Honeybee Antennae

Antennas are fascinating devices that receive signals from other places so that those signals can be converted into useful information. In our daily digital lives, we use antennas that pick up Wi-Fi and Bluetooth signals in our electronic devices and computers. In addition, we use TV and radio antennas to receive signals that are converted into sound and pictures.

When considering antennae in living creatures, aliens and insects are the first things that come to mind. Insects are very alien looking and may have been the model for how we imagine aliens!

Antennae exist for insects to serve a central purpose—to sense the world. Just like how humans have five senses, antennae exist to help insects touch, smell, taste, and, in some cases, hear what’s going on in the world around them. Antennae can pick up outside stimuli like air motion, heat, and sound. They’re often referred to as “feelers.”

For honeybees, antennae are arguably one of the most important sensory organs on their bodies. Honeybees have antennae to help them navigate the world—to find and taste food, find mates, sense direction, and sense danger. For us, it would be like having our noses and ears on our fingertips. Through their antennae, honeybees are able to communicate with other bees in the colony and assess their environment, which is essential to their survival and well-being.

If we were to compare honeybee antennae to human anatomy, the antennae would be a combination of our hands, nose, tongue, and ears all in one! Although bees can’t hear as we do, their antennae are useful for picking up sound vibrations around them. Studies have proven that bees are able to detect sound despite not having the same ears as humans. Some scientists even go as far as to say that antennae provide a magical sensory system since antennae can detect things that humans often aren’t very distinctly aware of, such as electric fields, humidity, chemicals, gravity, temperature, and wind speed.

Just like the worker and drone bees, queen bees also have antennae to help them sense what’s going on in the world around them. Like other bees, the queen bee uses her antennae to communicate with other bees and receive input from the environment around her. Queens, in particular, need to know the status of each honeycomb cell since honeycomb cells are where she deposits her eggs. Beekeepers often can spot queen bees investigating honeycomb with her antennae, likely determining the availability of an individual cell to receive a fresh egg.

Why Do Beekeepers Need to Purchase Queen Bees?

While each of the honeybees in a hive plays their own role, the queen bee is unique in that she influences the behavior and performance of an individual colony in a way that no other single bee can. She is the genetic backbone of the colony—and all the bees, as her offspring, carry her genetic signature.

As a result, beekeepers know that they can control the performance of a colony to a significant extent simply by managing the quality of the queen bee in the hive. There are two pieces to assessing a queen’s quality: the performance of her offspring, and of course, her own performance. Both are vital.*

For assessing a queen’s offspring’s performance, a beekeeper commonly considers the following:

  • Disease Resistance: Is the colony robust and able to withstand diseases such as American foulbrood?
  • Temperament: Are the bees gentle and easy to work with?
  • Honey Production: In conditions of good nectar flow, are the bees making a considerable amount of honey?
  • Honey Consumption: Does the colony save its stores or consume large amounts of honey, requiring extra supplemental feeding?
  • Population Control: Does the colony have the desired population at the right time of year?
  • Mite Resistance: Does the queen carry the VSH trait to control the spread of parasitic mites?
  • Swarming Tendency: Does the colony seem to want to swarm more than normal?
  • Overwintering Success: Does the colony appear very weak in the spring?

In assessing a queen’s own performance, the beekeeper also considers the queen herself:

  • Laying Performance: Is the queen laying enough eggs and in a tight brood pattern?
  • Quantity of Drones: Is the queen laying more drones than worker eggs?
  • Health: Is the queen injured?
  • Age: Is she young and vigorous, or aging and on the way out?
  • Presence: Is she even in the hive, or did she perish somewhere along the way?

So, why do beekeepers need to purchase queen bees? The first reason is to manage the genetics of the offspring. The second is to manage the performance of the queen herself.

The third, and perhaps most common reason for purchasing a queen bee, is to enable the beekeeper to easily divide or split an existing colony. All new colonies need queens. The easiest, most reliable, and most surefire way for a beekeeper to obtain a quality queen of known genetics is to purchase that queen from a reputable queen breeder.

*With an instrumentally inseminated breeder queen, the queen’s own performance is more important than the offspring’s because the genetics in the offspring are already largely predetermined due to the selection of the parents.

