Honey Bee Anatomy: Hairy Eyeballs and Other Amazing Facts

Honey bees are greatly admired by Ms. Giordano. They are a favorite topic for her writing and public speaking.

The more I study honey bees, the more I appreciate how amazing these little creatures are.

There are roughly 20,000 species of bees, but there are only seven species that are categorized as honey bees (in the genus apis). The European honey bee, Apis mellifera, is the most widely known because it has been domesticated for honey production and crop pollination.

What Are the Three Main Parts of a Honey Bee’s Body?

Like all insects, a honey bee’s body is composed of three main parts—the head, the thorax, and the abdomen. There is a “waist” where the thorax joins the abdomen. The abdomen contains bands of yellow-orange and black stripes and ends in a pointy tip.

Just How Small Are Honey Bees?

A honey bee is a tiny insect. The females—the worker bees that do the foraging—are 12 to 15 mm long (about ½ an inch long). They are the smallest of the three kinds of honey bees—the drones (male bees) are slightly larger, and the queen bee is larger still.

A worker bee weighs only about 100mg (150th of an ounce). It is so light that it can walk on your bare skin, and you may not even feel it.

What Is the Size of Their Brain?

A honey bee’s brain measures just one cubic millimeter—about the size of a sesame seed. Although tiny, it is large compared with the brains of other insects.

Their brains are about ten times denser than a mammal's brain which may explain why, despite their tiny brains, they are very smart.

Does a Honey Bee Have Hairy Eyeballs?

They have five eyes, two large compound eyes, one on either side of their head and three smaller eyes, called ocelli, at the top of their heads.

The compound eyes have thousands of lenses (ommatidia) which most likely give them a pixilated view of the world. Honey bees can see light, motion, and colors.

A short hair grows in the intersections of the compound lenses of the eye. These hairs are believed to detect wind direction and may be used by the bees to stay on course in windy conditions.

The ocelli serve as a kind of navigation system allowing the bee to triangulate its position relative to the sun and thus to find its way home.

Note the large compound eye and the bent antennae.

How Do Honey Bee Antennae Function?

The antennae are extremely sensitive allowing the bee to feel, smell, and even taste its surroundings. Unlike other bees which have straight antennae, the antennae of honey bees are bent at a 90 degree angle, allowing the bee to rotate its antennae at the “joint” increasing the area it can come into contact with.

How Does a Honey Bee Use Its Mouth-Parts?

The mouth (mandible) is attached to powerful muscles, making it a strong weapon against insects like mites or other creatures which try to invade the hive.

The mandible is also used as a cutting tool—it is used to create the honeycomb by shaping the beeswax into neat hexagonal cells.

It can also be used as a cleaning tool to pick up and remove debris from the hive.

The mouth contains a kind of tongue called a proboscis. It is a long coiled hollow tube that works like a drinking straw. The proboscis is unfurled to reach deep within a flower to obtain the nectar. It then curls back up into the mouth until the bee reaches the next flower. It is also used for sucking up drinking water.

And, finally, the mouth is used for eating bee bread—a mix of fermented honey and nectar that is produced by bees within the hive.

How Do They Breathe?

They breathe through holes along the sides of their thorax and abdomen called spiracles. They are lined with muscles which are used to close and open the breathing holes. The spiracles are attached to trachea, breathing tubes.

How Many Stomachs Does a Honey Bee Have?

They have a crop or “honey stomach” above the true stomach, the one used for digestion. When the bee is foraging in the fields, she stores nectar in her honey stomach. There is a muscular valve called the proventriculus between the honey stomach and the true stomach. The bee closes this valve to prevent the nectar from passing into the stomach.

Once the bee has returned to the hive, she ejects the contents of the honey stomach through the mouth.

There are some who jokingly refer to honey as “bee barf.” This is not true because none of the nectar used to make honey comes from the stomach used for digestion.

A honey bee uses her tarsal claws to cling to the stone edge of a bird bath.  Note the translucent wings.

How Many Wings Does a Honey Bee Have?

They have two pairs of transparent wings—a larger fore wing and a smaller hind wing—on each side of their thorax. The fore wings and hind wings move together when the bee is in flight, allowing her to fly quite fast (12 to 20 mph).

Do Honey Bees Have Knees?

Like all insects, they have six legs—the first pair of legs is shorter than the rear legs.

Each leg is made up of five segments separated by joints. The closest segment to the body, called the coxa, is followed in descending order by the trochanter, femur, tibia, and tarsus.

Have you heard the expression the “bee’s knees”? Bees don’t have actual knees, but they do have joints on each of their legs, connecting each of the leg segments. So that is four joints per leg times six legs for a total of 24 “knees.”

How Do They Clean Their Antennae?

The first pair of legs includes an antennae-cleaner—a pointy little spur located at the fourth joint. When the antennae get covered with too much pollen, the bee inserts an antenna into this joint, closes the hook to the joint, and rubs the antenna clean by sliding it through the gap created by joint and hook.

What Are Pollen Baskets?

The two hind legs each contain a “pollen basket” (corbiculae), little sacs made of long stiff hairs that curve around a flat section of the bee’s rear legs. The bee stuffs pollen grains into these baskets using the stiff hairs on the back of her other legs to scrape the pollen into them and pack them full.

