Bee hives are alive with activity. Have you ever wondered about the life of a bee? How is a bee colony organized? How do bees construct their hives? How do bees make honey? What is life like for a bee? Read on to find out.
Why Are Honey Bees Important?
Bees not only provide us with delicious and nutritious honey, but they are crucial to the existence of life on earth. Bees (along with some birds, bats, and insects) are needed to pollinate the flowers of many of the fruits, nuts, and vegetables humans rely on for food. Without bees, food would be in very short supply.
Honey bees also provide us with honey. They produce this honey to use as their food source in the winter. The average honeybee colony can make 60 pounds (27 kilograms) of honey per year.
A single honey bee worker produces about 1/12 of a teaspoon of honey in her lifetime. It takes many thousands of honeybees to produce one pound of honey.
How Is a Honey Bee Hive Organized?
There are three types of bees in a bee hive, plus bees which are not yet “born.”
- Queen Bee: The hive is organized around the queen bee. Several queen bees will emerge at one time, and a battle ensues among them. Only one queen bee will survive this battle because a hive can have only one queen bee. She is the only bee that can reproduce. She mates with drones during her one mating flight and stores the sperm within her body. She then lays thousands of eggs every day, perhaps millions over her three-to four-year life span.
- Brood: The beehive will also contain brood—eggs, larvae, and pupae. Hatched eggs are larvae. The larvae spin a cocoon for themselves and are then known as pupae. The pupae undergo metamorphoses and emerge from the cocoon as an adult bee.
- Drone Bees: Drones are male bees. Their main function is to fertilize the young queen bee. They can also help with heating and cooling the hive—bees shiver to produce heat and flap their wings to cool the hive. Drones develop from unfertilized eggs. They will feed themselves directly from honey cells in the hive. When food is scarce, drones will be driven from the hive and left to die.
- Worker Bees: Female bees do virtually all the work of the hive. During their short lives, workers keep busy—thus the expression “busy bees.” Worker bees live only five to six weeks in summer, but for about five months in winter.
Worker bees begin their lives as “house bees,” which stay within the hive, and later become field bees, which go out to forage for nectar, pollen, and water to feed the hive population.
The youngest bees clean the cells and tend to the brood. They produce wax from glands on their body and shape it into the hexagon-shaped cells that will be used for the eggs laid by the queen and for honeycombs.
They seal the cells of the honeycombs with more wax after the nectar has evaporated enough to have become honey. Towards the end of their time as worker bees, they ventilate, guard, and defend the hive.
Characteristics of Each Member of the Hive
|Number per hive||One||Almost all||Less than 0.01 %|
|Duties||Lay eggs||Care for the queen, build the hive, forage for nectar, make honey, tend the brood, heat and cool the hive, and defend the hive.||Inseminate the Queen, and heat and cool the hive.|
The Life Cycle of a Worker Bee
|Age in Days||Job Done|
|1 to 3 days old||Clean cells, warm brood nest|
|4 to 11 days old||Feed larvae with honey and pollen|
|7 to 12 days old||Tend to the Queen bee|
|12 to 17 days old||Make wax, construct comb, tend honey|
|18 to 21 days old||Guard and ventilate hive|
|22 days old and over||Become a field bee and forage|
How Do Bees Build a Bee Hive?
Wild honey bees make hives in rock crevices, hollow trees, and other areas—sometimes even an old box or inside the walls of a building.
Domesticated honeybees are brought to a hive constructed by a beekeeper. Artificial hives are usually square or rectangular in shape and are made of untreated wood.
Honey bees construct honeycombs within the enclosure (natural or artificial) they have selected for their hive. The honeycombs are composed of six-sided cells. The hexagon shape is optimal because it requires less wax and can hold more honey. The cells are used to store honey, nectar, and brood.
The worker bees convert the sugar content of honey into wax in a specific wax-producing gland in their bodies. The wax then oozes through the bee’s pores, producing tiny flakes of wax on the bee’s abdomen. The worker bees chew these pieces of wax until they become soft and moldable, and then they form the wax into the cells of a honeycomb.
How Do Bees Make Honey?
Worker bees produce honey from the nectar that they gather from flowers. Pollination is a by-product of their quest for nectar. As they fly from flower to flower, a bit of pollen sticks to their bodies and then rubs off at the next flower they visit. This transfer of pollen from flower to flower is called pollination.