Queen Introduction – Balling the Queen Bee

Beekeepers have struggled with how best to introduce a new queen into a beehive for ages – whether they’re wanting to requeen an existing colony of honeybees or place a new queen into a newly created colony. When a colony of honeybees is presented with a new queen, the bees’ first instinct is to act aggressively towards her. Since her pheromones do not match the hive, the bees see the new queen as an intruder and will instinctively come after her.

If a newly introduced queen is not protected during the introduction period, it is almost guaranteed that the colony will kill her. The worker bees will approach her aggressively –quickly grabbing onto her and not letting go. First, one bee starts this behavior, then another, and another – before long, honeybees will surround the queen, grabbing on and not letting go.  This is known as balling.

When a newly introduced queen is being balled, she is in trouble. The worker bees will grab at her body parts, and very possibly, sting her to death. This is why queen honeybees are almost always introduced to a new colony while inside some sort of cage. The cage protects the queen from an almost certain onslaught and gives her a safe place to hide.

Even with a cage, the bees will still attempt to ball the queen. However, with a cage in the way, the most that the bees can do is grab onto the cage and attack it, sparing the queen inside. Over time, the worker bees gradually cease balling the cage – one by one giving up and allowing the queen a little reprieve, while she is still safely protected inside of the cage.

While this is all happening, the colony’s worker bees are eating through the candy release tube in the cage. Well before the bees have worked their way through the candy, the balling bees have given up and have gone back to their usual work within the hive.

Even once the queen has been released from her cage, she still is somewhat at risk for renewed balling, until she actually starts laying eggs. This is why most experienced beekeepers, including us at Wildflower Meadows, always advise leaving a colony alone for a full week after the introduction of a new queen. Only when she is laying eggs can a newly introduced queen be truly considered as accepted by the colony, and relatively free from the risk of being balled.

How Often Should a Beekeeper Requeen?

While queen honeybees can theoretically live for up to five years, they rarely do. As queen bees age, their productivity declines. A three-year-old queen is generally less prolific than a two-year-old queen. Even a two-year-old queen can sometimes be less prolific than a queen who’s only one year old – which is why many beekeepers prefer to requeen annually.

Many beekeeping authorities recommend requeening colonies after a certain point in the queen’s life, usually after one year. The theory is that by replacing an older queen, a colony will be more robust and successful, due to a younger queen’s greater productivity. A younger queen creates a higher volume of bees than an older queen, which results in more bees for pollination and greater honey production, and also more bees for expanding colony counts.

Young queen bees also tend to have a stronger pheromone signature. When a young queen’s powerful pheromones are present, a beehive knows it has a quality, vigorous queen in hand. As a result, the colony sees little need to replace her. Likely for the same reason, colonies with younger queens are less likely to swarm than colonies with older queens. A young queen seems to set a beehive at ease and enable the bees in the hive to relax and focus on the business at hand.

Even though requeening annually has its benefits, there are equally strong arguments against this practice. The policy of requeening every colony, every year fails to consider the very real possibility that an existing queen may be a superstar with several years of performance left. What’s the benefit of replacing a proven winner with a new queen, that may or may not match the existing queen’s excellent performance?

Regular requeening can also become costly – in terms of both the cost of the new queen itself, as well as the time it takes to find and introduce a new queen each year. Plus, there is always the risk that the introduction of a new queen may not even be successful, leaving the colony without any queen at all!

At Wildflower Meadows, we believe it makes the most sense to consider each colony on a case-by-case basis. When deciding whether to requeen, it’s important to assess whether the existing queen is still laying a quality brood pattern. A queen on the decline in her later years will typically begin to show a “spotty” brood pattern, rather than the tight, circular brood pattern of a young, vigorous queen. Any queen with a consistently spotty brood pattern is always a candidate for requeening. Most queens that are more than two or three years old are also excellent candidates for requeening. Queens of that age are not far away from an almost certain drop-off in productivity, making requeening the best decision for maintaining a strong, productive hive.

Two Queens in a Hive

Most beekeepers know that a hive only contains a single queen. However, this isn’t necessarily always true. There are times when a colony may have two queens; and while it’s usually short-lived, the scenario probably happens more often than most beekeepers realize.

