You wouldn't think that you'd ever hear a beekeeper complain about his bees making too much honey. However, this happens. You see, beekeepers want to keep as many bees as they can so that they can get more honey from each hive. However, sometimes bees can bring in so much nectar that unless the beekeepers is able to keep up on providing more space for the bees to put that nectar/honey, the bees can make it so the queen has no more room to lay eggs. As soon as this happens, the hive is said to be "honey-bound". The bees will swarm from this hive because they've essentially outgrown it.
Perhaps because I was gone so long and unable to inspect and put on my second medium super, when I last inspected my bees a large portion of the second deep (normally for rearing brood) was full of nectar and capped honey. In my opinion my bees are pretty close to being honey bound. I did find swarm cells at the bottom of the frames and some did indeed have an egg in them. I destroyed quite a few of these cells. In the future, I may leave them. I think there is some risk in that if the bees do swarm, I want a new queen to be in the works and not have destroyed my bees' chance to save themselves from a queenless doom. When I returned from vacation, I immediately put on my second super. Just this last inspection I switched the positions of the supers so that the one that the bees have filled nearly entirely with capped honey is now on the very top and the super that still needs to have wax drawn out is now just on top of the second deep.
Now, it is the middle aged 10-20 days old, bees that are the comb building, wax drawing bees. These are also the bees that are mostly involved in the nectar processing within the hive. They are sometimes called the food-storer bees. Their job is to unload the bees that have been out foraging for nectar. A forager returns and seeks out a food storer bee to unload their nectar/pollen. If the bee is able to find a food storer bee within an average of 20 seconds, then that means that there are likely less foraging bees than food storing bees. So, if the foraging bee determines that her nectar source is energetically efficient (i.e., the sugar concentration of the nectar and the amount of available forage and distance from the hive will net more energy gained than lost) she will likely perform a waggle dance. Waggle dances are only performed by bees when they deem their nectar source to be valuable enough to merit recruitment of other bees. Part of this feedback on whether the source is indeed valuable is given via the length of time required to find a food storer bee, the other part via the bee's innate judgement of the nectar source's value. If a specific nectar source is being advertised extensively via waggle dances (which will recruit unemployed foraging bees to find the source), then more bees will quickly find that nectar source and begin to forage and bring back nectar from it. This will have a cross-inhibition effect on nectar sources that are not as valuable. Because bees foraging at a less valuable nectar source will have to spend more time looking for a food-storer bee and hence will perform less waggle dances and there will be less recruitment to that nectar source and bees will be more likely to abandon forage at that source.
Interestingly, I learned while reading Thomas D. Seeley's book The Wisdom of the Hive, that when there are not enough foragers (say at the beginning of the day -- early morning), when a returning forager enters the hive, it may go up to an inactive bee and grab hold and shake it. This seemingly "awakens" the bee and makes it much more likely to go out and forage. This seems to be a signal to recruit more bees to forage.
Another signal that bees give is called the tremble dance. This dance is different than the waggle dance though it does involve shaking. However, instead of just the abdomen shaking, the entire body and legs shake back and forth. This dance is performed when there is a sudden influx of nectar and there aren't enough food storer bees to unload foragers from profitable nectar sources. This dance is performed further into the hive where nurse bees are caring for brood. It causes inactive or brood caring bees to become food storer bees.
I tell you what bees are truly amazing. I have to agree with Lorenzo Langstroth, the inventor of the movable frame hive and Father of Modern American Beekeeping, that honeybees are a witness of a divine creator!
So, it is my hope that my second, empty, undrawn medium super will be drawn out by hard-working middle aged bees so that the nectar in the brood areas can be moved up into that super so that the queen has more room to lay her eggs. The fact that wax is energetically more expensive to produce than honey may also help relieve the overflow of nectar in my bees' brood area. In fact, it takes 6 g of sugar/honey for every 1 gram of wax produced. The bees will naturally move this nectar and honey up as that is how they store their food. Honey on top, pollen just below that, then brood. Honey and pollen on the outsides of the hive. Brood in the middle. Laying eggs is important nearly year round with bees in order to replace the die off rate of foraging bees. During the summer bees (except for the queen) may live only 4 to 6 weeks, though they'll live longer in the winter when they are inactive.
Here are some interesting notes from The Wisdom of the Hive: Social Physiology of the Honeybee:
A patch of flowers 100 square meters about half the size of a tennis court, represents less than 1/125,000 of the area enclosed by a circle with a 2 km radius (and bees can fly up to 6 km radius from the hive) yet remarkably a honey bee colony has a probability of 0.5 or higher of discovering any such flower patch located within 2 km of its hive.
An average foraging trip for a bee results in either 15 mg of pollen or resin (propolis) or 30 mg of nectar or water. Many foraging trips are performed each day.
Yearly colony wide approximately 20 kg. of pollen, 120 kg. of nectar, 100 g of propolis, and 25 liters of water are collected. During the summer bees will consume 70 kg of nectar. This leaves 50 kg of food storage that the bees amass each summer. Much of this comes during what is termed "nectar flows" periods of intense flowering by certain sources that last perhaps only a week or so perhaps shorter due to inclement weather, etc.
Next time you see a honeybee, stop and take a look at it and marvel at the work it performs! I recently read a quote that I liked, "Only God can make blood and honey."
