Monarch Chrysalis: A Symbol of Nature’s Resilience

On a September day, a Monarch chrysalis symbolizes resilience amidst environmental threats, prompting reflection on stewardship and hopeful change.

On a warm September afternoon, 2024, Pam and I passed a planting of shimmering grasses along the Cayuga Lake shore, the tips of their feathery plumes swaying in a gentle breeze. Amidst the verdant tapestry, my eyes caught a flash of delicate green—a Monarch chrysalis, hanging like a precious jewel beneath one of the seed heads. It was an unexpected encounter, a moment of grace that felt almost otherworldly. The chrysalis, pale jade with gold accents, looked like something born of magic rather than biology. For a moment, time paused.

I knelt carefully, mindful not to disturb the fragile life suspended before me. As I leaned in closer, I marveled at the perfection of its design. The intricate gold dots along its casing seemed impossibly precise, as though a divine hand had painted them there. Yet, this chrysalis was also a paradox: it was a shield of stillness, promising the coming transformation of a creature known for motion and migration.

The significance of this discovery didn’t escape me. Just two years ago, the International Union for Conservation of Nature officially classified the Monarch butterfly as “endangered.” Habitat destruction, pesticide use, and climate change have decimated their numbers. Monarchs, once so plentiful they seemed a seasonal certainty, now teeter on the edge of disappearance. To find this chrysalis was to witness a quiet rebellion against those odds, a solitary emblem of resilience in a world fraught with loss.

I thought of their epic journey—a migration that spans thousands of miles, linking Canada to the forests of central Mexico. For generations, these butterflies have followed ancestral paths with unerring precision, defying every obstacle in their way. How can something so small carry the weight of such immense journeys? And how, in a world that seems to grow harsher each year, do they still persist?

This chrysalis, tucked in the grasses of Stewart Park, felt like an answer to those questions. It was a reminder of the resilience of life, the determination of nature to continue despite all that works against it. And yet, it also felt like a fragile promise. The Monarch’s survival is no longer assured; its future, like the butterfly within this chrysalis, hangs by a thread.

As I rose and continued our walk, I carried the image of the chrysalis with me, letting its quiet beauty settle in my mind. I thought of the interconnectedness of all things: the milkweed plants that sustain Monarch caterpillars, the winds that guide their migrations, and the people whose choices shape the landscapes they traverse. Stewardship is not just a responsibility; it is a privilege—an opportunity to ensure that these miraculous creatures continue to grace our skies.

By the time I left the park, the sun had sunk toward the west, its light no longer graced the grasses. I looked back one last time, hoping that this chrysalis would complete its transformation safely. In its stillness, I saw not just hope, but a call to action. The Monarch’s story is not just about survival; it’s about the courage to evolve and adapt, even when the odds seem insurmountable. And perhaps, in witnessing this moment of metamorphosis, we too are reminded of our capacity to change—to become better stewards of the world we share.

Farewell to the Monarchs for 2023

Monarch from caterpillar to chrysalis to butterfly

MichaelStephenWills6 Comments

Here are two of the ten monarchs we release this year. In under three minutes this video shows a monarch caterpillar transforming into a chrysalis, emerging two weeks later as a butterfly. Music “Emotional Underscores Vol. 3” by Yuri Sazonoff (SOCAN) “Can You Guess” and “Blessing”

“Migrating monarchs soar at heights of up to 1,200 feet. As sunlight hits those wings, it heats them up, but unevenly. Black areas get hotter, while white areas stay cooler. The scientists believe that when these forces are alternated, as they are with a monarch’s white spots set against black bands on the wings’ edges, it seems to create micro-vortices of air that reduce drag—making flight more efficient.”

“Monarchs begin leaving the northern US and Canada in mid-August. They usually fly for 4-6 hours during the day, coming down from the skies to feed in the afternoon and then find roosting sites for the night.  Monarchs cannot fly unless their flight muscles reach 55ºF. On a sunny day, these muscles in their thorax can warm to above air temperature when they bask (the black scales on their bodies help absorb heat), so they can actually fly if it is 50ºF and sunny. But on a cloudy day, they generally don’t fly if it is below 60ºF.“

