Monarch Butterfly Life Cycle: Egg to Adult (Danaus plexippus) with Photos

From milkweed egg to striped caterpillar, jade chrysalis, and fluttering monarch, witness metamorphosis, migration, and our role in protecting Danaus plexippus across North America today.

On the underside of a milkweed leaf, the world begins small enough to miss unless you kneel and look closely. In this first photograph the newborn is still a whisper of life, a pale pinhead egg collapsed into a glistening scrap, the tiny caterpillar beside it like a gray comma punctuating the green. It has just eaten the soft shell that cradled it—its first meal, its first thrift. The leaf’s pale roads of veins radiate around the hatchling; within that simple map lies all the geography it needs.

By the second photograph appetite has taken its proper throne. These pilgrims wear a uniform of warning: bands of yellow, black, and white—stripes as bright as hazard tape, a heraldic banner advertising the bitterness borrowed from milkweed. Each bite draws down defensive latex; yet the caterpillars feed undeterred, pausing to snip the leaf’s veins to quiet the flow. Their black, threadlike “tentacles” nod as they travel, and their peppery pellets—frass—collect like midnight hail. Five times they will outgrow themselves, shrugging off skins to reveal wider, hungrier versions within. The room is strewn with green rib and ragged edges; the air has the gentle smell of cut stems. All the while, milkweed’s poisons, the cardenolides, pass into growing bodies and become their bodyguard.

At last a hush. A final meal, a purposeful wander. The caterpillar chooses a high eave of the world—a stem, a stick, the corner of your rearing tent—and hooks itself into a downward J. Within hours the skin splits like a soft zipper; the striped creature pours itself out of itself and seals into a smooth chrysalis.

Here, the caterpillar has attached itself to a silk pad from which it hangs. Underneath the skin, the caterpillar is transforming to the chrysalis. In these photographs the silk pad and chrysalis attachment from a previous transformation are in the foreground.

The following photograph and video catch the moments into becoming: the jade lantern has become transparent, darkening, its gold studs glinting like constellation points, and through the thinning walls the folded wings show, orange smoldering under smoke. Inside, old tissues have dissolved into a living broth; imaginal discs—tiny blueprints carried since the egg—have flowered into legs, eyes, and flight. To call it “metamorphosis” is correct; to call it mystery is truer.

When the case opens the butterfly backs into the bright. It clings while the crumpled wings fill and flatten, hemolymph pumping life into every cell. In the next image the adult drinks from a petunia trumpet, a jeweled ember with white-spotted hems. The monarch—Danaus plexippus—tests the wind with new, purposeful wings. Its scientific name nods to ancient stories: Danaus after the Greek mythic king of Argos, a father who fled with his fifty daughters across the sea; plexippus for Plexippus, a figure of the same old tales—his name carried forward into this wanderer of the sky. The English name “monarch” is said to honor both its regal size and domain, and, some say, the orange-and-black of William of Orange. Kings and myths gathered like cloak and scepter around a creature that weighs less than a paperclip.

No butterfly has entered human life more completely. Schoolchildren cradle jars of milkweed sprigs and tape handwritten labels to chrysalides lined like seed pearls along a classroom window. Taggers kneel in September light, add a tiny disc to a wing, and write down time and place so the journey south can be traced. In the mountains of Mexico, where oyamel firs hold winter like a secret, people fold the monarch’s return into the Days of the Dead, believing that souls ride home on those wafers of flame. Gardeners tuck swamp milkweed into narrow beds and call their yards “waystations.” Photographers, such as myself, record the stories that happen leaf by leaf.

In early July a Monarch caterpillar revels in milkweed flowers.

