Bees are part of a group of insects known as Hymenoptera which also includes ants, wasps, and sawflies. Bees are found on every continent of the Earth except Antarctica. There are about 20,000 different species of bees around the world. 4,000 of those species live in the United States. Honeybees and bumblebees are probably the best-known.

The honey bees in the United States were brought here when Europeans migrated here in the 1600s and 1700s. Other bees, such as bumblebees and carpenter bees, are native to the U.S. Bees are very beneficial insects that are necessary for the pollination of many plants.

Most bees live in communities known as colonies. Sometimes they build their hives in trees or abandoned rodent holes. Some kinds of bees actually dig holes into the ground to live or make their homes in small spaces in fences or rocks. People have kept bees and used their honey since ancient times. These days, people raise huge honey bee colonies by providing spaces especially for the bees to build their hives. They then harvest the wax and the honey to sell.

The Queen, the Drones, and the Workers

Honeybees and bumblebees have very organized communities called colonies. Each hive has only one queen. She became a queen when her larvae body was selected out of all the other larvae and she was fed something called royal jelly — a substance secreted by the worker bees that care for the larvae. Her body is now larger than all of the other types of bees. Her only job is to lay eggs. This starts in the spring and can continue until fall. She lives to be about five years old. Queens rarely leave the nest.

The drones are the only males in the hives and do no work except feed themselves. Their only job is to mate with the queen. Then they die. After the egg-laying season is over, those who didn't mate are forced to leave the hive.

Workers are all female and do all of the work within a colony. Workers create the hive from wax that they produce from their bodies. They gather all of the nectar used to make honey. They care for the eggs and the larvae, raise the young bees, clean the nest, get rid of dead bees and other debris, defend the nest, and feed the queen. A honey bee colony may have as many as 50,000 workers. Bumblebee colonies are much smaller.

Bee Anatomy

Bees do not have bones. They have an exoskeleton; a hard outer shell that gives them structure, protection, and support. The exoskeleton is covered in several kinds of hair. Like other insects, the body of a bee is divided into three body regions: head, thorax, and abdomen.

Bees have a head with a pair of antennae and five eyes. Three of the eyes are simple eyes and work similarly to our eyes. The other two are compound eyes; each compound eye has 150 seeing parts. A proboscis is a tube-like straw which allows a bee to collect nectar. The thorax is the middle section of the bee's body, between the head and the abdomen. The thorax is similar to the chest of a human. Bees have four wings — two in the front and two in the back. The arrangement of the wings gives them special flying ability. Their legs have hairs that act like a pollen-carrying basket. In the abdomen, they have a honey stomach for storing the nectar that they collect until they return to the hive. At the very end of the abdomen is the stinger, which is attached to very strong muscles, and the venom bulb.

Making Honey

When flowers begin to bloom in the spring, the worker honey bees are attracted to them because of their color and fragrance. They love to drink the nectar the flowers contain. Their hive is made of little rooms or combs. The nectar is deposited in the combs later when the worker bees return home. They fan the combs with their wings to help water evaporate from the nectar. This thickens the nectar into honey. When the honey is ready, they cover the comb with wax to protect it.

Today's bees have been bred to be far more efficient than bees of old. This allows them to make far more of the honey than they need. Beekeepers take the excess and leave what the bees need to survive. Honey bees use the honey for the same reason we do. They eat it.

While the worker bees are crawling around in the flowers drinking nectar, they are also doing a huge service to the plant world. Pollen is a fine, powdery substance that plants use to create fruit and seeds. It grows on the anther of a flower. But it needs to be deposited on the pistil of the flower for the flower to make its fruit. The plant is unable to perform this function on its own. When the bees crawl around inside the flowers, they gather pollen on their legs — lots of it. Some of the pollen is then transferred from one flower to the pistil of the next flower. The pollen then makes its way down into the fruit-making part of the flower. There, the pollen combines with the material inside the ovary to grow into a fruit filled with seeds.

Bee Dances

Bees communicate through two dances that they perform to tell other bees about the location of nectar. The first dance is known as the "waggle dance" and involves waggling their tails and turning in a figure eight. It is used to point out the location of food more than 35 yards away from the hive. It is so specific and accurate that scientists have actually been able to translate the movements and actually "read" the directions the bees are giving. The "round dance" is for telling about food less than 35 yards and is done after sharing some of the nectar with the other bees. They do not get direction from her about location, but they can use the scent of the shared nectar to help them find it.

You can watch bee dances from NOVA.


bee stinger

Bees do not sting as an aggressive act. They sting to defend their hive. Drones do not have the ability to sting. Workers are primarily the bees that sting. Their stinger has a barb or hook at the end of it which causes it to remain in the skin of the victim. When the bee tries to fly away, the stinger is pulled off of the worker and they subsequently die. The queen can sting, but since she rarely leaves the hive, it is uncommon for her to do so.

Stingers inject venom, and the venom sac remains attached even after the bee has flown away. Removing the stinger is the best defense against the venom. The venom is usually only an irritant. Only people with bee sting allergies ever get sick or die from a sting.