As we know, a queen bee releases pheromones to make the worker bees aware of her presence, and that she’s actively laying fertile eggs. As the queen ages, these pheromones naturally weaken, which lets the worker bees know it’s time to start the process of raising a new queen. Worker bees may plan to supersede an older queen when they notice a decline in her productivity as well.

An instance where a hive has multiple queens may occur when a new queen hatches while the old queen is still living. After a daughter hatches, one of the following scenarios will likely transpire – either the worker bees will kill the old queen, the two queens will fight to the death, or the hive will swarm. Unfortunately, there is no way for beekeepers to know how their hive will handle this situation, as there are a lot of factors in play.

More often than not, an old queen will not live long after a new queen has hatched. If the newly hatched queen doesn’t kill her, the worker bees themselves may do so. Worker bees will kill their old queen when they notice she’s consistently laying infertile eggs, and they’re comfortable that the new queen is mated and producing well.  A colony will typically prefer the newer and younger queen who, of the two, more often than not will have the stronger performance and pheromone signature.

However, if the older queen is still performing well, the worker bees may alternatively decide to separate the queens into different areas of the hive. This prevents the queens from killing one another and allows the hive to be temporarily more productive – at least until nature inevitably takes its course.

Many times, beekeepers fail to realize they are dealing with multiple queens.  Typically, when a beekeeper is requeening a colony, he or she will stop looking for a queen as soon as the old queen is spotted, not realizing there may actually be yet another queen in the colony.  This can be a challenge when beekeepers are actively trying to introduce a new high-quality queen they have purchased. If a beekeeper attempts to introduce a new queen, thinking the hive is queenless when it’s not, the colony will, unfortunately, almost certainly not accept the new queen – which will likely end in a failed queen installation.

How Does a Bee Become a Queen Bee?

When we raise queens here at Wildflower Meadows, we start the process by grafting worker larvae from our breeder queens.  This procedure transfers the genetic material from our champion breeder queens to our cell building colonies, that will raise the queens which we sell year-round.

Did you happen to catch the words “worker larvae?” Isn’t it strange that the same larvae that were once destined to become worker bees, can be redirected into becoming queen bees? An individual fertilized larva contains the genetic material to become either a worker bee or a queen bee. What happens is that the bees themselves do a sort of genetic modification to the larva, depending on their desired outcome.

When we place these worker larvae into one of our powerful cell-building colonies, the colonies are already strong and queenless. They have a high motivation to develop queens. So, how does a beehive change the course of development of worker larvae to become queen larvae when all the larvae originates from the same source?

Scientists and beekeepers have been asking this question for ages. An obvious clue to the answer lies in the different diets of these two types of honeybees. Queen bee larvae are fed royal jelly, whereas worker bee larvae are fed worker jelly.  There seems to be no other variable to explain the change in development. Yet, how does diet trigger certain genes to be activated?

For many years, scientists and beekeepers have assumed that because a queen larva is fed royal jelly, the trigger to queen development must lie within the royal jelly itself. In fact, most scientists always assumed that there was some magical ingredient within royal jelly that initiates the genetic modification, triggering fertility, and queueing the development of ovaries, etc.

We now know that this is not entirely true.

While it is certainly diet that determines a larva’s development, scientists have discovered there’s no magical ingredient in royal jelly which triggers queen development. It’s actually the diet of the workers that is suppressing queen development!

Worker bee jelly, unlike royal jelly, contains pollen and honey. Pollen and honey, being directly derived from plants, contain plant materials known as phenolic acids, or flavonoids. These phenolic acids deactivate the genes responsible for developing ovaries and reproductive systems. In other words, these phenolic acids suppress queen development in workers.

Royal jelly, on the other hand, is entirely a secretion of bees.  It is a pure bee product that does not contain any plant product – it is completely, 100%, devoid of phenolic acids. The absence of phenolic acids allows a queen bee to fully activate her reproductive genes and completely develop her robust reproductive system.

How efficient is it that honeybees have developed such an amazing way of raising two very different types of bees from the same source? Think of how much more complicated a beehive would be if the bees required different genetic larvae for both workers and queens. By performing this genetic modification on the same source, honeybees have developed an elegant solution for raising queen bees on demand!

