While honey bee workers are all the same size, that’s not true for bumblebees. Scientists aren’t sure what’s behind the wide variety in bumble body sizes, but a new UC Riverside project aims to find out.

Certain crops, like greenhouse tomatoes, eggplant, peppers, and blueberries, rely on bumblebees for a style of pollination that only bumblebees can perform. Among growers, the preference can be for bigger-bodied bumblebees because they’re thought to be more efficient pollinators.

Enabled by a $750,000 grant from the National Institute of Food and Agriculture, the research team will investigate factors suspected of influencing bumblebee biology and body size, including climate change, wildfires, and the presence of nearby honey bee colonies.

In many cases, individual animals are born smaller when their habitat has less nutrition available. The researchers want to know if this is also true for bees. “One idea is that honey bees are taking more food resources, resulting in smaller bumbles. This is part of what we will be testing,” said UCR entomologist and project lead Hollis Woodard.

To test this, the researchers will collect bumblebee size data over the next four years from places both with and without honeybees nearby. “It’s hard to find anywhere in the lower 48 without either managed or feral honey bees. For this reason, we’re headed to Alaska for part of the study,” Woodard said.

Fire may also play a role in bumblebee development. Some research has shown that bumblebees are born bigger, and in higher numbers, during the years following a wildfire. Since wildfires are common in California, the research team will also be collecting data from places throughout the state with different types of fire histories.

“Fires are good in some ways for bees,” Woodard said. “As the land recovers from the burn, a lot of flowers appear, offering food.”

In addition to the mystery of what influences the bees’ body size, it’s also unclear what role size plays in a bumble colony. While all bumblebee workers perform the same functions, variation in size could allow the hive as a whole to collect pollen from a wider variety of flowers.

Though bigger bees can collect more pollen, they might not be right for every plant species. For some flowers, especially those that are trumpet-shaped, smaller bumblebees are better pollinators.

“There are theories that bumblebee sizes are just random, or that it’s just generally good to have variation,” Woodard said. ‘Right now, we don’t yet know exactly what this variation in size does for colonies.”

In addition to benefitting crop growers, the team’s findings could ultimately benefit the bees themselves. “Any insights we gain into factors affecting the bumblebees could help us better understand how to bolster their dwindling populations,” Woodard said. “Helping them in turn helps ensure the health of wildflowers, as well as our food supply.”

Beekeeping is an Example

NEWS PROVIDED BY

CGTN (Chinese Global Television Network)

BEIJING /PRNewswire/ — Liu Jinliang, a second-generation beekeeper in Miyun District, the northeastern suburb of Beijing, practices multi-box beekeeping. He is China’s first beekeeper to successfully utilize the technique, introduced by the district government in 2016.

It took the young bee farmer five years to fully implement the new technique, and now it is helping his family and local beekeepers live a “sweet” life.

Spurred on by Liu and the local government, around 30 percent of bee farmers in Miyun have now adopted the new technique, greatly boosting the output and quality of their honey. Over 360 low-income farmers in Miyun have shaken off poverty since joining the beekeeping project.

“Through my example, I can motivate people around me. And those people can empower other people around them as well. In this way, we can achieve common prosperity,” Liu told CGTN.

The beekeeping industry in Miyun generated around 130 million yuan ($18.91 million) in revenue in 2020, an increase of 19.3 percent over 2019. Encouraged by what has been achieved in Miyun, more and more bee farmers across China have turned to the multi-box beekeeping technique to raise their honey output while improving quality.

Chinese President Xi Jinping once quoted an ancient Chinese proverb, “The key to running a country is to first enrich the people,” to explain why the country is striving for common prosperity. Liu’s story gives a glimpse of China’s exploration of the paths to achieve that goal.

People-centered philosophy

The saying, which comes from Shiji, or Records of the Grand Historian, a monumental history book of ancient China compiled about 2,000 years ago, sets forth the traditional Chinese philosophy of governance: the common people are considered the foundation of a country, and only when the people prosper can the country prosper.

This is a classic piece of Chinese wisdom, and it has become part of the governance philosophy of the Chinese government in modern times.

When quoting the saying at a gathering to mark China’s poverty alleviation accomplishments and honor model poverty fighters, President Xi pledged the country would adhere to the people-centered development philosophy and unswervingly follow the path of common prosperity.

“We have always remained committed to standing on the side of the people and consistently stressed that eradicating poverty, improving people’s lives, and achieving common prosperity represent the essential requirements of socialism,” said Xi.

