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.

The Autumn Tapestry of Cayuga Lake: A Journey on the Treman Park Lake Loop

Autumn’s Arrival Along Cayuga Lake

In Autumn 2024, the Treman Park Lake Loop of the Cayuga Waterfront Trail in Ithaca, New York, unfurled a vibrant display of seasonal transition. The natural landscape, adorned with fiery hues of reds, oranges, and yellows, reflected in the rippling waters of Cayuga Lake, creating a harmony of color and light. This is a scenic journey through stories of plant and animal life that call this place home—including the majestic Osprey (Pandion haliaetus) that nests along the shore.

The Osprey’s Watchtower

A sight to greet visitors is the solitary osprey nest perched high on a pole. Used by Osprey families during their breeding season, this nest stands as a testament to their remarkable recovery in the Finger Lakes region. Ospreys, once declining due to pesticide use, have rebounded significantly following conservation efforts.

With a wingspan of up to 6 feet, these raptors are expert fish hunters, often seen diving talons-first into the lake to snatch their prey. During autumn, as their young take flight, the nest remains an empty marker of the summer’s success—a reminder of the cyclical nature of life along the lake.

Did You Know? Ospreys are often referred to as “fish hawks” because fish make up 99% of their diet.

The Meadow and Its Golden Touch: Reedbeds and Goldenrod

Surrounding the osprey pole, expansive meadows of grasses and reeds sway with the breeze. Among these are stands of Common Reed (Phragmites australis), a tall grass with feathery plumes that catch the sunlight. While Phragmites can sometimes be invasive, they provide crucial shelter and food for various species of birds and insects.

Intermixed with the reeds are patches of Goldenrod (Solidago spp.), whose bright yellow flowers are a signature of late summer and autumn in the Northeast. Goldenrods are critical for pollinators, offering nectar to bees, butterflies, and migrating insects like the Monarch butterfly (Danaus plexippus).

Ecological Note: Goldenrods are often mistakenly blamed for allergies; the real culprit is ragweed (Ambrosia artemisiifolia), which blooms at the same time but releases airborne pollen.

A Lake Alive with History and Beauty

The shimmering blue waters of Cayuga Lake form the centerpiece of this trail. The lake, stretching nearly 40 miles, is the longest of the Finger Lakes and steeped in geological and cultural history. Its name is derived from the Cayuga Nation, part of the Haudenosaunee Confederacy, who inhabited the region for centuries.

The striking red lighthouse in the water serves as a vivid counterpoint to the natural surroundings. Built to aid navigation, it now stands as a picturesque focal point for photographers and nature enthusiasts alike.

Cayuga Inlet Light Beacon

In the distance, a sailboat glides across the lake—a serene reminder of the recreational draw that Cayuga Lake holds year-round.

The Forest Fringe: A Kaleidoscope of Color

The forests that fringe the meadow and the lake present an explosion of autumn color. Trees such as Sugar Maple (Acer saccharum), Red Oak (Quercus rubra), and Black Cherry (Prunus serotina) dominate the canopy, their leaves transforming into brilliant oranges, scarlets, and deep burgundies. The Sugar Maple, in particular, is renowned for its vibrant golden-orange foliage, a hallmark of the northeastern fall.

The Ithaca Yacht Club lies south of Maplewood Point

Closer to the ground, the understory hums with the activity of migrating birds and foraging mammals. Squirrels can be seen gathering acorns, preparing for the winter months ahead, while chickadees flit among the branches, calling their cheerful “fee-bee” notes.

Historical Fact: The Finger Lakes were carved out by retreating glaciers over 10,000 years ago, leaving behind these deep, elongated lakes and fertile soil that supports rich biodiversity.

A Path Through Time and Nature

Walking the Treman Park Lake Loop is a sensory journey—the crispness of the autumn air, the rustling of reeds, and the rhythmic lapping of waves against the shore combine to evoke a timeless tranquility.

From the vibrant meadows to the osprey’s lofty perch and the quiet expanse of Cayuga Lake, this section of the Waterfront Trail encapsulates the beauty and diversity of the Finger Lakes ecosystem. Whether for quiet reflection or active exploration, it remains a treasured destination in every season.

