Bees are absolutely crucial to the health and vitality of our ecosystem. However, many people do not realize the intricate and complex anatomy of these small but mighty creatures. In this article, I will discuss the basics when it comes to understanding bee anatomy, including the different body parts and functions of a bee. Understanding bee anatomy is essential for beekeepers and anyone interested in the vital role that bees play in our environment.
External Anatomy of a Bee
The external anatomy of a bee is made up of three main parts: the head, thorax, and abdomen. The head contains the bee’s sensory organs while the thorax houses the bee’s wings and legs. The abdomen is where the bee’s internal organs are located, such as the digestive and reproductive systems.
The Structures of a Bee’s Head
The head of a bee is a marvel of natural engineering, housing several critical components that allow these fascinating insects to function effectively in their environment. Among the key features of a bee’s head are the compound eyes, simple eyes (ocelli), antennae, and various mouthparts. Each of these structures plays a vital role in the bee’s ability to navigate, communicate, and forage for food.
Compound Eyes: Panoramic Vision
A bee’s compound eyes are comprised of numerous individual units called ommatidia. These tiny lenses work together to provide the bee with a broad, almost panoramic view of their surroundings. This visual ability allows bees to detect movement, perceive color (including ultraviolet), and navigate with remarkable precision. Bees rely on this keen sense of sight to find flowers, communicate with other bees, and avoid potential predators.
Simple Eyes (Ocelli): Navigating with Light
In addition to their compound eyes, bees possess three simple eyes, or ocelli, located on the top of their head. These light-sensitive structures are critical for the bee’s ability to maintain orientation and navigate using the sun’s position. Ocelli are particularly important for honeybees as they rely on the sun’s location to communicate the direction and distance of food sources through a complex “waggle dance.”
Antennae: Sensitive Sensory Organs
The antennae of a bee are its primary sensory organs, providing vital information about their environment. Each antenna is covered in a multitude of sensory receptors that can detect various chemicals, air movement, and temperature changes. These receptors allow bees to locate food sources, communicate with their hive-mates, and recognize changes in weather conditions that might affect their foraging activities.
Mouthparts: Collecting and Processing Nectar and Pollen
A bee’s mouthparts are specialized for collecting and processing nectar and pollen from flowers. The mandibles, or jaws, are used for chewing and manipulating food as well as for other tasks such as grooming and building honeycomb. The proboscis, or tongue, is a tubular structure that can extend to reach nectar within flowers. Bees use their tongues to suck up nectar and mix it with enzymes in their mouth before transferring it to their honey stomach. As bees forage for nectar, their bodies collect pollen, which is then transferred to specialized pollen baskets on their hind legs for transport back to the hive.
The Structure of a Bee’s Thorax
The thorax is the central section of a bee’s body, positioned between the head and the abdomen. It is an essential part of the bee’s anatomy as it houses the mechanisms for locomotion and respiration.
Wings and Flight
Bees possess two pairs of wings, with the forewings being larger than the hindwings. These wings are connected to the thorax by a complex set of muscles, which provide the necessary force for the bee to fly and maintain stability in the air. The bee’s wings are highly specialized and are capable of beating at incredible speeds, up to 200 times per second, allowing for remarkable agility and swift movement. Moreover, the bee’s wings can be folded back over their body when not in use, minimizing damage and conserving energy.
Legs and Their Multiple Functions
Attached to the thorax are the bee’s three pairs of legs, each having a specific function. The front legs are primarily used for cleaning the antennae, which are essential sensory organs for bees. The middle legs serve multiple purposes, such as walking, grooming, and assisting with the collection of pollen. The hind legs, on the other hand, are specially adapted for pollen collection and storage. Equipped with stiff hairs called scopa and a specialized structure called the pollen basket (or corbicula), the hind legs allow the bee to transport pollen back to the hive efficiently.
Spiracles and Respiration
Respiration in bees occurs through a network of small openings on the thorax and abdomen called spiracles. These spiracles are connected to an intricate system of air tubes called tracheae, which deliver oxygen to the bee’s tissues and remove carbon dioxide. Bees have the ability to control the opening and closing of their spiracles, thereby regulating their oxygen intake and preventing water loss. This respiratory system is vital for the bee’s survival as it enables them to maintain their high levels of energy and activity.