Behind Liu’s success is the Miyun district government. It has helped local beekeepers learn advanced apiculture techniques and provided them with high-quality queen bees at no charge.

To better help beekeepers, the district government has also provided financial aid to support about 30 projects in the sector, with an investment of about 100 million yuan, to help make commercial beekeeping standardized and industrialized.

Researchers shed more light on how insects pollinated the very first flower. (KarinD/Adobe)

The Botanic Gardens of Sydney has published a paper with researchers from Macquarie University and Western Sydney University, shedding more light on one of the earliest origin stories about the birds and the bees.

A large dataset examining what pollinators are relied on by 1,160 species of different flowering plant families has been examined to determine the long relationship insects have had with some of the earliest flowers.

By examining a state-of-the-art ‘evolutionary tree’, researchers believe that insects have pollinated angiosperms, or flowering plants, over most of the plant’s 140-million-year evolution.

The findings of the botanical science study were published in the journal New Phytologist on Tuesday.

Macquarie University PhD student Ruby E. Stephens was the lead author of the paper. She explained the evolutionary tree showed when certain plant families evolved, which helped to advance the understanding of plant history.

“This is a significant discovery, revealing a key aspect of the origin of almost all plants on Earth today,” Stephens said.

“By running different models, we can map backwards from what pollinates a plant in the present, to what might have pollinated the ancestor of that plant in the past.”

A total of 90% of today’s flowering plants are pollinated by insects and the colour, scent, and even sexual mimicry of these many flowers have evolved to attract insects.

However, a number of other flowers do not depend on insects and instead rely on vertebrate animals, wind or even water to transport pollen.

According to researchers, until this study it was not clear which form of flower pollination came first.

The authors further believe that the first flower was also likely to be insect-pollinated.

“Plants are the lifeblood of our planet, and our study highlights the importance of insects to plant reproduction throughout Earth’s history,” Stephens said.

Dr Hervé Sauquet from the Botanic Gardens’ plant discovery and evolution team noted that in addition to insect pollinators, the research uncovered how other forms of pollination changed over time.

Wind pollination, for example, was more likely to evolve in open habitats towards the poles. Meanwhile, locations such as closed rainforests near the equator were where animal pollination was more likely to take place.

“Pollination from vertebrate animals like birds, bats, small mammals, even lizards, has evolved and reverted numerous times throughout history,” Sauquet said.

“Wind pollination has also evolved many times, but it is harder to reverse — once plants go pollination by wind, they rarely go back.”

Washington University biology expert Professor Susanne Renner said the findings confirmed insects pollinated angiosperms for most of this plant lineage’s history.

“This underscores the need for the conservation of insects — their role as pollinators is essential for the continued existence of plants,” she said.

Two pending endangered species listings for pollinators can have major impacts on the almond industry as many almond growers have added pollinator forage such as blooming cover crops, hedgerows and floral strips to add value to their operation. Josette Lewis, Almond Board of California chief scientific officer, said 2023 will be a decisive year for the endangered listing of the monarch butterfly and native bees in California, which leads to questions for growers. However, work is underway to protect producers if this happens and Lewis took some time to answer those questions.

Q – What is the status of the monarch butterfly being listed as an endangered species?

Lewis – A couple of years ago, the U.S. Fish and Wildlife Service made the decision that monarch butterflies were warranted as an endangered species, but they had other priorities at the time. So, while it was not going to be listed, they are required by law to revisit that decision by the end of this calendar year.

Q – If they do get listed as endangered, what does that mean for an almond grower? 

Lewis – It means a couple of things:

The first is that a lot of almond growers have stepped up and added pollinator forage, flower resources and habitat to their farms and land around their farms. We’ve seen a great response in terms of the number of growers who have registered as Bee Friendly Farms, who are putting in flowering cover crops, and working with organizations like Monarch Joint Venture to specifically put in monarch habitat around their ranches. Several handlers are working with growers on pollinator habitat too, as it has value to some almond buyers.

For those growers who have stepped up, we want to make sure that they are protected if the monarch is listed as an endangered species. So, if they accidentally harm the caterpillars or the butterflies themselves, we want to make sure that they are not breaking the law because they’ve done such a good job of adding that forage into their operation.

The other issue, on an industry level, is that the U.S. Environmental Protection Agency – who has to approve every crop production product our industry can use – was also mandated by law to increase their review of the potential negative impacts of pesticides on endangered species.

