Zinnias for Butterflies–– and the Kitchen Table Sowing the Seeds of the Future Butterfly Garden Journal:

Common and Uncommon Butterflies in the North Woods

Wanted Alive in Your Garden: Pipevine Swallowtail Caterpillar

editor's notes On a sunny day in early fall, as I walk the fifty steps from my front door to the garage I might count a dozen butterfly species. It is true that I often walk very slowly, stopping along the way to watch the butterfly activity, taking twenty minutes to get to the car rather than one.

Over the years I have learned what nectar plants work in my garden to draw in butterflies and I grow these A-list plants along the path I walk daily. Zinnias, Eastern Purple Coneflower, Purpletop Vervain, and Phlox ‘Jeana’ provide flowers from June until frost, ensuring that I will consistently be late for appointments many months of the year.

Zinnias for Butterflies--and the Kitchen Table Photos and Text by Gary Noel Ross, Ph.D.

The garden-variety zinnia has been around for a long time. You know, those large colorful flowers that were a mainstay of summer cottage gardens, and when cut and placed into a vase, were a showy centerpiece for the kitchen table?

Well, the zinnia is still going strong. And for butterfly aficionados, the plant is now recognized as a numero uno component of a pollinator garden—even in highly urbanized landscapes. In fact, I dare say that zinnias are the hardest-working flowers in the summer garden of any size.

So, what is this super plant?

The zinnia belongs to the aster family. Hallmarks include multi-petals arranged in a starburst pattern, as the name “aster” implies; centers are usually open to accommodate the reproductive stamens and pistils. Several species are native to the drier regions of the U.S., Mexico, and Central and South America. (By the way, the name zinnia honors the eighteenth-century German anatomist and botanist Johann Gottfried Zinn.)

Although wild plants produce flowers that are small, single, and usually restricted to yellow and orange, hybrids can reach the size of a saucer and sport colors that span the spectrum—except for blue. Flower shape is always circular, of course. But the petals can vary from a single whorl to multi-tiers, to even “pompomesque.” But for pollinators, the fewer the petals, the more reproductive structures (pistils and stamens), and hence, more nectar and pollen.

Over the years, horticulturists have tweaked the genetics of two wild zinnias (Z. elegans and Z. augustifolia, both native to Mexico) by cross-pollinating. The goal has been to create plants that are more robust and more resistant to moisture in both soil and air. (Historically, excessive moisture tends to foster mildews that create powdery leaves and brown leaf spots. For that reason, zinnias inherently thrive best in climes that have rainfall below 40 inches per year and where nighttime temps routinely drop below 70 degrees F.) Today, scientific diligence has produced several varieties that are relatively tolerant to the sultry days and nights of even the Deep South, and like their ancestors, still resistant to heat and drought.

Zinnias can be separated into two basic categories: tall and spreading. First, the tall. I have found that here in the Deep South, the variety known as “Benary’s Giant Mix” does best. Up to three or four feet in height, the plants are topped by large flowers in a seemingly endless variety of colors and shapes—all with long stems. Swallowtails are particularly drawn to the flowers since the massive flower heads serve as excellent landing platforms. Two cautionary notes: First, Benary’s are subject to mold. I compensate by discarding my plants in early August. I then sow another set, and that guarantees a showcase bloom all the way until frost. And second, because of their height, Benary’s often succumb to the wind. But this can be offset by planting in dense clusters or near a wall.

Great Southern White on compact, dwarf "Zahara" series, a mildewresistant cultivar for the South

One of the oldest spreading varieties is the “Crystal” series featuring “Crystal White,” “Star Gold,” and “Star Orange.” These are narrow-leaf forms that resemble their wild ancestors. Plants remain short but tend to become rather leggy. Flowers are small, single, and open. These plants are especially attractive to small butterflies such as skippers.

