Who it is

• Scientific name: Danaus plexippus
• Family & relatives: An insect in the order Lepidoptera, related to all other butterflies and moths.
• How to spot it: A large orange butterfly with bold black veins, black wing edges, and rows of little white spots.

Its body & abilities

• Size: Its wingspan is about 9 to 10 cm from wingtip to wingtip.
• Weight: Extremely light, only about half a gram.
• Body & adaptations: It has four scaly wings, six legs, two feelers called antennae, and a coiled straw-like tongue for sipping nectar.
• Top speed: A gentle flier that flaps along at about 8 to 12 km/h, riding the wind to travel far.
• Strength: Amazingly, this tiny insect can fly thousands of kilometers on one of the longest journeys of any butterfly.
• Senses: It sees colors and ultraviolet light, tastes with its feet, and smells flowers with its antennae.
• Growing up: It changes completely: an egg hatches into a caterpillar, which forms a green chrysalis and comes out as a butterfly.

Where it lives

• Habitat: Meadows, gardens, fields, and roadsides where milkweed and flowers grow.
• Where in the world: Across North America, migrating between Canada, the United States, and central Mexico.
• Territory: Not territorial; monarchs wander widely and gather by the thousands at winter resting spots.

What it eats

• Diet: The adult drinks flower nectar, while the caterpillar munches only milkweed leaves.
• Favorite foods: Nectar from many flowers for the adult; green milkweed leaves for the growing caterpillar.
• How it hunts: It does not hunt; it gently visits flower after flower, sipping nectar and carrying pollen as it goes.

How it behaves

• How it moves: Flutters and glides through the air and rests by clinging to leaves and stems with its six legs.
• When it is active: Active by day in the sunshine, and rests with wings closed at night and in cool weather.
• Family life: Mostly travels alone but clusters together in huge groups on trees during winter.
• How it talks: Uses bright colors and scent signals rather than sound to find mates and warn that it tastes bad.
• Babies: The female lays tiny eggs one at a time on milkweed leaves, and each hatches into a hungry caterpillar.

Its place in nature

• Role in nature: A helpful pollinator that carries pollen between flowers; birds and insects eat monarchs despite their bad taste.
• Conservation: The migratory monarch is considered at risk, hurt by the loss of milkweed and changing weather.
• Dangers: Many are eaten by predators or lost to bad weather and habitat loss along their long journey.

Life & legacy

• How long it lives: Summer adults live just a few weeks, but the special migrating generation can live up to eight months.
• In our culture: A beloved symbol of nature and migration, celebrated in Mexico around the Day of the Dead when the monarchs arrive.
• Where to see it: Summer gardens and meadows across North America, and the famous winter monarch forests of central Mexico.
• Fun fact: Some monarchs fly over 4,000 kilometers to reach Mexico, guided by the sun and an inner sense of direction.