We know that if the monarch is listed, some of the products we use when they come up for re-registration, or any new products that are developed and need to be registered, will have extra scrutiny for their potential impact and could involve more restrictions on the use of those products.

Q – So it sounds like this could be a legal concern for growers and a bigger concern of more regulation on certain products if the monarch gets listed as endangered. What is ABC doing to address these two concerns? 

Lewis – We’ve been working with the Almond Alliance of California, other California agricultural interest groups, and some conservation groups who have been valuable partners of the California almond industry to negotiate a conservation agreement with the U.S. Fish and Wildlife Service that would protect growers who have monarch habitat if they accidentally harm any of those monarch butterflies or larvae.

The way those agreements work is that we have to show that there’s a net benefit to the pollinators. Things like adding flowers and habitat for monarch butterflies, and in exchange for doing those good things, in this agreement you’re then protected if you accidentally harm monarchs.

Also, as part of those negotiations, we are including the kind of practices that reduce risks of crop protection products and try to demonstrate that we can use those safely and still have a net benefit to monarch butterflies.

Q – “Net benefit” seems like the important term in this conversation. ABC grower-funded research has already been completed in this realm and showed pollinator gains from increased habitat outweighs the risk. Can you explain that?  

Lewis – That’s right. ABC funded research with a native bee expert at UC Davis, which was published last year, showed that when farmers add floral strips – such as wildflower strips, part of a hedge row or just wildflowers near the outside the orchard – the added food for native bees helps protect those bees from the impacts of pesticide exposure. So, there is a net benefit to those native bees.

This research provides good, peer-reviewed and science-based evidence that shows these kinds of activities we have seen many growers in our industry do have a net benefit.

Q – ABC and partners are already addressing these concerns, which is good because more and more growers and handlers are utilizing this practice, right?

Lewis – A lot of growers have been looking at cover crop and adding that into their orchard management. This year in particular, I heard a grower who planted cover crops talk about how the water didn’t stay standing in their orchards back in early spring when we had so much rain, rather that the water infiltrated and drained much more quickly.

There are agronomic benefits from the practice that are worth considering, in addition to benefits to pollinators. And adding more permanent habitat outside the orchard is another area where a number of our handlers in the industry have seen a market value. Buyers want to know that they have a supply chain of almonds that allows biodiversity and a healthy ecosystem on the farm. Some handlers have really leaned in with their growers and are encouraging those kinds of practices, and that’s added certain value to both growers and handlers.

Without bees, there is no food, so keeping hives healthy is of utmost importance. That job is becoming more difficult thanks to an outbreak of disease and the effects of climate change.

That’s where special apiary inspectors come in, who check on the health of keepers’ bees to help prevent the spread of honeybee diseases and pests.

Marie Cairns, a bee keeper who runs a small apiary in the Cowichan Valley, had her hives checked on Friday by Tara Galpin, an apiary inspector for South Vancouver Island and the Gulf Islands.

“First of all, it was all about the pollination, but then the more you learn about bees the more fascinating they are,” Cairns said.

Cairns has been bee keeping in the valley for nine years. She got her inspection for free, as any bee keeper can, so she can sell some of her hive.

“You have bees and you want your own bees to stay healthy, so you want their bees to be healthy because they fly and bring back disease if you don’t or mites or anything else,” she said.

Galpin is looking for a few different diseases and pests. One that comes up often is the varroa mite, a parasitic mite that feeds on honey bees and causes a disease called varroosis.

“They feed out the fat body of the bee, so it’s like if we had the size of a rat on our human body feeding on our liver,” Galpin explained.

Unfortunately, Cairns’ bees had too many mites. “My first time failing,” she said.

But this experienced bee keeper is unfazed, and will work with the inspector to apply the appropriate treatment.

Galpin says unpredictable spring weather due to climate change—that have been cooler and damper—is helping to spread fungal disease and doesn’t allow bees to forage for food when they need it most.

Keeping bees in good shape is important, as along with other native pollinators they play a key role in sustaining B.C.’s food system, and contribute an estimated $250 million to the province’s economy.

The inspector says losses this year in bee colonies is between 30 to 40 per cent—climate change and the spread of disease keeping the pressure on bees and their keepers.

“More than anything, we need diversity of plants for our bees to forage from and diversity in our food landscapes,” she said.

Importing bees plays a major role in maintaining the bee population across Canada, and combined with the work of inspectors like Galpin, they’re ensuring bees keep food on our table.

