Differences Between European and African Honey Bees1

M. K. O'Malley, J. D. Ellis and C. M. Zettel Nalen2

African honey bees and European honey bees are the same species (Apis mellifera), but the two are classified as different sub-species. European honey bees were first introduced to the Americas in the 1500s by European explorers. For centuries, European honey bees have been selected by beekeepers for their robust honey production and storage behavior, their reduced regular swarming (colony splitting) tendencies, and their gentleness. The African honey bee (Apis mellifera scutellata) was brought to Brazil in the 1950s in an effort to increase honey production. However, 16 queens were accidentally released and thrived in Brazil's native environment. Since then, African bees have spread throughout South America, Central America, and into the United States. The African honey bee is considerably more defensive than its European cousin. Consequently, it is important to understand key differences between the aggressive African bee and the docile European honey bee. Please note, the term "Africanized" is generally applied to any progeny resulting from matings between European and African bees.

Hive Defense and Stinging

Unlike wasps and hornets, honey bees can only sting once, and will die shortly afterward. Stinging is often a last resort in hive defense.

The venom of the African honey bee is no more potent than that of the European honey bee. For a fatality to occur from venom toxicity, it normally would take about 10 stings per pound of body weight, from either a African or European honey bee. The main difference between the European and African honey bee is its defense response; an African honey bee colony, if disturbed, will send more guard bees to sting, and will pursue for a longer distance and stay agitated for a longer period of time, than a European honey bee.

Swarming and Absconding

Swarming is a natural occurrence when the colony gets too large and resources are abundant. The colony rears a new queen and the hive splits. Absconding occurs when resources are scarce or there is a threat to the hive. The entire colony will abandon the hive for a new location. For more information about swarming, see the Resources section for Frequently Asked Questions about the African honey bee in Florida.

Selection of Nesting Site

Because Africanized honey bees swarm more often, fewer individuals are involved in each swarm, meaning they do not require a large cavity to build a nest. Africanized bees are often discovered in water meter boxes (Figure 4) and other man-made cavities, whereas European honey bees need a larger volume nesting site, and tend to nest in hollowed tree cavities (Figure 5).

Table 1. 

European Honey Bee

African Honey Bee

May send out 10-20 guard bees in response to disturbances up to 20 feet away (Figure 1)

May send out several hundred guard bees in response to disturbances up to 120 feet away (Figure 2)

Once agitated, will usually become calm within 1-2 hours

Once agitated, may remain defensive for days

Disturbed colony may result in 10-20 stings

A disturbed colony may result in 100-1000 stings

Table 2. 

European Honey Bee

African Honey Bee

Swarm 1 or 2 times per year

Can swarm 10 or more times a year

Swarms are larger and need larger volume to nest

Swarms contain fewer individuals, and therefore a much smaller cavity is needed (Figure 3)

Rarely abscond (or completely abandon nest) from nesting location

Abscond often and relocates to more suitable nesting locations

Table 3. 

European Honey Bee

African Honey Bee

Nest in large cavities, around 10 gallons in size

Nest in smaller cavities, 1 to 5 gallons in size

Typically nest in dry, above ground cavities

Will nest in underground cavities with a high moisture content

Nest in protected locations, rarely exposing the nest (Figure 5)

Will nest in exposed locations, (e.g. hanging from a tree branch) (Figure 6)

Due to larger colony size, nests are often easier to detect

Due to smaller colony size, nests often go undetected until disturbed