Closing Thoughts

As autumn deepens, this landscape prepares for the dormancy of winter. Yet the stories it holds—from the osprey’s nest to the goldenrod’s bloom—remain alive, waiting to be rediscovered with each new season. The Treman Park Lake Loop is not just a trail; it is a canvas of life, change, and history painted by nature’s hand.

Reflection: To walk this trail is to connect with a land shaped by glaciers, nurtured by waters, and home to countless species that continue to thrive amid the ever-turning wheel of the seasons.

Autumn Evening Hike Part 1 of 3

It started with running water…..

Over the weekend the handle of our 60 year old Delta brand kitchen faucet broke off, since we moved here I rebuilt it once and replaced the stainless steel sphere, the central control of the mechanism.  The stem of the sphere must have been faulty because it snapped. Monday, I visited Lowes and the sphere was not in stock.  Just wanting to fix the faucet, I skipped the usual vetting of a new product and grabbed the exact same Delta faucet which was, just like the sphere that broke, made in China.  The next step up in (questionable) quality was three times the price.

Running Water

Yesterday I installed a new faucet in the kitchen sink, a straightforward and unpleasant task that took most of the day.  Late afternoon, while resting up, I brought up the idea of a hike and Pam reminded me we had another clear September day.  Last week, I headed out to capture the Mill Creek waterfall of upper Treman Park at the perfect time of day.  It was a day such as this, warm, a cloudless sky, minimal breeze.

Mill Falls
Pam reminded me this evening I was trying to capture the Mill Waterfall of Upper Treman Park at the perfect moment when the sunlight glazes the pools.

I need to get in place a bit earlier.  Previously, I used a 24 mm wide angle lens and, today, mounted the EF 70-300mm f/4 – 5.6L USM lens on the Canon EOS 1DS MarkIII.  Did not have time to sort through the ND filters, so left the UV on.  The waterfall is in a glen, shaded from direct light at this time of day, sun low in the west.  Given the low light, to save time, I decided to set ISO to a low value (125), set lens to the widest angle (70 mm), and frame the shot using the heavy Manfrotto tripod with ball head.

Needed to crop the image for the above result, still not perfect.  I am seeking to full the entire pool in that glow.

Mo's Bench
Towards the end of her life, my Mom waited for us on this bench while we walked. She enjoyed the sound of the creek, watching and chatting with passerbys. There some out of focus goldenrod right foreground. I frames the shot to catch the flowers and crop out a tree trunk.

Hiking the Gorge Trail

Instead of putting the gear away, I carried that heavy setup on the hike.  The strap around the neck is a lot of stress if it hangs.  With the gear cradled in the crook of my arm it is bearable.

Foot Bridge
The creek is spanned at several points by these stone footbridges, the work of the Civilian Conservation Corps, as are all the gorge trails. This bridge was restored last year. It leads to a marvelous grove of Sycamores.

Needless to say, the pace was sedate.  Pam spent most of the time walking ahead and refusing to be in any shots.  These past weeks, rainfall was light, so the creek is low.  This low flow is a necessary element to a perfect waterfall image.

Golden Rod

I get some great macro shots with that lens.  With just the UV filter, it is quite fast.

Ferns, Lichen, Gorge Wall
The gorge wall rises to the right of the path.
Foot of the Gorge Wall
Very little of the gorge walls do not support thick growth of mosses, lichen, ferns, flowering plants of all kinds. I don’t know offhand the name of the cnetral plant growing from the base of the wall.

In the Gallery

Creek Pool
Shaped by whirlpools during high flow, the curves recall flowing water.

A memorable feature of upper Treman Park is the dramatic gorge entrance.  When the glaciers melted, 10,000+ years ago, enough water flowed through this watercourse to wear away several hundred feed of sedimentary rock to form a gallery, or hall, with towering, crumbling, walls on either side.

This evening the light was low, the water seemed dead in that it was clear and did not glisten or ripple.  I used these conditions in the above shot to emphasize the structure this pool.  Located at the foot of a waterfall, at high water, the falls fill channel and this pool is carved by river stones carried in the current.  At lower water, the pool is exposed.

