The podcast, "The Buzz on Native Bees in Your Neighborhood," is online.
"When I say 'bees,' you probably think of a neat stack of white hive boxes and the jars of honey on the store shelves, right?" Flatow began. "But there's a lot more to bees than that. Because around the world, there are over 20,000 known bee species, and 4,000 of them are native to the U.S. And while these native bees that live in the wild play a key role in pollinating our plants, they don't get a ton of recognition or support like the ones that live in a box."
Professor Williams discussed a number of bee species, including bumble bees, carpenter bees, squash bees, mining bees ("bees that burrow into the ground or soil") and mason bees and leafcutter bees.
Mason bees, Williams said, build their nests "partly out of mud, which then dries. And the leafcutter bees are chewing pieces of leaves and making their nests out of those leaf pieces, either as whole chunks of leaves or as chewed up bits of leaves. We have a series of other small to large bees that nest on the ground or nest above ground that fall into other families. But probably those are the most familiar for most people."
Williams called attention to research led by his then graduate student, and now postdoctoral fellow, Maureen Page, who compared "the quality of honey bees at pollinating flowers versus the quality of other bees. And in general, we find that honey bees are sort of equal or slightly less good than many other bees. And the old adage, the jack of all trades is the master of none--the honey bee is really that jack of all trades. It's very wide in the number of flowers that it will visit, but doesn't tend to be particularly effective on any one flower visit relative to some of the other bees we have."
The alfalfa leafcutter bee "is a really effective pollinator relative to the honeybees at pollinating alfalfa," he told Flatow.
"So your bumble bee is sort of the lab animal, then," Flatow commented. "It's not a white mouse. It's a bumble bee."
Williams agreed. "It's become a pretty useful organism for studying things in the lab. I should say the other group that we work a lot with are mason bees and leafcutter bees. And because of the way they nest, they have been really useful for studying other sorts of questions. So there are a couple of groups that we work well with."
Williams also touched on the threats faced by native bees. In addition to pesticides (insecticides, fungicides, and herbicides), "they're threatened by the loss of reliable foraging floral resources," Williams said. "They are threatened by a set of emerging diseases. And this is, again, where the honey bee gets a lot of attention, right? This colony collapse may be resulting from certain viruses, but wild bees, native bees, also have some substantial problems with certain viruses and also other kinds of pathogens."
"And then a really big one is climate change. So we have to fully recognize that changes in rainfall and also changes in temperature patterns seem to be stressing bees in different parts of the U.S., for sure."
Flatow, whose colleagues say has "revived many an office plant at death's door," asked: "Can I plant a little patch of wild flowers in a pot or in the yard and really help out?"
"This is also one of these questions that's a complex one, but we'll try not to make it too complex," Williams said. "I mean, in general, planting flowers for bees is a useful thing. The one thing we'd want to be careful about if we were planting flowers in the yard is that we were also being careful about the use of some of these chemical pesticides. But I think also recognizing the importance of natural areas and broader stewardship of habitat for bees across the landscape is really important. And this tricky one with climate change, too--what are we going to do? We don't solve climate change with the sorts of things that we would do– small-scale actions--to help bees."
"But we can do some things probably--providing shady spots, where they have what we call microclimates that are maybe protecting them from times where there are heat waves that are particularly problematic--things like that that could be useful."
Williams, who joined the UC Davis Department of Entomology and Nematology faculty in 2009, was named a Chancellor's Fellow in 2015, a five-year program supporting his research, teaching and public service. He was named a a Highly Cited Researcher by Clarivate Analytics in 2018, and a Fellow of the California Academy of Sciences in 2021.
A native of Madison, Wisc., he received his doctorate in ecology and evolution from Stony Brook University, New York in 1999.

The open house, held from 1 to 4 p.m., Sunday, Aug. 27, drew guests of all ages.
Tabatha Yang, the Bohart Museum's education and outreach coordinator, wore a green mantis costume to greet guests and show them the Madagascar hissing cockroaches and stick insects in the live petting zoo.
UC Davis alumnus Kevin Murakoshi of Davis arrived to gift the museum with intricate origami mantises that he crafted from "mantis-green" paper--one sheet per mantis. Murakoshi, a former UC Davis employee (computer research specialist) is the principal solutions architect at Amazon Web Services.
Photographer Ian Alexander Levin of Sacramento displayed his enlarged images of mantises, including one of a mantis eating a bee that drew "oohs" and "aahs." He owns a child day care center in Sacramento and likes to share his finds in the "Critter Corner" of the center. Levin is the administrator of the Facebook page, SacraMantis.
