This episode is about what those ground-nesting bees need from a patch of bare earth: the right soil texture, a bit of slope, sun, and above all the right dampness held steady across the ten or eleven months they spend below the surface. It's also about what disappears when that ground gets covered — by any large development, and increasingly by the data centers going up fast across the country. The honest catch: nobody has studied the bee side of that build-out yet. Studies take time. The mechanism is clear; the measurements aren't there.

KEY SOURCES

Proportion of ground-nesting bees

    • Antoine CM, Forrest JRK. "Nesting habitat of ground-nesting bees: a review." Ecological Entomology 46:143–159, 2021. DOI: 10.1111/een.12986 — reports the primary range: Cane & Neff (2011) put underground nesters at 64%; Harmon-Threatt (2020) at 83% (excluding parasitic species). Use "most" on air — do not state a single percentage as fact. The popular "70%" (Xerces, USDA) sits inside this range but isn't the precise figure.

Soil texture and species specificity

    • Cane JH. "Soils of ground-nesting bees: texture, moisture, cell depth and climate." Journal of the Kansas Entomological Society 64:406–413, 1991 — sand percentages of 34–94% across 32 species; larger bees toward clay-richer soils.

Nest-site characteristics (bare ground, temperature, hardness, moisture)

    • Kordges et al. "Barefoot Trees for Bees: Nesting Site Characteristics of the Ground-Nesting Bee Andrena vaga in an Urban Environment." 2025. PMC12535216 — measured nesting sites vs. uncolonized controls; distinguishing factors were bare-ground proportion, soil temperature, soil hardness, and water content. This is the Segment Two/Three anchor.

Nesting depth and bare-soil requirement

    • Vaughan M et al. "Enhancing Nest Sites for Native Bee Crop Pollinators." USDA Agroforestry Note 34 / Pollinator Partnership — brood cells 6 to 36+ inches down; direct soil-surface access required; sloped/well-drained sites preferred.

Data center land/water footprint (context only — none of these address bees)

Yes, and it's more brutal than most people imagine. In this episode: a desert bee whose large-headed males duel underground in fights that always end in death, an Australian burrowing bee whose males wrestle violently on open ground while birds pick them off, and two stingless bee species that wage genuine warfare with thousands of casualties and hostile nest takeovers. Plus the quieter, constant conflict at solitary bee nest entrances, and an honest look at where the “bee fight club” comparison holds up and where it falls apart. Wonder-first, science-grounded, and no honey bees required.

It's Not Mosquitoes]]>That snap from the bug zapper on the patio? It's usually killing a night pollinator and almost never a mosquito. When researchers counted every insect six zappers killed over a full summer, only two-tenths of one percent were biting flies — the rest were harmless aquatic insects, natural pest-controllers, and the night-flying moths that pollinate in the dark while we sleep. This episode unpacks why the device is aimed at the wrong target from the start (mosquitoes don't hunt by light — they hunt by the CO₂ and heat your body gives off), what's really dying in that electric grid, and the simpler, cheaper things that actually keep the biters off you. A short, clear look at a familiar summer sound — and the quiet cost of that glowing purple lamp.

Not metaphorically — an actual transparent, waterproof, antimicrobial film that she paints onto the walls of her underground brood cells with a forked tongue.

Chemists have identified the compounds. Industry wants the material for biodegradable packaging. Nobody has been able to reproduce it.

This week: the cellophane bees of the genus Colletes, the Dufour's gland secretions they polymerize into natural cling wrap, how to spot a nesting aggregation, and why the low cloud of bees hovering over a bare patch of lawn in early spring is one of the most misunderstood sights in North American nature.

Meet the wool carder bee: a thumbnail-sized native that scrapes the soft fuzz from fuzzy-leaved plants like lamb's ear, rolls it into little cotton balls, and felts them into a row of downy capsules where her young grow up. We get into how she "cards" plant wool the way spinners comb it for yarn, why a leaf's fuzz is really the plant's armor turned into a baby blanket, and the surprisingly fierce males who body-slam bumble bees to guard a patch of flowers. There are more than 160 kinds of wool carder bees in the world, and around 29 of them live right here in North America. Plus, the wool carder on your garden lamb's ear is probably a European transplant — but the West has natives of its own. Come find one.

Or Did It?]]>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 Washington in over a century. The real revelation isn't that these bees came back. It's that they never left. We just stopped looking.

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 under your feet. They are docile and some of the best pollinators in the world. Four thousand shapes, four thousand quiet lives. Once you see them, you can't stop.

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: traplines, floral constancy, the multi-scale memory that makes it all work, and why the technology to track solitary native bees is only now catching up to the questions scientists most want to answer. Plus: what the flowers have to do with all of it.

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), the loyal little crowds of males that bed down on the same stems night after night, and how a cold morning can leave a bumblebee frozen in place, waiting for the sun. Best of all, this is one wonder you can confirm with your own eyes tonight. No lab required. Just a flower and the right hour.

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 living across the United States.

From the Suckley cuckoo bumblebee (Bombus suckleyi) of the Mountain West to the lemon cuckoo bumblebee (Bombus citrinus) of the eastern deciduous forests, this episode tours every cuckoo bumblebee in North America: Bombus suckleyi, Bombus insularis, Bombus flavidus, Bombus bohemicus, Bombus citrinus, and the vanishing Bombus variabilis.

