Secret Pollinators

Can a wild bee really disappear for 144 years? A volunteer with a net just proved the answer is stranger than you'd think. We follow the rediscovery of a wool-carder bee last recorded in the 1800s, a sweat bee unseen since 1906, and a never-before-documented "charming mining bee" caught in the act with a load of pollen — all turned up by trained volunteers running the first statewide bee survey in...

Happy Pollinator Week! Tell someone you love native wild bees and they'll start talking about honey every time. But the honey bee is a European import — it's not even one of the four thousand native wild bee species that live in the United States. This is a short, joyful one: a celebration of the bees most people never notice, the ones in every parking lot and sidewalk crack, the ones already unde...

A quick bonus update: how a five-minute email led to an official Montana Pollinator Week proclamation — and how you can get the same thing done in your own state before Pollinator Week wraps up. www.secretpollinators.com Resources: State of Montana, Governor's Proclamation, Montana Pollinator Week, June 22–28, 2026 (signed by Gov. Greg Gianforte) #PollinatorWeek #NativeBees #MontanaPollinatorWeek...

It started with one woman's frustration and a unanimous city council vote in Asheville, North Carolina, in 2012. Fourteen years later, more than 400 American towns and college campuses have made formal commitments to become better habitat for native bees. This National Pollinator Week, we explore what the Bee City USA movement actually does, why the science of solitary bee foraging ranges makes ur...

A bumblebee leaves her nest with no map, no GPS, and no instructions. By the end of the week, she'll have figured out the most efficient route between every flower patch in her territory — reducing her total flight distance by eighty percent. That's not a metaphor. Researchers tracked it with radar. In this episode of Secret Pollinators, Kelly digs into the hidden navigation science of wild bees:...

A small seaside town north of Dublin set out to save a vanishing ginger-colored bumblebee — and the way they did it holds a lesson for every gardener, balcony grower, and small-space planter in America. This week we travel to Skerries, Ireland, to meet the large carder bee and the community that built it a home out of wild meadows. Then we come home to discover the "secret hum" of buzz pollination...

Go out to a meadow at dusk and look closely at the flowers — some of them are occupied. Wild bees sleep out in the open, and once you know to look, you'll never stop seeing them. In this episode, Kelly opens up the secret nighttime life of native bees: why the females go home to their burrows while the males sleep outside in the flowers, the astonishing way a sleeping bee holds on (with its jaws),...

For 40 million years, a small group of bees has been pulling off one of the most elegant heists in the insect world. They build no nests. They raise no workers. They never collect a single grain of pollen. Instead, they walk into the colonies of other bumblebee species and quietly take them over. They are the cuckoo bumblebees — and in this episode of Secret Pollinators , we meet all six species l...

The US olive oil market is worth nearly three billion dollars — and 95 percent of it is imported. But across seven American states, a small, quality-focused domestic industry is growing. And native bees, without invitation or management, are showing up in those groves every spring and doing something that a landmark 2013 study in Science confirmed: improving crop fruit set in ways that honey bees...

A brand-new study — published this week in the Journal of Animal Ecology — just revealed something remarkable about bumble bee colonies: they function as living thermostats, maintaining their brood at a precise 30 to 33 degrees Celsius, which is 86 to 91 degrees Fahrenheit, using only the bodies of their workers. When temperatures drop, bees vibrate their flight muscles to heat the nest. When it g...

Everybody knows grasses are wind-pollinated. Right? RIGHT?? Turns out the textbooks have been quietly leaving something out. Bees — honeybees, bumblebees, sweat bees, mining bees — are visiting grass flowers and combing pale yellow pollen straight off the anthers. And they're doing it without the usual floral road signs: no nectar, no big colorful petals, no UV bullseyes. So how on earth are they...

It's spring. Things are emerging. Something just buzzed past your ear, and your shoulders went up to your eyeballs. But was it a bee? A wasp? A fly? A genuinely surprising number of the "bees" in your garden are actually flies wearing a very convincing costume. In this episode, Kelly walks you through a five-second checklist — wings, antennae, eyes, waist, hair — that'll make you the most confiden...

