Killer Bee

What Is It?
The Africanized Honey Bee is a hybrid of one of the several European Honey Bee subspecies and the African Honey Bee.

Apperance:

Has a general appearance of the more temperamental European Honey Bee. However, they are slightly smaller, but only microscopic measurements in a laboratory would be able to distinguish between the two. They are robust, 3/4 of an inch in length, and are covered in fuzz. They are brownish in color with black stripes that aren't as distinct as those on wasps or hornets. They have four clear wings that are attached to the thorax, which is the middle section of the body. The six legs are also attached to the bottom of the thorax. The abdomen is larger than the thorax and ends in the stinger, and the head is smaller than both of the sections. The two compound eyes are large and bulbous and allow the Africanized Honey Bee to see ultraviolet rays, enabling them to fly at night. The queens are the largest bees in the social structure, followed by the drones and then the workers.

Behavior:
Africanized Honey Bees will attack when unprovoked, and they respond rapidly and in large numbers to disturbances that European Honey Bees would ignore. Like European Honey Bees, Africanized Honey Bees can sting only once; they deliver a venom identical to that of European Honey Bees. Both types of bee die shortly after leaving their stings and ends of their abdomen in their victim.


How They Got Here:
Honey bees are not native to the Western Hemisphere. European settlers brought most honey bees to the Americas approximately 400 years ago. However, European Honey Bees did not perform well in the tropical climate of South America. African Honey Bees were brought to the Western hemisphere in 1956, when the Brazilian government asked Dr. Warwick Kerr, a geneticist, to create a bee that could survive Brazil's tropical climate. The European Honey Bee had not been able to successfully withstand heat and predation. It was hoped that African Honey Bees, having proved themselves successful for millions of years in the tropics, could bred with the European bee. The goal was to create a bee which was gentle, yet successful in the tropics. However, in 1957, some of them got loose and set up housekeeping in the tropics of Brazil. They've been spreading ever since.

  1. It is interesting how the Africanized bees arrived in the U.S. The map you included is useful.
