What are the types bees?

I just want to know the types of bees and what there sting doesWhat are the types bees?
All bees belong to only one species. It is a common misunderstanding to believe that so called Africanized bees are of a different species. Anyway, the stinger is a harpoon shape. The venom sack is filled with a venom that is produced by specialized glands (the venom is actually a protein). When the bee feels the safety of the colonies is in jeopardy it will sting. The little harpoon penetrates the skin and the bee flies away. The yellow part that sticks out of the skin are actually the bees inerts (guts). The churning of the digestive track squeezes the venom sack introducing more venom into the victim. The bee dies soon after (after all it just ripped out its stomach).





Do understand that bees don't just sting when they want to. They only sting if all other attempts fail. They sting to protect the hive and queen.What are the types bees?
There are almost 20,000 species of bees. Some don't even sting and I don't believe that males or drones ever sting. The stinger is a modified egg layer and is used to inject a protein venom into the target. A honey bee has a barbed sting that will work its way into a wound and continue to pump venom. The bee will pull it out and die after stinging a mammal.
