The Fortunate Visit of a White Monarch Butterfly

Life on a remote island in the South Pacific brims with quirky surprises. We learn to expect most anything.

While driving to town, the random pig will dash in front of the car, causing us to slam on brakes. Sometimes, it’s a dozen pigs, or a pair of dogs, or a clutch of chickens; or a child, who seems to delight in the cheap thrill of racing across the road and living to laugh about it.

I live in Nuku‘alofa on the island of Tongatapu in the Kingdom of Tonga, which is 1,240 miles (1,997 kilometers) northeast of Auckland, New Zealand. A few days ago, a white Monarch butterfly (Danaus plexippus nivosus) found the Tropical Milkweed (Asclepias curassavica) in my yard and began laying eggs.

I thought her wings were just old, worn, and faded, as butterflies can get as they age. But, on closer inspection, I realized that she was actually white in the places where she should have been orange. We have Monarch butterflies here in Tonga (read more here), but this is the first white Monarch that I’ve observed anywhere.

According to Monarch Watch, white Monarchs have been found throughout the world, including in Australia, New Zealand, Indonesia, the Hawai‘ian islands and on the mainland of the United States. Generally, white Monarchs are extremely rare with only a few being reported each year. The exception is in Hawai‘i where it is believed that as much as 10% of the population of Monarchs is white.

White and Orange Monarch Butterflies

White and orange Monarch butterflies side-by-side for comparison.

Monarchs are preyed upon by birds called Red-Vented Bulbuls (Pycnonotus cafer), which are quite abundant here on our island, as well as in Hawai‘i. Red-vented Bulbuls come from Southeast Asia and are relative newcomers to the islands of Polynesia.

Scientists suggest that predation is lower for white Monarchs and raise the possibility that the white form is more cryptic (harder to see) for the Bulbuls than the orange form. Consequently, they eat more regular, orange-form Monarchs than white-form specimens, increasing the relative frequency of the latter in places where both white-form Monarchs and Bulbuls range.

As I attempted to get a photo of the white Monarch, a huge Wasp (Hymenoptera apocrita spp.) was flying around which made me nervous, and an aggressive male Blue Moon butterfly (Hypolimnas bolina) kept chasing her away as he displayed his natural territorial tendencies. I realized it was going to be impossible to get a good photograph. So I caught her with my butterfly net and placed her inside a pop-up cage with some Milkweed (Asclepias spp.).

After an overnight stay for observation, I released the white Monarch the next morning. She left me many eggs on the Milkweed in the cage, even laying on the screen, so I thanked her and set her free.

To my surprise and delight, she lingered all day in the garden and continued to come back, time and again, to nectar on the flowers and deposit eggs on the outside Milkweed. I sat on the porch and enjoyed watching her glide gracefully through the air as she flew back and forth in my yard.

Some cultures believe that a white butterfly brings good fortune. I don’t know about any fortune. However, the visit of this beautiful white Monarch brought me great joy and surprise. For that, I’m rich.

Tongan Monarchs

The Kingdom of Tonga is known for its monarchs, including King Tupou VI, the current sovereign and sixth reigning royal since the constitutional monarchy was founded in 1875.

Queen Sālote Mafile‘o Pilolevu Tupou III is perhaps the most famous Tongan monarch of all. She was the first queen regnant and third monarch of the Kingdom of Tonga, an island nation in the South Pacific Ocean. Queen Sālote ruled nearly 48 years, from 1918 until her death in 1965, longer than any other Tongan monarch.

Queen Sālote brought Tonga to international attention when, during her only visit to Europe, she attended the 1953 coronation of Queen Elizabeth II in London.

During the coronation procession, it began to rain and hoods were placed on the carriages of dignitaries in the procession. Since Tongan custom dictates that one should not imitate the actions of the person being honored, she refused a hood and rode through the pouring rain in an open carriage, endearing herself to spectators along the parade route as she smiled and waved.

But long before modern Tongan kings and queens, there was another monarch that came to Tonga: the Monarch (Danaus plexippus) butterfly.

Map of Oceania

Where in the world is Tonga? The Tongan islands lie east of Australia and northeast of New Zealand in the South Pacific Ocean.

Monarch butterflies were first recorded in Tonga in 1863. It’s believed these butterflies flew or were blown thousands of miles to Hawai‘i from North America (or maybe they were serendipitously transported on ships, which seems more likely) and adapted to eat Crown Flower (Calotropis gigantea) leaves instead of leaves of Milkweeds (Asclepias spp.). They spread south through the islands of Polynesia to Tonga.

