Their main energies go into honey production for reproduction. They can easily survive outside of their nests, and frequently hang on the outsides of the nests. When Africanized honey bees developed in African Savannahs, they were constantly faced with the threat of destruction from predators. By selection, they succeeded in developing ways to survive these threats, both as individuals and as colonies. First, many of the returning foragers approach the hive and fly through the entrance at a high rate of speed.
Entrances are very critical areas which render foragers quite vulnerable.
By crossing this area quickly, they lessen the threat of being intercepted. Second, Africanized workers, while foraging, move in quick, furtive patterns, rather than the more steady, systematic movements of European bees. Their course is composed of quick darting movements which resemble those of yellow jackets, more than European honey bees. This pattern of movements makes their courses much less predictable and the chances of their being intercepted in flight become less. The third evolutionary advantage is the individual trait of immediately charging at a source of disturbance or threat.
