Discover How Bees Communicate With Each Other!

As one of the few insect species to capture the attention of researchers worldwide, bees exhibit impressive communication abilities. Similar to industrial production processes, these natural pollinators require a harmonious environment to optimize their efficiency and survival. Effective communication is one of the keys to these insects' success for better colony organization in every task. Excellent coordination of actions and behaviors is vital for these insects.

How Do They Organize Themselves?

Bees are renowned for being a highly organized natural mini-production machine. These insects naturally live in a colony within a hive. A bee colony is represented by its queen, worker bees, and drones. Each has a role to play in ensuring the cohesion and survival of the colony. Everything runs smoothly thanks to a highly developed communication system.

The Main Responsibilities of the Queen Bee

A hive must be led by a queen. The queen alone ensures the perpetuation of the bee lineage, whether purebred or hybrid. To do this, she can lay an average of nearly 2,500 eggs per day. For reproduction, she performs a type of dance, including the nuptial flight, according to their communication method. She calls upon the males of the colony to provide her with spermatozoa. She stores and fertilizes her eggs to lay them in each cell. Indeed, fertilized eggs will result in female bees, and unfertilized ones will become drones or male bees.

A queen's characteristic traits are recognized by her physical appearance. Naturally, she is unique in her body size. Her abdomen is more developed than those of other bees in the same hive. At the larval stage, the queen feeds exclusively on royal jelly to distinguish herself from the others.

As for the queen's functions, she holds the primary leadership role in her colony. She communicates with the rest of the hive members to maintain good cohesion within the family. To do this, she produces ample pheromones to ensure this task.

Multitasking: The Class of Worker Bees and Their Respective Roles

These are infertile female bees. In a hive, worker bees are the versatile laborers of the colony. They perform almost all tasks: collecting and storing food, cleaning the hive, and guarding it. Moreover, they feed on pollen throughout their short lives.

Worker bees are responsible for the pantry and cleanliness of the bee hive. They share their tasks efficiently under the queen's leadership. Forager bees are those who search for pollen, water, nectar, and propolis. Storage bees ensure their food is well-organized and stored in the hive. For wax and royal jelly producers, these are wax-producing bees and nurse bees. The cleaning responsibilities fall to the cleaner bees. They clean the hive and also tend to their queen. Guard bees are primarily responsible for the hive's security.

Male Bees or Drones: Born Reproducers

These are the bees that reproduce with the queen. Just after reaching maturity, drones gather in an unspecified area to facilitate the queen's detection. Here again, communication is very important for these insects. The males fly, performing gestures to show the queen their willingness to reproduce. This process can occur in mid-flight between a queen and a succession of about fifteen male bees on average. Once the males have successfully released their spermatozoa, they lose their reproductive organs and succumb to death.

How Does Bee Communication Work?

Bees possess three natural communication tools to work with good cohesion and coordinate their living environment. Everything depends on the communication channel: mating, food foraging, hive and queen maintenance, and guarding duties. The queen always remains the conductor.

However, worker bees and drones also possess these abilities, including:

• The Olfactory Communication System of Bees or Pheromones

Almost all insects are endowed with this olfactory ability through pheromones. This is a chemical substance secreted by these animals. For bees, this phenomenon manifests at the antennae. They possess highly developed antennae compared to other insect species.

Pheromones in bees are activated by the Nasanov gland. This gland is primarily located on the dorsal part of these natural pollinators' abdomen. These glands play crucial roles in bee movement and their biological evolution.

At least 4 types of pheromones are distinguished in bees, which activate according to the situation they face:

Queen pheromones or royal pheromones. Only the queen has the ability to use this type of substance. They are intended to maintain harmony in a bee colony. The queen's mandibular pheromones are dispersed throughout the hive to inhibit other bees. This is swarming. It involves preventing the creation of other royal cells. And they also render worker bees sterile. Everything is done simply through food exchange.

Sexual or reproductive pheromones. It is through this language that queens communicate their fertility to males or drones.

Alarm pheromones. This is a means of communication that is naturally triggered in case of a hive attack. They communicate to alert the colony. This results in the organization of the escape of foraging bees responsible for food. It is also the same language for calling novice workers or lost bees back to order.

Territory marking pheromones. This constitutes an instinctive boundary for a colony's living environment. It is essential for each colony to respect this type of commitment for their safety and survival.

• Antennal Communication by Contact

This type of communication generally occurs during food exchanges between foraging bees and storage bees. This is trophallaxis. Practically, these workers touch each other at the mandibles to convey the message. Foragers who go in search of food, such as nectar or pollen, store it in their honey stomachs. Then, other bees take the food to store it in the hive. At the end of the transfer, antennal contact occurs to complete the task.

• Communication Through Dance

Very impressively, bees are capable of performing a kind of choreography to communicate. This communication system is often observed during food foraging. It concerns the forager bees. Specifically, they share their findings with their counterparts. They buzz and beat their wings, performing dances typical of bees. The movement of the foragers depends somewhat on the type of nectar found: its location, the smell of the nectar, whether it's close to their hive or in a distant area. All these gestures are often accompanied by contact at the mandibles. These bees also bring nectar samples to show the colony.

It's worth noting that recent studies by researchers have provided a more precise understanding of bee language through their movements. If foraging bees perform round dances, it indicates a very close nectar source. However, if it is located a bit far from the hive, they perform waggle dances.

For some observers, bees use more concrete signals during communication. Regarding distance, bees vibrate their bodies according to the remoteness. 750 m of distance is equivalent to one second of vibration, and so on. Among other things, bees also direct other foragers to the exact location of the nectar. To do this, they move their abdomen while performing gestures corresponding to the angle of direction. They can also provide ample information on the quantity of food found at the site. The more abundant the nectar, the more bees perform rotational movements while repeating the same dances.

In summary, bees are highly organized insects in harmonizing their colony life. Their natural instincts facilitate this group cohesion. It is important to be aware of the significance of these insects in biodiversity and the ecosystem. They are responsible for more than three-quarters of global plant pollination. Therefore, it is crucial to safeguard all bee species worldwide to ensure human survival.