I started raising Monarch butterflies in Tonga in mid-June of this year when female Monarchs deposited eggs on Tropical Milkweed (Asclepias curassavica) that I’d planted in pots. After two weeks, I had so many caterpillars I knew that I would soon run out of Milkweed for them to eat.

Crown Flower plant has thick stems and leaves. These latter provide excellent forage for hungry Monarch butterfly caterpillars. Their colorful blossoms emit a jasmine-like scent, heady stuff in a tropical paradise. Shrubs can grow up to 15 feet (4.6 m) high.

While driving down a street near my home, and to my utter delight, I discovered the largest Crown Flower tree that I’ve ever seen. This beautiful plant is called Crown Flower because the purple flowers were favored by Hawai‘i’s last monarch, Queen Lili‘uokalani, who considered them a symbol of royalty and wore them strung into delicate leis.

Realizing that I’d found the mother lode of food for my caterpillars, I parked the car and walked to the gate where I called out “Mālō e lelei!” (“Hello!” in Tongan) to see if anyone was home. A five-year-old boy came to the fence. To my dismay, he didn’t speak any English. I pulled out a couple of Tongan pa‘anga (worth about 45 U.S. cents each) and pointed to the tree. He let me inside the yard and I walked over to the tree, cut some branches off and gave the boy the money. He smiled, then grinned, and exclaimed, “Mālō!” (“Thank you!”).

A few days later I retuned, called out again, and the little boy came running to open the gate and let me inside the yard. He was more than willing to take a few more pa‘anga off my hands.

Monarch Chrysalises Hanging from a Porch Railing

Monarch butterfly chrysalises, also known as pupae, hanging below a shell collection and the banister railing on my front porch.

I was able to raise about 70 Monarch butterflies in that brood. Some pupae I hung on the underside of the railing on my porch; others I gave away to teachers, children, and friends. What joy to be rearing Monarchs again!

Crown Flower Tree

By August, I had not been back to the Giant Milkweed tree (another name for Crown Flower) since early-July. My husband and I had left Tonga for a month to visit family and friends abroad. Upon our return, the entire crop of Tropical Milkweed growing in pots on our front porch was completely gone and all of the dozens of chrysalises hanging from the railing had opened. There had been no sign of Monarch butterflies at our house since we returned.

A female Monarch will use her feet to drum on a plant and “taste” its juices. This helps her decide if the leaf would be edible for her caterpillars and, therefore, if she has found a suitable place to lay eggs.

Yesterday, just out of curiosity, I drove by the giant Crown Flower tree and was stunned to see that many of the leaves were gone. I parked the car, walked to the gate and called out, but no one answered. The next-door neighbor informed me that no one was home. However, since the gate was left open, he thought it was okay for me to enter the yard. (He recognized me from previous trips.)

Monarch Chrysalises Hanging on Crown Flower

Beautiful jade-green Monarch chrysalises hanging from the giant Crown Flower tree.

As I approached the tree, I saw several female Monarchs laying eggs at the top where there were still some leaves. Fourth- and fifth-instar caterpillars were everywhere. I ran back to the car to get a plastic bag and began collecting as many caterpillars as I could reach.

Then I realized that there were also chrysalises all over the tree. I was truly giddy! It felt like I was a child waking up on Christmas morning to find presents under the tree. This Christmas tree was covered in beautiful gold-lined green ornaments!

As I looked closer I saw that there were also chrysalises on the ground. When the leaves dried up they would fall off of the tree, or as a caterpillar chewed the leaves, the chrysalis had nothing to support it and it would fall. I decided that I needed to rescue all the chrysalises that I could.

I collected what I was able to find and reach. I also cut some branches that still had leaves on them so I would have food for the dozens of caterpillars that I had collected.

Before long, the little boy came running down the street in his school uniform. He was so happy to see me. I gave him a few pa‘anga coins in exchange for my gleanings.

As I left to take my bounty of butterflies home, we were both smiling and waving like Queen Sālote in London. More than half a century separated us in age, the boy and me. We couldn’t speak each other’s language. But we were a pair of happy Tongan monarchs: he, the king of the magic money tree; I, the queen of butterflies.

“See you again soon, Your Royal Highness!”

“Blue Moon, You Saw Me Standing Alone”

“Blue moon,
You saw me standing alone
Without a dream in my heart
Without a love of my own.”
–Frank Sinatra, First Verse

Graceful Blue Moon (Hypolimnas bolina) butterflies dance in our garden with elegant dress here in Tonga in the South Pacific. Males all appear the same. However, the females are not only dimorphic (featuring different colors and patterns from the opposite sex), but also rarely look the same as other females, demonstrated by this photo essay.