Fertilized vs. Unfertilized Eggs – A Queen Bee’s Gender Reveal Party

Some of us enjoy celebrating “gender reveal parties” – because the truth is, no one really knows whether a human infant will be male or female until birth (or close to birth in the case of an ultrasound.) Before this technology, however, it was anyone’s guess whether a child would be born as a boy or a girl. During the early stages of pregnancy, the odds of a child developing as one or the other are random, and more or less equal to a coin toss.

Imagine, however, if we humans could determine the sex of our offspring – not when the child was born, nor earlier with an ultrasound scan, but rather at the time of conception! How different and crazy would our world be if there were such a scenario?

Believe it or not, this is the way honeybees determine the sex of their offspring. It’s actually the queen who dictates the sex of her offspring – literally at the time of egg-laying. When a queen lays an egg, she has her own method of laying either a fertilized or unfertilized egg.  As the egg passes through her oviduct, the queen can choose to fertilize the egg by releasing a tiny amount of her stored sperm from her spermatheca. This will fertilize the egg. Conversely, the queen can also choose to not fertilize the egg.

A fertilized egg will become a female honeybee – either a worker bee or a queen bee. An unfertilized egg will develop into a male honeybee – destined to be a drone. In a healthy colony with a healthy queen, most eggs are fertilized. This makes sense since the vast majority of honeybee colonies consist of worker bees, which are always female.

It is astonishing that a single insect, the queen, has this powerful ability to dictate the sex of her offspring right at the time of conception. It is equally astonishing that somehow, she can determine the right quantity of drones and the right seasonality for laying drones at any given time. All of this is within her power, and somehow, she knows exactly what to do.

How much of this decision-making lies within the queen herself versus within the colony is not entirely clear. Is the colony acting in the same way that a baseball catcher acts with a pitcher, calling the type of pitch to throw? Or is the pitcher herself calling the shots in this case? Scientists believe that both are happening, although the queen clearly dictates the final decision.

The colony itself has some influence in determining the number of drones by the way they choose to allocate the honeycomb when building. If the worker bees construct a large amount of drone-sized comb and point the queen towards it then the queen will lay more unfertilized eggs (drones). If the colony does not build any drone-sized honeycomb, then the queen will only lay worker brood. With no appropriately sized comb, what choice does the queen have after all? It is also possible for worker bees to use pheromone signals to help influence the overall frequency of drone laying.

Raising Your Own Queen Bees

Here at Wildflower Meadows, we take pride in being a reliable source for quality queen bees for our many loyal customers – both repeat and new. Raising queen bees is more than just our job; and we are pleased when our customers can enjoy the fruits of our hard work and expertise.

Believe it or not, we are also equally happy when a beekeeper takes it upon him or herself to learn the science and art of queen rearing.   At that point we share the joy of a beekeeper, who in learning how to raise queen bees, joins a select group of beekeepers who not only manage honeybees but are self-sufficient in meeting their own queen needs.  Queen rearing is advanced beekeeping.  There is a bit of a learning curve, but the benefits of knowing how to raise one’s own queens are huge.

The first and perhaps most valuable benefit is self-sufficiency.  Imagine the notion that you can have your own source of queen bees more or less whenever needed, on-demand.  This means no waiting during the peak season, no scheduling with your queen provider, and no placing orders months in advance. You’re the boss, and you raise your queens when you need them and when the timing is right for you and your hive.

Plus, you’ll likely save money – perhaps a lot of money.  The more queens that you raise, the lower your cost per queen becomes.  Sure, you need to purchase breeder queens and some basic supplies upfront, but once your system is in place, you can literally raise thousands of high-quality queen bees – or as many as you need.  After your initial outlay, the cost of producing every incremental queen is minimal, besides some basic ongoing supplies. The more queens you produce, the more money you save.

If you start with a Wildflower Meadows instrumentally inseminated breeder queen, your stock will carry the optimum Wildflower Meadows genetics that we are known for.  The difference is now you’re in control of both the timing and scale of your queen production.

Raising queens gives you the direct, satisfying experience of witnessing the joy and magic of a queen’s transformation first-hand: from larva to pupa, to virgin queen, and finally to a quality mated queen that you can truly call your own.

Breeder Queens vs. Mated Queens: What’s the Difference?

Beekeepers looking to purchase a queen bee sometimes ask us – what makes a breeder queen unique, and why does a breeder queen often cost nearly ten times the amount of a regular mated queen?

