Salivary glands in the head secrete saliva which is mixed with the nectar and pollen. Saliva is also mixed into the nest materials to soften them. The fat body is a nutritional store; before hibernation queens anatomie de l ongle as much as they can to enlarge their fat body, and the fat in the cells is used up during hibernation.


Like all bee tongues, the bumblebee tongue the proboscis is composed of many different mouthparts acting as a unit, specialised to suck up nectar via capillary action.

At rest or when flying the proboscis is kept folded under the head.


The abdomen is covered with dorsal tergites and ventral sternites. Wax is secreted from glands on the sternites. The brightly-coloured pile of the bumble bee is a form of aposematic signal.

Depending on the species and morph, these colours can range from entirely black, to bright yellow, red, orange, white, and pink. Thick pile can also act as insulation to keep the bee warm in cold weather.


Further, when flying a bee builds up an electrostatic charge, and as flowers are usually well grounded, pollen is attracted to the bee's pile when it lands. When a pollen covered bee enters a flowerthe anatomie de l ongle pollen is preferentially attracted to the stigma because it is better grounded than the other parts of the flower.

A bumblebee anatomie de l ongle not have ears, and it is not known whether or how a bumblebee could hear sound waves passing through the air, however they can feel the vibrations of sounds through wood and other materials. A few species Bombus polaris and B.

anatomie de l ongle One reason for this is that bumblebees can regulate their body temperature, via solar radiation, internal mechanisms of "shivering" and radiative cooling from the abdomen, called heterothermy. Other bees have similar physiology, but it has been best studied in bumblebees.

These colonies are usually much less extensive than those of honey bees. This is due to a number of factors including: Often, mature bumblebee nests will hold fewer than 50 individuals, and may be within tunnels in the anatomie de l ongle made by other animals, or in tussock grass.

Bumblebees sometimes construct a wax canopy "involucrum" over top of their nest for protection and anatomie de l ongle. Bumblebees do not often preserve their nests through the winter, though some tropical species live in their nests for several years, and their colonies can grow quite large, depending on the size of the nest cavity.

The last generation of summer includes a number of queens who overwinter separately in protected spots.

Oh no, there's been an error

The queens can live up to one year, possibly longer in tropical species. Bumblebee nests are first constructed by over-wintered queens in the spring, in temperate areas. Upon emerging from hibernation, the queen collects pollen and nectar from flowers and anatomie de l ongle for a suitable nest site.

The characteristics of the nest site vary among bumble bee species, with some species preferring to nest in anatomie de l ongle holes and others in tussock grass or directly on the ground.

Once the queen has found a site, she prepares wax pots to store food and wax cells into which eggs are laid.


These eggs then hatch into larvae, which cause the wax cells to expand isometrically into a clump of brood cells.