Bee Talk

Besides dancing, bees also communicate by buzzing, by emitting chemicals known as pheromones, and by sharing food — an activity called trophallaxis. The queen uses pheromones to keep order in her hive. Pheromones are also exchanged during the passing of food from one bee to another. The bees do this just before the round dance and when they feed their young or the queen. They are very complex, and it seems, very intelligent creatures.

Bees also use pheromones to create a swarm. When a hive becomes too large for the queen to accommodate all of the worker bees, a new queen will be created. The old queen will produce pheromones to gather a portion of the hive together just before going off to create a new hive. The bees all fly around the queen looking for a new place to nest. The new queen then takes over in the old nest to control her hive.

Bee Concerns

Africanized Honey Bees: In the 1950s honey bees were brought from Africa to Brazil in hopes that they could be bred with the European bees that lived there. The goal was to create a better kind of honey bee that could make more honey. These Africanized bees spread throughout South America and parts of North America. They have been given the name "killer bees" because they are more aggressive and more likely to sting than the common European honeybee. However, like other honey bees, they are only defensive at the nest.

Missing Bees: Many native plants and food crops require bees for pollination. Throughout the world, bees pollinate more than three-fourths of the food crops that people eat. Different species of bees pollinate many of the different plants that make up our food supply. One out of every three bites of food in the human diet is a result of bee pollination! Think about a hamburger: without bees, there would be no ketchup, mustard, tomatoes, lettuce, pickles, onions, or even cheese which comes from cows who eat bee-pollinated alfalfa. And the chips or fries come from bee-pollinated potatoes. Bees also pollinate plants that provide food and habitat for all types of animals. Bees are a critical part of the ecosystems that support life.

So it is a concern that American and Canadian honey bees, as well as other kinds of native bees, have been declining in numbers over the past decade. Scientists don't know the exact reason, but it is probably a combination of factors: parasites, pesticides, infections, bee stress, and loss of important bee habitat. Today, scientists are working to collect more data about bees so they will know better how to help their survival. You can help bees by planting a variety of flowering plants, reducing pesticide use, and providing nesting habitat. Learn more about helping to protect bees.

Top 10 Questions

May 2013

Thanks to Dr. Ron Bitner, entomologist and vintner, Caldwell; and Kirk Tubbs, berry farmer and beekeeper, Twin Falls for the answers.

  1. Why do bees sting?

    Honey bees are really small and they have to protect their winter food. Their stinger is their way of defending their food. They've evolved in a way to protect themselves against something big like a bear. Bees don't like to sting unless they have to because when they sting, they die. It's something they do only if they absolutely have to. When you step on a bee, it stings as it feels it's going to die. (From Ledger at Kamiah Elementary School in Kamiah)

  2. Why do bees pollinate flowers?

    The pollen is the protein source for the bees to lay their eggs on. It's a benefit to the flower because bees move pollen from flower to flower and this lets the seeds develop. (From John at Dalton Elementary School in Dalton Gardens)

  3. Why is there a queen bee?

    The queen bee is the one that helps regulate the hive. She has her smell, her pheromones, that calm and regulate activity. She lays all of the eggs and without her, the hive would cease to function. The individual bee is not as important as the colony. Bees work together in a group and each bee is important to the group, but each bee, by itself, couldn't survive. (From Molly at Berkswich Primary School in Staffordshire, England)

  4. Why do bees have four wings?

    In the insect world, wings are used for flight. With bees, the four wings operate a bit like a helicopter. The wings allow them to go where they need to go. Up, down, sideways . . . they can explore the flowers, as they need to. (From Bridget at Dalton Elementary School in Dalton Gardens)

  5. Do bees have a favorite food?

    Bees can tell how sweet something is when they taste it. If they find a fruit or flower with a nice nectar, they will go back and tell the rest about it. So, they tend to go to the richest nectar source, or whichever has the highest sugar concentration. (From Jasmine at Berkswich Primary School in Staffordshire, England)

  6. Why do bees live in hives?

    The hive is just a place to protect the bees. Bees live together in a colony, a big group. The hive is a place to protect them as they work together. (From Bogey at Kamiah Elementary School in Kamiah)

  7. Are bees intelligent and do they play?

    There are different forms of intelligence. We regard the honey bee as intelligent because of her behavior. She can learn a lot and her workers can learn a lot in addition to giving directions. They have their own language. With solitary bees, you have hard-working female bees pollinating the flowers, and the males are flying around and checking things out. Bees are very smart. They figure things out very quickly. (From Alex at Berkswich Primary School in Staffordshire, England)

  8. How many different types of bees are there in the world?

    In the world, there are 20,000 different kinds of bees. There are 10 different kinds of honey bees in the world, although we just have one kind here in the United States. There are around 4,000 different kinds of bees in the western states. In Idaho alone, we have several thousand different kinds of bees. (From Millie at Basin Elementary School in Idaho City)

  9. How do bees buzz?

    The buzz you hear is the sound of their wings. They vibrate their wings and we hear that sound as a buzz. Each insect and how they move their wings has a slightly different sound. (From Freya at Berkswich Primary Elementary School in Staffordshire, England)

  10. Why are bees covered in hair?

    The hair helps them collect pollen. The pollen sticks to the hair, and when they go from flower to flower it is transferred around. Hair also helps them to haul pollen back to the hive. (From McKenzie at Dalton Elementary School in Dalton Gardens)