Yet our touch is not simple. Fields simplified by herbicides have shaved milkweed from fencerows; tidy mowing removes nectar from roadsides in the tender weeks of migration; captive rearing in vast numbers, though done with reverence, may carry unintended risks of disease and weakened orientation. The monarch asks us to enlarge our sense of home beyond the fence: to let patches of milkweed lift their pale crowns in rough corners; to choose late-blooming asters and goldenrod; to keep a few ditches shaggy until the travelers pass. Conservation, like metamorphosis, is work that happens inside ordinary days.

Watch the cycle again in my images—egg to appetite, appetite to stillness, stillness to wing—and hear what it whispers in the steady voice of milkweed leaves and soft fall air. Rachel Carson wrote that “those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts.” Here beauty wears stripes and beads of gold, sips from garden petals, and threads a continent with its frail insistence. The monarch’s life is a ribbon we can follow with our eyes and, if we are willing, with our hands—gentle hands that leave room for milkweed to rise, for caterpillars to feed, for a chrysalis to darken and a window to fill, one bright morning, with wings.

On a personal note, this season was a success. Monarchs visited our milkweed patch several times allowing me to save/harvest nineteen eggs/caterpillars and raise them until release.

Explore Louisa Duemling Meadows: Nature and Conservation

The Louisa Duemling Meadows celebrate conservation and biodiversity, showcasing vibrant flora and honoring Louisa Duemling’s legacy as a steward of nature.

The Louisa Duemling Meadows, nestled within the expansive embrace of Sapsucker Woods, offers a vibrant tableau of life, brimming with opportunities for exploration and a sense of wonder. This new trail, winding through golden fields and punctuated by bursts of wildflowers, whispers tales of the land’s natural and cultural heritage.

Louisa Duemling: A Steward of Nature
Louisa Duemling, the meadows’ namesake, was a dedicated conservationist and philanthropist who supported the Cornell Lab of Ornithology’s mission to protect birds and their habitats. Her legacy lives on in these serene fields, where her commitment to preserving the environment is reflected in every thriving plant and songbird.

Black-eyed Susans: The Meadow’s Golden Treasure
Dominating this summertime landscape with their radiant yellow petals and dark central disks, Black-eyed Susans (Rudbeckia hirta) are a hallmark of the meadows. These cheerful blooms are a delight to the eye, a cornerstone of meadow ecosystems. As members of the Asteraceae family, their composite flowers serve as a rich nectar source for pollinators like bees and butterflies, ensuring the vibrancy of these fields.

Historically, Black-eyed Susans have been used in traditional medicine by Native American tribes for their putative anti-inflammatory properties. Their ability to thrive in diverse conditions also makes them a symbol of resilience and adaptability.

A Symphony of Green and Gold
Walking through the trail, one is greeted by the harmonious interplay of goldenrods (Solidago spp.), milkweeds (Asclepias spp.), and asters (Symphyotrichum spp.). Goldenrods, with their feathery clusters of yellow blooms, are often mistaken as allergenic culprits, though it is the inconspicuous ragweed (Ambrosia artemisiifolia) that deserves this reputation. Milkweeds, with their milky sap and delicate pink or white flowers, are vital to monarch butterflies (Danaus plexippus), serving as the sole food source for their larvae.

Among these botanical wonders, the birdhouse stands as a sentinel, a reminder of the intricate relationship between flora and fauna. These wooden structures provide safe havens for cavity-nesting birds like Eastern Bluebirds (Sialia sialis) and Tree Swallows (Tachycineta bicolor), fostering biodiversity within the meadow.

A Horizon Framed by Pines and Clouds
The open meadow trails, flanked by clusters of Eastern White Pines (Pinus strobus) and punctuated by the azure sky, invite reflection and renewal. This is a place where the human spirit can align with the rhythms of nature, where each step reveals new layers of beauty and discovery.

Embracing the Spirit of Discovery
To wander the Louisa Duemling Meadows is to immerse oneself in the timeless dance of life. The trail, carefully marked yet wild in essence, invites visitors to lose themselves in its beauty while finding solace in its quietude. This is not just a path through nature—it is a journey into the heart of conservation and a celebration of the life that thrives under Louisa Duemling’s enduring legacy.

