on the 21st 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. When fully developed, they perform a number of tasks (see below). Swarming behavior 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 behaviour in order to establish the first generation in the new home. The most urgent task will be the creation of new beeswax for 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 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.) Progression of tasks Cell cleaning (days 1–2) Brood cells must be cleaned before the next use. Cells will be inspected by the queen and if unsatisfactory they will not be used. Worker bees in the cleaning phase will perform this cleaning. If the cells are not clean, the worker bee must do it again and again. Nurse bee (days 3–12) Nurse bees feed the worker larvae worker jelly which is secreted from glands that produce royal jelly. They will also go into the special cells to create a semi-royal jelly that is similar to the royal but it tastes more like honey. Advanced Nurse Bees (days 6–12) Nurse Bees will then feed royal jelly to the queen larva and drones receive worker jelly for 1 to 3 days at which time they are started on a diet of honey. Wax production (days 13–18) Wax bees build cells from wax, repair old cells, and store nectar and pollen brought in by other workers. Early in the worker's career she will exude wax from the space between several of her abdominal segments. Four sets of wax glands, situated inside the last four ventral segments of the abdomen, produce wax for comb construction.
