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.

Discover the Bold Jumping Spider: Nature’s Agile Hunter

Small in size but vast in charisma, the Bold Jumping Spider hunts with precision, agility, and a gaze that almost seems to return your own.


There, pressed into the grain of the boardwalk like a dark fleck of forest lint, the Bold Jumping Spider (Phidippus audax) waits—motionless, yet alert. To the untrained eye, it may seem insignificant, even nondescript. But a closer look reveals a creature of fine design and surprising charisma: a compact body cloaked in velvety black, adorned with pale markings like runes, and forward-facing eyes that gleam with eerie intelligence.

Unlike the orb weavers and net-spinners of spider lore, Phidippus audax does not rely on traps. It is a hunter in the truest sense—an animal that lives by leaping toward its future. With eight powerful legs and a muscular abdomen, it can launch itself many times its own body length, arcing through the air toward an unsuspecting moth or beetle. Yet it does not leap blindly. It trails a single silken thread behind it—a safety line, a commitment to survival. It is an act of courage tethered to caution.

Most remarkable are its eyes. A quartet of simple lateral eyes scan for motion, but the two large, front-facing principal eyes are something more—a rarity among arthropods. They grant it acute vision, with the ability to detect detail, movement, and even depth. When it turns its gaze toward you, you feel seen—not just registered, but regarded.

These spiders are active thinkers, decision-makers. They test their environment with movements that can almost be described as exploratory. They do not walk so much as prowl, stepping into shadow and light with an awareness that seems out of scale for their size.

And though they are often met with fear or disdain, Phidippus audax poses no threat to humans. It asks only for a few square inches of wood or leaf to stake its claim. In return, it offers a glimpse into a different kind of grace—an agile, silk-spinning daredevil, leaping with acute precision.

To observe one is to witness the meeting of design and instinct, form and function, in perfect miniature. In the vast, humming network of woodland life, the Bold Jumping Spider may be a small player, but it performs its role with flair. If the trees are the spires of the forest cathedral, and the ferns its leafy congregation, then Phidippus audax is a kind of sacred rogue—silent, swift, and utterly unconcerned by our towering presence.

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.

The Hidden Songster of Ithaca: My Afternoon with a Gray Catbird

Amidst spruce needles, a Gray Catbird’s mew captivated me; a hidden minstrel whose dulcet mimicry and secretive charm turned my backyard in Ithaca into an amphitheater of nature’s most intricate symphonies.

In my backyard, amidst the spruce trees that seem to touch the sky, I had a unique encounter with a little gray bird known as the Dumetella carolinensis, or more commonly, the Gray Catbird. I learned that “Dumetella” comes from the Latin word for “thorny thicket”, hinting at its penchant for skulking in dense underbrush, often hidden from sight. Its species name, “carolinensis”, pays homage to the Carolinas, though this bird has certainly made a comfortable home here too.

This particular visitor had a call reminiscent of a cat’s mew, a curious sound that first drew my attention. As I peeked through the window, I noticed it wasn’t just imitating felines; it was a veritable mimic, echoing the songs of other birds, even copying the croaks of tree frogs, and sometimes the mechanical noises of our own making. Its syrinx, a true marvel of nature, allows it to produce two sounds simultaneously – an impressive feat for such a small creature.

Unlike the showy northern mockingbird or the brown thrasher, which repeat their musical phrases several times, this Gray Catbird preferred to sing each of its phrases just once. Its song was a bit raspier, less melodic but still captivating in its own right.

It’s interesting that the Gray Catbird often chooses to remain hidden when it sings, favoring the inner sanctuary of bushes or trees like the spruce in my yard, a natural stage set by verdant leaves and branches. And while I watched, it seemed content in its concealment, a master of melody cloaked in foliage.

As I observed it, I recalled reading that the Gray Catbird’s diet is as varied as its repertoire of sounds. Fruits and berries make up about half of its diet. This little bird has quite the palate, enjoying a smorgasbord that includes mealworms, earthworms, beetles, and other insects, not to mention the bounty of summer offerings such as ants, beetles, grasshoppers, caterpillars, moths, and a selection of berries from holly, cherry, elderberry, poison ivy, bay, and blackberries.

I made a mental note of the date, captured in the metadata of the photograph I snapped: 2021, from my home in Ithaca. A simple image, yet it encapsulated a serene moment of connection with a creature so adept at concealment and mimicry, a moment I would treasure. The Gray Catbird, with its unique song and dietary habits, has become a beloved part of my backyard symphony.
