These differences in ability may have evolved as different types of bees developed specific roles within the colony. Other experiments have indicated that body size is an important factor in how bumblebees pollinate. It appears that size affects the frequency of a bee's visits to flowers, as well as its pollination skill.
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 .

Bombus terrestris, the buff-tailed bumblebee or large earth bumblebee, is one of the most numerous bumblebee species in Europe. It is one of the main species used in greenhouse pollination , and so can be found in many countries and areas where it is not native, such as Tasmania . [ 2 ]
Bombus sonorus, commonly known as the Sonoran bumble bee, is a species of bumble bee in the family Apidae.It is found in Mexico and southwestern North America. [1] [2] [3] Although it has often been categorized as a subspecies of Bombus pensylvanicus [4], it is has since been shown to not hybridize with B. pensylvanicus over a broad area of geographic overlap, confirming its status as a ...
Bombus affinis, commonly known as the rusty patched bumble bee, is a species of bumblebee endemic to North America. [3] Its historical range in North America has been throughout the east and upper Midwest of the United States, [4] north to Ontario, Canada, where it is considered a "species at risk", [5] east to Quebec, south to Georgia, and west to the Dakotas.
