  Bumblebee - Wikipedia, the free encyclopedia
The bumblebee is a flying insect of the genus Bombus in the family Apidae.
Like the common honeybee, of which it is a relative, the bumblebee feeds on nectar and gathers pollen to feed its young.
Bumblebees are social insects that are characterized by a fl and yellow striped body, a commonality among the majority of the species of Bombus; however, some species are known to have orange or even red on their bodies.

 Bombus lapidarius
Bombus lapidarius is probably the most easily recognised species.
The workers have the same colouring as the queen, but they are much smaller; some of the early workers are no bigger than house flies.
It shows that a bumblebee nest is not the tidy, precise affair that a honey bee hive is. Bumblebees commonly use an old rodent nest.

 Bumble Bee
The native-to-Iowa bumble bee species, Bombus bimaculatus, has been used in pollinator studies at the Station since 1994.
New queens from these lab reared colonies are produced and mated, however, successfully diapausing these queens has not been entirely successful and is an area where further research is being practiced.
Bombus bimaculatus is a long-tongued species of bumble bee.

This, according to Katayama (1996), was provided by the low foraging activity since after the death of the queen most workers tended to stay in the nest to obtain the position of predominant egg-layer.

 Gordon's Social Bees Page
Bumble Bees are the least advanced of the major groups of Eusocial Bees and their foraging is limited by the fact that they have not evolved any means of communicating information reguarding utilisable resources.
The social parasite Queen waits until her host has built the nest and raised a few workers, then she sneaks into the nest, generally she is discovered and attacked by the workers, however she has a stronger, thicker cuticle than her hosts and often remains undeterred by their attacks.
Bumble Bees are the only group of eusocial insects to initiate nectar theft, they do this by biting a hole in the base of the nectar spur or some other suitable part of the flower in order to allow themselves access to nectar from flowers they would otherwise be unable to get the nectar from.

 Action plan for Bombus humilis
Bombus humilis is a brown carder bumblebee which makes its nest on the surface of the ground at the base of long vegetation, often under accumulated plant litter.
Non-native forms of Bombus used for pollination in greenhouses may be a threat, but this requires further investigation.
Encourage further research to identify the extent to which the introduction of non-native forms of Bombus used for pollination in greenhouses may be a threat to the species.

 Results from BUMBLEBEE FORAGING PREFERENCES: DIFFERENCES BETWEEN SPECIES AND INDIVIDUALS   (Site not responding. Last check: 2007-10-09)
The bees marked in August were workers and males, although it is possible that newly emerged Bombus pratorum queens were marked, as there is little difference in size between them and larger workers of the same species.
On the 24th no Bombus pascuorum were seen the entire day, whereas on the three previous days they had been foraging on Vicia sepium.
Preferences are shown, and those of Bombus pratorum and B pascuorum for Centaurea hypoleuca are quite strong, but the number of observations for all species is quite small.

 Vestal cuckoo bee - Bombus vestalis: More Information - ARKive
Until recently, cuckoo bumblebees were once considered to belong to a separate genus (Psithyrus) in recognition of their distinctive appearance and their behaviour as parasites in the colonies of other bumblebees.
Lately, experts have, by and large, agreed that all bumblebees belong to a single genus, Bombus, with Psithyrus as a subgenus (3).
Bombus terrestris (the great earth bumblebee) is the only known host of Bombus vestalis, and the cuckoo’s distribution reflects the predominantly southern distribution of its host in Britain (4) and, presumably also throughout its palaearctic range (2).

 Changes to plant-pollinator associations caused by bumblebees   (Site not responding. Last check: 2007-10-09)
The complete genus Bombus was nominated, however, the only species that currently occurs in Australia is the Large Earth Bumblebee, Bombus terrestris.
Further, given Australia's strict importation and quarantine regulations, under which applications for import of exotic species must prove minimal environmental impact, listing an exotic species which is not present in Australia as a key threatening process would not further the aims of the EPBC Act in protecting Australian biodiversity.
Bombus terrestris densities can be highly variable; and the adoption of a precautionary approach, under criteria (b) may seem justified, as the process could cause listed vertebrate and plant species to become eligible for listing in a higher category.

 Vestal cuckoo bee - Bombus vestalis - ARKive
Lately, experts have, by and large, agreed that all bumblebees belong to a single genus, Bombus, with Psithyrus as a subgenus.
Cuckoo bees are similar in appearance to bumblebees, but they have a softer ‘buzz’, indeed Psithyrus means ‘murmuring’ as opposed to ‘Bombus’, which means ‘booming’.
Other differences include the lack of pollen baskets on the legs and a sparser coat of hairs, through which the shiny fl cuticle can easily be seen.

Qinghailaelaps marmotae, the type species of the genus Qinghailaelaps Gu and Yang, 1984 has been described from Marmota himalayana (Hodgson, 1841) (Rodentia: Sciuridae); another species of this genus, Qinghailaelaps gui Bai, 1992, was found phoretic on a bumblebee (Bombus).
Because the genus-level characters of Qinghailaelaps correspond to those of Pneumolaelaps, we consider the former as a junior synonym.