Beekeepers from Best Bees inspect two hives on the roof of the Warren Rudman U.S. Court House

CONCORD, N.H. — While judges, lawyers and support staff at the federal courthouse in Concord, New Hampshire, keep the American justice system buzzing, thousands of humble honeybees on the building’s roof are playing their part in a more important task — feeding the world.

The Warren Rudman U.S. Court House, in Concord, N.H. The roof of the building hosts two bee hives, a part of a national effort to increase the population of pollinators.

The Warren B. Rudman courthouse is one of several federal facilities around the country participating in the General Services Administration’s Pollinator Initiative, a government program aimed at assessing and promoting the health of bees and other pollinators, which are critical to life on Earth.

“Anybody who eats food, needs bees,” said Noah Wilson-Rich, co-founder, CEO and chief scientific officer of the Boston-based Best Bees company, which contracts with the government to take care of the honeybee hives at the New Hampshire courthouse and at some other federal buildings.

Bees help pollinate the fruits and vegetables that sustain humans, he said. They pollinate hay and alfalfa, which feed cattle that provide the meat we eat. And they promote the health of plants that, through photosynthesis, give us clean air to breathe.

Yet the busy insects that contribute an estimated $25 billion to the U.S. economy annually are under threat from diseases, agricultural chemicals and habitat loss that kill about half of all honeybee hives annually. Without human intervention, including beekeepers creating new hives, the world could experience a bee extinction that would lead to global hunger and economic collapse, Wilson-Rich said.

The pollinator program is part of the federal government’s commitment to promoting sustainability, which includes reducing greenhouse gas emissions and promoting climate resilient infrastructure, said David Johnson, the General Services Administration’s sustainability program manager for New England.

The GSA’s program started last year with hives at 11 sites.

Some of those sites are no longer in the program. Hives placed at the National Archives building in Waltham, Massachusetts, last year did not survive the winter.

Since then, other sites were added. Two hives, each home to thousands of bees, were placed on the roof of the Rudman building in March.

The program is collecting data to find out whether the honeybees, which can fly 3 to 5 miles from the roof in their quest for pollen, can help the health of not just the plants on the roof, but also of the flora in the entire area, Johnson said.

“Honeybees are actually very opportunistic,” he said. “They will feed on a lot of different types of plants.”

The program can help identify the plants and landscapes beneficial to pollinators and help the government make more informed decisions about what trees and flowers to plant on building grounds.

Best Bees tests the plant DNA in the honey to get an idea of the plant diversity and health in the area, Wilson-Rich said, and they have found that bees that forage on a more diverse diet seem to have better survival and productivity outcomes.

Other federal facilities with hives include the Centers for Medicare and Medicaid Services headquarters in Baltimore; the federal courthouse in Hammond, Indiana; the Federal Archives Records Center in Chicago; and the Denver Federal Center.

The federal government isn’t alone in its efforts to save the bees. The hives placed at federal sites are part of a wider network of about 1,000 hives at home gardens, businesses and institutions nationwide that combined can help determine what’s helping the bees, what’s hurting them and why.

The GSA’s Pollinator Initiative is also looking to identify ways to keep the bee population healthy and vibrant and model those lessons at other properties — both government and private sector — said Amber Levofsky, the senior program advisor for the GSA’s Center for Urban Development.

“The goal of this initiative was really aimed at gathering location-based data at facilities to help update directives and policies to help facilities managers to really target pollinator protection and habitat management regionally,” she said.

And there is one other benefit to the government honeybee program that’s already come to fruition: the excess honey that’s produced is donated to area food banks.

Dissimilarity of brain GRN architecture between soldiers and foragers is greater in high-aggression honeybee colonies. Credit: Nature Ecology & Evolution (2023). DOI: 10.1038/s41559-023-02090-0

Collective behaviors are present across many different animal groups: schools of fish swimming in a swirling pattern together, large flocks of birds migrating through the night, groups of bees coordinating their behavior to defend their hive.

These behaviors are commonly seen in social insects where as many as thousands of individuals work together, often with distinct roles. In honey bees, the role a bee plays in the colony changes as they age. Younger bees perform duties inside the hive, such as nursing and wax building, while older bees transition to roles outside of the hive, either foraging for food (foragers) or defending the colony (soldiers).

What determines whether older bees become foragers or soldiers is unknown, but a new study published in Nature Ecology and Evolution explores the genetic mechanisms underlying the collective behavior of colony defense, and how these mechanisms relate to the colony’s overall aggression.

