A bumblebee nest is not organised into hexagonal combs like that of a honeybee; the cells are instead clustered together untidily. The workers remove dead bees or larvae from the nest and deposit them outside the nest entrance, helping to prevent disease. Nests in temperate regions last only for a single season and do not survive the winter. [47]

There is a high risk of injury or death in foraging, which the queen offsets by allowing the worker bees to do this dangerous task. However, towards the end of the colony cycle, when the worker population has begun to dwindle, the queen is best used as a forager, to provide sustenance for the next generation of reproductive bees.

B. terrestris bees exhibit alloethism, which is where different sized bees perform different tasks. This kind of behavior can be seen most often in foraging activities. Larger bees are more often found foraging outside the nest and will return to the nest with larger amounts of nectar and pollen.
Unlike the nests of honeybees or paper wasps, the nests of B. impatiens do not have a predictable pattern. The bees lay egg clumps all over inside the nest instead of having one brood area around which the workers' distribution center is arranged. [11] Within the nest there is a special division of labor and social organization.
Bombus ternarius, commonly known as the orange-belted bumblebee or tricolored bumblebee, [2] is a yellow, orange and black bumblebee.It is a ground-nesting social insect whose colony cycle lasts only one season, common throughout the northeastern United States and much of Canada. [3]
When selecting a host nest, B. bohemicus queens preferentially attack larger host nests, [14] but the size of nest invaded (measured by number of host bees) is correlated to the mortality rate of the invading queen. [15] Smaller nests, which contain fewer workers, will produce fewer, and smaller, reproductive B. bohemicus. [14]
The nests that host Suckley's bumble bee are primarily underground cavities that have been created naturally or by other animals such as abandoned rodent nests. [7]: 13 Suckley's bumble bee females also require sites where they hibernate during the winter after mating. Bumble bees are generally known to hibernate close to the ground surface or ...
