Butterfly Lady

The Blue Morpho butterfly is probably one of the best known and most popular worldwide. It is particularly known for its luminescent blue wings. The brilliant blue coloring is a result of the microscopic scales on the backs of their wings, which reflect light.

The Morpho is a highly diversified species with more than twenty subspecies. It is found from Mexico and throughout Central and South America and is endemic to Trinidad and Tobago. Located primarily in rainforests, however, the species can be found in habitats ranging from mountains, ravines, cleared lands, and streams.

Many butterfly houses have these magnificent butterflies on display. The first encounter with a Blue Morpho was at Butterfly World in Coconut Creek, Florida. I was enchanted with their brilliant blue color and mesmerized as I watched them fly gracefully throughout the exhibit. I immediately fell in love!

The undersides of the blue morpho’s wings are dull brown, with eyespots (ocelli) and other gray, black, and red markings. The larger eyespots may help deter predators, who at first glance could think the eyes belong to a larger creature.

As much as I love watching these wonderful butterflies in captivity, it does not compare to seeing them in the wild. A few years ago during a trip to Costa Rica, I was walking down a road when a flicker of blue glided past me. I started to run to keep up with the butterfly. The erratic flight pattern makes it quite difficult to follow. This is on purpose because this is how they defend themselves against predators. The Blue Morpho has what is known as a “flashing” defense. When in flight, its wings appear to flash from vivid blue to dull brown. The butterfly seems to continuously disappear and reappear again, making it very hard to track through the jungle.

The Morpho butterfly does not feed on the nectar from flowers but rather feeds on the juices of fermenting fruit. I was able to lure butterflies to the garden by setting out fruit in a bird bath.

Blue Morpho butterflies are farmed raised and then the live pupae are shipped all over the world for butterfly exhibits. Many people raise these butterflies in captivity to be used for collectors in display cases. Their wings are also used to make jewelry. This can be disturbing for many people but I would like to point out that the butterflies you see in boxes or in jewelry were not snatched from the wild population, but raised on a butterfly farm for the specific purpose of being sold as what is known as “dry stock”.

If you want to see these brilliant blue beauties you can travel to Costa Rica or your nearest tropical butterfly exhibit. You can click here to see a list of tropical butterfly houses in the United States and Canada.

“Do you have a favorite butterfly?” I often get asked this question. I love all butterflies but I have to say that the Zebra Longwing (Heliconius charithonia), has always been my favorite. These graceful butterflies hold a special place in my heart because they have unique behaviors that distinguish them from other butterflies.

Most butterflies and moths rely on sugar-laden nectar or fruit to provide the energy they need. Zebra Longwings not only sip nectar from flowers but they feast on pollen. Pollen contains much more protein than can be found in normal butterfly diets. The extra nutrients allow these Zebra Longwings to lay more eggs and to live as long as six months as adults, rather than the few weeks most butterfly species live.

Another unique characteristic of these butterflies is that they roost in large groups at night. These communal colonies can range from a few individuals to 30 butterflies or more. Roosting together provides protection from predators and retains warmth. The butterflies return to the exact same spot to settle down every night. Groups have a social hierarchy that allows the oldest butterflies to pick the best sleeping spots before the others bed down around them. The older butterflies of the group also give the younger ones a nudge to get going in the mornings.

Apparently, these delicate butterflies memorize locations of their preferred flowers on which they feed and plan the most efficient route by which to visit their nectar and pollen sources. I observed this behavior one summer in my Florida garden. I planted various flowers in containers along the wooden pool deck in the backyard. The butterflies’ roost was located in an oak tree about 75 feet away. Each morning, around 10:00, they would leave the roost and fly toward my garden. They began feeding on Mexican sunflowers planted along the south side of the deck and then moved north visiting each container of flowers in the order they were placed on the deck. They ended up feeding on the zinnias, which were planted in rows, traveling down the row of flowers. From there they flew out into the fields nearby where Maypop (Passiflora incarnata) and Corkystem Passionflower (Passiflora suberosa) grew wild.

