The monarch butterfly can be found in open fields and meadows with milkweed.
Adult monarchs feed on nectar from flowers, including milkweed. The larvae eat only milkweed leaves.
Eating milkweed causes the monarch to store alkaloid, which makes them unappetizing and toxic to predators. The viceroy butterfly has evolved to look like the monarch, tricking predators into believing it too is toxic.
