Bee Communication During Swarming:The Science Behind Swarming

Swarming is a phenomenon that usually occurs in spring and early summer. As the bee colony grows and the hive becomes overcrowded, it triggers the need to find a new home. This is nature’s way of ensuring the survival and propagation of the bee species.

The Waggle Dance: Nature’s GPS

One of the most fascinating aspects of bee communication during swarming is the waggle dance. This dance is a method used by scout bees to communicate the location of potential new nesting sites to the rest of the swarm. The direction and duration of the dance provide specific information about the direction and distance of the new site.

For instance, a bee that waggles in a straight line towards the sun indicates a food source in that direction. The duration of the waggle indicates the distance. A longer waggle means the source is farther away.

Other Communication Techniques

Apart from the waggle dance, bees use other methods to communicate during swarming:

• Pheromones: These are chemical signals released by bees, especially the queen, to coordinate the swarm’s movement. The queen releases specific pheromones to attract worker bees and keep the swarm cohesive.
• Buzzing Sounds: Bees produce specific buzzing sounds during swarming, which can signal different things, such as the readiness to move or the presence of danger.

The Role of Scout Bees

Scout bees play a crucial role during swarming. They are responsible for finding a new nesting site. Once they identify a potential site, they return to the swarm and communicate the location using the waggle dance. The decision to move to the new site is usually a consensus, with multiple scout bees performing the dance and the swarm choosing the most popular site.

Challenges and Threats

While swarming is a natural process, it comes with its set of challenges. Predators, adverse weather conditions, and human interventions can pose threats to the swarm. Effective communication is crucial to navigate these challenges and ensure the swarm’s survival.

Advanced Research on Bee Communication

Recent studies have shed light on the intricate communication methods bees employ, especially during swarming. These findings not only enhance our understanding of bee behavior but also have implications for various fields, from robotics to conservation.

Social Learning and Cultural Transmission

While individual bees might seem insignificant, a colony as a whole exhibits complex behaviors. Researchers have been intrigued by how bees communicate and share knowledge for years. A groundbreaking study in PLOS Biology demonstrated that bees are capable of social learning and cultural transmission. In this experiment, bees were trained to pull a string to obtain a sugar reward. These trained bees could then teach this skill to their colony-mates. The behavior persisted even after the trained bee was removed, indicating that bees can learn by observing others. This ability to acquire and spread a skill within the colony signifies a cultural element in bee societies.

Bee Learning in Natural and Unnatural Settings

Bees can be trained for various tasks. Another study in PLOS ONE introduced an operant conditioning test where bees pushed a cap to reveal a food source. In more natural settings, the Asian honey bee species, Apis cerana, often faces threats from hornets. When exposed to predator odors or alarm pheromones, these bees struggled to associate a stimulus with a sugar reward, highlighting the impact of external threats on bee learning.

Warning Mechanisms and Threat Communication

Bees have evolved multiple mechanisms to alert their colony of impending dangers. The Asian honey bee, Apis cerana, can not only warn its nest-mates of a threat but can also convey the severity of the threat. They employ a ‘stop signal’ – a brief vibrational pulse that communicates the nature and magnitude of the danger. Depending on the signal, bees might avoid a food source, stay within the nest, or even attack an intruder.

Bee Communication During Swarming:The Complexity of Intra-Colony Communication

Communication within bee colonies is multifaceted. Apart from the renowned “waggle dance,” bees engage in various collective behaviors. For instance, the Asian giant honeybee, Apis dorsata, uses collective respiratory behavior to ventilate their hives, ensuring optimal temperature and air quality. However, these collective behaviors can sometimes be exploited. The Cape bee, a subspecies of the Western honeybee, can invade other colonies, utilize their resources, and lay its eggs, which develop into worker bees capable of asexual reproduction.

Flight and Information Processing

Another dimension of bee research focuses on their flight patterns and information processing during flight. By training and observing free-flying bees, researchers found that bees recognize objects based on their three-dimensional shapes. They employ specific flight maneuvers to derive depth cues, suggesting an optimized strategy for gathering visual information.

Pathogens and Their Impact on Bee Behavior

Pathogens pose significant threats to bees, affecting their behavior and overall health. Research has shown that bees infected with the fungal pathogen Nosema apis alter their flight patterns, indicating a balance between foraging activities and immune response. Despite the physiological effects of pathogen infections, bees maintain their optimal search strategies, showcasing their resilience.

Frequently Asked Questions (FAQs)

1. What is a Swarm of Honey Bees?

Swarming is the process by which honey bee colonies reproduce to form new colonies. When a honey bee colony becomes too congested or populated, the workers signal the need to swarm. The workers begin building swarm cells for new queens, and once these cells are constructed, the colony’s behavior changes. The queen quits laying eggs, reduces her weight, and when ready, leaves the hive followed by about half of the workers. The queen finds a nearby tree, lands, and emits pheromones that signal the workers to cluster around her. This cluster remains until scout bees locate a new hive or cavity to occupy.

2. When Do Swarms Occur?

Swarming activity usually coincides with the nectar flow in the spring, primarily between March and May. This is when a wide variety of plants are in bloom, providing abundant nectar and pollen resources. Occasionally, secondary swarms might occur later in the season, but they often face challenges in establishing new colonies.

3. Are Swarms Dangerous?

While swarming, honey bees are not as defensive as they are around their hive since they aren’t protecting brood or honey stores. They are more focused on scouting for a new home and clustering around the queen. However, if disturbed or agitated, they will defend the cluster. It’s advisable to keep a distance from a bee swarm to avoid being stung.

4. How Long Will a Swarm Stay in One Place?

Typically, swarms stay in one place for a few hours or maybe a day. However, depending on weather conditions and when scout bees find a suitable cavity, some swarms may remain for several days.

5. How Can a Problematic Swarm Be Safely Removed?

If a swarm is in a problematic location, it’s essential not to spray it with insecticides or attempt to destroy it. Instead, contact a local beekeeping association to safely remove the swarm. Beekeepers are often eager to collect swarms to start new colonies. A list of local beekeeper associations can be found here.

6. What Happens If Bees Move Into a Building?

If bees move into a building structure, they will remain to build a new colony. They will construct wax combs, lay eggs, and store honey and pollen. Sealing the entrance or killing the colony without removing it can lead to rotting bees and hive materials, attracting pests. The colony and its provisions must be removed before sealing the entrance.

7. Is It Illegal to Destroy a Honey Bee Swarm?

While it’s not illegal to destroy a honey bee swarm, it’s not advisable. Honey bees are beneficial pollinators supporting agriculture and native plant communities. Instead of destroying them, it’s better to contact a local beekeeper’s association for safe removal.

8. Why is Beekeeping Growing in South Carolina?

Beekeeping is growing in South Carolina due to the state’s developing areas. This growth indicates that South Carolina’s beekeeping trade is vibrant, and beekeepers are overcoming various challenges they face.