A breeder queen is the cornerstone of a successful bee breeding program. While a breeder queen could certainly take part in regular honey production and beekeeping activities, such as pollination – and most likely would be a superstar in such endeavors – this is not the breeder queen’s purpose. A breeder queen is the carrier of the finest, specially selected genetics, almost always instrumentally inseminated – she is a prized specimen, too precious for ordinary beekeeping.

The vast majority of queen honeybees sold by most queen producers (including Wildflower Meadows) are commonly known as mated queen bees, sometimes also called laying queen bees.  These queen honeybees have been naturally open mated.  While these mated queens are generally of high quality themselves, they are not instrumentally inseminated, and therefore always contain a percentage of unknown genetics.

Unknown genetics may present risks within a breeding program.  An open mated queen will mate with approximately 15 drone honeybees, all of which may potentially be from unknown origins.  If a regular open mated queen is used for breeding, she is guaranteed to pass along hybrid and unknown genetics to her daughter queens, creating variability in her offspring.  With up to 15 unknown drones (fathers) in her genetic profile, there is no guarantee of uniformity and optimum genetics in her offspring.  The open mated queen’s daughters will almost certainly be hybrids and may be inconsistent in performance and quality, which is not ideal for breeding.

A breeder queen has been specifically bred, selected, and inseminated for genetic excellence – which is why breeder queens are more valuable for breeding.  The advantage of a breeder queen versus an open-mated queen is that a breeder features pre-selected F1 maternal AND F1 paternal lines that are 100% known and carefully identified. There are no unknowns with instrumental insemination – everything has been optimized for quality and uniformity.

Optimal genetics are vital to the growth of strong colonies. A beekeeper who wants to breed should start with carefully selected, pure genetic lines that are of known origin on both the maternal and paternal sides. This is the advantage of instrumental insemination and is what makes the breeder queen so unique and prized among honeybee breeders.

Queen Cups vs. Queen Cells

Honeybees are natural comb builders and always seem to be working on some sort of construction or renovation within their hive.  When bees are working on frames of honeycomb, they construct two sizes of honeycomb cells: worker-sized (or regular) honeycomb, or drone-sized (larger) honeycomb. These two sizes accommodate the size difference between worker bees and drone bees.  Drone honeybees are larger than workers, and can’t really fit into a regular honeycomb cell.

Most of the honeycomb that bees build is regular size, which the bees utilize for raising worker bees.  This makes sense since the vast majority of bees in any beehive consist of regular worker honeybees.  A smaller percentage of honeycomb, however, is larger sized, which the hive uses to raise drone honeybees.  In a healthy beehive, there are always more worker bees than drone bees so it is understandable that there would be more worker-sized comb cells than drone-sized comb cells.

What about the queen though?

Amid all this comb construction, the bees will occasionally decide to build a placeholder for a future queen cell – this is a queen cup.  A queen cup looks like an upside-down teacup.  It is more or less the foundation of a queen cell, without actually being a queen cell.  It is as if the bees have done the math – about 90% of a hive consists of worker bees, about 10% consists of drones, and there is a tiny, minuscule less-than-1% percent consisting of the one and only queen.  As a percentage basis, queens are a negligible percent of the hive’s population.  Therefore, the amount of comb dedicated to raising queens needs to be equally negligible.  The queen cup is a tiny acknowledgment that once in a while a beehive needs to raise a new queen.

Most of the time queen cups are unused and can linger around for years at a time.  If a beekeeper discovers a queen cup in a colony it is no cause for concern, unlike finding a queen cell.  The queen cup is merely a placeholder, for potential use at a later date if the hive decides for whatever reason to raise a new queen.  Having the queen cups in place makes building future queen cells just a little bit easier for the bees.

However, when a beekeeper discovers an actual live queen cell inside a colony, it is almost always a cause for concern.  Honeybees do not build queen cells unless they have an immediate and specific reason – unlike queen cups which bees will build just for their own sake. If honeybees are constructing queen cells it is likely due to one of several reasons.  From the beekeeper’s perspective, none of these reasons are good.

A few of the most common reasons bees that bees construct queen cells include:

  1. The hive is preparing to swarm
  2. The colony is without a queen and is in the process of raising an emergency replacement.
  3. The colony has decided that the current queen is of poor quality and needs to be replaced.