The most popular spreading zinnias are the “Profusion” and “Zahara™” series. Both are lowgrowing, compact, and produce medium-sized, tight flower heads in a wide range of color— “Zahara” more so than “Profusion.” In addition, flowers of “Zahara” exhibit less fading with age.

Both series are noticeably resistant to mildews. Another advantage: no need to deadhead. Fresh flowers attract butterflies of all sizes.

But whichever variety you select, butterflies and other insect pollinators will be “magnetized.” As a lagniappe, all varieties are easily started from commercially available packets of seed or seeds that you reserved from your previous year. Just make sure your flower beds are in full sun and filled with loose, well-drained soil. And NEVER OVERWATER since zinnias are highly tolerant of drought conditions. One last point: fertilize when the plants are young, but then back off. Excessive nitrogen stimulates vegetative growth with a reduction in flowers. Bottom line, respect the zinnia’s heritage and you will be rewarded with an abundance not only of flowers but also of butterflies and other pollinators.

Sowing the Seeds of the Future Text and Photos by Ellen Federico

When the children on Fire Island scatter milkweed seeds in fall, they do it with high expectation because they know that, if we plant the seeds, the Monarchs will come.

Fire Island is a barrier island three miles south of Long Island, New York, and a super flyway for migrating Monarchs that glide our dune thermals, lay eggs on native milkweed, nectar on flowers, and sip salt from sand. This summer our Common Milkweed is abundant and tall, waving orbs of fragrant blossoms to attract the royal Monarch butterfly.

Carl Linnaeus first identified the genus and named it Asclepias after the Greek god of healing. Its common name, milkweed, refers to the milky latex sap that is exuded when a stem or leaf is broken.

Native Americans used milkweed sap to remove warts and the roots were steeped to treat pleurisy.

Today medical researchers are studying milkweed in the fight against cancer and organic farms in the Midwest are growing milkweed to extract the oil in seeds as a topical remedy to relieve arthritis, asthma, and muscle pain.

In Lonelyville, a small beach community on the western end of Fire Island, our Monarch habitat is planted with Common and Swamp Milkweeds in addition to nectar plants such as Mexican sunflowers, Nippon Daisies, and Alpine Asters. Towering above the milkweed and other flowers, an abundance of cedar trees offer perfect overnight roosting so the migrating Monarchs can rest on their long journey.

The local children are avid citizen scientists who help tend the habitat. Our goal is to engage neighbors to sow Common Milkweed seeds gathered from established plants and scatter the seeds across 5000 acres of Fire Island grasslands. This is an excellent activity for families, schools, or community social gatherings.

Use caution when handling milkweed. The milky sap that seeps from broken stems and leaves can cause skin irritation.

When the shadow of a butterfly crosses our path, we look up by some silent command and our spirits lift. The extraordinary migration of Monarch butterflies reminds us how precious they are, and the safety of their future lies in our hands. If seeds contain genetic information to produce tomorrow’s promise of new growth, so do our children.

An educated flutter can heal the world.

Ellen Federico operated a successful corporate meeting planning firm in Manhattan for 32 years. Now she travels, writes, and maintain a Monarch habitat in Fire Island, New York.

Common and Uncommon Butterflies in the North Woods Text and Photos by Allison Snopek Barta My garden keeps growing and the butterflies keep arriving. This summer I was really surprised to discover an Appalacian Brown in my yard and garden. This was a first time sighting in my garden––I usually only see this species in swampy areas about two miles from my house. It apparently flew up from a nearby swamp, liked my garden better, and stayed.

Later in the summer I was shocked to have another first time sighting in my garden. While mowing our yard I came across a Harvester! It is rare for me to find this species in any of my usual observation locations here on Oak Point, Minnesota. If you find one I hope you get some Butterfly Gardener www.naba.org

photos because it is an uncommon sighting.

Much to my surprise I saw two in our yard, and another individual in a yard of a nearby neighbor. With some effort, I was able to get a nice photo of it on a beet leaf in my garden.