The Abdomen of a Bee: Exploring its Structure and Importance
The abdomen of a bee plays a crucial role in the overall functioning of these fascinating insects. It is a complex structure composed of several segments, which house many of the bee’s vital internal organs. In this section, I will delve deeper into the various components of a bee’s abdomen, exploring its digestive, circulatory, and reproductive systems, as well as the essential wax glands and the formidable stinger.
Digestive System: Fueling the Bee’s Activities
The digestive system in a bee’s abdomen is responsible for breaking down food and extracting nutrients, which are essential for the bee’s survival and productivity. The process begins with the ingestion of nectar or pollen, which enters the bee’s mouth and travels through the esophagus to the crop, also known as the honey stomach. The crop stores the nectar for transport back to the hive while enzymes begin the initial process of breaking down the nectar into simpler sugars.
After returning to the hive, the bee regurgitates the nectar for processing by other bees, who further break it down into honey. The bee’s actual stomach, or ventriculus, digests pollen, which provides proteins and other nutrients necessary for the bee’s growth and development.
Circulatory System: Pumping Life Through the Bee
The circulatory system in a bee’s abdomen is an open system, which means that the bee’s blood (called hemolymph), is not enclosed within blood vessels. Instead, it freely bathes the internal organs in the abdomen. The bee’s tubular heart runs along the length of the abdomen, pumping hemolymph through the aorta and dispersing it throughout the body. The hemolymph then flows back to the heart through small openings called ostia, completing the circulation process.
Reproductive System: The Key to Colony Survival
The reproductive organs of a bee are found within the abdomen, and their structure and function differ significantly between the three castes of bees: queens, drones, and workers.
- Queens: The queen bee’s primary role in the colony is reproduction. She possesses a large, well-developed spermatheca, which stores sperm collected during her mating flights. The queen can lay both fertilized and unfertilized eggs, giving rise to either worker bees (females) or drones (males), respectively.
- Drones: Drones have only one function: to mate with the queen. Their reproductive organs are adapted for this purpose, with the endophallus designed for transferring sperm to the queen during mating flights.
- Workers: Worker bees typically have undeveloped reproductive systems as they do not reproduce. In some cases though workers can lay unfertilized eggs that give rise to drones, but this is a relatively rare occurrence.
Wax Glands: Building the Bee’s Home
Located on the underside of the abdomen, wax glands are specialized structures that produce beeswax. Worker bees secrete wax in the form of small flakes, which they then manipulate with their mouthparts to build honeycomb structures for storing honey, pollen, and brood. The production of beeswax is temperature-dependent, with the ideal temperature for wax secretion being around 33-36°C (91-97°F).
The Stinger: Defense and Sacrifice
The stinger, or ovipositor, is a modified egg-laying organ found at the tip of the abdomen in female bees (queens and workers). It is primarily used for self-defense and to protect the hive from potential threats. The stinger is equipped with a venom gland that injects a potent cocktail of toxins into the target, causing pain and, in some cases, triggering allergic reactions. The stinger of a worker bee is barbed, which means that once it penetrates the skin of a mammal, it becomes lodged and cannot be easily removed. When the worker bee attempts to fly away, the stinger is ripped from its abdomen, causing the bee to die shortly after. Queen bees, on the other hand, possess a smooth stinger that allows them to sting multiple times without the risk of losing their stinger.
Internal Anatomy of a Bee
The internal anatomy of a bee is just as intricate as its external anatomy. Bees have several essential systems, including the digestive, circulatory, respiratory, nervous, and reproductive systems.
Digestive System of a Bee: Efficient and Specialized for Nectar and Pollen Processing
The digestive system of a bee is a marvel of nature, specifically designed to process nectar and pollen, which are the primary food sources for these industrious insects. In this intricate system, different organs play essential roles in the digestion and absorption of nutrients necessary for the bee’s survival and honey production.
The Journey of Nectar and Pollen through the Bee’s Digestive System
1. Ingestion and Storage: The Crop (Honey Stomach)
The bee’s digestive journey starts when they collect nectar and pollen from flowers using their proboscis. The ingested nectar is temporarily stored in a specialized organ called the crop or honey stomach. This sac-like structure can expand to store large amounts of nectar, which the bee will later regurgitate and process into honey back at the hive. Pollen, on the other hand, is stored in the bee’s pollen basket, located on their hind legs.
