Western monarchs, who migrate to California or Mexico, are the sprinter siblings in the monarch family -- flying fast, for short distances. Eastern monarchs are the marathoners -- flying more slowly, but migrating from Maine all the way to Mexico.
Despite their differences, they have a lot in common: They both rely on milkweed as caterpillars. They both have incredible natural defense mechanisms against predators. And they're both fluttering toward extinction. Thankfully, they have another best defense mechanism: you. Fuel our campaign to save monarchs with a donation today.
