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.

Exploring Ancient Wisdom in Today’s Healing Practices

As I waited during my wife’s physical therapy session, the connection between ancient healing traditions and modern medicine revealed a journey of resilience and hope.

Standing in the cool autumn sunlight, I find myself pacing beneath the sturdy Doric columns of this medical campus in Northeast Ithaca, waiting as Pam undergoes another session of physical therapy. The simplicity of the columns strikes me—clean, white, and unadorned. They hold up the building with a kind of timeless grace, a quiet reflection of ancient design.

The architecture of the Medical Office Campus of northeast Ithaca is graced by doric columns arrayed in a row forming a portico colonnade. The original Greek Doric columns were fluted, and had no base, dropping straight into the platform on which the temple or other building stood. The capital was a simple circular form, with some mouldings, under a square cushion that is very wide in early versions, but later more restrained. Here the form of the capital is mirrored in the base. 20 Arrowwood Drive, Ithaca, Tompkins County, New York State

Doric columns are symbols of strength and stability. In this moment, they remind me of the quiet resilience I’ve seen in Pam throughout her recovery. Each column, solid and unwavering, reflects the foundational principles that underpin both architecture and the healing arts. Just as these columns have withstood the passage of centuries, modern medicine, too, stands tall on the legacy of ancient knowledge.

As I lean against one of these pillars, I think about the deep connections between ancient civilizations and the medicine we practice today. The origins of healing reach back to the Egyptians, who understood anatomy with remarkable precision. They would have been familiar with the use of medicinal plants. It’s remarkable to think that the surgeries performed back then, basic as they were, have evolved into the complex procedures of modern times, procedures like the one that replaced Pam’s hip with the efficiency of a machine through the care of skilled hands.

I look up at the sky, tracing the outline of the roof these columns support. The Greeks, with their reverence for observation, would have appreciated the rational design of this building. Hippocrates, the father of medicine, laid the groundwork for clinical observation, a method still used by the doctors caring for Pam. They probe, ask questions, and observe her movements, trying to decipher the hidden ailments within her body, much as the ancient physicians did centuries ago. It’s in this continuity that I find comfort—knowing that the doctors and physical therapists here are part of a long tradition, stretching back to Galen, who wrote about anatomy and physiology in ways that informed medical students for generations.

Modern medicine, like these columns, is a blend of the old and the new. Acupuncture, an ancient Chinese practice, is now commonly recommended for pain relief, a reminder that even today we rely on wisdom passed down through millennia. Pam’s therapists blend tradition with cutting-edge technology, using machines that track her progress and exercises that help her regain strength. Yet, at the heart of it, the human body heals the way it always has—with time, patience, and care.

As I walk the perimeter of the building, past patches of sunlight falling on the sidewalk, I’m struck by the parallels between the construction of this space and the body’s own repair. Both depend on a solid foundation. Roman innovations in public health, sanitation, and the idea of hospitals have shaped the spaces where we now seek healing. And here, in this modern medical facility, the connection to those roots feels tangible, much like the stones beneath my feet.

The name Aster comes from the Ancient Greek meaning “star”, referring to the shape of the flower head. ‘Aster’ species are used as food plants by the larvae of a number of Lepidoptera species. These asters grew wild on an otherwise landscaped medical campus. Found on an eaqrly autumn morning near 10 Brentwood Drive, Ithaca, Tompkins County, New York State

Asters, blooming nearby, sway gently in the breeze. They too are resilient, much like Pam. Their purple blossoms remind me of the hope that pervades our journey. The columns stand as sentinels of a kind of knowledge that is both ancient and ever-evolving—a blend of science, history, and faith in the power of the human spirit to endure.
