Have you ever wondered why bees swarm? Swarming is a fascinating behavior exhibited by honeybees, where a large group of bees leaves their hive to find a new home. This captivating phenomenon occurs when a hive becomes overcrowded, and a new queen bee is born. When the new queen is ready to emerge, she emits pheromones that signal to the worker bees that it's time for a change. In response, thousands of bees venture out together on a daring journey in search of a suitable location for their new colony. Swarming is not only an incredible display of nature's ingenuity, but it also plays a crucial role in the survival and propagation of honeybees. So, let's take a closer look at why bees swarm and explore the intricacies of this remarkable behavior.

How swarming helps in genetic diversity and survival
Swarming is a natural reproductive process that enables honeybee colonies to propagate and establish new colonies. It is a way for the colony to divide itself and create multiple independent entities. Swarming typically occurs in the spring or early summer when the colony has reached a certain size and conditions are optimal for survival. The primary purpose of swarming is to ensure the continuation of the species and genetic diversity within the population.
When a bee colony swarms, the queen bee leaves the hive along with a large group of worker bees, forming the primary swarm. This primary swarm will seek out a suitable location to establish a new colony. Meanwhile, back in the original hive, the queen cells are prepared and a new queen is raised to take over the reproductive duties of the old queen. Swarming allows for the creation of new colonies with their own queen, ensuring the survival and expansion of the species.
Swarming also plays a crucial role in maintaining genetic diversity within bee populations. By dispersing and creating new colonies, it allows for the mixing of genes from the different swarms. This genetic diversity is important for the overall resilience and adaptability of the species, as it increases the chances of survival in the face of changing environmental conditions and disease pressures.
Factors Triggering Swarming
Overcrowding in the hive
Environmental cues such as temperature and availability of resources
The influence of the queen bee
Age and health of the queen bee
Swarming is triggered by a combination of internal and external factors that indicate the need for colony expansion. One of the primary triggers is overcrowding within the hive. As the colony grows in size, the available space becomes limited, and the bees instinctively respond by preparing to swarm. They sense the lack of space and start building swarm cells, which serve as special chambers for the development of new queens.
Environmental cues also play a role in triggering swarming. Temperature and resource availability are important factors that influence the bees' decision to swarm. Warmer temperatures and an abundance of nectar and pollen indicate favorable conditions for survival and reproduction, and the bees respond by initiating swarming behavior.
The queen bee has a significant influence on swarming. As she ages, her pheromone production decreases, which signals to the worker bees that it is time for swarming. Additionally, the health of the queen bee can impact swarming. If the queen is unhealthy or failing in her role as the reproductive powerhouse of the colony, the workers may decide to replace her through swarming.
Preparing for Swarming
Pre-swarming behaviors of worker bees

Queen bee preparation for swarming
Before swarming, worker bees exhibit pre-swarming behaviors as they prepare for the departure from the hive. These behaviors include increased scouting activities, where bees explore the surrounding environment in search of potential nesting sites. They also begin to gorge on honey to fuel their flight during swarming.
Worker bees start building swarm cells, which are larger and different in shape compared to regular brood cells. The construction of swarm cells typically occurs on the periphery of the brood nest, signaling the bees' intent to swarm. These specially constructed cells allow for the development and emergence of new queens.
The queen bee also undergoes preparations for swarming. She becomes slimmer and intensifies her egg-laying leading up to swarming. The increased egg-laying serves as insurance for the future of the colony. At the same time, the workers will raise new queen cells from the existing brood, ensuring a smooth transition and the continuity of the colony.
The Swarming Process