Foot Bridge
Spanning the eastern side of the gallery entrance of the gorge.

The footbridge, above, is most often photographed from the western side of a long gallery formed by the gorge carved by the creek.  This is a shot that explores the fine stonework.

Mizpah and Mitzvah

I was reading the story of Jacob and Laban and encountered the word “Mizpah” is Hebrew for “watchtower”. It is used to refer to an emotional bond or covenant made between two people with God as their witness, often symbolized by a pile of stones marking an agreement​​. Mizpah sounds similar to “Mitzvah,” often used to mean “a good deed,” and is related to the Aramaic word “tzavta,” which means to attach or join. This term is commonly used to describe any charitable act and has deep roots in Jewish tradition and texts, such as the Jerusalem Talmud.​​

The relationship between “Mizpah” and “Mitzvah” seems to be more linguistic and symbolic rather than direct. Both terms originate from Semitic languages and carry connotations of connection and covenant. “Mizpah” symbolizes a bond overseen by God, while “Mitzvah” refers to actions that connect individuals through good deeds, potentially strengthening communal bonds.

Woodland Goldenrods

Woodland goldenrods in the Finger Lakes Region contribute to ecosystem biodiversity and resilience.

In the Finger Lakes Region of Central New York State, a tapestry of flora unfurls across the landscape, marked by the vibrant yellows of woodland goldenrods. These wildflowers are not just a visual spectacle; they are integral to the ecosystem, contributing to its biodiversity and offering a feast for pollinators.

Woodland goldenrods (Solidago species) are part of a larger genus that encompasses over 100 species, many of which thrive in the varied habitats of the Finger Lakes. This region, with its rich soils, ample rainfall, and diverse topography, hosts an array of goldenrod species, each adapted to specific niches within the woodland understory.

Hint: click image for larger view. Ctrl/+ to enlarge / Ctrl/- to reduce

Solidago caesia, commonly known as blue-stemmed or wreath goldenrod, is one species that graces these woods. Unlike the typical roadside goldenrods, this species thrives in the dappled shade, its delicate arching stems culminating in small bursts of yellow flowers that appear like beaded necklaces draped over the greenery.

Another species, Solidago flexicaulis, or zigzag goldenrod, earns its name from the characteristic bending pattern of its stem, which zigzags between leaf nodes. Its flowers are more clustered, favoring the shade and moist conditions of the forest floor. Its presence is often a sign of a healthy, undisturbed woodland.

Solidago odora, or anise-scented goldenrod, brings a sensory delight to the mix with leaves that emit a licorice-like fragrance when crushed. This goldenrod favors the edges of woodlands and clearings, where sunlight can reach its clusters of tiny, bright yellow flowers.

The downy goldenrod, Solidago puberula, is yet another species that decorates the region’s woodlands. It prefers dry, sandy soils, often found on the slopes and ridges that contour the Finger Lakes. Its name comes from the fine hairs that cover its stems and leaves, a characteristic that distinguishes it from its kin.

Each of these goldenrods plays a role in the woodland ecosystem. Their flowers provide nectar and pollen for a variety of insects, from bees and butterflies to beetles and flies. The seeds are a food source for birds, and the plants themselves offer habitat to numerous woodland creatures.

The presence of woodland goldenrods also indicates the health of the region’s forests. These plants are often pioneers in disturbed areas, contributing to soil stabilization and the natural succession process. They are resilient and adaptable, capable of surviving in a range of conditions from full sun to dense shade, though each species has its preference.

In the Finger Lakes Region, the goldenrods bloom from late summer into the fall, their golden hues a prelude to the coming autumnal display. They stand as a testament to the beauty and complexity of these woodlands, their very existence a reminder of the delicate balance within these ecosystems.

In conclusion, the woodland goldenrods of the Finger Lakes are more than just a splash of color in the verdant forests. They are a vital part of the ecological tapestry, contributing to the biodiversity and resilience of the region. Each species, with its unique adaptations and preferences, adds to the rich natural heritage of Central New York State, reminding us of the intricate web of life that thrives in these woodlands.