Female Zebra Longwings lay their eggs on Passion Vines (Passiflora spp.), but their favorite seems to be Corkystem Passionflower and Maypop (Passiflora incarnata). The females deposit their eggs on the tendrils and the tip of the leaves, usually in clusters. In the first few days, the caterpillars are gregarious, but they quickly break out to feed on their own. Passion vines contain toxic compounds that are ingested by the caterpillars making the caterpillars, as well as the adult butterflies, a poisonous meal for predators. The white or yellow stripes and spots on the adults’ wings and body serve as a warning signal to potential predators of the butterflys’ unpalatable and poisonous nature. These bright, contrasting warning colors are known as aposematic coloration.

A few hours before eclosion (emergence from chrysalis), females release a pheromone that attracts males. As a female gets ready to emerge from her chrysalis, males will begin to swarm around her, jostling and flapping wings to push each other aside. The winner of this scuffle mates with the female before allowing her time to expand and dry her wings. The male passes a nutrient-rich spermatophore to the female which reduces her attractiveness to future mates. Apparently, this mating behavior, referred to as ‘pupal rape‘, is beneficial to the survival of the species by allowing the female to go straight to laying eggs, not having to exhaust energy in ritualistic mating practices.

I find Zebra Longwings so fascinating. I feel so blessed when these beautiful, striped butterflies grace my garden!

A few years ago, I was at a farmers’ market in Cary, North Carolina, where I had a display of live Monarch (Danaus plexippus) butterflies. Monarch chrysalises inside clear containers were available so that people could observe the pupa up close. One woman was quite intrigued by the beauty of the chrysalis. After looking at the chrysalis for a long time, she asked me, “How did you manage to paint those little gold dots on there?”

I suppose, if you look closely, the gold dots on a Monarch chrysalis do look like gold paint. It seems incredible that nature would adorn a living creature with a golden crown. Rick Mikula in The Family Butterfly Book, surmises that the early colonists of North America thought that the gold rim around the Monarch chrysalis reminded them of the king’s crown, so they named the butterfly “Monarch.”

A group of researchers in Germany did a careful study of the properties of these spots. They are not metallic (so they aren’t really gold), but the cells reflect light like metals do, giving them the appearance of being metallic. The gold is created by a combination of a carotenoid pigment and a hill-like structure that reflects light from the peaks to create the golden sparkle.

The scientists come to a few conclusions about the purposes of the metallic specks:
• Camouflage by reflecting colors of the surroundings and breaking up the shape of the pupa; they might also look like dew droplets.
• Warning coloration to predators that the pupa is toxic.
• Filtering particular wavelengths of light which might be harmful to the Monarchs.

Richard Stringer, in 2012, pioneered the use of various types of X-rays, MRIs and X-ray microtomography to peer inside a Monarch chrysalis and record the dramatic changes inside the chrysalis as it develops. His observations revealed that the gold spots on the outside of a chrysalis are ports of entry for oxygen.

Interestingly, before those collecting and studying butterflies and moths became known as “lepidopterists,” they were known as “Aurelian”. Aurelian comes from the Latin word for gold, which referred to the early collectors’ searches for golden chrysalises. The word “chrysalis” itself originates from the Greek word “chryso,” which also means gold.

Gold is a precious metal associated with wealth, grandeur, and prosperity, as well as sparkle, glitz, and glamour. Monarch butterflies truly are precious, natural living creatures that symbolize all of the above.

The perfect time to sow native milkweed as well as other native perennials outdoors is right when Mother Nature does it, in the fall! Exposure to cold temperatures and moist conditions during winter will stimulate germination. Spring planting is also possible but artificial stratification of the seed is recommended to enhance germination. (Click here to read how to plant milkweed in the spring.)

