Pyrobombus
''Pyrobombus'' (also known as Fiery-tailed bees) is a subgenus of bumblebees, with its center of diversity, centres of diversity in Central Asia and north-western North America. Nearly a fifth of all ''Bombus'' species fall within ''Pyrobombus'' and its member species vary considerably in size, appearance and behaviour. it covers 43 species of bees and is the largest subgenus of bumblebees, covering almost 50% of the North American fauna. They are seen to be declined by 6%, which may be an undervalued statistic, although not as high as other groups of bees. ''Pyrobombus'' bees also face issues such as climate change, loss of habitat, urbanization, and industrial agriculture. This subgenus of bees can Pollination, pollinate that helps plants fertilise and grow fruit that is essential to the biodiversity and life of the environment. Commonly, ''Pyrobombus'' bees are used for beekeeping as they are pollinators. They can be for wax, honey, venom, combs, and such which may be collected fo ...

Bombus Bimaculatus
The two-spotted bumble bee (''Bombus bimaculatus'') is a species of social bumble bee found in the eastern half of the United States and the adjacent south-eastern part of Canada. In older literature this bee is often referred to as ''Bremus bimaculatus'', ''Bremus'' being a synonym for ''Bombus''. The bee's common name comes from the two yellow spots on its abdomen. Unlike many of the other species of bee in the genus ''Bombus,'' ''B. bimaculatus'' is not on the decline, but instead is very stable. They are abundant pollinators that forage at a variety of plants. Taxonomy and phylogeny ''Bombus bimaculatus'' is in the subgenus '' Pyrobombus'', which is closely related to the subgenera '' Alpinobombus'' and ''Bombus'' out of the 15 total. Within '' Pyrobombus'', ''B. bimaculatus'' is most closely related to '' B. monticola, B. sylvicola, and B. lapponicus.'' Additionally, ''B. bimaculatus'' can oftentimes be confused with '' B. impatiens'' and '' B. griseocollis'', as their co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombus Pratorum
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. There is even some evidence that the early bumblebee may be able to go through two colony cycles in a year. Like other bumblebees, ''Bombus pratorum'' lives in colonies with queen and worker castes. ''Bombus pratorum'' queens use aggressive behavior rather than pheromones to maintain dominance over the workers! Description and identification The queen is black with a yellow collar (the band around the front of the thorax), another yellow band on the first tergite (abdominal segment), and red colouration on the tail (terga 5 and 6). The male has a wider yellow collar, yellow colouration on both terga 1 and 2, and a red tail, also. The workers are similar to the queen, but ...

Bombus Bifarius
''Bombus bifarius'', the two-form bumblebee, is a species of eusocial bumblebee of the subgenus ''Pyrobombus''. ''B. bifarius'' inhabits mountainous regions of western North America, primarily the states of Colorado and Utah. Its common name refers to a historical artifact, in that it was believed that this species had a color polymorphism, with a red-tailed nominate form and a black-tailed ''nearcticus'' form, present in the species. This polymorphism has recently been shown to belong instead to a cryptic sister species, '' Bombus vancouverensis'', that occupies almost the entirety of the range of what was formerly classified as ''bifarius''; true ''bifarius'' only has a red form, so it is not "two-formed" at all.Ghisbain, G., J. D. Lozier, S. R. Rahman, B. D. Ezray, L. Tian et al. (2020) Substantial genetic divergence and lack of recent gene flow support cryptic speciation in a colour polymorphic bumble bee (''Bombus bifarius'') species complex. Syst. Entomol. 45: 635–652. d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombus Hypnorum
The tree bumblebee or new garden bumblebee (''Bombus hypnorum'') is a species of bumblebee common in the European continent and parts of Asia. Since the start of the twenty-first century, it has spread to the United Kingdom and Iceland. These bumblebees prefer habitats that others do not, allowing them to pollinate flowers in areas that many other species do not get to. Description ''Bombus hypnorum'' has a short proboscis and a rounded head. The thorax is usually of a uniformly ginger color (but examples with a darker, or even black thorax occur), the abdomen is covered in black hair, and the tail is always white. In workers, the first tergite (abdominal segment) is black-haired, but a proportion of males may have ginger hairs intermixed with the black hair, both on the face and on the first abdominal tergum. On the European continent, individuals with extended yellow coloration exist. Workers are often (but not always) small, while drones are much bigger in comparison. The ...

Alpinobombus
The list presented here is a checklist of world bumblebees (Tribe Bombini) based on the ''Bombus'' phylogeny presented by Cameron ''et al'' (2007) and grouped by subgenus following the revision of Williams ''et al'' (2008). The bumblebee fossil record extends back to the Late Eocene in North America and England with the most diversity of fossils found during the Miocene. The fossil species were discussed and revised by Dehon ''et al'' (2019).

Bombus (Pyrobombus) Pratorum On Buddleia - Flickr - S
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. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are social insects that form colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Cuckoo bumblebees are brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumblebee species, kill the resident queens ...
