Cardamine diphylla: A Woodland Marvel

Step into the spring woods and discover the broadleaf toothwort, Cardamine diphylla. Marvel at its white blossoms and deep-lobed leaves, and uncover its vital role in both early pollination and traditional medicinal practices.

MichaelStephenWills3 Comments

Broadleaf toothwort, Cardamine diphylla, plays a charming role in the ecosystem of deciduous forests, often carpeting the forest floor with its distinctive greenery and white blossoms during the spring. This plant is particularly noted for its broad, compound leaves that usually consist of two or three leaflets, each characterized by deep lobes and a somewhat wrinkled appearance, lending it the name “crinkle root.”

The flowers of the broadleaf toothwort are a notable feature, emerging in clusters atop slender, upright stems. Each bloom presents four white petals that form a delicate cross, a typical trait of the Brassicaceae family, to which it belongs. The flowering period spans early to mid-spring, making it one of the earlier blooms in woodland areas, which plays a critical role in the local ecology. These flowers are not just a visual treat but are also vital for early-season pollinators such as bees and butterflies, providing them with necessary nectar.

Moreover, Cardamine diphylla is more than just a visual and ecological gem. It has historical uses in traditional medicine and cuisine. Native American tribes utilized the peppery roots of the toothwort as a seasoning and as a medicinal herb to treat various ailments.

The presence of Cardamine diphylla is also an indicator of the health of the forest ecosystem. Thriving populations of this plant suggest a well-preserved habitat, which is crucial for biodiversity conservation.

In summary, Cardamine diphylla, with its ecological significance and historical uses, represents a small but vital part of North America’s natural heritage, highlighting the intricate connections within woodland ecosystems and the importance of preserving these natural environments.

Hatch, Birth, Good Luck!

If you ever feel like you’re struggling with independence, just remember these creatures who start life with the ultimate “figure it out yourself” kit.

MichaelStephenWills12 Comments

Introducing the “Self-Service Buffet” of the animal kingdom, where the motto is “Hatch, Birth, Good Luck!” These creatures don’t stick around for cuddles or parenting classes:

Sea Turtles – The Ultimate Sand Sprinters: These little guys burst from their eggs and make a mad dash for the ocean, dodging seagulls and crabs. It’s like the world’s most stressful obstacle course, where the prize is simply survival.

Salmon – Swimmers on a Solo Mission: After hatching, young salmon are on their own, navigating the perilous waters without a GPS or even a pep talk. They’ve got more instinct in their little fins than most of us have in our entire body!

Praying Mantises – The Loner Ninjas: These insects hatch ready to rumble, with no parental guidance on how to be the ultimate predator. It’s a tough world where your siblings might just see you as their first meal. Talk about family drama!

Kangaroo Rats – Desert Hoppers Inc.: Born in the harsh desert, these tiny rodents are all about the solo journey from the get-go. No room service or guided tours here; just a lot of hopping and hoping.

Octopuses – The Brainy Solitaires: Octopus moms are the epitome of “do it yourself,” laying their eggs and then, well, signing off. The babies hatch fully equipped with all the smarts and skills they need, making them the envy of every overbooked parent.

Komodo Dragons – The Scaly Independents: These formidable lizards hatch ready to take on the world, with a fierce look in their eye that says, “I didn’t choose the dragon life, the dragon life chose me.”

Butterflies – The Winged Wanderers: From caterpillar to chrysalis, and then to butterfly, these creatures do it all on their own. If butterflies had social media, their status would perpetually be “Just transformed. Who dis?”

Tidal Wetlands

MichaelStephenWills9 Comments

The exposed mudflats on tidal wetlands attract a variety of shorebirds. Shorebirds are seasonal residents that make long migratory journeys between their breeding grounds in the Arctic and their wintering areas in South America. Merritt Island NWR provides an important resting and feeding area for this group of birds. Some stay for the winter, and others use the refuge as a fuel stop before continuing on their journey.

In tidal areas, shorebird feeding schedules are influenced by the cycle of the tides. Changes in tidal cycles expose foraging areas in mudflats for a period during the day. At other points during the cycle, the water in these same areas becomes too deep or the ground too dry for shorebirds to feed effectively.

Shorebirds of different species can and do forage together. Because bill length and shape varies from species to species, birds can pursue different prey in the same area at the same time without competing with each other. Because of varying bill lengths, the different bird species find their food at different depths in the substrate. Mixed species of shorebirds are a common sight.

