Worker Bee

A worker bee is any female (eusocial) bee that lacks the full reproductive capacity of the colony's queen bee; under most circumstances, this is correlated to an increase in certain non-reproductive activities relative to a queen, as well. Worker bees occur in many bee species other than honey bees, but this is by far the most familiar colloquial use of the term.

Workers gather pollen into the pollen baskets on their back legs, to carry back to the hive where it is used as food for the developing brood. Pollen carried on their bodies may be carried to another flower where a small portion can rub off onto the pistil, resulting in cross pollination. Almost all of civilization's food supply (maize is a noteworthy exception) depends greatly on crop pollination by honey bees, whether directly eaten or used as forage crops for animals that produce milk and meat. Nectar is sucked up through the proboscis, mixed with enzymes in the stomach, and carried back to the hive, where it is stored in wax cells and evaporated into honey.

Honey bee workers keep the hive temperature uniform in the critical brood area (where new bees are raised). Workers must maintain the hive's brood chamber at 34.4 °C to incubate the eggs. If it is too hot, they collect water and deposit it around the hive, then fan air through with their wings causing cooling by evaporation. If it is too cold, they cluster together to generate body heat.

The life of all honey bees starts as an egg, which is laid by the queen in the bottom of a wax cell in the brood area of a hive. A worker egg hatches after three days into a larva. Nurse bees feed it royal jelly at first, then pollen and honey for six days. It then becomes an inactive pupa.

Honeycombs have hexagonal cells on both sides of a vertical central wall. As shown in the photo, these cells are inclined upward, primarily to retain liquid nectar and honey. During its 14 days as a pupa, sealed in a capped cell, it grows into a worker (female) bee, emerging on the 20th day. In most species of honey bees, workers do everything but lay eggs and mate, though Cape honey bee workers can lay eggs. They build the comb from wax extruded from glands under their abdomen. They clean, defend, and repair the hive. They feed the larva, the queen, and the drones. They gather nectar, pollen, water, and propolis. They ventilate, cool and heat the hive.

When a colony absconds (all bees leave the colony) or divides and so creates a swarm and then establishes a new colony, the bees must regress in their behavior in order to establish the first generation in the new home. The most urgent task will be the creation of new beeswax for comb. Beekeepers take advantage of this by introducing swarms into new or existing colonies where they will draw comb. Comb is much more difficult to come by than honey and requires about six times the energy to create. A newly hived swarm on bar bars (top bar hive) or empty foundation (Langstroth box hive) will often be fed sugar water, which they can then rapidly consume to create wax for new comb (Mature hives cannot be so fed as they will store it in place of nectar, although a wintering hive may have to be fed if insufficient honey was left by the beekeeper.)

Famous quotes containing the words worker and/or bee:

    A worker may be the hammer’s master, but the hammer still prevails. A tool knows exactly how it is meant to be handled, while the user of the tool can only have an approximate idea.
    Milan Kundera (b. 1929)

    Like the bee that now is blown,
    Honey-heavy on my hand,
    From his toppling tansy-throne
    In the green tempestuous land—
    Edmund Blunden (1896–1974)
