A bumblebee 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 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.
Bombus lapidarius is a species of bumblebee in the subgenus Melanobombus. Commonly known as the red-tailed bumblebee, B. lapidarius can be found throughout much of Central Europe. Known for its distinctive black and red body, this social bee is important in pollination.
Bombus hyperboreus is a species of Arctic bumblebee with a circumpolar distribution. The species is primarily found in the arctic areas of Greenland, northern Scandinavia, and Russia. In 2015 the nearctic species, Bombus natvigi, was separated from this species, based on genetic analysis. Accordingly, Bombus hyperboreus is limited to the Palaearctic, despite older literature listing this species as occurring in the Nearctic.
Bombus citrinus is a species of bumblebee known commonly as the lemon cuckoo bumblebee due to its lemon-yellow color. It is native to eastern North America.
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. It is known commonly as the indiscriminate cuckoo bumblebee.
Bombus suckleyi is a species of bumblebee known commonly as Suckley's cuckoo bumblebee, named after biologist George Suckley. Suckley's bumble bee is a generalist pollinator and represents a rare group of obligate, parasitic bumble bees. Suckley's bumble bee is a social-parasite because it invades the nests of the host bumble bees, including the western bumble bee, and relies on host species workers to provision its larvae. It is native to northwestern North America, including Alaska and parts of western and central Canada and the western United States.
Bombus lucorum, the white-tailed bumblebee, is a species of bumblebee, widespread and common throughout Europe. This name has been widely used for a range of nearly identical-looking or cryptic species of bumblebees. In 1983, Scholl and Obrecht even coined the term Bombus lucorum complex to explain the three taxa that cannot be easily differentiated from one another by their appearances. A recent review of all of these species worldwide has helped to clarify its distribution in Europe and northern Asia, almost to the Pacific. B. lucorum reaches the Barents Sea in the North. However, in southern Europe, although found in Greece it is an upland species with its distribution never quite reaching the Mediterranean.
Bombus pensylvanicus, the American bumblebee, is a threatened species of bumblebee native to North America. It occurs in eastern Canada, throughout much of the Eastern United States, and much of Mexico.
Bombus nevadensis, the Nevada bumblebee, is a species of bumblebee. It is native to North America, where it occurs from Alaska to California in the west, and east to Wisconsin, and in Arizona, New Mexico, and Mexico.
Bombus occidentalis, the western bumblebee, is one of around 30 bumblebee species present in the western United States and western Canada. A recent review of all of its close relatives worldwide appears to have confirmed its status as a separate species.
Bombus cockerelli, Cockerell's bumblebee, is a yellow and black bumblebee known only from fewer than 30 specimens, collected at a few high-altitude localities in the White Mountains of New Mexico, all within an area of less than 300 square miles (780 km2), giving it the smallest range of any of the ~250 species of bumblebees in the world.
Franklin's bumblebee is known to be one of the most narrowly distributed bumblebee species, making it a critically endangered bee of the western United States. It is known only from a 190-by-70-mile area in southern Oregon and northern California, between the Coast and Sierra-Cascade mountain ranges. It was last seen in 2006. Franklin's bumblebee is known to collect nectar and pollen from several wildflowers, such as lupine, California poppy, and horsemint, which causes it to be classified as a generalist forager.
Bombus magnus is a species of bumblebee. It is native to Europe. It is known by the common name northern white-tailed bumblebee.
Bombus centralis, the central bumblebee, is a species of bumble bee found in parts of Canada and the western United States. The species was first described by Ezra Townsend Cresson in 1864.
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.
Bombus borealis is a species of bumblebee known commonly as the northern amber bumblebee. It is native to northern North America, where it occurs across Canada and Alaska and the northern and eastern contiguous United States.
Bombus griseocollis is a species of bumblebee known commonly as the brown-belted bumblebee. It is native to much of the United States except for the Southwest, and to the southernmost regions of several of the provinces of Canada.
Bombus perplexus is a species of bumblebee known by the common name confusing bumblebee. It is native to northern North America, where it occurs across Canada and into the eastern United States.
Bombus rufocinctus is a species of bumblebee known by the common name red-belted bumblebee. It is native to North America where it has a wide distribution across Canada and the western, midwestern, and northeastern United States. It may occur in Mexico.