Choose Your Site and Best Planting Time

Full sun is best, and a “border area” between lawn and woods or a more natural area is perfect. Planting should be done AFTER a killing frost in your area, or after you’re quite sure the growing season has ended, and your seed won’t sprout until spring. In heavy winter areas, that means from late September or October up until the ground freezes. (Many gardeners combine wildflower seed planting with fall bulb planting, and that’s always a good idea. The times for both are identical.) If you don’t have much frost in your area, you should plant just before your rainiest season begins. South Florida plants annuals in the fall for winter bloom. Coastal areas on the Pacific can plant anytime during the late fall or winter. Native milkweeds need full sun to grow so make sure the area you choose has at least least 6-8 hours of sun per day.

Prepare the Soil

The general routine when sowing seeds in the fall is to clear out a garden bed of weeds and debris.  Sometimes it is an area of a garden bed that already has other plants in it. After you clear the planting area of weeds, loosen the soil a couple of inches with a small shovel, hoe dag, or another tool. You can spread an inch or two of good compost on top.

Sow the Seeds

Space the seeds out according to the directions on the seed packet. If you have a large area and a quantity of seeds you can simply throw them out by the handful. If you do scatter them loosely by hand, come spring when the seeds start to germinate you may want to thin them out if they are extremely close together.

Simply press them against the soil with your hand or the sole of your shoe. If you’re seeding a large area you could also use a seed roller. American Meadows says if you’re planting in spring or fall, there is generally no need to cover the seed. Unlike veggie seeds, which are typically planted in holes and buried within the soil, wildflower seeds are scattered on top of the soil and left exposed.

Water

Once you’ve pressed the seeds into the soil, give the area a good watering to set the seeds. Because you’re planting in the fall, you won’t need to water after this until early spring when the seeds start to germinate.

Walk Away

Now walk away and forget about them and let Mother Nature do her magic. As winter progresses, they’ll naturally be exposed to the eight to ten weeks of cold temperatures required for them to germinate when spring arrives.

 

 

 

 

One of the surest ways to see fall-migrating Monarch butterflies is to plant flowers that attract them. Monarchs will drop from the sky for the nectar they need for energy during fall migrations.

Monarchs will search for nectar plants the entire time they are traveling to their winter roosting sites in Mexico. Gardens can provide a place for the migrating Monarchs so they can refuel and continue their journey. Help Monarchs by planting flowers that bloom late into the fall such as the flowers listed below.

Asters (Aster spp.) are a favorite of Monarchs in the fall, particularly the New England Aster (Symphyotrichum novae-angliae). Other asters include Smooth Aster (Symphyotrichum laeve), Aromatic Aster (S. oblongifolium),  and Calico Aster (S. lateriflorum).

Sunflowers (Helianthus spp.), including Mexican Sunflower (Tithonia rotundifolia) and Swamp Sunflowers (Helianthus angustifolius) are late bloomers and provide wonderful nutrition for migrating Monarchs.

Many Lantanas are still blooming. I had several Monarchs stop in late October in my North Carolina, USA, garden to sip the nectar from ‘Miss Huff’ Lantana (Lantana camara ‘Miss Huff’).

Goldenrod (Solidago spp.) is a wonderful fall blooming perennial and is one of the major nectar sources for the Monarchs’ trip back to Mexico.

The brilliant purple-crimson bloom of Ironweed (Vernonia fasciculata) is very attractive to Monarchs.

Other great nectar flowers to plant for fall-migrating Monarchs include
Purple Coneflowers (Echinacea purpurea).

Autumn Joy Stonecrop (Sedum ‘Herbstfreude’) burst into bloom in fall. If left standing, they provide winter interest and food for birds.

Liatris spicata, commonly called Blazing Star or Gay Feather is a native perennial that makes a wonderful pitstop for migrating Monarchs.

Anise Hyssop (Agastache foeniculum), also known as Giant Hyssop and Lavender Hyssop is a native perennial.

The Monarchs flock to the Joe Pye Weed (Eupatorium purpureum).

The red blooms of  Cardinal Flower (Lobelia cardinalis) not only attract migrating Monarchs but also migrating hummingbirds.
