The cute bumblebee is one of the social insects. A cute bumblebee colony is depending Hummel from about 50 to 600 animals and a queen . The majority of animals are workers, in addition, the people also male drones and young, female queens. The cute bumblebee is very early in the year on the road, and it generates the necessary for flying body temperature by vibrations of the chest muscles. Thus, the queen fly at temperatures from 2 ° C and 6 ° C. workers from A honey bee for comparison needs a minimum temperature of 10 ° C. During feeding beautiful bumblebees can keep their body temperature constant.

Beautiful bumblebees are often seen having near the head bald, shiny spots on the body. The hair loss occurs when the entrance hole is so close to the nest. There are about 250 species of cute bumblebee, which occur mainly in the temperate and cooler regions of the northern hemisphere. Particularly rich in species are the bumble bees in Europe and Asia represented, they colonize almost the entire Eurasian land area north of the Himalayas.

Beautiful bumblebees are adapted to survive in a colder climate. The body is relatively large for an insect and is both long and dense hair, so the heat is retained properly. Therefore beautiful bumblebees come even on the cold tundra in the far north. The long hair is a disadvantage in hot weather, they must then rest a lot.

There are two groups of beautiful bumblebees, the best known are the species that make a nest like other moths such as ants, bees and wasps. The cute bumblebee nest remains generally smaller than that of other social hypnotherapy.

A cute bumblebee has a great body but relatively small wings. With the laws of aerodynamics could not explain long time that a cute bumblebee can fly. Research showed that beautiful bumblebees have a trick so they can take off anyway. The up and down movement of the wings turbulence created that provide an upward force causing the cute bumblebee, although he is actually too heavy, yet can fly. beautiful bumblebees so get extra energy from the way the wings move, and this phenomenon is studied in depth in aerodynamics will benefit out of it.

Beautiful bumblebees live like all other bees from nectar and pollen , the sugary nectar is the energy source of the cute bumblebee. There are cute bumblebee species that store the pollen in separate cells stock (pockets) and there are species such as the nature cute bumblebee that saving in casual empty brood cells. beautiful bumblebees up to 2 hours at a gathering pollen to a weight of 60% of their body weight. The pollen, the nectar and females using their front legs to a clump together and stick to their hind legs as transport to the nest. The hollow seemed the hind this is a bald spot, which is surrounded with stiff bristles. This place is called a corbicula.

In northern countries such as Norway and Sweden are beautiful bumblebees for pollination insects very important, because they are still flying at low temperature, in contrast to bees. In the southern countries such as France, with important for pollination. Netherlands is in between. In the Netherlands, about 29 different species of beautiful bumblebees, of which seven types of cuckoo beautiful bumblebees.

A cute bumblebee flies usually no more than 100 to 200 meters from the nest. The nectar is collected nectar in the stomach, which can expand many times. After leaving the nest the males of many cute bumblebee species show a typical behavior. They fly the same route with a radius of about 150-200 meters where they put off a fragrance that attracts young queens.

The nests of beautiful bumblebees never reach the size of the honeybee. When they arrive at a flower can extract nectar using their long tongue or gloss . Some beautiful bumblebees turn to pierce the base of the corolla of a flower where the nectar is hidden, so do not benefit because it has no place flower pollination. cute bumblebee’s body is covered in pollen, in part by its hairiness and in part by its electrostatic charge. This pollen brush and transfer it to the baskets corbiculae pollen or hind paws after moistening with a mixture of saliva and nectar. cute bumblebee returns to the nest and deposit their load of pollen and nectar into receptacles.
