Everyone remembers the holes.
Those tiny, circular cutouts in the thick cardboard pages of The Very Hungry Caterpillar are basically a rite of passage for every toddler born since 1969. You stick your finger through the apple, then the two pears, then the three plums. It's tactile. It’s simple. Honestly, it’s kind of a masterpiece of engineering disguised as a bedtime story. Eric Carle didn’t just write a book about an insect with an eating disorder; he created a sensory experience that has somehow managed to outsell almost every other children's book in history.
We’re talking about a book that sells roughly one copy every thirty seconds. That is wild.
But why? If you look at it objectively, it’s a story about a bug that eats a bunch of junk food, gets a stomach ache, and then goes through a biological metamorphosis. It shouldn't be this world-shaking phenomenon, yet here we are, decades later, and it’s still the top of every baby shower registry.
The Weird Origin Story of a Hole Puncher
Eric Carle didn't start with a caterpillar. He started with a hole puncher.
He was actually a graphic designer and illustrator who had spent years in advertising. One day, while messing around with a stack of paper and a hole punch, he thought about a bookworm. He called the original idea A Week with Willi the Worm. He liked the idea of a character literally eating its way through the physical pages of the book.
His editor, Ann Beneduce, wasn’t sold on the worm. She thought a worm was a bit... unappealing? Slimy? She suggested a caterpillar instead. Carle famously replied, "Butterfly!" and the rest of the narrative fell into place. That one pivot changed the trajectory of children's literature.

The production was actually a nightmare at first. In the late 1960s, American printers couldn't figure out how to do the die-cut pages and the varying page widths without it being prohibitively expensive. They ended up having to find a printer in Japan who could handle the specific requirements of the different-sized sheets and those iconic holes. It was a massive gamble for a simple story about a larva.
It’s Not Just About Bugs
Parents love this book because it’s a multi-tool for development.
Think about it. In about 200 words, you’ve got the days of the week. You’ve got counting from one to five. You’ve got the life cycle of a lepidoptera. You’ve even got a subtle lesson on nutrition—though the caterpillar’s "binge" on Saturday is basically a fever dream of 1960s picnic food. Salami? Swiss cheese? A lollipop? It’s a chaotic menu.
But the real magic is the art style. Carle used a collage technique that involves hand-painted tissue paper. He would stain thin sheets of paper with acrylics, using sponges, brushes, and even carpet scraps to get those textures. Then he’d cut them out and layer them. This is why the colors look so deep and vibrating. It doesn't look like a "clean" digital drawing. It looks like something a kid could almost do, but elevated to high art.
The Saturday Binge and the Stomach Ache
Let’s talk about that Saturday feast. This is the part where kids usually lose their minds.
- One piece of chocolate cake
- One ice cream cone
- One pickle
- One slice of Swiss cheese
- One slice of salami
- One lollipop
- One piece of cherry pie
- One sausage
- One cupcake
- One slice of watermelon
That night, he had a stomach ache. No kidding.

There is something deeply relatable about the caterpillar's ambition. He’s small, he’s hungry, and the world is full of colorful, delicious things. But the "green leaf" on Sunday is the reset. It’s the moment of self-regulation. Most experts in early childhood education point to this specific sequence as a way children learn about consequences and the feeling of "enough."
Interestingly, some critics over the years have tried to read way too much into this. Is it a critique of consumerism? An allegory for the American Dream? Honestly? Probably not. Carle always maintained that it was a book of hope. You grow up, you unfold your wings, and you fly into the world. It’s a transition story.
Why the Colors Don't Fade
If you pick up a copy of The Very Hungry Caterpillar from the 70s and compare it to one bought yesterday, the vibrancy is still there. Carle was obsessed with color theory. He understood that children respond to high contrast.
The white background is crucial.
Many children's books of that era were cluttered. Carle left massive amounts of white space. This allows the focus to remain entirely on the object—the red of the apple, the green of the caterpillar’s body. It reduces cognitive load. For a two-year-old, this is the difference between a book they can "read" themselves and one that is just a blur of noise.
The Legacy of the Butterfly
Eric Carle passed away in 2021, but his museum in Amherst, Massachusetts—The Eric Carle Museum of Picture Book Art—remains a pilgrimage site for people who take this stuff seriously.

The book has been translated into over 60 languages. Whether you are reading it in Spanish (La Oruga Muy Hambrienta) or German (Die kleine Raupe Nimmersatt), the rhythm stays the same. The "pop" of the caterpillar emerging from the egg is universal.
One thing people get wrong: they think the caterpillar "builds a cocoon."
Actually, in the book, Carle uses the word "cocoon," but most butterflies actually form a chrysalis. Carle knew this. He was a nature lover. But he used "cocoon" because that’s what his father told him when he was a boy, and he felt the word had a more poetic, "woolly" feeling for children. He prioritized the emotional resonance of the word over the strict scientific terminology, which is a very "human" way to write.
What You Should Do With This Information
If you’re looking to build a library for a child, or even if you're just a fan of design, don't just buy the standard board book.
Look for the "Big Board Book" editions if you have a toddler who likes to chew on things; they are indestructible. If you are an educator, use the book as a jumping-off point for "tissue paper collage" art projects. It’s the easiest way to teach kids about layering colors.
More importantly, use the book's structure to talk about time. The progression from Monday to Sunday is one of the most effective ways to teach the concept of a "week" to a preschooler.
Next Steps for Parents and Educators:
- Audit your version: Check if you have the 50th-anniversary edition, which often includes a guide on Carle's specific "tissue paper" technique.
- Interactive Reading: Instead of just reading the words, let the child "feed" the caterpillar by poking fingers through the holes. It builds fine motor skills.
- The "Sunday Leaf" Lesson: Use the transition from the junk food Saturday to the green leaf Sunday to discuss how different foods make our bodies feel.
- Create Your Own: Get some tissue paper, some watered-down glue, and some acrylics. Let a kid make their own "hungry" animal. It teaches them that art isn't about being perfect; it's about texture and shape.
Ultimately, the book works because it doesn't talk down to kids. It’s a sophisticated piece of art that happens to be about a bug. It’s a reminder that even the smallest, hungriest thing has the potential to turn into something beautiful if it just keeps eating and growing.