In 2021, researchers noticed something unusual about the northeast corner of a cemetery in Ithaca, New York. The ground was full of tiny holes. A Cornell University team set up emergence traps and counted what came out. The answer: 5.6 million solitary bees, emerging from beneath the headstones every spring, quietly pollinating a university apple orchard 600 meters away. Then the same team found 6...

The Netherlands ships one billion flower bulbs to the United States every single year — and most of them grow into flowers that feed no bees at all. Modern hybrid tulips are sterile and produce no nectar. Daffodils contain toxic alkaloids that bees avoid. The "pollinator-friendly bulb mix" at your garden center is mostly empty flowers dressed up for human eyes. Meanwhile, bumblebee queens emerging...

Bees have five eyes, can see colors that don't exist in the human visual spectrum, and navigate by reading polarized light patterns in the sky like a living GPS. With the National Geographic Secrets of the Bees special fresh in everyone's minds, this is the episode that goes deeper — into the visual system that makes all that extraordinary bee behavior possible. And yes, it changes how you'll thin...

Exciting news — Kelly's article on the American Bumble Bee (Bombus pensylvanicus) was just published today in the Pollinator Partnership Bee Friendly Gardening Newsletter. In this short episode, she shares what's in the piece, why this bee matters, and where to read it. Head to pollinator.org or find the link in the show notes. Please consider becoming a member of the Pollinator Partnership - Bee...

One bumblebee. One wooden ball. One hundred and seventeen times - with no reward, no training, and no reason anyone could explain. In Part 2 of our bumblebee play series, we follow PhD student Samadi Galpayage, who couldn't stop thinking about the bees she'd watched rolling balls for no apparent reason. What she discovered - published in the journal Animal Behaviour in 2022 — became the first scie...

What happens when a scientist hands a bumblebee a wooden ball and a target — and offers a drop of sugar as the prize? She scores a goal. In 2017, researchers at Queen Mary University of London discovered that bumblebees could learn to roll a ball to a target by watching another bee do it first — and then improve on what they saw. With brains smaller than a sesame seed, these tiny athletes showed a...

Bumblebee queens spend up to nine months hibernating underground — and sometimes, that ground floods. A 2021 lab accident accidentally revealed they could survive a week fully submerged. A new study out this week finally explains how: underwater breathing, anaerobic metabolism, and extreme metabolic slowdown — three survival systems running at once. Kelly breaks down the science and what it means...

Dedicated to the Hatch chile pepper farmers of New Mexico and the Chihuahua desert region of Mexico. My grandmother Susie Parks was a national heroine of the 1916 Pancho Villa raid on Columbus, New Mexico — my roots in this desert go deep, and so does this story. Every pepper on Earth — Hatch green chiles, jalapeños, bell peppers, habaneros — hides its pollen inside sealed tubes that only buzz-pol...

An avocado tree produces a million flowers to make a handful of fruit — and each flower switches gender across two days. Honeybees don't even like the flowers. So who's actually pollinating your avocado toast? Meet the yellow-faced bumble bee, California's most common native bumble bee and the unsung star of avocado orchards, plus the ultra-green sweat bee, tiny carpenter bees, and hoverflies doin...

One scientist called them "a monstrous, fluffy, ginger beast." Meet the giant bumble bees — the only pollinators that can buzz pollinate tomatoes, blueberries, Hatch green chiles, cranberries, and eggplant. Honeybees can't. No robot can. And these giants are vanishing — the American bumblebee has declined 90% in 20 years. In January 2026, U.S. Fish & Wildlife proposed a nationwide conservation...

Research published in January 2025 from Penn State revealed a shocking truth: flies, the world's second most important pollinators, are more vulnerable to climate change than bees—and that threatens chocolate, mangoes, and 72% of global food crops. But almost nobody noticed. Kelly breaks down the study everyone missed, explains why flies lose motor function at temperatures 2.3°C lower than bees, e...

Think hummingbirds are the only speed demons visiting your flowers? Meet the actual fastest pollinators in North America - sphinx moths with wings that beat 85 times per second and carpenter bees that visit 5,000 flowers in a single day. In this episode, we explore the incredible physics-defying abilities of these turbocharged pollinators, from hover-flying moths with tongues longer than their bod...