As you leave the meadow, carry with you not just the memory of golden flowers and vibrant skies but the inspiration to cherish and protect the natural world. The Louisa Duemling Meadows are not only a gift to those who walk its trails but a reminder of the profound impact one can have in preserving our planet’s fragile beauty.

The Last Bloom and the Bee’s Blessing

In the final bloom of the season, a honeybee’s delicate dance with the Queen of the Night captures the fleeting beauty of nature’s cycles. Discover the profound connection between flower, bee, and life’s rhythms.

The Epiphyllum oxypetalum, commonly known as the Queen of the Night, is a remarkable plant. Native to Central America, this epiphyte is known for its large, fragrant flowers that bloom only once a year and last just for a single night. The fleeting nature of its bloom makes it a symbol of transience and beauty in many cultures. For me, this flower is a quiet, intimate connection to the rhythms of nature that play out around our home in Ithaca, New York.

The images you see include the last flower of the season, a white starburst of delicate petals encasing a universe of intricate details. As the day progresses, the flower remains open, revealing the next chapter in its life cycle—the possibility of forming fruit. This potential is entirely dependent on pollination, a process that is both beautifully simple and astonishingly complex.

A honeybee, a tiny yet essential participant in the grand scheme of things, hovers and lands delicately on the flower. In the first image, the bee appears tentative, exploring the outer fringes of the flower’s central structures. Its wings are still, as if it has just touched down after a careful, deliberate approach. The stamens, like a thousand arms extended in welcome, offer their pollen. Each grain of pollen is a promise, a potential seed, carried with the hope of propagation. The bee is the flower’s messenger, moving from one bloom to another, ensuring the continuity of life.

As I observe the bee’s actions through these photographs, I can’t help but reflect on the importance of these small creatures. Their work often goes unnoticed, yet without them, our ecosystems would collapse. The honeybee, in particular, has been a focus of concern in recent years due to declining populations, largely attributed to human activities. But here, in my garden, this bee is simply going about its day, unaware of the broader implications of its existence. It is focused on the task at hand, a model of mindfulness in action.

In the second and third images, the bee has moved deeper into the flower, its body now dusted with pollen. It is fully engaged in its work, undeterred by the enormity of its task. The pink style of the flower contrasts sharply with the white petals and the yellow stamens, creating a vibrant tableau of life. The bee’s body is now part of this scene, its presence both functional and aesthetic. It is not just a visitor; it is an integral part of the flower’s story.

The fourth and fifth images capture the culmination of the bee’s efforts. Having gathered what it came for, the bee is ready to move on, its job done here. The flower, too, has fulfilled its role for the season. The energy it expended to produce this magnificent bloom will now be directed towards forming fruit, provided that the pollination process is successful. If it is, this single flower will give rise to a new generation of plants, continuing the cycle of life.

But there is another, more personal layer to this story. This is the last flower of the season. It carries with it the weight of finality, the knowledge that soon the plant will rest, conserving its energy for the next year’s bloom. As I contemplate this, I am reminded of the cycles that govern not just plant life, but all life. There is a time for blooming, a time for fruiting, and a time for rest. Each phase is essential, each one a preparation for the next.

A bonus view of the honeybee in action

In allowing this flower to form fruit, I am participating, in a small way, in this cycle. We are stewards of the natural world, responsible for nurturing and preserving the life forms that share our planet. The honeybee, the flower, and I are all connected in this intricate web of life, each playing our part in the unfolding drama of existence.

These photographs are a meditation on life, a reminder of the beauty and fragility of the world around us. They capture a moment in time, brief encounters between a flower and a bee, but they also speak to something larger, something timeless. The Epiphyllum oxypetalum may bloom for just one night, but its impact, like that of the honeybee, reverberates far beyond that brief window. And in that, there is a profound lesson for all of us.
