Waggle wars: Honeybees’ dance moves boost food hunts for the hive — Study



Fascinating and mesmerizing, honey bees talk to one another by dancing, but it doesn’t always work, according to a new study from Virginia Tech.

Known as the “waggle” dance, the duration and direction of their buzzy routine convey “foraging instructions” to their fellow bees as to where to go and how far it is. They pass on information to one another in a jubilee. It is their excitement that inspires their nestmates to leave the nest.

According to Virginia Tech, honeybees don’t always reach their intended destination, prompting entomology researchers to investigate why their waggle dances sometimes fail.

“Although the waggle dance itself is fascinating, my lab has additionally been intrigued about waggle dance miscommunication or the hows and whys behind the failure of the dance recruitment,” Couvillon said.

Each bee has its own “style” of dancing

Head researcher Margaret Couvillon and her team at Virginia Tech observed the intricacies of the dances. Each bee seems to put its own special spin on the idea, so each dance is somewhat unique.

The Couvillon Lab designed an experiment to watch and track them foraging and dancing. They predicted bees with similar dances or communication styles would more likely reach their desired destination: food.

During the experiment, researchers fed foragers the food’s location. They would subsequently dance from their sheer joy. Zeroing on this pattern, they were able to observe under which conditions the communication strategy worked.

However, once they gathered the data from the experiment, researchers were surprised by the findings, which shed light on what defines a successful honeybee dance.

Being uniquely themselves

Researchers were surprised to discover that a similar dancing language didn’t necessarily result in a successful food run and that the individual variations actually amplified the chances of finding the prize.

Bees that provided highly precise distance instructions often struggled to guide their nestmates successfully, according to a press release. However, those that slightly “overshot” the distance improved the chances of recruits locating the food source.

As head researcher Couvillon concluded, honeybees have a remarkable individuality, and their beautiful, enthusiastic dance only fits the character of the Earth’s most beloved pollinator with an intriguing society.

US lost 55% of its honeybee populations

In light of the diminishing number of honeybees, a computer science team from UC Riverside has developed the technology to improve beehive health in commercial settings.

“Over the last year, the U.S. lost over 55% of its honeybee colonies,” Boris Baer, UCR professor of entomology, told UC Riverside News.

“We are experiencing a major collapse of bee populations, and that is extremely worrying because about one-third of what we eat depends on bees.”

Along with the sensor from UC Riverside that se to support beekeeping, bolstering a form of communication that aids the bees in their survival might increase their chances.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

  Non-contact exposure to dinotefuran disrupts honey bee homing by altering  MagR  and  Cry2  gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering  MagR  expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the  MagR  gene responded to magnetic fields only in the presence of light, with  Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

Bee attack claims life of newspaper distributor

  Bee attack claims life of newspaper distributor Newspaper distributor Pushparaja Shetty (45), who sustained severe injuries in a bee attack, succumbed to his injuries on Thursday at a hospital in Mangaluru. Pushparaja was attacked by a swarm of bees on Wednesday morning while walking at Kenjaru Taangadi under Bajpe town panchayat limits. He was immediately admitted to a hospital for treatment but could not survive the ordeal. Fondly known as ‘Boggu’ in the Porkodi area, Pushparaja was well-known for his dedication to delivering newspapers on foot to every household. He was admired for his generosity, as he often distributed sweets to schoolchildren on Independence Day using his own earnings and contributed part of his income to the betterment of society. Pushparaja was unmarried and is survived by three brothers and one sister.

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

  “Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups.  Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

Start the New Year Humming Like a Bee

  Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The Essential Role of Bees in Our Ecosystem and the Challenges They Face

The Essential Role of Bees in Our Ecosystem and the Challenges They Face Bees have been an integral part of our ecosystem and human agriculture for over four centuries, primarily utilized for their honey in the early days. Now, they are recognized more for their critical role in pollination, which directly impacts a vast majority of the food we consume. Mark Lilly, a prominent beekeeper, emphasizes that without bees' pollination efforts, a significant portion of our diet would be at risk. However, bees face numerous threats, including varroa mites and, in specific regions like West Virginia, black bears. These challenges necessitate concerted efforts for preservation and protection. Frequently Asked Questions (FAQs) Q1: Why are bees so important to the ecosystem? A1: Bees are crucial for pollinating plants, which is necessary for the production of fruits, vegetables, and nuts. Without bees, a large portion of the food we eat would not be available. Q2: What are the main threats to...

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles As the number of pets in South Korea steadily increases, pet owners face a growing dilemma due to the limited number of pet cemeteries across the country. Under the current legal framework, pet remains are classified as household waste, requiring specific disposal methods that are neither convenient nor easily accessible for all citizens. The imbalance between the rising pet population—over 5.52 million households with pets by the end of 2022—and the mere 70 registered pet cemeteries has led to significant challenges. This shortage is particularly evident in regions like Jeju Island, where pet owners must undergo arduous journeys to the mainland to ensure their pets receive proper burials. The root cause of this shortage lies in the strict regulations governing the establishment of pet cemeteries. These facilities, which must include crematoriums, face numerous restrictions, such as proximity to resident...

Climate Crisis Claims Glacier's Vital Climate Data Archive

  Climate Crisis Claims Glacier's Vital Climate Data Archive A recent study published in Nature Geoscience reveals a distressing consequence of global warming: the irreversible loss of valuable climate data stored in alpine glaciers. The research, conducted by a team led by Margit Schwikowski from the Paul Scherrer Institute (PSI), underscores the alarming rate at which glaciers are melting and highlights the implications for climate research. The study focuses on the Corbassière glacier at Grand Combin in Switzerland, where ice cores drilled in 2018 and 2020 were intended to serve as vital climate archives. However, comparing the two sets of ice cores reveals a grim reality—global warming has rendered the glacier unsuitable as a reliable climate archive. Glaciers, renowned as climate archives, encapsulate valuable information about past climatic conditions and atmospheric compositions. The fluctuating concentrations of trace substances in ice layers provide insights into historica...

German election: Climate and environment take a back seat

  German election: Climate and environment take a back seat When the coalition government comprising the center-left  Social Democratic Party (SPD) ,  Greens  and neoliberal  Free Democratic Party (FDP)  emerged after the last German federal election in the fall of 2021, then-incoming Chancellor  Olaf Scholz  (SPD) did not object to being called the "climate chancellor." That was no surprise: the climate crisis had been a top issue during the election campaign. The new government made the fight against climate change a task for the Economy Ministry and appointed Vice Chancellor  Robert Habeck  from the Greens as its head. Three and a half years later, campaign speeches barely mention climate protection. The dominant issues are how to curb irregular immigration and how to boost Germany's sluggish economy. Skeptical view of renewable energy The head of the center-right  Christian Democratic Union (CDU) ,  Friedrich Merz ...
