Below is the article summary. For the full article, see monarch butterfly.

monarch butterfly, Species (Danaus plexippus, family Danaidae) of milkweed butterfly, occurring worldwide but mainly in the Americas. It is the only lepidopteran species to make a true migration (a two-way flight by the same individual). In North America, thousands of monarchs gather in autumn, migrate southward, sometimes more than 1,800 mi (2,900 km), and return north in spring. The distinctive coloration of the adult’s wings (reddish brown, with black veins, a black border, and two rows of spots) warns predators of its bad taste. Several other species derive protection by mimicking its coloration.