Scout bees' search for a new nesting site
During swarming, the colony divides into the prime swarm, which is led by the old queen, and potentially secondary swarms, which may contain virgin queens or additional worker bees. The prime swarm is the largest and typically contains the majority of the worker bees.
The swarming process begins with the departure of the bees from the hive. The bees gather near the hive entrance and emit pheromones to communicate their intent to swarm. The old queen leads the way, followed by a swirling mass of bees known as the swarm cluster. They fill the air with a loud buzzing sound, attracting attention and signaling their presence to nearby beekeepers or onlookers.
Once the swarm cluster is formed, it will typically settle on a nearby object, such as a tree branch or fence, while scout bees search for a suitable nesting site. The cluster of bees may hang together temporarily for a few hours or even a few days until a new home is found. During this time, scout bees communicate the location and quality of potential nesting sites through a process known as waggle dances.
Swarm Communication and Decision Making

Choosing the optimal nesting site for the swarm
Pheromones play a crucial role in swarm communication. The bees use chemical signals to relay information about their intent to swarm, the location of potential nesting sites, and the overall health and status of the colony. Pheromones emitted by the queen bee, as well as other worker bees, help coordinate and guide the swarm's behavior.
Swarm decision-making involves a collective process among the scout bees. These scout bees explore the surrounding environment in search of suitable nesting sites. When a scout bee discovers a potential site, she returns to the swarm cluster and performs a waggle dance. The waggle dance communicates the direction, distance, and quality of the site, allowing the other bees to evaluate and participate in the decision-making process. Through this collective decision-making, the swarm ultimately chooses the optimal nesting site.

Survival is crucial for the swarm cluster during the period between swarming and establishing a stable nesting site. The swarm cluster adopts a defensive posture, with guard bees protecting the cluster from potential threats. The heat generated by the worker bees within the cluster helps to maintain a stable temperature and protect the cluster from the elements.
After a suitable nesting site is chosen, the swarm moves into its temporary accommodations. This could be a hollow tree, an abandoned hive, or even a cavity in a building. The bees begin the process of building a new colony, constructing beeswax comb, and collecting resources such as nectar and pollen for nourishment.
In the absence of a queen, a new queen bee needs to be selected and accepted by the swarm. Worker bees will select a few potential queen candidates and feed them royal jelly, a special jelly-like substance produced by the worker bees. The candidate who is properly nourished with royal jelly will develop into a new queen, ensuring the reproductive capabilities of the colony and the establishment of a new generation.
Impact of Swarming on the Parent Colony
Reduction in population and workforce
The need for replacement queens
Recovery and rebuilding of the parent colony
Swarming has a significant impact on the parent colony left behind after the prime swarm departs. The swarming process results in a reduction in population and workforce. The majority of the worker bees leave with the prime swarm, leaving a smaller number of bees to perform the necessary tasks within the hive. This decrease in workforce can temporarily affect the efficiency and productivity of the parent colony.
Swarming also necessitates the need for replacement queens in the parent colony. With the departure of the old queen, a new queen needs to be raised and mated to ensure the colony's survival and regeneration. The worker bees continue to raise new queen cells and feed developing larvae with royal jelly to ensure the emergence of new queens.
The parent colony goes through a process of recovery and rebuilding after swarming. The remaining worker bees must reorganize themselves to resume their roles and responsibilities within the hive. With the emergence of new queens, the colony can regain stability and continue its reproductive and survival functions.
Beekeeper Management of Swarming
Preventive measures to reduce swarming
Swarm control techniques for beekeepers
Capturing and relocating swarms
Beekeepers play an important role in managing and mitigating the potential issues related to swarming. They employ preventive measures to reduce the likelihood of swarming in their hives. This involves providing sufficient hive space for the growing colony, regular monitoring of population size, and management techniques to prevent overcrowding.
When swarming does occur, beekeepers employ swarm control techniques to prevent the loss of valuable bees and minimize disturbance to neighboring areas. These techniques include removing queen cells, dividing the colony, or creating an artificial swarm to guide the bees into a new hive. By actively managing the swarming process, beekeepers can maintain the health and productivity of their colonies.
Beekeepers also have the option of capturing and relocating swarms. When a swarm is discovered, beekeepers can carefully collect the bees and transfer them to a new hive. This allows the beekeeper to benefit from the increased bee population and establishes a new colony that can contribute to pollination and honey production.
