Honeybee Facts


Honey bees are complex, social insects. There are three types of bees in a honey bee colony: the queen, female worker bees, and male drones. Worker bees typically live only 4-6 weeks in spring or summer but up to 140 days in the winter. Queens live 2-5 years and drones usually last 60 days at most.

The Queen Bee

The queen bee spends her life safely tucked away in the hive. A healthy, well-fed queen lays up to 2,000 eggs per day, and young worker bees act as her attendants, bringing her food and disposing of her waste.

If the queen is injured or killed, or her egg laying decreases, a process called supersedure takes place. Worker bees choose certain eggs and prime them to turn into queens. They feed these young nothing but royal jelly and after a week, the potential queens emerge from their beeswax-sealed cells and fight each other to the death until just one remains. The winner will then sting to death any potential queens still sealed in their cells, after which she mates with a number of drones in the air, an endeavour known as the “maiden flight.”

The new queen returns to the hive to lay her eggs after a few days. The old queen, if she is still with the hive, is usually killed by the worker bees. They do this by forming a tight ball around her, causing her to die from overheating. If the workers don’t kill her, the new queen will.

New queens may also be raised if a colony becomes so large and successful that a portion of it decides to split off and establish a new hive elsewhere. In this case, many of the workers leave with the old queen and the remaining workers raise a new queen.

The process of finding a new home is relatively democratic. Worker bees acting as scouts fly ahead and identify potential new homesites, after which they return and do dances to tell other bees about the locations they’ve found. The most enthusiastic dances draw the most interest, influencing additional scouts to check out the new sites. If they’re suitably impressed, they’ll come back and dance along with the bees that recommended the site they like.

Several groups of bees may dance on behalf of a number of different locations. The group that gets the most converts the quickest will usually get its way. Researchers have found that 15 bees in a group tends to be the magic number for convincing the rest to move to a specific location.

The Worker Bees

There are typically 20,000-60,000 worker bees in a honey bee colony and these bees don’t reproduce unless the colony has lost its queen or is headed by a failing queen. In such cases, the eggs they lay develop into drones, though in some species, such as the Cape honey bee (Apis mellifera capensis), worker bees can produce female workers.

From 1-12 days of age, worker bees act as nurses, feeding the brood. At 10-20 days of age, they build combs, clean house, accept pollen and nectar from adult foragers, act as undertakers, and guard the hive. At about 20 days of age, they are promoted to foragers, collecting not only nectar and pollen but also water and plant resin.

To create a teaspoon of honey requires about 12 worker bees, each visiting 2,600 flowers, travelling a collective 850 miles. When a worker bee finds a good nectar source, after stocking up, she’ll come back to the hive and do a little dance to indicate the location to other bees. When the source is close by, she does the round dance, which comprises narrow circles and may include offering samples of the nectar to onlookers. If the source is more distant, the more complicated waggle (figure-eight) dance is used.

During the coldest months, worker bees huddle together in the hive, generating heat by flexing their flight muscles. Wintering worker bees take turns acting as insulators on the outside of the bee cluster, with those at the periphery moving toward the center when they need to warm up. During this time, they live off the honey they have stockpiled during the warmer months.

The Drones

Drones, or male bees, are larger than worker bees, and lack stingers. Drones have no purpose other than to mate with passing queens. They keep themselves in shape for these midflight matings by engaging in practice flights, but otherwise, contribute nothing to the hive. They eat the pollen and nectar collected by the female workers, but don’t collect any themselves.

Despite this life of leisure, there is a downside to being a drone. When he does mate with the queen, his genitals snap off and he dies. Also, unmated drones are considered a drain on the hive during the cold season, so any still alive when fall rolls around are viciously attacked by worker bees and, if they manage to survive the brutal onslaught, are shoved out into the cold to starve.

Bees Used for Landmine Detection

Scientists have developed a safer and less costly method of landmine detection using honey bees.

Landmines severely injure or kill an estimated 20,000 people each year, and of these victims, 30%-40% are children. Traditional landmine detection methods are problematic for a number of reasons:

    • They present extreme risks to humans and the sniffer dogs that accompany them.
    • Dogs require time-consuming training and work less effectively with handlers other than their masters.
    • It would take around 450 years using current methods to neutralize all hidden landmines.
    • Traditional landmine detection methods are very expensive.

To address the problems associated with traditional landmine detection methods, an innovative team of scientists has come up with a way to detect landmines without risking the lives of people or animals.

Bees have an acute sense of smell, which enables them to find food. Taking advantage of this trait, a group of scientists, led by Jerry Bromenshenk and Joseph Shaw, have conditioned bees to interpret the scent of chemicals used in explosives as food. The association is established by adding traces of explosive by-products to bee feed.

Once the bees have been conditioned, the hungry swarm is let loose and tracked using lidar, a type of remote sensing that uses laser light. This technique is similar to sonar, which uses sound, and radar, which uses radio waves for tracking purposes. This method provides a number of advantages:

    • Bees are too light to detonate mines.
    • Bees don’t favour any particular master.
    • Conditioning takes only a couple of days.
    • Costs are lower.
    • Local bee keepers are provided with additional employment.
    • Encouraging bees to visit helps to reestablish agricultural systems in war-torn regions, as approximately 80% of crops depend on them for pollination.

Conditioned bees have shown a 97% or greater accuracy in finding landmines. Using similar conditioning methods, bees can also be used to detect bombs, drugs, and decomposing bodies. Although promising, the honey bee technique is subject to a couple of limitations:

    • Bees won’t fly during bad weather, in very cold temperatures, or at night.
    • Lidar only works effectively on flat landscapes.

Work is ongoing to improve the laser technology. In the meantime, other potential solutions have been explored, such as attaching very small radio-frequency ID tags to bees or painting them fluorescent colours to make them more visible.
