Anatomy of a Langstroth Hive

Hello! Welcome to your course on beekeeping. In this first module, we'll begin by building your foundational knowledge, starting with the bees themselves and then moving on to their home.

This lesson kicks off our second module, "Essential Beekeeping Equipment." Our goal is to familiarize you with the most common type of beehive used by beginners and professionals alike: the Langstroth hive. By the end of this lesson, you will be able to identify each component of a standard Langstroth hive and explain its purpose within the colony's home. Think of the hive not just as a box, but as a modular, expandable system designed around the natural behavior of bees.

The Langstroth Hive and "Bee Space"

Before we look at the individual parts, it's essential to understand the brilliant principle that makes the whole system work: bee space. In the mid-19th century, Reverend Lorenzo Langstroth observed that honey bees leave a consistent gap of about 3/8 of an inch (or roughly 9.5 mm) between their combs.

• If a space is smaller than this, bees will seal it with a sticky resin called propolis.
• If a space is larger, they will build extra comb to fill it.

The Langstroth hive is engineered so that every internal component—the boxes, the frames, and the covers—maintains this precise "bee space." This simple but revolutionary concept allows beekeepers to easily remove and inspect frames without tearing the hive apart, which is why it's called a "movable-frame hive."

To get a clear understanding of this concept, let's watch a short segment from the University of Florida Honey Bee Lab.

A Visual Tour of the Hive's Components

The best way to learn the parts of a hive is to see them assembled. The following video provides a clear, piece-by-piece walkthrough of a standard Langstroth hive. We will break down each component mentioned in the video afterwards.

Deconstructing the Hive: From Bottom to Top

Now, let's systematically review each major component, working our way up from the base of the hive.

1. Hive Stand (Optional)

While not technically part of the hive, virtually all beekeepers place their hives on a stand. This can be as simple as cinder blocks or a purpose-built wooden rack. A stand raises the hive off the ground, protecting it from moisture, pests (like ants), and making it easier for you to work without bending over too much.

2. Bottom Board

This is the floor of the beehive. It provides the main entrance for the bees and supports the rest of the hive components stacked on top of it. As you saw in the video, there are two main types.

• Solid Bottom Board: The traditional design, made of solid wood. It's durable but can accumulate debris and moisture.
• Screened Bottom Board: This modern design features a wire mesh floor. It offers superior ventilation (crucial in hot climates) and helps with pest management, as debris and Varroa mites can fall through the screen and out of the hive.

For a more detailed comparison, you can read the following section from the "Beginning Beekeeping in Mississippi" guide.

3. Hive Bodies (Boxes or "Supers")

These are the stackable boxes that form the main body of the hive. You'll hear them referred to by several names, but they serve two primary functions: housing the colony's brood (eggs, larvae, and pupae) and storing honey.

• Brood Box / Chamber: This is the colony's nursery and living quarters. It's typically the bottom-most box (or two boxes) where the queen lays her eggs. Beekeepers usually use Deep boxes for the brood chamber.
• Honey Super: These are boxes placed on top of the brood chamber for the bees to store surplus honey. Beekeepers generally use Medium or Shallow boxes for this, as a deep box full of honey can weigh over 70 pounds (32 kg) and is very difficult to lift.

The boxes come in three standard depths:

• Deep: ~9 ⅝ inches tall. Used for the brood chamber.
• Medium: ~6 ⅝ inches tall. The most common size for honey supers.
• Shallow: ~5 ⅝ inches tall. Also used for honey supers, but less common than mediums.

4. Frames and Foundation

Inside each hive body are the frames. These are the removable structures that bees build their wax comb on. This is where the queen lays eggs and where bees store pollen and honey.

• Frames: Wooden or plastic rectangles that hang vertically inside the hive bodies. Their size corresponds to the box they go in (deep, medium, or shallow).
• Foundation: A thin sheet of plastic or beeswax imprinted with a honeycomb pattern, which is fitted inside the frame. It gives the bees a guide, encouraging them to build straight, even combs that are easy to inspect. Using foundation is optional (a practice called "foundationless" beekeeping), but highly recommended for beginners to avoid a mess of cross-comb.

As the video mentioned (foundation color), foundation comes in different colors. Black is often used in brood boxes because it makes it much easier to see the tiny, white bee eggs. Yellow is common for honey supers.

5. Inner Cover

The inner cover is a flat board that sits directly on top of the uppermost hive box. It has two main jobs:

1. It creates a dead air space between the top box and the main lid, which provides insulation from heat and cold.
2. Crucially, it prevents the bees from gluing the top cover directly to the frames with propolis, which would make opening the hive nearly impossible.

Many inner covers have a notch for ventilation and a hole in the center, which can be used for feeding the bees with a jar feeder.

6. Top Cover (Lid)

This is the hive's roof. Its job is to protect the colony from rain, sun, and other elements.

• Telescoping Cover: The most common type for hobbyists. It has sides that overhang the top box, like the lid of a shoebox, offering excellent weather protection. It is always used with an inner cover.
• Migratory Lid: A simpler, flat lid that sits flush with the hive's sides. It's favored by commercial beekeepers because it allows hives to be stacked tightly together on pallets for transport ("migration").

Essential Accessories

While the parts above form a complete hive, most beekeeping kits and setups include two other important pieces of equipment.

• Queen Excluder: A flat grid of wires or plastic that is placed between the brood box and the honey supers. The slots are large enough for worker bees to pass through, but too small for the larger queen and drones. This "excludes" the queen from the honey supers, ensuring they contain only honey and no brood.
• Entrance Reducer: A small block of wood with different-sized notches that fits in the hive entrance on the bottom board. It's used to reduce the entrance size for new or weak colonies, making it easier for them to defend against robbing bees and helping them control the hive's internal temperature.

A Note on Hive Size: 8-Frame vs. 10-Frame

Finally, it's important to know that Langstroth equipment comes in two standard widths: 10-frame (the original standard) and 8-frame.

• 10-Frame: Offers more space for brood and honey. The boxes are wider and heavier when full.
• 8-Frame: The boxes are narrower, lighter, and easier to handle. This is a popular choice for backyard beekeepers.

The bees will thrive in either system. The most important thing is to choose one size and stick with it, as the components (boxes, covers, bottom boards) of the two systems are not interchangeable. This is a key decision when starting, as it dictates all future equipment purchases.

Conclusion

In this lesson, we've deconstructed the Langstroth hive, the standard home for the modern beekeeper. You've learned how the principle of "bee space" governs its design and allows for easy management.

Here are the key takeaways:

• The Langstroth hive is a modular system based on the concept of bee space.
• The core components, from bottom to top, are the bottom board, hive bodies (deeps for brood, mediums for honey), frames with foundation, an inner cover, and a top cover.
• Accessories like a queen excluder help manage where the queen lays, and an entrance reducer helps protect the colony.
• Hives come in 10-frame or 8-frame widths, and it's important to be consistent with your choice.

Now that you're familiar with the bees' house, our next lesson will focus on you. We'll explore the essential personal protective equipment you'll need to wear to safely and confidently approach and work with your bees.
