like all other butterflies and moths, go through egg, larval (caterpillar), chrysalis (pupa), and adult stages.
  • Monarch caterpillars ingest milkweed that contains a toxic compound. The presence of this toxin is used by the monarch butterfly as a defense against predators.
  • Other butterflies, such as the Viceroy, mimic the Monarch's colors to pretend that they are also toxic to predators.
  • In late August, masses of monarch butterflies begin an epic migration stretching thousands of miles from areas across the United States and as far north as Canada (east of the Rocky Mountains) to overwinter in mountaintops of Central Mexico.