The baskets are transparent so the brightly-colored pollen can be easily seen. These baskets are emptied when the bee returns to the hive. The bees use the pollen to make bee bread. (Pollen contains the protein, lipids and nutrients bees need.)

You can plainly see the full pollen-basket.

Do Honey Bees Have Claws?

They have claws at the tips of their feet. This allows them to stand on rough surfaces like bark without falling off. But their feet also have soft pads which provide enough friction to allow them to stand or walk on smoother surfaces. These pads also provide the honey bee with information about the surface it is walking on.

Why Are Their Bodies Furry?

They don’t have fur exactly, but they do have a lot of hair on their bodies and legs. Nearly their entire body is covered with branched hairs, like the needles on the branch of a spruce tree.

Pollen clings to their hairy bodies. A honey bee uses her hairy front and middle legs like brushes to comb the pollen off her body and pack it into the pollen baskets on her rear legs.

And Lastly, There’s the Stinger

The stinger is located at the tip of the abdomen. The honey bee is the only kind of bee to have a barbed stinger. The barb at the end of the stinger causes the stinger to become embedded in its target. When she tries to fly away, the tip of her abdomen is ripped away, causing her to die.

Inside the tip of the stinger is a venom sac that releases more venom when squeezed. If you are stung by a bee, do not try to pull the stinger out of your skin. Use the edge of a credit card to gently lift the stinger out to avoid releasing more venom into the wound.

Questions & Answers

Question: Is there a particular color that attracts bees to a flower more than others? I am a 7th grader doing a science fair project on bees' eyes.

Answer: Bees seem to have a few favorite colors--they prefer flowers that are yellow, white, purple, or blue. They also prefer flowers with ultra-violet markings. (Bees can see in the ultra-violet spectrum, but humans can not.) Bees are also more attracted to flowers that have a mixture of several colors rather than just one color.

Question: If bees pollinate a farmers field, how much might it increase crop yield?

Answer: The answer is 100%. Some crops can only be pollinated by honeybees. No honeybees, no crop.

About one third of our food would no longer be available if there were no honeybees.

I discuss the importance of honeybees to our food supply in this article:

Question: What are the uses of honey?

Answer: Honey is used by humans primarily as a sweetener.

Honey has a number of medicinal uses. It has antiseptic and antibacterial properties which can help prevent infection and help heal burns and wounds. It might also be useful in reducing diarrhea and acid reflux.

Honey may be a good sugar substitute for some diabetics because it has a lower glycemic index.

Bees use honey as a food supply. During the warm weather months when flowers and their nectar are plentiful, bees produce an excess of honey to get them through the cold weather months.

Question: Where do we get honey from?

Answer: Bees make honey from the nectar they obtain from flowers. You can find a more detailed answer in my other article, "Inside the Bee Hive: How Bees Make Honey."

Question: What does honey contain?

Answer: Honey is a supersaturated sugar solution, a solution that also contains acids, minerals, vitamins, and amino acids in varying quantities. Honey is composed of the sugars, fructose, and glucose.

Honey is made from plant nectar, which is a mix of various sugars, proteins, and other compounds, in a water solution. This nectar is mixed with enzyme secretions from glands in the bee's "honey stomach," a special organ separate from the regular stomach.

Honey contains only about 17% water. Its low water content makes it resistant to bacterial and fungi growth, and thus honey can be kept for a very long time without spoiling.

If you want more detail about the exact composition of honey, the following website provides an excellent chart.

Honey bee and human eyes are NOT alike. Take a look at the book described at the end of this article. There are photographs of honey bee eyes.

Giselle on November 06, 2017:

how do you know if honey bees and humans eyes are alike? If you have time to answer my question I really wanna know.

hi on November 01, 2017:

i love bees

bravewarrior: Thanks for your comment and for your appreciation of bees. Honey bees seem to have a special anatomical part dedicated to each and every need. Their value to the ecosystem is even more amazing. It is estimated that two-thirds of our food crops are dependent on bees.

Shauna L Bowling from Central Florida on March 21, 2017:

These little pollinators have so many body parts! Very informative article, Catherine. Honey bees are self-contained power houses and so vital to a thriving eco-system. Amazing little creatures!

PeggyWoods: Honey bee anatomy is so amazing. It is like ever millimeter of their bodies is put to good use. And such ingenious solutions, like the pollen sacs. Thanks for your comment.

Peggy Woods from Houston, Texas on March 10, 2017:

It is amazing what I am learning by reading your articles about honey bees. Those photos you found to illustrate this post are amazing. Next time I spot a honey bee I will look to see if those translucent sacks are filled with pollen.

Catherine Giordano (author) from Orlando Florida on February 27, 2017:

FlourishAway: Thanks for your comment. Bee stings don't hurt a lot; it is wasp stings that are really painful. Also,usually bees only sting in defense of the hive. If yu do get stung by a bee, pressing the skin to push the stinger out is the best way to remove the stinger.

FlourishAnyway from USA on February 26, 2017:

I loved the detail about their physiology and behavior. I hadn't heard about removing a stinger with a credit card. Fascinating.

Catherine Giordano (author) from Orlando Florida on February 25, 2017:

Thank you, Ms. Dora, for taking the time to read and comment. Everything about these tiny creatures is amazing.
