Africanized "killer" bees look so much like regular honeybees that the only way to tell the two apart is by measuring their bodies. A dangerous stinging insect, Africanized bees have different wing measurements than honeybees.
Africanized bees have small colonies, so they can build nests in unique places. They have been known to live in tires, crates, boxes and empty cars. Worker bees gather both pollen and nectar from flowers to feed to the larvae and other members of the colony.
These bees defend their colony and attack when threatened. Africanized bee venom is no more dangerous than regular honeybees. However, these bees tend to attack in greater numbers, which poses a significantly greater danger to humans, especially those who are allergic to bee stings.