Male Blue Moon Butterfly - Ventral View

With wings folded, this photo shows the male Blue Moon’s ventral view, the underside of its wings. As with most butterflies, its wings at rest are not nearly as showy as the dorsal or topside wings shown in the next photo, Blue Moon males are extremely territorially and will chase away other butterflies, even those larger than themselves.

Male Blue Moon Butterfly

Behold this gorgeous, velvety male Blue Moon butterfly, also known as Great Eggfly. I reared this one and dozens of others like him from caterpillars discovered growing on roadside weeds here in Tonga. The upper side of the wings of the male Blue Moons is jet black, offset with three pairs of white spots: two on the forewing and one on the hindwing. These spots are surrounded by purple iridescence that only appears when the light source is at the correct angle.

Female Blue Moon

The female Blue Moon butterfly has several different colorations. I’ve raised at least 20 females and each one has had different markings. The wings remind me of the colors and patterns of tapa cloth found in Tonga and in other parts of Polynesia. In fact, we’ve started referring to the female Blue Moon butterfly as the Tapa Cloth butterfly. I suppose that’s how butterflies get their common names.

Tapa Cloth

This is a typical piece of finished tapa cloth or ngatu (pronounced NAH-too) in Tongan. Tapa cloth is made from the inner bark of the Mulberry (Broussonetia papyrifera) tree that is pounded thin and glued together with vegetable starch, usually from kumala (sweet potato) or manioke (cassava), then painted with traditional designs. Just as each work of tapa cloth is different and reflects talents of the artist, female Blue Moon butterflies seem to flaunt their own unique styles. • Photo courtesy of the Virtual Collection of Asian Masterpieces

Female Blue Moon

Another beautiful female Blue Moon butterfly with its own distinct pattern. For many months after moving to Tonga, we thought that we were seeing a multitude of different butterfly species nectaring on the flowers in our yard until I reared these and saw for myself that they are all female morphs of the same species.

Female Blue Moon Butterfly

Here’s yet another gorgeous female Blue Moon butterfly ready to be released into the wild. Her colors resemble the tapa cloth on the left in the next photo.

Long Tapa Cloth

Two long tapa cloths of approximately 60 linear feet (18.28 meters), each with its own patterns and earth-tone colors, just like the different female Blue Moon butterflies. I took this photo this year near Vaini on the main Tongan island of Tongatapu. The owner had placed them in the sun for the day to air them out. He was rightfully proud of his ngatu collection. Tapa cloths hold great value in Tonga, both monetary and sentimental, and are used ceremonially on special occasions. They are also given at graduations, weddings and funerals; and passed down as family heirlooms from generation-to-generation. Read more about tapa cloth in Wikipedia.

Tapa Cloth Butterfly - Female Blue Moon

This is one of my husband’s favorite female Blue Moon patterns. You can really start to imagine nature painting her wings the way Tongan women paint tapa cloth.

The female Blue Moon butterfly hovers over a plant to check for ants which might eat her eggs. After selecting a plant which has no ants on it, she lays at least one but often two to five eggs on the undersides of the leaves.

For months, we could not figure out which of the many host plants, that Blue Moon butterflies are known to use, might be available in Tonga. Then one day, to my complete surprise, a female Blue Moon “saw me standing alone” and landed right at my feet. She deposited eggs on a nearby plant, which we later discovered was Nodeweed. Mystery solved!

Nodeweed

Nodeweed (Synedrella nodiflora) is one of several host plants for the Blue Moon butterfly’s caterpillars. It grows wild in Tonga and can easily be found along unmowed roadsides and vacant lots.

Blue Moon Eggs

Two well-camouflaged green Blue Moon butterfly eggs hidden on the leaf’s underside.

Blue Moon Caterpillar

Blue Moon caterpillars are black and covered with prickly orange spines that deter predators (and handling by humans).

Blue Moon Pupa

Blue Moon chrysalises are brown with spines and well camouflaged. Adult Blue Moon butterflies eclose (emerge) about ten days after pupating.

Blue Moon butterflies are found from Madagascar, off the southeast coast of Africa, through South and Southeast Asia, to South Pacific islands (including French Polynesia, Tonga, Tuvalu, Samoa, and Vanuatu), and in parts of Australia, Japan, and New Zealand.

If you live in or happen to visit their range, keep an eye out for the snazzily-dressed males in their velvety black tuxedos with iridescent purple cummerbunds and the females styling their myriad elegant tapa-cloth formals. Two ladies never want to wear the same dress to the ball.

“Blue moon,
Now I’m no longer alone
Without a dream in my heart
Without a love of my own.”
–Frank Sinatra, Chorus

Meadow Argus Butterfly of Tonga

The Meadow Argus (Junonia villida) is a butterfly found in the Kingdom of Tonga in the South Pacific. I reared this one from the caterpillar stage. The butterfly is resting on my arm after being released. A few moments later, it flew up and away.