“Honey bees do not have a size-based division of labor, like you might see in termites or ants,” said Ian Traniello, former graduate student at University of Illinois Urbana-Champaign, now an associate research scholar at Princeton University and first author on the study.

“If you ask anyone off the street to guess which ant is a soldier versus a forager, they probably will guess it right 100% of the time, because the soldiers are huge. Honey bees instead have an age-based division of labor, where older bees tend to be foragers or soldiers, both of which are dangerous and potentially lethal roles.”

A genome-wide association study conducted previously on a sub-species of honey bee in Puerto Rico that had evolved to be less aggressive in recent years, revealed strong associations between variation in the sequence of some genes and the level of overall colony aggression. Researchers called these “colony aggression genes.”

In the current study, researchers compared the expression and regulation of genes in the brains of soldiers and foragers, and across colonies that varied in aggressiveness. Researchers measured colony aggressiveness by counting the number of stings on suede patches placed outside the hives after a disturbance.

They identified soldiers as the bees that attacked the patches and foragers as the bees that returned to the hive with pollen. The researchers then used single-cell transcriptomics and gene regulatory network analysis to compare the brains of forager and soldier bees, from low and high aggression colonies.

The researchers found that, although there were thousands of genes in the brain that differed in their expression between soldiers and foragers, none of them were part of the colony aggression gene list. However, when they created models of brain gene regulatory networks, which control when and where specific genes are expressed, the researchers found that the structure of these networks differed between soldiers and foragers—and the differences were bigger when the soldiers and foragers came from a more aggressive colony.

“What we think is happening is that the regulation of genes associated with collective behavior affects the mechanisms that underlie division of labor,” Traniello explained. “So, colonies can become more or less aggressive by influencing the aggression level of the individuals within that colony. Basically, a forager may be more or less likely to transition to a soldier-like state if the environment calls for it.”

The findings highlight the importance of gene regulation to our understanding of the relationship between genes and behavior.

“While a few studies have found potential heritable differences between soldiers and foragers, this study demonstrates that older honey bees may have the potential to take on either role,” said Gene Robinson (GNDP), IGB Director and author on the paper. “In colonies that are more aggressive, likely due to increased danger in the environment, older bees may just be more predisposed to become soldiers to help defend the colony.”

Plans for future directions include developing functional tests to explore the role of the gene networks identified in the study, and to identify spatially where they are being expressed in the brain. Traniello says that he looks forward to exploring these new questions.

“We have extraordinary technologies to probe genes and behavior at an unprecedented scale, both with single-cell and, now, spatial transcriptomics,” Traniello said.

“These give us new means for understanding old questions, like the relationship from individual to collective, or the relationship between genotype to phenotype. It’s exciting to be able to take these tools and apply them in naturalistic contexts, and I hope this work inspires others to do the same.”

The U.S. Environmental Protection Agency (EPA) is taking an important step to determine whether the herbicide dimethyl tetrachloroterephthalate (DCPA) can continue to be used safely in light of significant health risks identified. The Agency is releasing and requesting public comment on an Occupational and Residential Exposure (ORE) assessment on pesticide products containing DCPA, showing risks to workers and others exposed to the pesticide, with the most serious of risks to the fetuses of pregnant individuals. Additionally, EPA is releasing a companion document summarizing EPA’s ongoing review of DCPA, the health risks the Agency has identified, and potential next steps for the Agency. Given the potential for serious, permanent, and irreversible health risks, EPA is considering whether feasible mitigation measures exist that would address these potential risks or whether canceling the registration of all products containing DCPA is necessary. Given the potential that cancellation of this pesticide could take several years to complete, EPA is releasing this assessment in order to provide the public with timely information about its risks.

Background on DCPA

DCPA is an herbicide registered to control weeds in both agricultural and non-agricultural settings. Agricultural crops include cole crops (e.g., broccoli, Brussels sprouts, cabbage), onions, and other vegetables. Non-agricultural uses include non-residential turf and ornamentals.

DCPA is currently undergoing registration review, a process that requires re-evaluation of registered pesticides every 15 years to ensure that as the ability to assess risk evolves and as policies and practices change, pesticides continue to meet the statutory standard of causing no unreasonable adverse effects on human health or the environment.