Encounter with Helianthus debilis


Strolling along the beachfront of Patrick Space Force Base, Florida, my gaze is captivated by a cluster of dune sunflowers, or Helianthus debilis. These hardy perennials are native to the coastal sand dunes of the southeastern United States and have made a home amidst the sandy grains where few dare to take root.

The Sunflower’s Domain


Helianthus debilis, distinguished by its large, yellow ray florets and dark center disks, thrives in this challenging environment. The dunes provide a unique ecosystem, where the sunflowers can withstand high salinity, shifting sands, and the full force of the sun’s rays. Their deep root systems anchor the sandy soil, helping to prevent erosion and maintain the integrity of the dune landscape.

Adaptation and Survival


The dune sunflower’s adaptation to its coastal environment is a marvel of nature. Its silvery-green leaves are covered with tiny hairs, reflecting sunlight and conserving moisture. The flowers bloom throughout the year, ensuring a constant presence of color along the dunes. Their hardiness is a testament to the sunflower’s evolutionary success in a habitat where freshwater is scarce and the soil is nutrient-poor.

A Native’s Role in the Ecosystem


As a native species, the dune sunflower plays a crucial role in the coastal ecosystem. It serves as a food source for local wildlife, including insects and birds, and its presence helps stabilize dune formations. The ecological value of Helianthus debilis extends beyond its beauty, as it contributes to the biodiversity and resilience of the coastal dunes.

The Dynamics of Dune Life


The life of a dune sunflower is inextricably linked to the ebb and flow of the coastal environment. Each plant is a microhabitat, supporting a range of organisms from the larvae of the dune butterfly to the burrowing beetles that find refuge in the sand. The interaction between the sunflowers and these creatures creates a dynamic web of life, each species depending on the others for survival.

Reflections on Resilience


The dune sunflower’s ability to flourish in such an austere environment is a profound reminder of the resilience of nature. As I observe the sunflowers, I am struck by their tenacity, their willingness to face the elements head-on. They are a beacon of life in a place where existence is a daily challenge, and their perseverance is a lesson in the art of endurance.

Conclusion: A Testament to Nature’s Ingenuity


As the sun begins to set, casting a warm glow over the dunes, I take a final look at the Helianthus debilis. Their scientific wonders and ecological im portance leave a lasting impression. They are not just flowers; they are a testament to nature’s ingenuity, an embodiment of the delicate balance between life and the environment. These dune sunflowers are a symbol of hope, a reminder that in the face of adversity, life finds a way to not just survive, but to thrive.

Treman Early Autumn Walk XIV

The post discusses the Hepatica acutiloba plant, highlighting its characteristics, growth, historical medicinal use, and its natural habitat in central eastern North America. It also includes an observation made in Robert H. Treman Park.

MichaelStephenWills2 Comments

These characteristic leaves are Hepatica plants growing on the sun dappled southern rim of Robert H. Treman Park captured on a bright late September morning.

“Hepatica acutiloba, the sharp-lobed hepatica, is a herbaceous flowering plant in the buttercup family Ranunculaceae. It is sometimes considered part of the genus Anemone, as Anemone acutiloba, A. hepatica, or A. nobilis. Also generally known as Liverleaf and Liverwort.”


“The word hepatica derives from the Greek ἡπατικός hēpatikós, from ἧπαρ hêpar ‘liver’, because its three-lobed leaf was thought to resemble the human liver.”


“Each clump-forming plant grows 5 to 19 cm (2.0 to 7.5 in) tall, flowering in the early to mid spring. The flowers are greenish-white, white, purple or pinkish in color, with a rounded shape. After flowering the fruits are produced in small, rounded columned heads, on pedicels 1 to 4 mm long. When the fruits, called achenes, are ripe they are ovoid in shape, 3.5–4.7 mm long and 1.3–1.9 mm wide, slightly winged and tend to lack a beak.”

Hepatica Flowers in early spring on the Rim Trail

“Hepatica acutiloba is native to central eastern North America where it can be found growing in deciduous open woods, most often in calcareous soils. Butterflies, moths, bees, flies and beetles are known pollinators. The leaves are basal, leathery, and usually three-lobed, remaining over winter.”

“Hepatica was once used as a medicinal herb. Owing to the doctrine of signatures, the plant was once thought to be an effective treatment for liver disorders. Although poisonous in large doses, the leaves and flowers may be used as an astringent, as a demulcent for slow-healing injuries, and as a diuretic.”

Treman Early Autumn Walk X

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

MichaelStephenWills6 Comments

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.”

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.