If it looks familiar to residents of North America, there’s good reason. It’s related to the Buckeye (Junonia coenia). One of the host plants for Meadow Argus is Porterweed (Stachytarpheta jamaicensis), a wonderful nectar plant that grows along roadsides and in empty fields on the island of Tongatapu, the main island of Tonga.

“I have been transformed.”

El Salvador is still recuperating from a devastating civil war that wracked the country from 1980 to 1992, leaving at least 75,000 people dead and tens of thousands more displaced. My site, Segundo Montes, is a community made up of five towns in the eastern department of Morazán, formed in 1990 by repatriated refugees who fled the country’s civil war.

Teaching about Host Plants

Suzanne Tilton demonstrates the importance of butterfly host plants in the Mariposario Turístico Almirante de Morazán, a large butterfly enclosure in El Salvador.

After nearly a decade in refugee camps in Honduras, residents returned en masse 25 years ago to reclaim their livelihoods and dignity. I wanted to help this once-war-torn community’s iconography transform itself from memories of combat fatigues to fluttery symbols of peace and hope.

When I arrived at the Mariposario Turístico Almirante de Morazán, I was thrilled to see the abundance and variety of butterflies – from Blue Morphos (Morpho peleides) to Zebra Longwings (Heliconius charithonia) and everything in between – flying in the gardens outside. It was a delightful sight and I knew immediately that I had arrived where I belonged.

The butterfly exhibit was built in 2008 as an agricultural project to raise butterflies but, within two years, it was abandoned due to lack of knowledge and support on how to raise and manage the rearing of butterflies. My job as an Educational Butterfly Farm Management Specialist was to train butterfly wranglers how to cultivate butterflies and maintain a healthy habitat for them inside the exhibit.

Dressing up as a butterfly

A delightful child visiting the butterfly zoo has dressed up as a butterfly.

I also visited several primary and secondary schools to teach the life cycle of butterflies and why they’re important for the mountainous environment. Children had the chance to hold and observe up close live specimens in the forms of eggs, caterpillars, chrysalises and adult butterflies. I used props to dress up the children as caterpillars, butterflies and moths. They cheered in delight when we released butterflies at the end of the presentation and watched them fly freely into the sky.

I knew I was having an impact when parents would stop me in the community and share that they had learned all about butterfly metamorphosis from their children.

One of the highlights of my experience in El Salvador was a weekend visit by 50 students from the University of San Carlos in Guatemala City, who came across the border to learn butterfly biology and butterfly zoo management with an emphasis on environmentally friendly sustainability.

There is a concerted effort to develop tourism along the Ruta de Paz (Peace Highway) from Morazán’s capital of San Francisco Gotera to El Salvador’s border with Honduras, along Highway 7. The butterfly zoo is strategically located along this route and is well positioned to attract the attention of vacationers headed to the cool air and brilliant sunshine of Perquín, eight miles farther north.

Teaching about butterflies

At 4,000 feet in elevation, Perquín is a popular destination of Salvadorans fleeing the heat and humidity of the coast and tropical lowlands. As time goes by, it is hoped that the Mariposario Turístico Almirante de Morazán will play its part in entertaining and educating tourists on the beauty of butterflies while it continues to contribute to the economic well-being of the community.

A visitor to the butterfly zoo experiences the joy of holding a Tiger Longwing (Heliconius hecale).

In conjunction with the nascent tourism industry, I was privileged to make presentations and conduct field trips for university students studying tourism and hospitality at the nearby Technical Institute of Father Segundo Montes.

I experienced such a feeling of joy and satisfaction as I watched mesmerized visitors hold a butterfly for the first time.

Just as a caterpillar transforms into a butterfly, I have been transformed into a different person by serving as a Peace Corps Response volunteer.

Suzanne Tilton retired from teaching, mostly primary grades, after 28 years of service in 2010. She has raised butterflies for over 20 years and has shared the wonder of butterfly biology with thousands of children and adults. Suzanne and her recently retired husband, David, were so impressed with Peace Corps in El Salvador that they have applied for and been invited to teach English in the South Pacific Kingdom of Tonga for 27 months starting in August 2015.

Editor’s Note: This post was written and originally published in Peace Corps Passport, the U.S. Peace Corps’ official blog, on 22 April 2015 to commemorate Earth Day. Suzanne and her husband, David, eventually chose not to serve in Peace Corps, but did move to Tonga in October 2015, from where they continue to research, publish and teach worldwide about the wonder and joy of butterflies.