2. Filtration: The Proventriculus
When it’s time for the bee to digest its meal, the nectar from the crop or honey stomach moves into the proventriculus. The proventriculus is a narrow, valve-like structure that acts as a filter, preventing large particles from entering the next organ in the digestive system. It also secretes enzymes that begin breaking down the nectar into simpler components.
3. Digestion and Absorption: The Ventriculus (Midgut)
The main site of digestion and nutrient absorption in a bee is the ventriculus or midgut. As the nectar passes through the proventriculus, it enters the ventriculus, which contains digestive enzymes that break down the nectar into simpler components like glucose and fructose. The bee’s body absorbs these nutrients, along with essential amino acids from the ingested pollen to fuel its daily activities, growth, and reproduction. The ventriculus also houses beneficial microorganisms that help break down and ferment the pollen, making it easier for the bee to extract essential nutrients.
4. Excretion: The Malpighian Tubules and Hindgut
Once digestion and absorption are complete, the remaining waste products need to be eliminated from the bee’s body. The Malpighian tubules, which are connected to the ventriculus, filter waste products from the hemolymph (bee’s circulatory fluid, equivalent of blood) and transport them to the hindgut. The hindgut, comprising the ileum and rectum, compacts the waste and eventually expels it from the bee’s body through the anus.
The Circulatory System of a Bee: Understanding the Role it Plays in the Bee’s Life
The circulatory system of a bee is a vital component in its overall functioning and survival. Unlike humans and other vertebrates, bees have an open circulatory system. This type of system, found in many invertebrates, is characterized by the free circulation of hemolymph within the body cavity, known as the hemocoel.
Hemolymph: The Lifeblood of Bees
Hemolymph serves several important functions. It not only transports essential nutrients and oxygen to various tissues and organs, but it also aids in the removal of metabolic waste products from the bee’s body. Additionally, hemolymph plays a critical role in the bee’s immune response as it contains specialized cells called hemocytes that help combat infections and other foreign invaders.
The Heart: The Pump Driving the Circulatory System
At the center of a bee’s circulatory system is its tubular heart, which runs along the length of the dorsal side of the body. This elongated, segmented organ pumps hemolymph through a series of valves called ostia, which allow the fluid to flow in one direction, from the posterior to the anterior end of the bee. As the hemolymph is pumped through the body, it bathes the organs and tissues in the nutrients and oxygen they need to function.
Respiratory System: Delivering Oxygen to the Hemolymph
In order to provide the hemolymph with the oxygen it requires, bees rely on a separate respiratory system consisting of tiny, branching tubes called tracheae. These tubes penetrate throughout the bee’s body, allowing oxygen to directly diffuse into the hemolymph and carbon dioxide to be expelled. This diffusion-based respiratory system is essential for the efficient functioning of the bee’s open circulatory system.
Circulation and Temperature Regulation
Another key role of the bee’s circulatory system is temperature regulation. As ectothermic animals, bees rely on external sources to regulate their body temperature. When a bee is too cold, it can use its flight muscles to generate heat, which is then distributed throughout the body by the hemolymph. Conversely, when a bee is too warm, it can cool down by circulating the hemolymph more rapidly and exchanging heat with the environment.
Respiratory System: A Detailed Look at the Unique Breathing Mechanism in Honeybees
The respiratory system of a bee is a fascinating and intricate part of its anatomy, designed for efficient gas exchange to supply the bee’s high energy demands. Unlike mammals, which possess lungs, bees have a tracheal system for respiration. This section will delve into the various components of a bee’s respiratory system, from spiracles to tracheae, and the role each component plays in supporting the life of these vital pollinators.
Spiracles: The Entry Points for Air
Bees, like other insects, have a series of small openings called spiracles, located along the sides of their thorax and abdomen. In honeybees, for instance, there are ten pairs of spiracles: two pairs on the thorax and eight pairs on the abdomen. These spiracles serve as entry and exit points for air, allowing oxygen to flow in and carbon dioxide to be released. The spiracles can open and close, regulated by muscular and nervous control, to prevent water loss and maintain the internal environment.
Tracheae and Tracheoles: A Network of Tubes for Gas Exchange
The spiracles are connected to a network of tiny, branching tubes called tracheae, which further subdivide into even smaller tubes called tracheoles. These tracheae and tracheoles are lined with a thin layer of cuticle and filled with air. The tracheoles penetrate the bee’s tissues and cells, facilitating the direct diffusion of oxygen into the cells and the removal of carbon dioxide.