The data EPA examined showed that the dose that caused adverse effects in the fetuses of pregnant rats exposed to DCPA was very low, and these effects were observed at a dose lower than the dose that affected the pregnant rats themselves. Significant thyroid hormone changes were observed in the fetuses in a 2022 study that EPA had ordered the registrant for DCPA to conduct in 2013. In general, changes in fetal thyroid hormones are linked to low birth weight, impaired brain development, decreased IQ, and impaired motor skills observed later in life. These thyroid hormone effects are harmful to the fetuses of individuals of child-bearing age that could be exposed to DCPA. The differences in the doses affecting the pregnant rats and their fetuses, extrapolated to humans, mean that a pregnant individual could be exposed to DCPA without experiencing adverse health effects to their own body, while the fetus being carried could experience permanent and significant lifelong adverse effects.

In 2013, the Agency issued a Data Call-In to the pesticide registrant, AMVAC, requiring it to submit more than 20 studies to support the existing registrations of DCPA. Between 2013 and 2021, numerous studies submitted by AMVAC were deemed insufficient by the Agency, and some studies, including the thyroid toxicity test, had not been submitted. In April 2022, EPA issued a Notice of Intent to Suspend (NOITS) for the DCPA technical-grade (high-concentration) product based on the registrant’s failure to submit the complete set of required data, leaving large uncertainties in risk estimates, including data on DCPA’s thyroid toxicity. In August 2022, after the issuance of the NOITS, the Agency received the thyroid toxicity data that showed the significant changes in the fetal thyroid effects discussed above.

Occupational and Residential Exposure Assessment and Companion Document

The Agency found that based on the currently allowed uses of DCPA, there is potential for some people to be exposed to DCPA at levels approaching those that, based on the rat thyroid toxicity test, are expected to result in adverse effects in humans. For the most common uses of DCPA, there are risks of concern for workers applying and supporting applications of DCPA, using typical equipment at the maximum application rate, even when personal protective equipment and engineering controls are used. There are specific concerns for the fetuses of pregnant individuals who apply DCPA. Based on current labels, some pregnant individuals could be subjected to exposures from 10 to 1,500 times greater than what is considered safe.

Furthermore, risks to fetuses of individuals entering areas where DCPA has already been applied (post-application workers involved in tasks such as transplanting, weeding, and harvesting) are of concern. In addition, living near areas treated with DCPA could also put the fetuses of pregnant individuals at risk. While DCPA does not appear to be widely used on turf, based on the current label directions that allow such use, there are also potential risks of concern for individuals using turf golf courses and athletic fields long after DCPA is applied. The labels currently specify that entry into treated fields must be restricted for 12 hours after application. However, for many crops and tasks, levels of DCPA in the previously treated fields remain of concern for 30 days or more.

In addition to the ORE assessment, EPA is releasing a companion document that summarizes the Agency’s findings from the thyroid toxicity data received in response to a DCPA Generic Data Call-in and explains the regulatory approach the Agency is considering to address the risks identified in the ORE assessment, in line with the Agency’s commitment to sound science and protecting human health. EPA is also publishing relevant supporting documents, including an analysis of the benefits associated with the use of DCPA. Given the breadth and severity of the potential risks identified by the Agency, the Agency’s current efforts are to determine whether effective and feasible mitigation strategies exist to fully address these risks, and barring any new information provided by public comments, the Agency is considering whether cancelation of all uses and registrations for products containing DCPA is necessary.

EPA will carefully consider public input when addressing these risks. The Agency is committed to transparency as it moves forward with regulatory action on DCPA and will keep the public advised of prospective actions in the registration review process for DCPA.

Eric Hedin

A week ago, my wife came in and announced, “There’s a scary-looking bees’ nest in the lilac bush!” Wasps routinely try to build nests around our house, so I was prepared for the worst when I went out to investigate. What I found was a basketball-sized cluster of honey bees — a “swarm.” There was no nest, only a living ball of thousands of bees hanging from a branch.

I’ve never done any beekeeping, but fortunately, we have some friends who do. We had no idea, but apparently a swarm of bees in May on an easily accessible branch is something to get excited about! Soon, our beekeeper friends rolled up in their pickup truck. One pulled on jacket and bee-proof bonnet, set a large container (a portable hive box) on top of a stepladder underneath the swarm, took hold of the branch, and shook it. The swarm of bees, all festooned together, fell in a clump into the box. Or, rather, most of them did. Hundreds of them draped over the sides, which our undaunted friend scooped into the box (with gloved hands), while hundreds more buzzed around. The couple who came kept reassuring us, “They’re not going to sting because they’re focused on staying with the queen.” I learned that the queen bee’s presence is of utmost importance for the thousands of others.

