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 impatiens, the common eastern bumblebee, is the most commonly encountered bumblebee across much of eastern North America. [3] They can be found in the Eastern temperate forest region of the eastern United States , southern Canada , and the eastern Great Plains . [ 4 ]
By monitoring the levels of the honey pots a bumblebee colony can either up or down regulate the number of bees out foraging. [3] Lab experiments by Anna Dornhaus and Lars Chittka in 2005 showed evidence of this up or down regulation by monitoring the activity level of the hive after the addition of 'nectar' to the honey pots.
Nectar robbers vary greatly in species diversity and include species of carpenter bees, bumblebees, stingless Trigona bees, solitary bees, wasps, ants, hummingbirds, and some passerine birds, including flowerpiercers. [1] Nectar-robbing mammals include the fruit bat [2] and Swinhoe's striped squirrel, which rob nectar from the ginger plant. [3]
Furthermore, bumble bees are predated on by birds for food. Foragers are frequently predated by invertebrates. Crab spiders and cryptically colored ambush bugs ambush bees at flowers to catch them. Robber flies resemble bumble bees and clasp the bumble bees, insert them with enzymes, then eat their internal organs.

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 ]
They usually visit consecutive flowers in one direction and do not return to previous flowers. They tend to go to areas that are rich in resources and usually do not visit these areas again once the bees deplete the resources. [10] Instead, it has been found that B. terricola expend energy to fly to new locations of food sources.