The tracheal system is highly efficient at delivering oxygen directly to the cells where it is needed, and it also provides structural support to the bee’s body. The flexibility of the tracheal tubes allows the bee to move and maintain its agility while in flight.
Circulatory System and Respiratory System Interactions
While the circulatory system in bees does not play a direct role in gas exchange like it does in mammals, it still interacts with the respiratory system. Hemolymph circulates through the bee’s body and transports nutrients, hormones, and waste products. The respiratory system and the circulatory system work together to maintain the bee’s overall health and vitality.
Bee Respiratory Adaptations
Bees have evolved certain adaptations to improve their respiratory efficiency, such as the ability to regulate their spiracle openings and closing to prevent dehydration. They also have the capacity to increase their metabolic rate during flight or foraging by opening their spiracles wide and increasing the flow of oxygen into their tracheal system.
Additionally, bees are capable of temporarily reducing their oxygen consumption in low-oxygen environments, such as when they are trapped in water, by entering a state of reduced metabolic activity.
The Complex Nervous System of a Bee: Sensory Processing and Movement Control
The nervous system of a bee, though small in size, is remarkably complex and efficient. It enables the bee to process sensory information, communicate with other bees, and carry out intricate movements necessary for survival. The bee’s nervous system is composed of several key components, including a brain, ganglia, and sensory organs, all working in harmony to enable a range of behaviors and functions.
The Bee’s Brain: Center of Cognitive Function
The bee’s brain, or supraesophageal ganglion, is the central hub of cognitive function. It processes sensory input from various sources, such as the antennae, eyes, and other organs. The brain is responsible for interpreting and integrating this information, allowing the bee to navigate its environment, recognize and remember locations, and make decisions.
Ganglia: Coordination of Movement and Behavior
The bee’s nervous system also consists of a series of interconnected ganglia – clusters of nerve cells that serve as mini-brains distributed along the length of the bee’s body. These ganglia play a crucial role in controlling and coordinating the bee’s movement, reflexes, and complex behaviors, such as foraging and grooming.
Sensory Organs: Gathering Information from the Environment
Bees possess an array of sensory organs that enable them to gather information about their surroundings. While all discussed in the above paragraphs in more detail , in summary these are:
- Compound Eyes – Bees have two large compound eyes, each consisting of thousands of individual units called ommatidia. These eyes allow the bee to perceive color, light intensity, and movement, helping it to navigate and locate flowers for foraging.
- Ocelli – In addition to compound eyes, bees have three simple eyes called ocelli situated on the top of their head. These eyes detect light intensity and help the bee maintain its orientation during flight.
- Antennae – Bees have two antennae that serve as multifunctional sensory organs, detecting touch, smell, taste, air currents, and even vibrations. The antennae are crucial for communication between bees, particularly in the dark confines of the hive.
- Tarsi – Bees have specialized taste receptors on their feet, known as tarsi, which enable them to taste the surfaces they walk on. This helps them to assess the quality of nectar and pollen on flowers.
Integration and Communication
The bee’s nervous system integrates the sensory input from various sources, allowing it to make informed decisions and respond to its environment. This sophisticated system also enables communication between bees through the famous “waggle dance,” which relays information about the location of food sources and other relevant details to other bees in the hive.
The Intricate Reproductive System of Bees: From Mating to Egg-Laying
The reproductive system of a bee is a highly specialized and efficient mechanism that plays a vital role in the survival and growth of the hive. It revolves around three key members of the colony: the queen bee, the drones, and the worker bees. Each of these bee types serves a unique and crucial purpose in the hive’s reproductive cycle.
The Queen Bee: A Hive’s Egg-Laying Machine
The queen bee is the most important member of a bee colony in terms of reproduction. She is the only sexually mature female in the hive and her primary function is to lay eggs. The queen bee can lay up to 3000 eggs per day during peak reproductive seasons, which amounts to approximately one egg every minute. The queen is also able to control the sex of the eggs she lays by selectively fertilizing them. Fertilized eggs develop into worker bees (female), while unfertilized eggs develop into drones (male).