Thanks for the Bees

Our friends extended thanks for the bees, then went home, while we went inside for a belated supper. The next day, I saw a smaller swarm around a branch in the same lilac bush. Here’s the interesting thing. Our friends said that they didn’t think they had captured the queen since the bees were acting agitated, so they came right back over to recover the remaining small swarm. When they added it to the hive with the bulk of the bees, all of them settled down right away. The queen had come home.

Here was a fascinating example of a finely tuned aspect of living organisms that was surely worth further investigation. A trip to the university library and online research quickly yielded multiple sources of information about honey bees from specialists of all types. As I’ve read up on bee behavior and their life cycles, a striking picture appears of ingenious design in living systems.

A recent research article reported on the use of x-ray microscopy to provide three-dimensional, time-resolved details on how bees manufacture their iconic honeycomb structure. Several observations from the authors are worth mentioning:¹

Honeycomb is one of nature’s best engineered structures.

Engineers recognize design, and never has good human-level engineering come about by anything other than intelligent design.

Honeycomb is a structure that has both fascinated and inspired humans for millennia, including serving as inspiration for many engineering structures. It is a multifunctional structure that acts as a store for food, a nursery for developing honey bee brood, and a physical structure upon which honey bees live. It is constructed of wax produced by bees in specialized glands in their abdomen. Wax is an expensive commodity and so comb construction can be quite costly for a honey bee colony. Honeycomb is constructed in such a way to minimize wax consumption.

Honeycomb construction is optimized to serve multiple purposes for the bee colony, subject to the constraint of material and labor costs. Sounds like the bees are a responsible engineering firm.

The ability of bees to “know” how to manufacture the structurally optimal hexagonal-packed honeycomb is even more amazing when one considers that the worker bees constructing it hatched less than three weeks earlier.

While not a perfect analogy, a colony of bees may be compared to a multicellular living organism. Each member of the colony seems to know what to do at each stage of its life for the good of the whole “organism.” An isolated bee will soon die, even if supplied with nutrients, suggesting that it is designed to function as part of the whole.

Arranged by a Designer

We could say that the whole honey bee colony is greater than just the sum of its individual members. This state of affairs usually arises when the individual components of a complex system are specifically arranged by a designer to accomplish a predetermined purpose. Consider any complex electrical or mechanical device. All of the components of my laptop would make a fascinating pile if laid out on a table; but they’re even more fascinating when assembled and functioning together as a whole, according to their designed purpose.

A professor of entomology at Iowa State University, studying the behavior of honey bee colonies, writes:

Each bee appears to specialize, for a time at least, on a particular job. Thinking about this, you may decide that a single bee is somewhat like a single cell of your own body. The work force in charge of a particular job, such as feeding larvae, would then correspond to one of your tissues. And if you follow this analogy further, you may conclude that a colony of honey bees is like an organism — a superorganism.²

Aspects of an organism that manifest in a honey bee colony include caring for developing larvae, securing and processing nutrients (similar to metabolism), tending the queen (whose presence coordinates the behavior of the entire colony), guarding the hive and patrolling for intruders (similar to an immune system), temperature regulation (fanning their wings to cool the hive, clustering and vibrating their wings to heat the cluster of bees), growth of the whole colony in terms of the number of individual bees, reproduction of the “organism” (resulting in the phenomenon of the honey bee swarm), coordination of activities mediated by a variety of communication channels, and a sense of purpose.

Observers of complex, functional systems, whether nonliving or alive, rationally conclude that, “If something works, it’s not happening by accident.”³

Beyond Mere Survival

The honey bee colony “works” and accomplishes a purpose beyond mere survival. It diligently stockpiles nectar which its workers convert to honey in amounts exceeding its needs.⁴ Honey’s unique ingredients give it value as a food source for humans that has been recognized for millennia.

The high total sugar concentration [primarily fructose and glucose, with a smaller amount of sucrose] in honey is beneficial in that most yeasts cannot ferment in it. Also, together with one other constituent (glucose oxidase), it gives the honey antimicrobial properties, and it can be stored safe from spoilage…⁵

Beyond the direct production of honey for our use, the role of honeybees as pollinators is of critical importance in agriculture:

Bees and other pollinators play a critical role in our food production system. More than 100 U.S. grown crops rely on pollinators. The added revenue to crop production from pollinators is valued at $18 billion.⁶

Continuing to ponder bee behavior, comments made by Professor Richard Trump of Iowa State University are instructive:

If a honey bee, with her microbrain, knows what she is doing, this is cause for wonder. If she does not know — if she is fully programmed by those sub-microchips of DNA that come to her as a legacy from her ancestors — this is even greater cause for wonder. It is incredible.⁷

Here are a couple of examples that may cause us to wonder how bees know how to do what they do. Researchers have found that bees possess an internal organic timer, which in conjunction with an awareness of the rotation of the Earth, allows them to efficiently time their foraging activities to arrive at flowers when pollen sources are at their peak.

