Beekeeping For Dummies. Howland Blackiston
In this close-up image of a worker bee’s leg, you can clearly see the hairs that serve as brushes to collect pollen.
Abdomen
The abdomen is the part of the bee’s body that contains its digestive organs, heart, reproductive organs, wax and scent glands (workers only), and, of course, the infamous stinger (workers and queen only).
The Amazing Language of Bees
It is said that only man and primates have a form of communication superior to that of the honey bee. Like you and I, honey bees use five senses throughout their daily lives; however, honey bees have additional communication aids at their disposal. Two of the methods by which they communicate are of particular interest. One is chemical, the other choreographic.
Pheromones
Pheromones are chemical scents that animals produce to trigger behavioral responses from the other members of the same species. Honey bee pheromones provide the “glue” that holds the colony together. The three types of adults in a hive, of which more is mentioned later in this chapter, produce different pheromones at different times to stimulate specific behaviors. The study of pheromones is a topic worthy of an entire book, so here are just a few basic facts about the ways pheromones help bees communicate:
Certain queen pheromones (known as queen substance, discussed at greater length later in this chapter) let the entire colony know that the queen is in residence and stimulate many worker-bee activities.
Outside of the hive, the queen pheromones act as a sex attractant to potential suitors (male drone bees from other colonies). They also help regulate the drone (male bee) population in the hive.
Queen pheromones stimulate many worker-bee activities, such as comb-building, brood-rearing, foraging, and food storage.
The worker bees at the hive’s entrance produce pheromones that help guide foraging bees back to their hive. The Nasonov gland (discussed later in this chapter) at the tip of the worker bee’s abdomen is responsible for this alluring scent.
Worker bees produce alarm pheromones that can trigger sudden and decisive aggression from the colony.
The colony’s brood (developing bee larvae and pupae) secretes special pheromones that help worker bees recognize the brood’s gender, stage of development, and feeding needs.
Shall we dance?
Perhaps the most famous and fascinating “language” of the honey bee is communicated through a series of dances done by foraging worker bees who return to the hive with news of nectar, pollen, or water. The worker bees dance on the comb using precise patterns. Depending on the style of dance, a variety of information is shared with the honey bees’ sisters. They’re able to obtain remarkably accurate information about the location and type of food the foraging bees have discovered.
Two common types of dances are the round dance and the waggle dance.
The round dance communicates that the food source is near the hive (within 10–80 yards). Figure 2-4 illustrates dancing movements.
For a food source found at a greater distance from the hive, the worker bee performs the waggle dance. It involves a shivering side-to-side motion of the abdomen while the dancing bee moves in a figure eight pattern. The vigor of the waggle, the number of times it is repeated, the direction of the dance, and the sound the bee makes communicate amazingly precise information about the location of the food source. See Figure 2-4.
The dancing bees pause between performances to offer potential recruits a taste of the goodies they bring back to the hive. Combined with the dancing, the samples provide additional information about where the food can be found and what type of flower it is from.

Getting to Know the Male and the Two Female Castes
During summer months, about 60,000 or more bees reside in a healthy hive. And while you may think that all those insects look exactly alike, the population actually includes two different female castes (the queen and the workers) and the male bees (drones; see Figure 2-5). Each type has its own characteristics, roles, and responsibilities. Upon closer examination, the three look a little different. Being able to distinguish one from the other is important.
Her majesty, the queen
Let there be no mistake about it — the queen bee is the heart and soul of the colony. There is only one queen bee in a colony. She is the reason for nearly everything the rest of the colony does. The queen is the only bee without which the rest of the colony cannot survive. Without her, your hive is sunk. A good-quality queen means a strong and productive hive. For more information on how to evaluate a good queen, see Chapter 8. And for some real fun, try raising your own queens from your best performing hives. See Chapter 14.

FIGURE 2-5: These are the three types of bees in the hive: worker, drone, and queen.
The queen is the largest bee in the colony, with a long and graceful body. She is the only female with fully developed ovaries. The queen’s two primary purposes are to produce chemical scents that help regulate the unity of the colony and to lay eggs — and lots of them. She is, in fact, an egg-laying machine, capable of producing more than 1,500 eggs a day at 30-second intervals. That many eggs are more than her body weight!
The other bees pay close attention to the queen, tending to her every need. Like a regal celebrity, she’s always surrounded by a flock of attendants as she moves about the hive (see Figure 2-6). Yet, she isn’t spoiled. These attendants are vital because the queen is incapable of tending to her own basic needs. She can neither feed nor groom herself. She can’t even leave the hive to relieve herself. And so her doting attendants (the queen’s court, her retinue) take care of her basic needs while she tirelessly goes from cell to cell doing what she does best: lay eggs.

The gentle queen bee has a stinger, but it is rare for a beekeeper to be stung by a queen bee. I have handled many queen bees and have never been stung by any of them. In general, queen bees use their stingers only to kill rival queens that
