Bombus ashtoni is a species of cuckoo bumblebee. This means that it parasitizes closely related species such as Bombus affinis, Bombus terricola, and Bombus fervidus by residing in the nests of these bumblebees and tricking the bees into providing resources such as food for them.
B. bohemicus is part of the order Hymenoptera, which includes ants, bees, wasps, and sawflies, the family Apidae, specific to bees, and the genus Bombus, which includes all bumblebees. B. bohemicus belongs to the subgenus Psithyrus, or the cuckoo bees, which includes 29 species found in Europe and the New World.
Its main hosts are bumblebees of the subgenus Thoracobombus such as Bombus pascuorum (common carder bee). In continental Europe, it also parasitizes nests of brown-banded carder bees (Bombus humilis) and early bumblebees (Bombus pratorum; although the latter is a Pyrobombus, not a Thoracobombus).
Bombus cryptarum is a species of bumblebee. It is native to the northern hemisphere, where it is "one of the most widespread bumblebees in the world." It occurs throughout Europe, Asia, and North America. It is known commonly as the cryptic bumblebee. The species' complete distribution is unclear due to taxonomic uncertainties.
Bombus distinguendus, the great yellow bumblebee, is a species of bumblebee found in Austria, Belgium, the Czech Republic, Denmark, Finland, France, Germany, Great Britain, Hungary, Lithuania, Poland, Romania, Slovakia, Switzerland, northern Russia, and North America.. It is endangered species in Ireland. In Great Britain, it survives on the far north Highlands coast, Orkney, and the Western ...
Bombus hortorum belongs to the Bombus, or bumblebee, genus. It holds the position of being one of the six most common bumblebees throughout Europe. Of the six species, only two are long-tongued: B. hortorum and B. pascuorum. It is closely related to the species Bombus ruderatus.
Bombus hyperboreus is a species of Arctic bumblebee with a circumpolar distribution. The species is primarily found in the arctic areas of Canada, Alaska, Greenland, northern Scandinavia, and Russia. However, more recently (2015) the nearctic bumble bee, Bombus natvigi has been separated from this species, based on genetic analysis.
Bombus interruptus Bombus insularis is a species of bumblebee in the subgenus Psithyrus, the cuckoo bumblebees. It is native to northern and western North America, where it occurs throughout Canada, Alaska, the northern United States, and some western states.
Bombus lapidarius often experiences parasites, including different species from the Psithyrus subgenus which attempt to usurp its nest. All cuckoo bumblebee species lack a worker caste - instead the female queen cuckoo bee invades the nest of a host species and lay her eggs there.
Bombus lapponicus is a species of bumblebee. It is native to northern Europe, where it occurs in Finland, Norway, Sweden, and Russia. This is generally a common bee. The species' exact range is unclear because many collections are actually other bumblebee taxa. This species lives in taiga and tundra. It feeds on a variety of plant taxa.
Bombus pascuorum, the common carder bee, is a species of bumblebee present in most of Europe in a wide variety of habitats such as meadows, pastures, waste ground, ditches and embankments, roads, and field margins, as well as gardens and parks in urban areas and forests and forest edges.
Bombus polaris is a common Arctic bumblebee species. B. polaris is one of two bumblebees that live above the Arctic Circle. The other is its social parasite Bombus hyperboreus. B. polaris is a social bee that can survive at near freezing temperatures. It has developed multiple adaptations to live in such cold temperatures.
Bombus ruderatus, the large garden bumblebee or ruderal bumblebee, is a species of long-tongued bumblebee found in Europe and in some parts of northern Africa. This species is the largest bumblebee in Britain and it uses its long face and tongue to pollinate hard-to-reach tubed flowers.
The word "bumblebee" is a compound of "bumble" + "bee" — "bumble" meaning to hum, buzz, drone, or move ineptly or flounderingly. The generic name Bombus, assigned by Pierre André Latreille in 1802, is derived from the Latin word for a buzzing or humming sound.
Bombus variabilis (=intrudens) is recorded as breeding as a parasite of colonies of Bombus pensylvanicus (Williams et al. 2014): females usurp established colonies and lay eggs which the workers of the host colony then rear to adulthood. Its host species is associated with open fields and grasslands (Colla and Dumesh 2010).

Only three species (Common carder, Bombus pascuorum; Moss carder, Bombus muscorum; and Brown-banded carder) are all-ginger, and consequently the trio can be easily split off from other bumblebees.
The scarce Broken-belted bumblebee (Bombus soroeensis) can be very similar but the yellow abdominal band extends forwards onto the first abdominal segment (always only on the second segment in Buff-tailed bumblebees), and the front of the white tail often contains a thick orange suffusion, rather than yellow.
Bombus ternarius, commonly known as the orange-belted bumblebee or tricoloured bumblebee, 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 parts of Canada.
Cuckoo bumblebees are members of the subgenus Psithyrus in the bumblebee genus Bombus. Until recently, the 29 species of Psithyrus were considered to constitute a separate genus. They are a specialized lineage which has lost the ability to collect pollen and to rear their brood.