The famous “waggle dance” that a scout bee performs back at the hive after discovering a food source communicates to other bees (by touching, since the inside of the hive is dark) both the distance and the direction of the food in relation to the current position of the sun. Bee keepers have found that if they reorient the honeycomb on which the bee is dancing, the undaunted bee will adapt its dance so that it still correctly communicates the proper direction to the food source.⁸ Sometimes the dancing scout bee will continue its dance for more than an hour, and over this time, the position of the sun has changed. In response, the bee will compensate for the sun’s movement across the sky by gradually adjusting the angle of its dance.

How Many Lines of Code?

If humans tried to duplicate the capabilities of honey bees by building and programming mini-robots that could fly, how many lines of code would have to be written and executed to make an artificial bee? We can also ask what the likelihood is of all this coded information arising from unguided natural processes. Someone committed to the evolutionary paradigm might answer that any genomic changes that offered a survival advantage would’ve been locked in by the ratchet-like mechanism of natural selection until primitive bee ancestors evolved into the complex, coordinated colonies of honey bees seen today.

Systems engineer Steve Laufmann, co-author of the recent book Your Designed Body, addresses the engineering hurdles facing any proposed evolutionary explanation:

…when evolutionary biologists hypothesize about small and apparently straightforward changes to a species during its evolutionary history, the biologists tend to skip both the thorny engineering details of what’s necessary to make the system work, and the bigger picture of how any system change has to be integrated with all the other systems it interacts with. The result is that biologists tend to massively underestimate the complexities involved.

And here’s the rub: if they’ve massively underestimated those complexities, then they’ve massively underestimated the challenge for any gradual, materialistic evolutionary process to build up these systems a little bit at a time while maintaining coherence and function. 

1. 324-325

The difficulties outlined by Laufmann are in the context of the human body, but they apply equally well to the complexities of a colony of honey bees. Bee keepers are all too aware of the precarious balance between life and death throughout a single year for a colony of bees. Engineers know that making changes to a delicately balanced complex functional system, even small ones, have a way of upsetting the balance — not towards better function but towards failure and collapse.

Honey bees offer us a glimpse of a remarkable living system involving interdependent, communally cooperative behavior. In some ways, they outshine the best in conscious human attempts to build a thriving society.  Perhaps we can learn a thing or two from the humble bee.

Honey bees are responsible for a third of the food we consume as Americans, thanks to their ability to pollinate some of our favorite fruit, vegetables and nuts. These efforts are celebrated during Pollinator Week, which runs from June 19-25.

“Honey bees in particular are powerhouse pollinators and getting involved in protecting their habitats — down to supporting healthy ecosystems — is something we can all do not only during Pollinator Week, but year round,” says Catherine Barry, the National Honey Board’s director of marketing. “The food and beverage industry would be quite bland without honey bees, as they are responsible for pollinating many of the ingredients used in some of the biggest food brands in the world.

Here are five ways to celebrate honey bees and other pollinators, according to the National Honey Board:

1. Plant native plants: Native plants are better adapted to the local climate and soil, making them easier to grow and maintain. They also provide the best food and habitat for pollinators.
2. Plant flowers with different bloom times: Pollinators need a diverse range of flowers to meet their nutritional needs throughout the growing season. Plant a variety of flowers that bloom at different times of the year to ensure a steady supply of nectar and pollen for pollinators.
3. Create habitat: Pollinators need a place to rest and nest in between feeding. Create habitat in your garden by leaving some areas wild and adding features such as brush piles to provide shelter for pollinators.
4. Avoid using pesticides: Pesticides can be harmful to pollinators and can disrupt the natural ecosystem in your garden. Instead, use natural pest control methods such as companion planting or handpicking pests to keep your garden healthy and free of harmful chemicals.
5. Provide water: Pollinators need water to drink and to regulate their body temperature. Provide a shallow dish or birdbath filled with water to give pollinators a place to drink and cool off on hot days.
