In the part of body where the queens and workers bees have sting, bumblebee male have a sex capsule for mating. Male bumblebees can not sting, because they do not have sting.
Therefore, people who have an allergy to bee poison should be careful. However, some species of bumblebees found in the America (North and South) are more aggressive than the European variety. They sting in case of the danger to the nest. Bumblebees do not sting without a reason. Others have swelling and irritation which last for several days. Also pain seems stronger in certain parts of the body – the face and neck (for example).
Some think that bumblebee sting is less painful than a wasp sting, some say that it is also less painful than bee sting, others – more painful. This is due to the survival of the nest, so the queen bees and workers can survive for the reproduction and maintenance of the nest. Usually people think that bumble bees sting is stunted. But mammals have always been destroyers of bee hives and nests of bumblebees, but then why the bee sting has notch and why the stinging usually leads to the death of the bee. It is believed that the sting has evolved to be used against other insects – who do not have elastic skin. Some advise to pull the sting, others advise to squeeze the sting and poison under the skin. If the stinger with a bag of poison remains in your skin, the muscles contract, which leads to the injection of venom into the skin. So a stinger and poison bag of the abdomen tear off. The cause of death of a bee after it stings a man is that her sting has notch and the bee can not pull out the stinger. The differences between the stingers of honey bees and bumble bees Bumblebees can sting, at least the queen and the workers, and their sting is not barbed like bee sting.
