Can Bees Recognize Human Faces?

Honey bees show aggressiveness when a stranger approaches the hive. However, most honey bees behave nicely and chill around their beekeeper during hive inspection. This raises the question: can bees recognize human faces?

Honey bees can remember human faces using patterns, smell a process similar to configural processing. However, they can’t recognize face or anything like we do. They consider the arrangement of features like eyes, nose, and mouth as a single pattern.

This is how they recognize the good guy (their beekeeper) and strangers. No other bees can remember faces, patterns, or anything like honey bees.

In this article, we will explore whether bees can truly recognize human faces and how long they can remember them.

 

Can Bees Recognize Human Faces? What Research Says?

Trained honey bees can distinguish photographs of human faces. This does not necessarily mean that a garden bee naturally recognizes you as a particular person.

In a 2005 experiment:

• Five free-flying honey bees were trained with sugar rewards and bitter punishment.
• They learned to choose one target face over similar faces.
• They could identify the target when unfamiliar distractor faces were introduced.
• Turning the photographs upside down significantly reduced performance. This suggests that the arrangement of features mattered, not just one dark or bright patch.

Later experiments found that honey bees and wasps can use “holistic-like” or configural processing. They combine several visual features and their positions when solving a face-discrimination task.

From my personal experience, I have also seen that bees are nice and calm when I inspect them. Whenever any of my relatives or neighbors come to see my bees, they behave a bit weird.

 

Look like my bees are afraid of humans. As strangers trying to interact with them are treated as a threat to them.

My bees were not chill around me when I got my first nuc of bees. I saw during nuc-to-hive transportation that they were trying to sting me.

Also, during the first few inspections, bees were covering my suit. Looks like they were not liking me. However, I had a good quality ventilated full bee suit that saved me from getting stung by bees.

However, with time, I have seen they are not as mad as they were before. Then I felt like they were not considering me as a threat anymore.

Feels like they can recognize me as a safe object. They started behaving more friendly around me.

So, I started leaving the full bee suit. Most of the time now I just inspect beehives with a veil only.

This made me realize some species of honey bees can recognize their beekeeper.

From my perspective, bees are recognizing me because of:

• I fed them sugar syrup.
• I regularly clean their hives, remove dead bees, debris, mites, and hive beetles.
• I provide winterization to the hives before winter.
• Most importantly, my suit contains the odor of honey and debris from frames.

The last point is important. As my bee suit contains the smell of nectar, honey, or similar to beeswax, bees treat me as a friend.

This led me to the conclusion that bees can recognize human faces. However, wasps and other types of bees, including some species of honey bees, might not be able to do so.

 

 

How Long Can They Remember a Face?

Honey bees can learn and remember a particular face image for at least two days. There is little direct evidence that they naturally recognize an individual beekeeper’s real face across different angles, clothes, lighting, and locations.

The experiment I mentioned earlier shares the strongest direct result is at least two days after training.

Only two bees were tested after 48 hours:

• Bee 1 declined from 93.9% to 79.2% correct.
• Bee 2 declined from 87.4% to 75.9% correct.

Both remained above random choice. However, because only two bees received this memory test, scientifically we cannot confidently claim that bees remember human faces for weeks or months. This is what scientific evidence proves.

But from my experience, bees are able to remember me for up to 2 weeks. Because when I inspect beehives with the right timing within 14 days, they don’t show any aggressiveness.

Whenever I take a break of 15 days or more from hive inspections, my bees start behaving as if I am a stranger to them. The longer the gap, the more aggressiveness is observed from bees.

I usually inspect the hive 1-2 times per week or once every two weeks based on the season. During winter, I open the hive only once a month.

Note: Bees do not want to come up at any condition. Thus you should avoid hive inspection under some conditions. Because timing is really crucial for beehive inspection. Wrong timing will not welcoming for bees.

From my experience, I observed that bees can remember me for up to 10-14 days. I have Apis cerena. Other bee species may behave differently.

 

 

How to Be Friendly with Bees?

Some people have a fear of bees. But most bees are totally harmless. They won’t attack you until you behave like a threat to them.

Here are some tips to be friendly with bees. If you are a beekeeper, these practices will help your bees remember your face for days.

• Don’t run or move quickly when passing by a beehive.
• During hive inspection, wear light color dress. Most prefer a white bee suit.
• Don’t use any hard smell, avoid perfume or body spray.
• Don’t keep anything close to a beehive that bees don’t like.
• Try to plant more and more bee friendly plants in your garden.
• Don’t overinspect. Follow proper beehive inspection rules.
• Don’t run an oscillating machine or high-volume music close to a beehive.
• Provide sugar syrup and a water source during the scarce season for bees.

Bees might show more aggressiveness during fall. It doesn’t mean they are not recognizing you. It might be because of:

• They lost the queen.
• The hive became overcrowded.

So, inspect the hive properly and make sure the hive is queen-right. If the hive becomes overcrowded, make sure to split the beehive so that bees have enough space to live.

In case the hive becomes queenless, first give them a few days to raise a new queen from existing larvae. If workers fail after a few days, make sure to requeen the queenless hive. Without the queen, the colony will die.