Skylar Primavera, who studied praying mantises while attending UC San Barbara (bachelor's degree in biology, 2020) displayed a live mantis as well as life-cycle models (ootheca to the adult), and answered questions about the predatory insect.
Melody Ruiz, a third-year entomology student, coordinated and staffed the family arts-and-crafts table, featuring "Mantis on a Stick." Using a green paper cutout of a mantis head attached to a popsicle stick, the budding artists colored the compound eyes and added pipe cleaners and other decorations as finishing touches.
Lynn Kimsey, director of the Bohart Museum, and Brennen Dyer, collections manager, welcomed the crowd and answered questions. The Lepidoptera crew of Jeff Smith (curator of the Lepidoptera collection), Greg Kareofelas and Brittany Kohler showed guests assorted butterfly specimens collected world-wide.
A computer screen showcased the work of UC Davis doctoral alumnus Alex Wild, curator of entomology at the University of Texas, Austin, and Kathy Keatley Garvey, communications specialist, UC Davis Department of Entomology and Nematology.
Guests viewed display drawers of both native and non-native mantises. At least 9 species of mantises in California, according to one display.
Five are native:
- The Arizona or bordered mantid (Stagmomantis limbata)
- Bistanta mexicana
- California mantid (Stagmomantis wheeleri=S. californica)
- Litaneutria ocularis=Litaneutria obscura
- Small gray mantid (Litaneutria pacfica)
Four are introduced:
- Chinese mantid (Tenodera sinensis)
- European mantid (Mantis religiosa)
- Mediterranean mantid (Iris oratoria)
- South African mantid (Miomantis caffra)
The Bohart Museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis, houses a global collection of eight million insect specimens, plus a live petting zoo and an insect-themed gift shop, stocked with t-shirts, hoodies, books, posters, jewelry, collecting equipment and more.
Professor and renowned entomologist Richard Bohart (1913-2007), a member of the UC Davis Department of Entomology (now the Department of Entomology and Nematology) faculty for more than 50 years, founded the museum in 1946.

The Bohart Museum of Entomology is hosting an open house, themed "Praying Mantises," on Sunday, Aug. 27 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. It is free and family friendly.
When asked what's fascinating about praying mantises, Lohit Garikipati, UC Davis entomology graduate (bachelor of science degree, 2019) wrapping up his master's degree with biologist Christopher Oufiero at Towson University,Towson, MD, said:
"What's fascinating about them... hard to pick just one thing! If I had to choose it would be their general awareness about the environment they are in. They are always watching, always waiting, and adjust their posture, behavior, and movement based on various environmental stimuli. They engage in some of the most interesting predatory behaviors; pouncing, lunging, spearing (yes, spearing!) and sometimes throwing themselves off of perches to secure potential prey. Few flightless predators can catch prey out of the air on the wing but many specialized species are more than capable of doing so. They are the insect equivalent of cats in many ways, but with some weird adaptations!"
Garikipati, who participated in many Bohart Museum open houses while a student at UC Davis, won't be at the open house on Aug. 27 but he will be their spirit. He plans to obtain his doctorate in entomology.
According to Kris Anderson of Las Vegas, an alumnus of Cornell University (master's degree in entomology) and author of Praying Mantises of the United States and Canada: "There are just 28 species of Mantodea found within the United States and Canada, the 7 largest of which are invasive species from other parts of the globe."
Some myths about praying mantises, as related by Anderson in his book, available on Amazon:
Myth: "Mantises sway back and forth while crawling to imitate vegetation blowing in the wind."
Truth: "The peering movement of mantises, demonstrated by the swaying back and forth of their body while ambulating or preparing to leap/take flight, is a behavioral adaptation to gain depth perception of their surroundings and has nothing to do with mimicry. Mantises blend into their environment by remaining motionless against a substrate that they morphologically resemble—not by moving. Peering movements causes the retinal images of nearby objects to be displaced more quickly than those of more distant objects, thus allowing the mantis to gain depth perception of its environment as it navigates forward."
Myth: "Mantises grab insects and immediately bite the neck/head to quickly kill their prey."
Truth: "The spinose forelegs of praying mantises are used to hold onto and prevent their prey from escaping. Once secured in their grip, the mantis will pull the prey forward and begin to meticulously chew upon whatever body part of the prey item is closest to their mouth—be it a leg, a wing, the thorax, abdomen, or head. No specific body region is exclusively targeted and the prey is always eaten alive, bit by bit, dying a slow death."
Myth: "Female mantises cannibalize the males while mating."
Truth: "With over 2,400 species of Mantodea worldwide, only a small fraction of species regularly engage in sexual cannibalism. Most do not. Of those that engage in this practice, the occurrence is not inevitable, as males typically escape and may mate with other partners."
