How Do Bees Make Honey

The colony of the honey bee
are social insects living together in large group or family called a colony.
The bees' nest inside the hive consists of several wax combs each containing
many cells in which bees use for rearing their baby bees and to store food.
The bees organize their affairs so well in their dwelling and devote
themselves to the welfare and survival of their colony.
A bee colony
is made of three different castes: A queen, worker bees who form the great
majority of the colony and the drones. The queen is the mother of the colony
whose only function is to lay eggs from which all bees develop. The sole
function of the drones is to fertilize the virgin queens, whereas the worker
bees perform all tasks that the colony needs. In summer the colony contains
40,000 to 80,000 worker bees and a few hundred drones and in winter about
10,000 to 20,000 worker bees and no drones. Bees born in spring or in summer
live on the average no more than six weeks, whereas those born in September
or later live six months and more. This seasonal variability in the life
span of individuals is due to the fact that spring or summer bees do much
work with a lot of energy spent, and that those emerge in autumn stay
inactive within the hive huddled together in a cluster during the wintertime
and eat the stored food.
A worker bee,
after emerging from her birth cell as a mature bee lives approximately six
weeks in summer, spending the first three weeks of her life inside the hive
and is termed a house bee or nurse bee. In this stage she cleans cells,
feeds the older and young bees, feeds the queen, builds wax combs, stores
nectar and seals the honey cells, removes debris and dead bees, ventilates
the hive and guards the hive entrance. After this period she becomes a field
bee (forager) and works the second half of her life outside the hive
collecting nectar, pollen, propolis and water.
vegetarians. They eat two kinds of food, honey and pollen; honey is made
from the nectar of the flowers and provides the bees with carbohydrate. The
pollen is derived from the anthers of flowers and is the source of protein,
vitamins and minerals.
is the most important job of foraging bees. They fly diligently and
tirelessly every day from morning till dusk in all directions and at various
heights and at a distance of 3 to 5 kilometers from the hive prospecting for
plants and trees producing nectar which they collect from the heart of
the basic raw product from which honey is made. It is a mixture of water and
sugar that flowers produce from their nectaries. Nectar contains 20 to 60%
sugars generally cane sugar. The water content varies between 40 to 80%.
Besides sugar, nectar contains minerals, organic acids, vitamins, pigments
and aromatic substances.

and nurse bees are involved in the process of honey making. The process
begins when a forager leaves the hive looking for flowers to collect nectar.
When a flower is found, the bee sucks the nectar out of the flower with her
proboscis (tongue) and stores it in a special sack in her body called the
honey stomach to be transferred to the honey-making bees in the hive. The
honey stomach holds about 4 mg of nectar that is about half the weight of
the bee. If the nectary is empty the bee flies to another flower. A bee may
need to visit between 50 to 150 flowers in order to fill her honey stomach
depending on the flower species. For instance, a load can be obtained from a
few rich-nectar producing flowers such as eucalyptus or citrus whereas a
load can be obtained by visiting hundreds of small flowers of clover. It
takes about 30 minutes to several hours to collect a load, depending on how
plentiful and how far away the nectar source is. A forager may take hours to
collect a load in poor foraging conditions.
honey stomach is full the bee flies back to the hive. On her way back the
bee adds invertase, an enzyme from her body to the collected nectar. This
begins the process of changing the nectar into honey. The enzyme breaks the
complex plant sugar in the nectar down into simpler and more digestible
sugars for the bees, mainly glucose (grape sugar) and fructose (fruit

In the hive
the nectar is delivered to the house bees who store it in the honeycomb
cells. In the cells water has to be evaporated off the nectar. House bees on
the comb fan their wings to evaporate and thicken the nectar converting it
into honey. Ripened honey has moisture of 17 to 20%. Further enzymes added
to prevent it from fermentation and attack by bacteria while it is stored in
the hive. Once this process is finished the house bees will then cover the
top of each filled up cell with a thin beeswax cap to make it airtight,
sealing it for future use. When this is done, they move to the next empty
comb starting all over again.

colony can produce 30 to 50 kg of surplus honey per year. The bees in the
same colony visit about 4 million flowers to make one kilogram of honey. The
honeys they produce vary in color, flavor and viscosity; this difference
depends upon the floral source from which the nectar was derived. The nectar
from some plants produces a light, mild flavored honey. Nectar from other
plants produces a dark, strong flavored honey.
will go on collecting and storing more nectar as long as there is nectar
available in the pasture and there are empty cells in the hive to store it
in, however much abundance of honey the hive contains. A returning forager
with load of nectar makes her way to the combs and begins to inform the
others about the source and direction of nectar to recruit more foragers to
the area of nectar. She does so by performing special movements on the
surface of the comb known as “dance” and does that for seconds or a minute.
While she is dancing some bees gather closely around her and learn from the
dance and touch her with their antennae. The dancing forager makes stops to
give nectar to those bees following and watching the dance to learn its
scent and taste. The dancer then runs to another place on the combs and
repeats the dance before another group of bees. After the dance has ended,
she makes another trip to the source of nectar, and those bees who have
followed the dance leave the hive to search for the nectar. When the
recruited bees return to the colony with load they in their turn recruit
perform different dances to convey different information. When the source of
nectar is near the hive i.e., less than 100 meters away the forager will
perform a round dance, and if is far away the bee will perform the waggle
The round dance
round dance the bee runs around in a little circle first one way, then turns
round and runs in the opposite direction of the circle. The round dance
tells the bees that the food is near the hive and of its taste and smell,
but gives no information about the direction of the food source.
The waggle dance
Unlike the simple round
dance, the more complex waggle dance gives accurate information about both
the direction and distance of the nectar source. The bee uses the sun’s
position to indicate the direction of the nectar. In a world the waggle
dance indicates the position of the sun, the location of the hive and the
spot where nectar can be found.
The dance can
be described as a half-circle, a straight line, a half-circle to the right
and a half-circle to the left and so on. During the straight run the bee
wags her abdomen from side to side to indicate distance to the nectar
source, and the longer the trip to the nectar source the quicker the waggles
of the dance and greater their number.
If the nectar
source and the sun are in the same direction, the bee runs the straight line
between the two half-circles with her head up towards the sun indicating to
the bees ‘you can find the nectar by flying toward the sun’.
If the nectar
source and the sun are in opposite direction the bee runs the straight line
with her head down indicating the nectar source is opposite the direction of
the sun. If the nectar is at the right or left of the sun, the bee orients

surplus honey for a rainy day and feed on this honey all year round for
their survival, particularly during the cold winter months when no flowers
and nectar available. An average colony requires about 40 to 100 kg of honey
to maintain itself through a year.
