Ever seen a back-lit monarch butterfly?
It's like a stained-glass window in a centuries-old steepled church where you cannot see the ugliness of the world, but its beauty.
Monarchs are like that. Those iconic butterflies excite, inspire and transform you, just like stained glass windows.
We captured these images at dusk of a monarch fluttering around an aphid-infested milkweed, a tropical milkweed, Asclepias curassavica, on Aug. 7 in Vacaville, Calif.
The orange butterfly was nothing but a blur until we stopped the action (1/4000 of a second) with a 200mm macro lens mounted on a Nikon D500.
The beauty (the monarch) eclipsed the beast (oleander aphids) in a moment of time.
Unless it encounters a predator or parasitoid or another life-threatening factor, the egg will usually hatch 3 to 4 days after Mama Monarch deposits it beneath a milkweed leaf. As you know, monarchs lay their eggs only on milkweed, their host plant.
If you enjoy macro photography, it's a delight to photograph an egg with a highly specialized lens like the Canon MPE-65mm lens. Or you can observe the tiny egg with a magnifying glass or microscope.
How do you rear it?
Naturalist Greg Kareofelas, an associate of the Bohart Museum of Entomology at the University of California, does it this way:
"I put a single egg on its leaf in a small salsa container (the little plastic ones you would get at a Mexican restaurant). I take a square of toilet paper and fold it into a small square (3/4 of inch), dampen it and squeeze it so it is not sopping wet, just damp, and set the leaf and egg on the top. Put the lid tightly on the container. This keeps a level of moisture in the container. I check the containers daily, changing the toilet paper square to keep from molding."
"I raise the larva in that container until it gets big enough to move to a larger container. As long as you pay attention and check them often to make sure there is no mold or such, I have raised many this way successfully. The tight lid and slight moisture keeps the food plant fresher."
"You don't want loose water in the container, just enough so it is not dry," he says.
Among the many species of butterflies he's reared: the dogface butterfly or California state insect, Zerene eurydice; the Colias behrii, the Behr's sulphur or Sierra green sulfur; and the monarch, Danaus plexippus.
When our family rears monarchs, we usually begin with the caterpillars instead of the eggs. They're easier to find and collect. However, if you see a monarch laying her eggs, you know exactly where to look! Last weekend we watched a monarch deposit her eggs on our tropical milkweed, Asclepias curassavica, and our narrow-leaf milkweed, Asclepias fascicularis. We collected three eggs from the fascicularis and let the others be.
An adult monarch can lay about 400 eggs in her lifetime, Kareofelas says. Only a few survive due to predators and parasitoids and other factors. The major parasitoid in our garden is the tachinid fly which lays its eggs in or on the host or deposits its eggs on the milkweed leaves.
"If you start with the egg, the chance of it being parasitized is really small," says Kareofelas, who has been rearing butterflies most of his life, and especially for the last 15 years.
When the egg hatches into a larva or caterpillar, the 'cat will eat the eggshell first and then go about munching the milkweed. When it gets bigger, it's time to move it into a larger container. You must keep the milkweed fresh, as it can dry out quickly. Kareofelas likes to use water-filled floral tubes and dampened packing foam to keep the leaves/stems moist.
Our family's procedure to rear caterpillars: fill a heavy, wide-bottomed, narrow-necked tequila bottle with water, add sprigs of milkweed and the 'cats, and place in a zippered, net butterfly habitat. We place ours in our kitchen, a tachnid-free environment! Those tachnids can be sneaky! Also, replenish your milkweed and water daily, and remove the frass (excreta) daily.
It's a joy watching the complete metamorphosis, about a 30-day development from egg to larva to chrysalis to adult. The larval stage or caterpillar stage usually lasts 10 to 14 days, during which time the caterpillar will go through five instars (when it molts or sheds it skin). The 'cat will then form a "j" and pupate. The chrysalis stage lasts about 10 to 14 days, and voila! The familiar monarch icon ecloses and it's released back into the garden to start the cycle all over again.
Yes, it's a joy to watch them. But it's not a joy watching a tachnid-infested monarch caterpillar or a chrysalis. (We'd rather the tachnids lay their eggs in such pests as cabbage loopers or tomato hornworms.)