Treman Early Autumn Walk XI

Thomas Edison and Henry Ford innovatively used goldenrod to produce rubber, potentially counteracting rubber shortages.

Where the Rim Trail descends to an ending on the Enfield Gorge floor a perennial patch of sunlight promotes an extravagant woodland growth of Zigzag goldenrod.

Solidago flexicaulis, AKA Broadleaf Goldenrod and Ziazag Goldenrod

“Inventor Thomas Edison experimented with goldenrod to produce rubber, which it contains naturally. Edison created a fertilization and cultivation process to maximize the rubber content in each plant. His experiments produced a 12 ft-tall (3.7 m) plant that yielded as much as 12% rubber. The tires on the Model T given to him by his friend Henry Ford were made from goldenrod. Like George Washington Carver, Henry Ford was deeply interested in the regenerative properties of soil and the potential of alternative crops such as peanuts and soybeans to produce plastics, paint, fuel and other products.  Ford had long believed that the world would eventually need a substitute for gasoline and supported the production of ethanol (or grain alcohol) as an alternative fuel. In 1942, he would showcase a car with a lightweight plastic body made from soybeans. Ford and Carver began corresponding via letter in 1934, and their mutual admiration deepened after George Washington Carver made a visit to Michigan in 1937.”

“By the time World War II began, Ford had made repeated journeys to Tuskegee to convince George Washington Carver to come to Dearborn and help him develop a synthetic rubber to help compensate for wartime rubber shortages. Carver arrived on July 19, 1942, and set up a laboratory in an old water works building in Dearborn. He and Ford experimented with different crops, including sweet potatoes and dandelions, eventually devising a way to make the rubber substitute from goldenrod, a plant weed commercially viable. Carver died in January 1943, Ford in April 1947, but the relationship between their two institutions continued to flourish: As recently as the late 1990s, Ford awarded grants of $4 million over two years to the George Washington Carver School at Tuskegee.”

“Extensive process development was conducted during World War II to commercialize goldenrod as a source of rubber. The rubber is only contained in the leaves, not the stems or blooms. Typical rubber content of the leaves is 7%. The resulting rubber is of low molecular weight, resulting in an excessively tacky compound with poor tensile properties.”

Treman Early Autumn Walk X

The zigzag goldenrod is a crucial plant to North American pollinator biodiversity, hosting diverse insects.

After crossing the bridge at Swan Road I turned back down the gorge on the Rim Trail, climbing above the gorge where these interesting woodland goldenrod thrive.

“Solidago flexicaulis, the broadleaved goldenrod, or zigzag goldenrod,is a North American species of herbaceous perennial plants in the family Asteraceae. It is native to the eastern and central parts of the United States and Canada, from Nova Scotia west to Ontario and the Dakotas, and south as far as Alabama and Louisiana. It grows in a variety of habitats including mesic upland forests, well drained floodplain forests, seepage swamp hummocks, and rocky woodlands.”

“The plant is called the “zigzag goldenrod” because the thin, wiry stem zigs and zags back and forth, changing direction at each node (leaf attachment point). The plant bears sometimes as many as 250 small yellow flower heads, some at the end of the stem, others in the axils of the leaves. The leaves are very broad, almost round, but with an elongated tip at the end and large teeth along the edges.”

“Goldenrod is considered a keystone species and has been called the single most important plant for North American pollinator biodiversity. Goldenrod species are used as a food source by the larvae of many Lepidoptera species. As many as 104 species of butterflies and moths use it as a host plant for their larvae, and 42 species of bees are goldenrod specialists, visiting only goldenrod for food. Some lepidopteran larvae bore into plant tissues and form a bulbous tissue mass called a gall around it, upon which the larva then feeds. Various parasitoid wasps find these galls and lay eggs in the larvae, penetrating the bulb with their ovipositors. Woodpeckers are known to peck open the galls and eat the insects in the center.”

“Solidago flexicaulis is host to the following insect induced galls: Asteromyia modesta, a species of gall midges in the family Cecidomyiidae. Gnorimoschema gallaesolidaginis also called the solidago gall moth, goldenrod gall moth or goldenrod gallmaker, is a moth in the family Gelechiidae.”