The nectar is extracted from flowers with the bee’s straw-like proboscis. The bee drinks the liquid nectar and stores it in a special stomach called the honey stomach. The bee continues to forage, visiting hundreds of flowers until its honey stomach is full.
Within the honey stomach, enzymes break down the complex sugars of the nectar into simpler sugars, which are less prone to crystallization. This process is called inversion.
When a worker bee has a full belly, she returns to the hive and regurgitates the already modified nectar for the hive bees. The hive bees ingest the sugary offering and further break down the sugars.
They then regurgitate the inverted nectar into a cell of the honeycomb, and it is allowed to dry until the water content reaches about 14-18%. The cell is then capped over with a thin layer of wax to seal it until the bees need it (or the beekeeper collects it).
Nectar contains about 80% water, along with complex sugars. Left in its natural state, nectar would ferment. In order to store nectar, bees convert the nectar into honey.
The flavour, smell, and appearance of honey are determined by the kind of flowers visited by the bees that create it.
How Do Bees Communicate?
A foraging bee that has just discovered a great source of nectar needs to be able to tell the other workers where to find it. She does it by doing a little “dance.”
If the flowers are within 30 yards, the bee will do a “round dance.” The bee flies around in a circle and when she’s made a complete circuit, she reverses direction and flies around again.
She continues to reverse direction after each circuit. This dance tells the other bees that the flowers are nearby. The other bees also pick up the scent of the flowers from the dancing bee, so they know the scent of the flower they need to look for.
If the source is more than 30 yards away, the bee does the “Waggle Dance.” First, she flies in a straight line while vibrating her abdomen from side to side. When she finishes that straight run, she turns to the left, flies around in a half circle back to the beginning of the straight line; then she flies forward again doing the waggle dance.
When she gets to the top this time, she turns right, makes a half circle and comes back to the beginning. She will repeat this pattern several times.
If it’s a rich food source, she is very motivated to get the attention of the other bees, so she’ll waggle like crazy. When she has their attention, she’ll feed them some of the nectar she’s found. But now comes the most remarkable part.
If the sun is straight ahead, and the food source is directly in front of the hive, the waggle line will be straight up the face of the comb. If the food source is behind the hive, she dances down the face of the comb.
But what if the food source isn’t in a straight line in front or behind the hive? The bees have it figured out. The bee will adjust the waggle to match the number of degrees the source is from the sun. For instance, if the food source is 60 degrees to the left of the sun, the bee will waggle 60 degrees to the left of vertical.
If other bees discover the same source later on in the day, the dance may change direction and degrees to account for the sun’s movement. The angle is always relative to the sun.
What Is Colony Collapse Disorder?
In the fall of 2006, beekeepers in North America began reporting the disappearances of entire colonies of bees, seemingly overnight. In the U.S. alone, thousands of bee colonies were lost to colony collapse disorder (CCD).
Theories about the causes emerged almost as quickly as the bees disappeared. No single cause or definitive answer has yet been identified. Most researchers expect the answer to lie in a combination of contributing factors.
The theories about the causes of Colony Collapse Disorder range from climate change, the practices of beekeepers, pesticide use, pathogens, parasites, and environmental toxins, genetically modified crops, and even electromagnetic radiation (from cell phones).
Beware of Fake Honey
Food-safety experts have found that some honey isn’t actually honey, but a concoction of corn or rice syrup, malt sweeteners or “jiggery” (cheap, unrefined sugar), plus a small amount of genuine honey. Artificial honey is used to produce many “honey-flavored” items such as candy, baked goods, cereal, or tea.
Adulterated honey, often honey imported from China, may not only be fake honey, but it may also contain toxins, heavy metals, and other impurities.
Pure honey is amber colored with a subtle scent of flowers; artificial honey has a pungent chemical odor or a fruity smell. Buy honey only from reputable sources. Read the label. It should say 100% honey and nothing else.
Did You Know?
- A 3,000-year-old honeycomb found in the tombs of the pharaohs was perfectly edible.
- A hive will typically make 2 ½ times more honey than it needs. A beekeeper only takes the excess honey, leaving the rest for the bees.
- Occasionally, when hives become overcrowded, the queen and some of the bees from the hive will “swarm.” They abandon the beehive and create a new one elsewhere. A new queen will hatch in the old hive.
- Bees fly about 55,000 miles—1 ½ times around the world—to make just one pound of honey.