Drones: The Male Bees with a Single Purpose
Drones are the male bees in a colony, and their only purpose is to mate with the queen bee. They are larger than worker bees and possess large eyes, which aid them in locating a queen during the mating process. Drones develop from unfertilized eggs and do not participate in other hive activities, such as foraging or defending the colony. After mating, the drone dies as the process results in a fatal injury.
Mating typically occurs during a nuptial flight, which involves the queen bee and several drones flying together outside of the hive. The queen mates with multiple drones during this flight, collecting and storing sperm in her spermatheca, a specialized organ that preserves sperm for later use. This stored sperm can be used to fertilize thousands of eggs throughout the queen’s lifetime, which can last up to five years.
Worker Bees: The Caretakers of the Colony’s Reproductive Process
Worker bees are female bees that are unable to reproduce due to underdeveloped reproductive systems. They play a critical role in caring for the eggs, larvae, and pupae within the hive. Worker bees maintain the brood chamber’s temperature, ensuring that it remains at an optimal 32-35°C (90-95°F) for the proper development of the eggs and larvae.
Once the eggs are laid by the queen bee, worker bees tend to them by cleaning the cells and ensuring that the larvae are well-fed. They feed the developing larvae with a combination of pollen, honey, and a secretion known as royal jelly. The composition of this diet determines the development of the larvae; a diet predominantly composed of royal jelly will result in the development of a new queen bee.
Functions of Different Body Parts
The different body parts of a bee have various functions, and each body part plays an essential role in the bee’s survival and the functioning of the hive.
The Multifaceted Functions of a Bee’s Head: Sensory Organs and Feeding Mechanisms
The head of a bee is an intricate and highly specialized structure, housing various sensory organs and feeding mechanisms that are vital for the insect’s survival, foraging, and communication. Understanding these elements and their significance can provide valuable insight into the world of bees and their fascinating behaviors.
Compound Eyes: Vision and Color Detection
Bees possess two large compound eyes, which are made up of thousands of individual facets called ommatidia. Each ommatidium works as an independent light receptor, and together, they create a mosaic image that allows the bee to see in multiple directions simultaneously. Additionally, bees are sensitive to ultraviolet light, which helps them detect colors and patterns in flowers that are invisible to humans. This ability is crucial for locating nectar-rich flowers while foraging.
Ocelli: Navigational Aid and Light Intensity Sensing
Apart from the compound eyes, bees have three simple eyes called ocelli (singular: ocellus) located on the top of their head. These eyes are not used for detailed vision like the compound eyes but rather for detecting light intensity and assisting in navigation. By sensing the position of the sun, ocelli help bees maintain their orientation during flight, even on cloudy days.
Antennae: Chemoreception, Air Movement Detection, and Temperature Sensing
The antennae, a pair of long, segmented appendages located on the bee’s head, serve as multi-functional sensory organs. Packed with sensory cells, the antennae can detect chemical cues, such as pheromones, which play a vital role in communication within the colony. They also pick up on air movement, helping bees navigate through their environment and avoid obstacles. Moreover, the antennae can sense temperature changes, which is particularly important when maintaining the optimal temperature within the hive.
Mouthparts: Nectar and Pollen Collection and Processing
A bee’s head also features complex mouthparts, which are essential for feeding and collecting resources. The primary components of the mouthparts include the mandibles, proboscis, and glossa. The mandibles, or jaws, are used for various tasks, such as manipulating wax for comb construction, grooming, and handling food. The proboscis is a long, flexible tube that the bee uses to suck nectar from flowers, while the glossa, or tongue, assists in the process by helping to draw nectar up into the proboscis. Additionally, the bee’s mouthparts are involved in processing pollen, which is essential for providing protein to developing larvae.
The Complex Functions of the Thorax in Bees: Flight, Foraging, and Thermoregulation
The thorax, the central region of a bee’s body, is a vital and multifunctional structure that plays a crucial role in the bee’s ability to survive and thrive. In this section, we’ll dive deeper into the anatomy of the bee’s thorax and discuss the significance of its various components in supporting flight, foraging, and thermoregulation.
Flight Mechanics: Wings and Muscles
The thorax contains two pairs of wings, with the forewings being larger than the hindwings. These wings are connected to the thorax by a series of joints, which allow them to move independently or in coordination with one another. The wings’ movement is powered by two main sets of muscles: the indirect flight muscles and the direct flight muscles. The indirect flight muscles, which are responsible for the up-and-down motion of the wings, are attached to the thorax’s inner walls, while the direct flight muscles control wing twisting and folding.
