Did you know there are about 17,500 species of butterfly in the world? We take flight into the world of butterflies with three podcast episodes dedicated to these brightly coloured winged creatures.

Butterflies Are Secret Monsters – Science Vs

Butterflies sip turtle tears – add that to your list of fun facts for the next dinner party. It’s true. If you look it up, you will find delightful images (if not disturbing, and a reminder that nature is always surprising us in ways we did not expect.)

This is the topic of a phone call between host Wendy Zukerman and biologist Chandreyee Mitra, which begins the podcast episode with: “You usually see them sort of mobbing the turtle’s head, and it’s like, poor turtle!” This is not the rise of the butterflies against their turtle overlords; there must be a reason they are drinking tears, right?

Mitra and her team asked the same question, and it turns out that butterflies are after the salt in the tears, because they need it to help their nerves and muscles work, Zukerman explains.

The conversation takes another unexpected turn, because researchers then noticed that male butterflies were consuming more salt. “When you take a close look at who shows up around the watering hole, it’s kind of a sausage fest. It’s mostly the blokes… and Chandreyee wondered: Why? Like, why are the males mostly scrounging around for salt?” reflects Zukerman.

Mitra wanted answers, and began studying the effects of butterflies and salt. “For a while my Twitter handle was ‘Butterfly Voyeur’,” she laughs. “What we found was that males who’ve had salt actually mate more frequently than males who were given water.”

“How lucky they got”, Zukerman interjects.

“Yes, exactly,” Mitra says.

And in the species Mitra was studying, Pipevine Swallowtails, she noticed that the males seemed to “show off” that they had salt.

“The courtship is really beautiful, the male making these vertical swoops around the female,” she says.

With Mitra’s enthusiastic descriptions of this “absolutely gorgeous blue and black butterfly with these beautiful tails” that “flash these crazy bright colours” when they move in the sun, it’s hard not to be drawn into this episode like a moth to a flame, or rather, like a butterfly to a turtle.


The People’s Insect – Sidedoor

“I wanted to know, what’s it like to be a butterfly?” host Lizzie Peabody tells us. “But instead of a story of pretty little things floating from flower to flower, [ecologist Dara Satterfield] told me an adventure tale of survival, instinct and a migration that spans generations. The story doesn’t end when a caterpillar becomes a butterfly. Friends, that is just the beginning!”

Peabody’s description of these insects is magical: “Their wings have these bright-orange windows surrounded by black panes, ringed with little white dots, tiny stained-glass masterpieces.” It’s no wonder then that these butterflies captured Satterfield’s attention – she thinks of monarch butterflies as “the people’s bug”. Why? “We connect with them,” she says. “We connect with them in a way that we don’t with most insects, and I think that’s partly because of their migration story.”

Every year, monarchs travel more than 4,000km from the northeastern US and Canada to reach overwintering grounds in southwestern Mexico. “These half-gram heroes [are] on a dangerous mission,” Peabody says. (And yes, they really are that small, Satterfield tells us later, explaining that these butterflies have a wingspan of about four inches (10cm) and weigh about as much as a raisin.)

“We know that they go to the same 12 or so mountain tops every year, that their great-grandparents or maybe even great-great-grandparents had been to the year before. They’ve never been to these sites themselves. Somehow, they find them year after year,” Satterfield says.

She goes on to describe the life cycle of monarch butterflies – egg, caterpillar, butterfly, egg, caterpillar, butterfly – one life cycle is only around six weeks. As they mature on milkweed plants, they are slowly but surely pushing across the country towards Mexico.

That innate instinct is so strong, Satterfield says, that “even if you put them in a cage to study them, they will sometimes sit in the south or southwest corner of the cage. That’s how sort of driven they are to go that direction.”

Biologist Karen Oberhauser chips in here, explaining that as the monarch butterflies soar above the clouds on their journey, they are using an internal biological clock to keep track of time and know where to fly. “If they’re trying to fly south, and it’s morning, they should keep the sun on their left. And if they’re trying to fly south and it’s afternoon, they should keep the sun on their right,” she explains.

And eventually, thousands of kilometres and generations later, they make it to Mexico.

“It is an incredible sensory experience,” Oberhauser says. You are drawn in, transported in the audio to a cold, misty mountain top. You can hear the jungle, and you can almost hear the beat of butterfly wings.

“We started seeing a few butterflies and they’re just a few flying around,” Oberhauser remembers. Then there’s around 30. Then 50. Then, suddenly, a cloud of orange and black,” Peabody describes.

“It’s overwhelming… it’s such a three-dimensional experience that the butterflies are just flying everywhere around you. They’re flying as high up as you can see in the sky and right down to the ground, and they’re covering the trees,” Oberhauser says.

“They have so many butterflies on them that it weighs down the branches,” Satterfield adds. Eventually, they’ll start their journey back home. But next year, it’ll start all over again.

Lessons from Monarch Butterfly Migration The Morgan Harper Nichols Show

  • Format: Single episode
  • Year: 2021
  • Listen on: Apple Podcasts, Spotify or wherever you find your podcasts.

Changing pace from the scientific to the whimsical, let Morgan Harper Nichols’s soothing and enchanting voice take you on a journey of butterfly migration. “I think about the journeys I’ve taken in my own life and how I look forward to arriving at the destination,” Nichols says. “The idea of travelling all of these miles, through multiple landscapes, terrains and weather conditions should result in finally arriving at a destination, right?”

But Nichols poses that there is a different lesson learnt from monarch butterflies, a “reminder of what it means to pave the way. To carry on, on a journey that you might not actually live to see the end of.”

In this four-minute podcast episode, Nichols reflects on human generational histories, likening our own journeys to butterflies who only live a few a weeks but are as intrinsically a part of the migration even though they may not start or finish it – this interconnectedness that ties monarchs together is within our humanity, too.

Further, Nichols ponders what this means for us as humans. We are all drawn to the destination, the win, the prize, but butterflies remind us that this is not the end goal. “What greater journey are we willing to be a part of, even if it’s only for a limited time? Even if it’s someone else who lives to see the finish line?” Nichols asks. Here, whether purposely or not, there is a feeling of the butterfly effect (no pun intended), one action affects another, and so forth. Are you willing to be a part of the greater journey, even if you don’t get to see the end of it?

Nichols ends this reflection with a poem – a reminder to be more like monarch butterflies – a portion quoted here:

Oh how beautifully

your presence matters here

(even without knowing

what your impact will be

through the years). DM/ML

    Even these short excerpts are amazing and lyrical ! Thanks.

  • Jane Crankshaw says:

    A marvelous little read – I’m now yearning for more! Between butterflies and bees, who needs more to inspire us ridiculous humans!

  • Antonette Rowland says:

    I was wanting to reflect on the death of my husband 21 years ago on 22nd June, one year and a day after my mother on 21st June. . I can see how they were part of the journey in their own time and own way but so am I only a part. Our children and grandchildren will live on and who, if anyone will eventually cross the finish line. Our job is to carry on our part as best we can for the sake of others continuing after us. Thank you.

    Yes, I know tortoises are part of the genus turtle but as *not Americans* by convention we reserve the word ‘turtle’ for the water animals and ‘tortoise’ for the land one.
