In beekeeping
, a winter cluster is a well-defined cluster of honey bee
s that forms inside a beehive
when the air temperature dips below 54 to 57 °F (12 to 14 °C). Honey bees are but a few insects that survive the winter as a hive. As the outside air temperature decreases the winter cluster becomes tighter and more compact. The bees cling tightly together on the combs
in the hive. The temperature within the winter cluster remains remarkably warm regardless of the outside air temperature. Larger clusters (basketball size) have a better chance for survival than smaller clusters (softball size). The winter cluster within the hive must move throughout the winter to reach the available honey stored in the combs.
Some die-off is expected during the winter. In extended cold weather periods, the incidence of Nosema disease increases and the cluster may weaken as many bees begin dying off.
s forage and queens
lay eggs almost year-round.
In the temperate zones, winter temperatures dip below 54 °F (12 °C) for extended periods. All brood rearing stops for some period during the winter. In early spring, brood rearing resumes inside the winter cluster when the queens starts to lay eggs again. Once a broodnest is established, the cluster must maintain a steady temperature between 94.1 to 98.0 °F (34.5 - 36.7 °C) inside the cluster. If the temperature in areas of the brood nest dips too low the brood dies - also called chilled brood.
Beekeeping
Beekeeping is the maintenance of honey bee colonies, commonly in hives, by humans. A beekeeper keeps bees in order to collect honey and other products of the hive , to pollinate crops, or to produce bees for sale to other beekeepers...

Honey bee
Honey bees are a subset of bees in the genus Apis, primarily distinguished by the production and storage of honey and the construction of perennial, colonial nests out of wax. Honey bees are the only extant members of the tribe Apini, all in the genus Apis...

Beehive (beekeeping)
A beehive is an enclosed structure in which some honey bee species of the subgenus Apis live and raise their young. Natural beehives are naturally occurring structures occupied by honeybee colonies, while domesticated honeybees live in man-made beehives, often in an apiary. These man-made...

Honeycomb
A honeycomb is a mass of hexagonal waxcells built by honey bees in their nests to contain their larvae and stores of honey and pollen.Beekeepers may remove the entire honeycomb to harvest honey...

Brood nest
In subtropical climates, bees may not form a winter cluster at all. Worker beeWorker 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...
s forage and queens
Queen bee
The term queen bee is typically used to refer to an adult, mated female that lives in a honey bee colony or hive; she is usually the mother of most, if not all, the bees in the hive. The queens are developed from larvae selected by worker bees and specially fed in order to become sexually mature...