Bees are remarkably agile flyers, capable of hovering, flying forward and backward, and making quick turns. These advanced flight capabilities are primarily due to their ability to flap their wings at a rapid rate, which can be as high as 230 times per second. This, in turn, is made possible by the thorax’s robust muscular structure and the precise coordination between the bee’s wings and muscles.
Foraging Capabilities: Legs and Pollen Collection
A bee’s thorax also houses its six legs, which are essential for foraging activities. Each leg is divided into five segments and is equipped with specialized structures that aid in various tasks. The forelegs, for instance, feature a comb-like structure used for cleaning the bee’s antennae and eyes. The middle and hind legs, on the other hand, are designed for walking, grasping flowers, and collecting pollen.
The hind legs are particularly adapted for pollen collection, with structures like the pollen press and the pollen basket. The pollen press helps the bee form pollen pellets by compressing the collected pollen, while the pollen basket, a concave surface on the outer side of the tibia, holds these pellets securely as the bee flies back to the hive.
Thermoregulation: Maintaining Optimal Temperatures
Lastly, the thorax plays a crucial role in thermoregulation, helping the bee maintain its body temperature and ensure that the hive stays within an ideal temperature range. Bees can generate heat by rapidly contracting and relaxing their flight muscles without actually moving their wings. This heat is then distributed throughout the thorax and the rest of the body, allowing the bee to function optimally even in colder conditions.
Thermoregulation is especially important for honeybees, as they need to maintain a consistent temperature within the hive to ensure the proper development of their brood and the successful storage of honey. By using their thorax muscles to generate heat, bees can maintain the hive’s temperature at around 34-35°C (93-95°F), which is essential for the survival and productivity of the colony.
The Multifaceted Abdomen of a Bee: Digestion, Reproduction, Respiration, and More
The abdomen of a bee is an incredibly complex and essential component of its anatomy, responsible for carrying out a range of vital functions that contribute to the overall well-being of both the individual bee and the colony as a whole. This in-depth analysis will explore the key aspects of the bee’s abdomen and the various roles it plays in their survival and success as a species.
Digestive System: Processing Nectar and Pollen
The bee’s digestive system, housed within the abdomen, plays a crucial role in processing the nectar and pollen collected by the bee as it forages. The bee’s stomach, or crop, stores the nectar until it can be transferred to the hive or used for the bee’s own energy needs. Pollen, on the other hand, is stored in the hindgut and later mixed with digestive enzymes to break it down and absorb nutrients.
Circulatory and Respiratory Systems: Delivering Oxygen and Nutrients
The bee’s open circulatory system, also located in the abdomen, is responsible for delivering nutrients and oxygen throughout the body. Hemolymph, the insect equivalent of blood, circulates throughout the bee’s body cavity, supplying cells with vital nutrients and oxygen. The respiratory system, consisting of a network of tracheae and air sacs, ensures that the bee’s tissues receive an adequate supply of oxygen. Tiny openings called spiracles allow for the intake of oxygen and the release of carbon dioxide.
Reproductive System: Ensuring the Continuation of the Colony
The reproductive system of the bee is also situated within the abdomen, and its specific functions vary depending on the type of bee. In queen bees, the abdomen houses the reproductive organs and is responsible for producing eggs, ensuring the continuation of the colony. In male bees, or drones, the abdomen contains the reproductive organs necessary for mating with the queen. Worker bees, however, have underdeveloped reproductive systems, as their primary function is to support the colony in non-reproductive ways.
Wax Glands: Building and Maintaining the Hive
Wax glands, found within the worker bee’s abdomen, are essential for the construction and maintenance of the hive. These glands produce beeswax, which is then used to build the honeycomb structure where bees store honey, pollen, and brood. Worker bees manipulate the beeswax with their mandibles to create the intricate hexagonal cells that characterize honeycomb.
The Stinger: A Formidable Defense Mechanism
The bee’s stinger, a highly effective defense mechanism, is located at the tip of the abdomen. It consists of a sharp, barbed lancet connected to a venom sac. When a bee perceives a threat, it uses its stinger to inject venom into the target, causing pain and sometimes serious allergic reactions. In honeybees, the stinger is barbed, and detaches from the bee’s body after use, leading to the bee’s death.