“Migrating monarchs use a combination of powered flight and gliding flight, maximizing gliding flight to conserve energy and reduce wear and tear on flight muscles.  Monarchs can glide forward 3-4 feet for every foot they drop in altitude.  If they have favorable tail or quartering winds, monarchs can flap their wings once every 20-30 feet and maintain altitude. Monarchs are so light that they can easily be lifted by the rising air. But they are not weightless. In order to stay in the air, they must move forward while also staying within the thermal. They do this by moving in a circle. The rising air in the thermal carries them upward, and their overall movement ends up being an upward spiral. Monarchs spiral upwards in the thermal until they reach the limit/top of the thermal (where the rising air has cooled to the same temperature as the air around it). At that point, the monarch glides forward in a S/SW direction with the aid of the wind. It glides until it finds another thermal and rides that column of rising air upwards again.”

First Release of 2023

Advice for releasing your monarch butterfly

MichaelStephenWills2 Comments

We let our first monarch butterfly rest overnight, until noon of the following day.

Pam did better with tracking the monarch’s flight, so I used video. Thanks Pam!

I delay butterfly release when:

  • the forecasted high temp is below 65° F (18° C) or 60° F (16° C) if sunny and calm.  When no other option exists, 50-59° F and sunny is borderline acceptable.
  • the forecast calls for rain.  A light rain is not a problem for butterflies with day-old dry wings, but it’s not a good release option for first-day newborns.
  • the butterfly emerges too late in the day.  I keep it overnight if the butterfly cannot get 3 hours warming of flight muscles in the sun.
  • there are storms in the forecast.  I wait when there are less than four (4) hours of good weather projected.  When extreme weather (like a hurricane) is forecast within twenty four (24) hours, I keep the butterfly safe until the storm passes.  Twenty four (24) or more hours should provide ample time to find shelter from the storm.
  • I am not sure about a release.  Keeping a butterfly overnight is acceptable. In fact, a butterfly’s wings are stronger on day two (2), providing better capability to escape predators.  A butterfly can easily hang from the mesh cage roof overnight. I do not worry about feeding a butterfly unless a second night of shelter is necessary.

As the moment of emergence approaches, the skin of a Monarch chrysalis becomes translucent to reveal the butterfly compressed into that small space.

First Emergence of 2023

Monarch butterfly and chrysalis

MichaelStephenWills3 Comments

Our grandchildren spent the day with us, the last week of their summer before school begins. This July I had improved on my Monarch collection from 2022, when 9 butterflies were released, by two (2) caterpillars for a total of eleven (11) raised over several weeks to the chrysalis stage. When leaving to pick up the children for an outing one chrysalis skin had turned clear, a sign the enclosed butterfly is close to emerging. We returned from an outing for lunch to find this chrysalis unopened, so we checked now and then for progress. Four hours later, just as their Mom arrived for them, the grandchildren and everyone witnessed this event. What luck!!

Climb to Gorge Trail

Potential danger abounds

MichaelStephenWills10 Comments

Capturing photographs and videos on the fly using an Iphone, we visited Fillmore Glen State Park, Moravia, New York with our granddaughter, Nia. This is the third post of this series. Click me for the first post in this series.

Emerging from the blind canyon of Cowsheds Waterfall, we are faced with this gorgeous pool fed by Dry Creek (yes, that is the name). Formed by a dam, the water is deep and very cold.

We were standing on this footbridge for the above photograph. The trail to Cowsheds is on the far side of Dry Creek and to the right.

We have yet to count these steps, don’t know why. The limestone blocks were quarried locally from the same stone of the creek bed. The gorge trail begins at the top.

Trillium Seed Capsule

This is a Purple Trillium, I believe, formal name Trillium erectum. It is a large specimen judging form the width of the bracts, leaf like structures at the based of the flower stalk. When fertilized, the ovaries form this seed capsule containing up to 16 seeds, each with lipid with a high content of oleic acid. During summer, the capsule opens, seeds disperse. Ants encounter the seed elaiosome, the oleic acid content triggers “corpse carrying behavior.” The ants carry the seeds into their nests, consume the lipids leaving the seeds. After a year dormancy the seeds sprout and the additional depth in the ant nest provides a good start.

Trillium are a favorite food of deer, unfortunately. Some seeds are spread this way, passing through the digestive tract and out in fecal waste. I use the color of the seed capsule to identify it was Purple Trillium. In my experience the white variety (Trillium grandiflorum, and others) has a light colored seed capsule.
