A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus Bombus, part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini , though a few extinct related genera (e.g., Calyptapis ) are known from fossils .
Bombus impatiens, the common eastern bumblebee, is the most commonly encountered bumblebee across much of eastern North America. [3] They can be found in the Eastern temperate forest region of the eastern United States , southern Canada , and the eastern Great Plains . [ 4 ]
The cycle technically completes when the queen dies, the reproductive gynes leave the nest, or both. [3] Polygynous phases can begin (and often do begin) if the queen is replaced by more than one new reproductive queen. [1] Monogynous phases are initiated by conflicting queen–queen interactions that kill all but one rival reproductive queens. [2]
There are circumstances, however, where a colony can become queenless, and therefore certain males must adapt to this surrounding in order to increase paternity. In ants and honeybees, there are two different types of monogynous settings. Type A are monogynous, queenright colonies where the queen is the mated female and everyone else is unmated.
Bombus terrestris, the buff-tailed bumblebee or large earth bumblebee, is one of the most numerous bumblebee species in Europe. It is one of the main species used in greenhouse pollination , and so can be found in many countries and areas where it is not native, such as Tasmania . [ 2 ]
Suckley’s cuckoo bumble bee may be classified as endangered under the Endangered Species Act after a recommendation from the U.S. Fish and Wildlife Service. This social parasite is native to 15 ...
The early bumblebee or early-nesting bumblebee (Bombus pratorum) is a small bumblebee with a wide distribution in most of Europe and parts of Asia. It is very commonly found in the UK and emerges to begin its colony cycle as soon as February which is earlier than most other species, hence its common name. [ 1 ]
Bombus transversalis is a bumblebee specifically native to the Amazon Basin. [2] [3] [4] It is most notable for its surface-level colonies which are built by the workers on the rainforest floor. Unlike its relatives, B. transversalis is able to thrive in a humid climate and fend off a wide range of predators because of its resilient nests.
