Bees, classified into over 10,000 species, are insects found in almost every part of the world
except the northernmost and southernmost regions. One commonly known species is the honeybee, the
only bee that produces honey and wax. Humans use the wax in making candles, lipsticks, and other
products, and they use the honey as a substance that people eat to maintain life and growth. While
gathering the nectar and pollen with which they make honey, bees are concurrently helping to fertilize
the flowers on which they land. Many fruits and vegetables would not survive if bees did not carry the
pollen from blossom to blossom.
Bees live in a structured environment and social structure within a hive, which is a nest with
storage space for the honey. The different types of bees each perform a distinct function. The worker
bee carries nectar to hive in a special stomach called a honey stomach. Other workers make beewax
and shape it into a honeycomb, which is a waterproof mass of six-sided compartments, or cells. The
queen lays eggs in completed cells. As the workers build more cells, the queen lays more eggs.
All workers, like the queen, are female, but the workers are smaller than the queen. The male
honeybees are called drones; they do no work and can not sting. They are developed from unfertilized
eggs, and their only job is to impregnate a queen. The queen must be fertilized in order to lay more
worker eggs. During the season when less honey is available and the drone is of no further use, the
workers block the drones from eating the honey so that they will starve to death.