A good place to see butterfly specimens from all over the world is the Bohart Museum of Entomology (now temporarily closed due to the COVID-19 pandemic. Of the nearly eight million specimens in the Bohart, some 500,000 are in the Lepidoptera collection, curated by entomologist Jeff Smith. He and Kareofelas display and discuss the Lepidopterans during the open houses. In the meantime, watch the moth-butterfly videos on the Bohart Museum page.)
We call it the Fourth of July or Independence Day.
Our 13 American colonies rose up against the monarch of Great Britain, King George III, and declared themselves free and independent.
This weekend, no thanks to the coronavirus pandemic, we won't celebrate with fireworks, parades, picnics, family reunions or baseball games, but we will give thanks to the 13 colonies who gave us our freedom from a troubling monarch.
Today we watched a different kind of monarch, a monarch butterfly, Danaus plexippus, gain her freedom as she eclossed from her chrysalis.
From an egg to a caterpillar to a chrysalis to an adult..."Welcome to the world, Ms. Monarch."
But first, let Ms. Monarch cling to the Hot Lips salvia, Salvia microphylla, and dry those wings. Let her watch the honey bees, carpenter bees, cabbage white butterflies, Gulf Fritillaries, damselflies, and syrphid flies forage. Let her react when they buzz, bounce or bump into her. Beware of that praying mantis!
She will know when she's had enough...just like the 13 colonies knew when enough was enough and King George III lost his American colonies.
The monarch caterpillar feasting on the tropical milkweed, Asclepias curassavica, in Vacaville, Calif., kept doing what monarch 'cats do best--eat.
She insisted on devouring the leaves as if there were no tomorrow--and today would end soon.
How did we know her gender? Our Danaus plexippus pupated, formed a chrysalis, and emerged. Oh, you beautiful gal!
Folks who comment that someone is "eating like a pig" or "eating like a horse" or "wolfing it down," have probably never seen a monarch caterpillar chow down, scarf it up or shovel it in.
One minute our little 'cat is stretched out on a leaf, binge eating. The next minute the leaf is gone and she's porking out on a second leaf. And scouting for a third.
Eric Carle titled his classic children's book, "The Very Hungry Caterpillar," quite well. His little 'cat ate everything in sight: gobbling, guzzling, gorging and gulping down everything from fruits and vegetables to junk food.
Remember the story? First, the little 'cat ate an apple, two pears, three plums, four strawberries, and five oranges but was still hungry. Famished, really. So he ate a piece of chocolate cake, a lollipop, a piece of cherry pie and a cupcake...and more...and he wasn't little anymore.
Many folks sheltering at home during the COVID-19 crisis can certainly identify with the snatch-and-grab menu of "The Very Hungry Caterpillar."
Did someone say "chocolate cake?"
(Editor's Note: Those planting the tropical milkweed in temperate zones (like here in Vacaville,Calif.) must remove or cut back the tropical milkweed by winter. "A protozoan parasite of monarch butterflies, Ophryocystis elektroscirrha or OE for short, can travel with monarchs visiting the plants and become deposited on leaves," explains the Xerces Society for Invertebrate Conservation.)
Welcome, Danaus plexippus!
A monarch butterfly, the first of the year, fluttered through our family pollinator garden in Vacaville, Calif. last Sunday and hung around for about two hours. We clocked him in at 5 p.m. and he exited around 7. He was on the move!
"Boy Butterfly" visited:
- the tower of jewels (Echium wildpretii)
- a yellow rose ("Sparkle and Shine," related to the Julia Child rose, a purchase from the California Center for Urban Horticulture, UC Davis, during its 2013 Rose Day
- a honeysuckle (genus Lonicera)
- a tropical milkweed (Asclepias curassavica) (it ignored the native "showy milkweed," Asclepias speciosa
- a butterfly bush (Buddleia davidii)
- a mallow (Althaea officinalis)
- a blooming succulent, hens-and-chicks (genus Echeveria): when it's blooming, it's referred to as a "rooster"
Then Boy Butterfly touched down on the ear of a cat (garden sculpture) while a mama California scrub jay watched closely. We could hear the baby birds chirping "We're hungry! We're hungry! Let's eat!"
Fortunately for the monarch, Mama's menu changed. She settled on some honey bees nectaring on the catmint (genus Nepeta), and left my Boy Butterfly alone.
A male European wool carder bee (Anthidium manicatum) chased him. A Gulf Fritillary followed him. And a bumble bee (Bombus vosnesenskii) almost collided with him.
And then this persistent photographer, armed with a 200mm macro lens, stealthily approached him...