As of September 1st, I've seen and photographed 29 species in my flower garden this summer and enjoyed watching Monarch caterpillars grow and emerge as adult monarchs.

With summer coming to an end, the Monarchs left on their journey south and I thought the butterfly season was over. But much to my surprise more than 50 Painted Ladies arrived over Labor Day weekend turning my garden into a Butterfly Show! What a joy to see them all!

I was so surprised to see so many Painted Ladies in my flower garden, that I got in my car and drove all around Oak Point to see if this phenomenon was occurring anywhere else. It wasn’t. At each observation site I only saw a few Painted Ladies. I wonder what will happen next in this flower garden I built ?

Allison Snopek Barta is a lifelong advocate of butterflies. She has been recording her Minnesota butterfly observations for many years and has compiled her sightings into a presentation titled “On the Hunt for the North Woods Butterflies.” She hopes to publish her photos and observations after finding and photographing just two more species (Olympia Marble and Red-disked Alpine), which will bring her total observations to 90 species for northern Minnesota.

Pipevine Swallowtail Caterpillar Text and Photos by Jan Dixon Special weaponry: Pipevine Swallowtail caterpillars sequester aristolochic acids from their food plants. These toxins protect them from predators through the rest of their life cycle, from caterpillar to pupa to butterfly, and even to the eggs of the next generation. The thick outer layer of the caterpillar’s exoskeleton resists damage from pecks and bites while releasing a bitter-tasting liquid that is an effective deterrent to attackers.

The caterpillars are quite gregarious in the early stages of development. They hang out in groups, subscribing to the “safety in numbers” philosophy of defense.

Like other swallowtail caterpillars, those of Pipevine Swallowtail can evert osmeteria from their heads that release offensive chemicals when the caterpillar feels threatened.

Known disguises:

Pipevine Swallowtail caterpillars are usually dark brown to black, although a dark-red form does occur as well. Bright-orange rounded projections (called tubercles) run in rows along the body, sending a signal to possible predators that “I don’t taste good!”

Known Food Preferences: Pipevine Swallowtail caterpillars feed on many plants in the genus Aristolochia (Dutchman’s Pipe).

While there are many native Dutchman’s Pipe species to choose from, many of the tropical Dutchman’s Pipes are toxic to Pipevine Swallowtail caterpillars, although females may lay eggs on these species.

Native Dutchman’s Pipe species that support Pipevine Swallowtail caterpillars Pipevine (Aristolochia macrophylla) Woolly Dutchman’s Pipe (Aristolochia tomentosa) Texas Dutchman’s Pipe (Aristolochia reticulata) California Dutchman’s Pipe (Aristolochia californica) Virginia Snakeroot (Aristolochia serpentaria) Tropical Dutchman’s Pipes that are toxic to Pipevine Swallowtail caterpillars Elegant Dutchman’s Pipe or Calico Flower (Aristolochia elegans) Giant Dutchman’s Pipe (Aristolochia gigantea)

If capture is avoided: The caterpillar usually leaves its food plant for a suitable site for its next phase, pupation. Pupae can be green or brown, depending on the surface to which they are attached, and are often placed off the ground on tree trunks. There are two generations in the northern part of its range, 3 or more in the southernmost part. Pupae overwinter, with a new generation of butterflies emerging in spring.

The Pipevine Swallowtail has a wide distribution across the United States, from southern Connecticut and New York west to southern Nevada, and south to Florida and Mexico. It may stray further north.

This beautiful swallowtail can be found in woodlands, meadows, and backyard gardens where the host plant is found.

Jan Dixon enjoys observing caterpillars, almost as much as adult butterflies, and has raised ten species from her gardens. She volunteers as a butterfly monitor at the Nature Conservancy’s Kitty Todd Preserve in Northwest Ohio and is on the board of the Oak Openings Region chapter of Wild Ones. She also enjoys teaching about butterfly gardening.
