Unlike honey bees, bumblebees only store a few days worth of food and so are much more vulnerable to food shortages. Once they have collected nectar and pollen, bumblebees return to the nest and deposit the harvested nectar and pollen into brood cells, or into wax cells for storage. This scent mark deters visitation of the flower by other bumblebees until the scent disappears. In a few species of bumble bee, once it has visited a flower, it leaves a scent mark on the flower. While foraging, bumblebees can reach ground speeds of up to 54 kilometres per hour. Bumblebees will also tend to visit the same patches of flowers every day, as long as nectar and pollen continue to be available. They can visit patches of flowers up to 1 – 2 kilometres from their colony. Watch them in your garden – without disturbing them – and see how fascinating they are.īumblebees generally visit flowers exhibiting the bee pollination syndrome. It is very interesting to quietly observe a bumblebee at work. Bumble Bee Pollinationīumblebees are very important pollinators to many plants, flowers and fruit trees. The new queens will then find somewhere to hibernate during the winter, usually underground and emerge to find new nesting ground ready to start a new colony in spring. Just like social wasps, the bumblebee colony will die off at the end of summer. Like their relatives the honey bees, bumblebees feed on nectar and gather pollen to feed their young. The little food they do store is saved to feed the larvae and the egg-producing queen, or is used to survive cold, windy and rainy days. Bumble Bee Dietīumblebees do not store food (honey) to survive the winter. Honeybees, however, will only become active only when temperatures are above 15 degrees centigrade. Only in winter, when temperatures drop, they will go into hibernation. It is not dying or sick, but simply heating up its own body and they are unable to fly because of their wing muscle detachment.īumblebees keep a body temperature of 34 to 38 degrees centigrade, this is why it is common to see bumblebees even on colder and rainy days in the spring and summer. This is the reason you can sometimes find a motionless bumblebee on the ground or on a flower. By moving the detached muscles rapidly they produce their own body heat. They can detach the muscles which they use to move their wings. Just like mammals, bumblebees control their own body temperature. The poison they inject with a sting is harmless, but can be harmful to those allergic to wasp stings. Unlike the honeybee, the worker bumblebee does not leave its sting in your skin when it has stung you, this means it is capable of stinging you more than once. This position is a defensive position and they will feel threatened and prepare to sting. However, if you see a bumblebee lying on its back, then it is best not to touch it. You can take a bumblebee in your hand and as long as you do not treat it roughly, it will not sting you at all. The fat in the cells is used up during hibernation. Before hibernation, queens eat as much as they can to enlarge their fat body. The heart, like that in most other insects, runs down the entire length of the body. ![]() A male bumblebee has no stinger and therefore cannot sting.Ī bumblebee does not have ears, and it is not known whether or how a bumblebee can hear sound waves passing through the air, however they can feel the vibrations of sounds through wood and other materials. The female worker bumblebee has a stinger and is capable of stinging although they are never too willing to sting. Another obvious (but not unique) characteristic is the soft nature of the long, branched setae, called pile, that covers their entire body, making them appear and feel fuzzy. They can be seen bobbing around flowers and are a good indication that spring is here.īumblebees are usually a very distinctive black and yellow color, although they can be red and black or orange and black. We can recognise Bumble Bees from their very loud buzzing. (You might hear the bee on the left buzzing)! Most species of bumblebee live in colonies, but their colonies are much smaller than the honey bees or wasps who can have up to several thousand individuals, the bumblebee colony will only consist of around 50 – 150 individuals. Bumblebees are large, hairy bees and are close relatives of the well-known honeybee. ![]()
