Life Cycle Of Honey Bees
As in a few other types
of eusocial bees, a colony generally contains one queen bee, a
fertile female; seasonally up to a few thousand drone bees, or fertile
males; and
tens of thousands of sterile female worker bees. Details vary among the
different species of honey bees, but common features include:
1.
Eggs are laid singly in a cell in a wax honeycomb, produced
and shaped by the worker bees. Using her spermatheca, the queen can choose
to fertilize the egg she is laying, usually depending on which cell she is
laying it into. Drones develop from unfertilised eggs and are haploid,
while females (queens and worker bees) develop from fertilised eggs and
are diploid. Larvae are initially fed with royal jelly produced
by worker bees, later switching to honey and pollen. The exception is a larva
fed solely on royal jelly, which will develop into a queen bee. The larva
undergoes several moultings before spinning a cocoon within the cell, and pupating.
2.
Young worker bees, sometimes called "nurse bees",
clean the hive and feed the larvae. When their royal jelly-producing glands
begin to atrophy, they begin building comb cells. They progress to other
within-colony tasks as they become older, such as receiving nectar and pollen from
foragers, and guarding the hive. Later still, a worker takes her first
orientation flights and finally leaves the hive and typically spends the
remainder of her life as a forager.
3.
Worker bees cooperate to find food and use a pattern of
"dancing" (known as the bee dance or waggle dance) to
communicate information regarding resources with each other; this dance varies
from species to species, but all living species of Apis exhibit
some form of the behavior. If the resources are very close to the hive, they
may also exhibit a less specific dance commonly known as the "round
dance".
4.
Honey bees also perform tremble dances, which recruit
receiver bees to collect nectar from returning foragers.
5.
Virgin queens go on mating flights away from their home colony
to a drone congregation area, and mate with multiple drones before returning.
The drones die in the act of mating. Queen honey bees do not mate with drones
from their home colony.
Colonies
are established not by solitary queens, as in most bees, but by groups known as
"swarms", which consist of a mated queen and a large contingent of
worker bees. This group moves en masse to a nest site which
was scouted by worker bees beforehand and whose location is communicated with a
special type of dance. Once the swarm arrives, they immediately construct a new
wax comb and begin to raise new worker brood. This type of nest founding is not
seen in any other living bee genus, though several groups of vespid wasps
also found new nests by swarming (sometimes including multiple queens).
Also, stingless bees will start new nests with large numbers of
worker bees, but the nest is constructed before a queen is escorted to the
site, and this worker force is not a true "swarm"
