Why do Bees Make Honey?
Honeybees collect nectar and store it as honey in their hives. Nectar and honey provide the energy for the bees' flight muscles and for heating the hive during the winter period. Honeybees also collect pollen which supplies protein for bee brood to grow.
The Colony
Honey
bees live in colonies that are often maintained, fed, and transported
by beekeepers. Centuries of selective breeding by humans has created
honey bees that produce far more honey than the colony needs. Beekeepers
harvest the honey. Beekeepers provide a place for the colony
to live and to store honey in. The modern beehive is made up of a
series of square or rectangular boxes without tops or bottoms placed
one on top of another. Inside the boxes frames are hung in parallel,
in which bees build up the wax honeycomb in which they both raise
brood and store honey. Modern hives enable beekeepers to transport
bees, moving from field to field as the crop needs pollinating and
allowing the beekeeper to charge for the pollination services they
provide.
A colony generally contains one breeding female, or "queen"; a few thousand males, or "drones"; and a large population of sterile female “worker” bees. The population of a healthy hive in mid-summer can average between 40,000 and 80,000 bees. The workers cooperate to find food and use a pattern of "dancing" to communicate with each other.
Queen
The queen is the largest bee in the colony. Queens are developed from
larvae selected by worker bees to become sexually mature. The queen
develops more fully than sexually immature workers because she is given
royal jelly, a secretion from glands on the heads of young workers,
for an extended time. She develops in a specially-constructed queen
cell, which is larger than the cells of normal brood comb, and is oriented
vertically instead of horizontally.
She will emerge from her cell to mate in flight with approximately 13-18 drone (male) bees. During this mating, she receives several million sperm cells, which last her entire life span (from two to five years). In each hive or colony, there is only one adult, mated queen, who is the mother of the worker bees of the hive, although there are exceptions on occasion.
Although the name might imply it, a queen has no control over the hive. Her sole function is to serve as the reproducer; she is an "egg laying machine." A good queen of quality stock, well reared with good nutrition and well mated, can lay up to 3,000 eggs per day during the spring build-up and live for two or more years. She lays her own weight in eggs every couple of hours and is continuously surrounded by young worker attendants, who meet her every need, such as feeding and cleaning.
Drones
The male bees, called “drones”, are characterized by eyes
that are twice the size of those of worker bees and queens, and a body
size greater than that of worker bees, though usually smaller than
the queen bee. Their abdomen is stouter than the abdomen of workers
or queen. Although heavy bodied, drones have to be able to fly fast
enough to catch up with the queen in flight. Drones are stingless.
Their main function in the hive is to be ready to fertilize a receptive
queen. Mating occurs in flight, which accounts for the need of the
drones for better vision, which is provided by their big eyes.
In areas with severe winters, all drones are then driven out of the hive. The life expectancy of a drone is about 90 days.
Worker Bees
A worker bee is a non-reproducing female which performs certain tasks
in support of a bee hive. Worker bees undergo a well defined progression
of capabilities. In the summer 98% of the bees in a hive are worker
bees. In the winter, besides the queen, all bees are worker bees. Workers
feed the queen and larvae, guard the hive entrance and help to keep
the hive cool by fanning their wings. Worker bees also collect nectar
to make honey. In addition, honey bees produce wax comb.
Honey Bee Products
Of course, honey is the main honey bee product that we are interested
in here at the National Honey Board! In addition, there are a few other
products of the hive that are also extremely important.
Honey: In the hive the bees use their honey stomachs to ingest
and process the nectar a number of times. It is then stored in the honeycomb.
Nectar is high in both
water content and natural yeasts which, unchecked, would cause the
sugars in the nectar to ferment. After the final regurgitation, the
honeycomb is left unsealed - bees inside the hive "fan" their
wings creating a strong draft across the honeycomb. This enhances evaporation
of much of the water from the nectar. The reduction in water content,
which raises the sugar concentration, prevents fermentation. Ripe honey,
as removed from the hive by the beekeeper, has a long shelf life and
will not ferment.
Beeswax: Worker bees of a certain age will secrete beeswax from a series
of glands on their abdomen. They use the wax to form the walls and
caps of the comb. When honey is harvested, the wax can be gathered
to be used in various wax products like candles and seals.
Pollen: Bees collect pollen in the pollen basket (a concave
area on the hind legs of the bee with special hairs to hold the pollen in
place) and carry it back to the hive. In the hive, pollen is used as a protein
source necessary
during brood-rearing. In certain environments, excess pollen can be
collected from the hive. It is often eaten as a health supplement.
Propolis: Propolis (or bee glue) is created from resins, balsams and
tree saps. Honeybees use propolis to seal cracks in the hive.

For more information about honey bees, beekeeping and related topics, you may turn to several online articles in Wikipedia, from which much of the above content and images were drawn, and which we would like to credit. Many universities also publish beekeeping information online through their cooperative extension programs.
