The monarch butterfly is one of the most recognizable and well studied butterflies on the planet. Its orange wings are laced with black lines and bordered with white dots. Famous for their seasonal migration, millions of monarchs migrate from the United States and Canada south to California and Mexico for the winter.
Monarch butterflies are native to North and South America, but they’ve spreadto other warm places where milkweed grows. No longer found in South America, monarchs in North America are divided into two main groups: The western monarchs, which breed west of the Rocky Mountains and overwinter in southern California; and the eastern monarchs, which bre...
The female monarch butterfly lays each of her eggsindividually on the leaf of a milkweed plant, attaching it with a bit of glue she secretes. A female usually lays between 300 and 500 eggs over a two- to five-week period. After a few days, the eggs hatch into larvae, otherwise known as caterpillars in the moth and butterfly world. The caterpillars’...
Monarchs’ colorful pattern makes them easy to identify—and that's the idea. The distinctive colors warn predators that they’re foul-tasting and poisonous. The poison comes from their diet. Milkweed itself is toxic, but monarchs have evolved not only to tolerate it, but to use it to their advantage by storing the toxins in their bodies and making th...
In the east, only monarchs that emerge in late summer or early fall make the annual migration south for the winter. As the days get shorter and the weather cooler, they know it’s time to abandon their breeding groundsin the northern U.S. and Canada and head south to the mountains of central Mexico, where it’s warmer. Some migrate up to 3,000 miles....
Conservation groups have petitioned the U.S. government to add the monarch butterfly to the Endangered Species Act list. While a decision has not yet been made, it’s clear the species is in decline, facing a number of threats. Western monarchs have declined by more than 99 percent since the 1980s. Eastern monarchs have declined by an estimated 80 p...
As an iconic and loved species, monarchs have received a lot of attention from conservationists. Projects exist across North America. Public awareness campaigns encourage people to plant milkweed in their yards and cities—just look up the type that’s right for your region. There are also a number of citizen scientist opportunities, where regular pe...

Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects that includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, making it the second largest insect order (behind Coleoptera) with 126 families and 46 superfamilies.
What do Butterflies see? Butterfly eyes contain thousands of tiny lenses and special photoreceptors for ultraviolet light that scientists believe help them navigate during long migrations. Many flowers use UV markings invisible to human eyes to attract butterflies, which are crucial pollinators.