We explore the chemistry of infiltration — how cuticular hydrocarbons let a cuckoo bumblebee queen smell her way into a host colony undetected. We unpack the violent takeover: the queen-on-queen combat, the reinforced exoskeletons and oversized stingers, and the pheromonal reproductive suppression that follows. And we end with the story of the variable cuckoo bumblebee, a southern species that may already be functionally extinct across much of its former American range — a ghost that lived by erasing other bees, and has now been erased itself.

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 alone cannot match.

Episode 41 follows olive trees from California's Central Valley to Georgia's coastal plain, and the native bee communities — mining bees, sweat bees, carpenter bees — that found them.

Scientists Just Found Out!]]>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 gets too hot, they fan their wings — a living air conditioning system. And when heat events become extreme, the entire colony redirects its labor away from foraging to cooling, with cascading effects on pollination. Kelly breaks down the science of bumble bee thermoregulation, the critical role of underground nest sites, and what this research means for how we think about wild bumble bee habitat. It's not just about flowers. It's about what's happening below the surface.

Surprising Science Says Yes]]>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 finding it? In this episode we dig into the surprising science of grass pollen as bee food, the new (and shockingly recent) research showing five genera of bees collecting pollen from a single turfgrass species, what cues bees use to spot grass anthers in a sea of green, and why the lawn under your feet might be quietly feeding the bees you're trying so hard to save with your wildflowers. Spoiler: the cemetery bees from Episode 37 were in on this all along.

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 651,440 more bees in a suburban lawn — collecting grass pollen nobody knew they wanted. These populations are hiding everywhere in plain sight, in the patches of ground we've never thought to study. And the safest place a wild bee can nest might just be the one piece of land nobody ever builds on.

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 scientific proof that insects play. Not for food. Not for survival. Just for the joy of it. We dig into what that means for how we understand bee emotion, insect sentience, and the surprisingly blurry line between creatures that feel and creatures we've always assumed don't. If this episode doesn't change the way you look at the next Bumblebee you see, nothing will.

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 level of social learning and cognitive flexibility that stunned the scientific world. But the most surprising discovery? Some bees kept rolling the ball even when no reward was coming. That's where this story gets really interesting. Tune in for Part 1 — and stay for the twist that launched one of the most fascinating bee studies ever published.

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 for bumblebee conservation as flooding events increase.

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-pollinating bees can open. Honeybees can't do it. Remove the bees and you lose two-thirds of your pepper crop. The global pepper market is worth over $60 billion, and the bees behind it are declining. This is the story nobody at the Hatch Chile Festival is telling.

While industrial agriculture creates flowering deserts, urban balconies, rooftop gardens, and community plots are supporting surprising bee diversity. Research shows some cities harbor more native bee species than surrounding farmland. We explore why concrete jungles are working for pollinators, which species are thriving in cities, and how anyone—even without a yard—can create powerful pollinator habitat in just 10 square feet. From Chicago high-rises to San Francisco fire escapes, discover why your balcony might be more valuable to native bees than a thousand acres of corn.

She's built for it: brushes on her front legs, heavy-duty pollen baskets for oversized cactus grains, and the ability to recognize her host plant by chemistry alone — after she lands on it. In this episode we look at what specialization actually costs and what it buys. Why open, unfussy barrel cactus flowers turn out to be pollinated almost entirely by specialists while common generalist bees stay away. Why some desert bees keep offspring underground for more than one winter as insurance against a failed bloom. And why commercial growers can't simply buy this pollinator the way they buy honey bee hives.

  • McIntosh, M. E. — pollen-preference cage experiments: novel pollens accepted to a degree, Sphaeralcea (ancestral host) significantly accepted, but naive D. rinconis did not initiate nesting on Sphaeralcea alone; rejection typically occurred after landing, implicating chemosensory/tactile recognition of pollen rather than floral cues.

For decades, they claimed citrus trees were self-pollinating and didn't need insects. New research proves otherwise: without pollinators, citrus production drops 58%. Native bees increase fruit set, while excessive honeybees actually decrease fruit quality. We expose the citrus conspiracy and reveal why your backyard lemon tree needs native pollinators way more than anyone admitted. The science is clear, and it changes everything.

Chestnuts are pollinated by FLIES and BEETLES—not bees. Pecans rely entirely on wind. Walnuts use wind with help from cold-hardy native bees. In this special holiday episode, we explore the surprising, unglamorous pollination strategies of nut trees. Spoiler: it's not the story anyone expects, but it's the one that actually works.

Journal of the Kansas Entomological Society, 54(2), 359–377. — individual visits to pistillate flowers by each species were equivalent; honey bees preferred pistillate flowers while squash bees preferred male flowers; most pollination was accomplished by squash bees before honey bees appeared in numbers.

They aren't pest damage at all — they're evidence of one of the most precise construction projects in the insect world. Leafcutter bees shear pieces of leaf with toothed mandibles, carry them off, and use them to build overlapping, water-resistant nursery cells inside hollow stems and old beetle tunnels. This episode covers how to tell a leafcutter cut from actual pest damage, why the pollen brush on a leafcutter's abdomen makes her a more effective pollinator than a honey bee, when and where to watch for her, and why the genus Megachile includes both the largest bee on Earth and a non-native species now spreading across North America.
