The heath humble-bee or small heath bumblebee, Bombus jonellus, is a species of bumblebee, widely distributed in Europe and northern Asia, [2] as well as northern North America. [1]
A fairly small bumblebee, it has body lengths around 16 mm (0.63 in) (queen) and 12 mm (0.47 in) (worker and male). [3] The queen has an average wingspan of 29 mm (1.1 in). The face and proboscis are short. Females (queens and workers) have a predominantly black abdomen with a yellow collar, the first and sometimes second terga yellow, and a white tail. The face is black, occasionally with a patch of yellow fur on the top. Males are similar, but with more yellow; the yellow collar continues on the ventral side, the two first terga are always yellow, and much more yellow fur is found on the face. However, darker forms of the females are seen, as well as forms (sometimes considered subspecies) that differ in the amount of yellow in the fur, and with brownish hairs on the white tail. Among these are B. j. hebridensis (which is endemic to the Hebridean islands of Scotland), [4] B. j. monapiae, and B. j. vogtii. On the Orkney and the Hebrides, a form exists where the males have red tails instead of white. [5]
The heath humble-bee is found in gardens and meadows, as well as on heath and moorland. [3] The bumblebee visits various food sources, such as clover, bird's-foot trefoil, cowberry, thistles, and many others. [5]
The nest, which at most can contain 50 to 120 workers, can be situated both above and under ground. When the climate permits, as in southern England, this species can have two broods a season. A study in northern Sweden shows the males, when patrolling for young queens, do so at tree-top level, marking twigs and leaves with pheromones to attract the queens. [5]
B. jonellus is present in most of Europe and a large part of northern Asia. In the west, it is common from Iceland in the north to the Cantabrian Mountains in northern Spain. It is found beyond the Arctic Circle in Scandinavia and Russia, where it is continuous north of 55ºN, more uneven south of it. In southern Europe, the distribution, too, is patchy, and restricted to the mountains. In Asia, it reaches the Gulf of Anadyr on the Pacific. [2] In United Kingdom, it is common in the south-east, in East Anglia, northern Scotland including the Hebrides, Orkney, and Shetland. [5] It is also found in Canada east to Hudson Bay and Alaska. [6]
The early bumblebee or early-nesting bumblebee 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.
Bombus barbutellus, or Barbut's cuckoo-bee, is a species of cuckoo bumblebee, widespread, if not especially common, in most of Europe.
Bombus vestalis, the vestal cuckoo bumblebee, is a species of cuckoo bumblebee that lives in most of Europe, as well as North Africa and western Asia. It is a brood parasite that takes over the nests of other bee species. Its primary host is Bombus terrestris. After its initial classification as Psithyrus vestalis, this bumblebee recently was reclassified into the genus Bombus, subgenus Psithyrus.
Bombus campestris is a very common cuckoo bumblebee found in most of Europe.
Bombus sylvestris, known as the forest cuckoo bumblebee or four-coloured cuckoo bee, is a species of cuckoo bumblebee, found in most of Europe and Russia. Its main hosts are Bombus pratorum, Bombus jonellus, and Bombus monticola. As a cuckoo bumblebee, Bombus sylvestris lays its eggs in another bumblebee's nest. This type of bee leaves their young to the workers of another nest for rearing, allowing cuckoo bumblebees to invest minimal energy and resources in their young while still keeping the survival of their young intact.
Bombus bohemicus, also known as the gypsy's cuckoo bumblebee, is a species of socially parasitic cuckoo bumblebee found in most of Europe with the exception of the southern Iberian Peninsula and Iceland. B. bohemicus practices inquilinism, or brood parasitism, of other bumblebee species. B. bohemicus is a generalist parasite, successfully invading several species from genus Bombus. The invading queen mimics the host nest's chemical signals, allowing her to assume a reproductively dominant role as well as manipulation of host worker fertility and behavior.
The broken-belted bumblebee or Ilfracombe bumblebee is a species of bumblebee present in most of Europe and parts of Asia.
Bombus monticola, the bilberry bumblebee, blaeberry bumblebee or mountain bumblebee, is a species of bumblebee found in Europe.
Bombus hortorum, the garden bumblebee or small garden bumblebee, is a species of bumblebee found in most of Europe north to 70°N, as well as parts of Asia and New Zealand. It is distinguished from most other bumblebees by its long tongue used for feeding on pollen in deep-flowered plants. Accordingly, this bumblebee mainly visits flowers with deep corollae, such as deadnettles, ground ivy, vetches, clovers, comfrey, foxglove, and thistles. They have a good visual memory, which aids them in navigating the territory close to their habitat and seeking out food sources.
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. It is similar in appearance to Bombus muscorum, and is replacing the species in Northern Britain.
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 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 ruderarius, commonly known as the red-shanked carder bee or red-shanked bumblebee, is a species of bumblebee found in Eurasia.
Bombus cullumanus, Cullum's bumblebee or Cullum's humble-bee. is a species of bumblebee found in Europe and Asia.
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 sitkensis, the Sitka bumblebee, is a species of bumblebee common in western North America from Alaska to California.
Bombus flavifrons, the yellow-fronted bumble bee or yellowhead bumblebee, is a species of bumblebee. It is native to North America, where it is distributed across much of Canada, Alaska, and the western contiguous United States.
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 ignitus is a species of bumblebee in the family Apidae. It is mainly distributed in Eastern Asia, commonly found in China, Japan and Korea. It is used in China and Japan commercially as a pollinator. B. ignitus is a eusocial insect with a queen that is monandrous: mating with only one male in the late summer before hibernating until the following spring. It builds its nest out of a mass of pollen and lays its eggs after completion. Due to numerous conflicts between queens and fertile workers, some surviving queens are badly injured, described by some as living corpses.
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.
