As autumn gives way to winter, honeybee colonies across the Brecon Beacons and beyond begin an extraordinary transformation. The gentle hum of the hive may seem quieter as temperatures drop, but inside, the bees are working together in a meticulously orchestrated survival strategy as the bees prepare for winter. Unlike many other insects that hibernate or die off as the cold approaches, honeybees remain active throughout the winter. They don’t leave their hive, but instead, they adapt their behavior to keep their colony alive and thriving, even in the harshest conditions.
The Winter Cluster: A Marvel of Cooperation
One of the most remarkable aspects of honeybee winter survival is the formation of the winter cluster. When temperatures fall below 10°C, bees gather into a tight ball around their queen. This cluster is essential for generating heat. At the heart of the cluster, where the queen resides, temperatures remain a comfortable 30-35°C, thanks to the efforts of the worker bees. The workers vibrate their wing muscles to produce heat, much like how we shiver to keep warm. However, this process requires energy, which is why bees rely on the honey they’ve stored during the warmer months. The bees rotate positions within the cluster, with those on the outer edges taking turns moving inward to warm up, while the bees in the center move outward to give them a break. This continuous movement ensures that no bee is left out in the cold for too long.
At The Good Life Wales, our own colonies at Brecon Beecombs undergo this incredible transformation each year. As the temperatures drop in the Brecon Beacons, we can see firsthand how the bees begin to gather inside their hives, preparing for the long winter ahead. For novice beekeepers, witnessing this natural behavior is a powerful reminder of the resilience and intelligence of these tiny creatures.
Conserving Energy and Resources
In addition to forming a winter cluster, honeybees also adapt their food consumption to survive the colder months. During the summer, bees work tirelessly to gather nectar and pollen, which they convert into honey. This honey is stored in the hive and serves as their primary food source during winter.
As temperatures fall, the bees reduce their activity, leaving the hive only on rare warm days to make cleansing flights. This reduction in activity means they consume less energy, allowing them to stretch their honey reserves over several months. However, if a colony has not stored enough honey by the time winter arrives, the bees risk starvation.
Beekeepers play a crucial role in ensuring their colonies have enough food to survive. For those who join our Introduction to Beekeeping courses at Brecon Beecombs, understanding the seasonal behavior of bees is a vital part of learning how to care for a hive. Knowing when and how to feed your bees during the fall and winter months can make the difference between a thriving colony and one that struggles to survive.
Winter Hive Preparations for Beekeepers
While bees are incredibly resilient, they still need a helping hand from beekeepers to get through the winter. Preparing your hive for winter is one of the most important tasks you’ll undertake as a beekeeper. Here are a few essential steps that we teach in our Introduction to Beekeeping courses:
- Check Food Stores: In late autumn, it’s essential to check your hives to ensure they have enough honey to last through the winter. A typical colony needs around 15-20 kilograms of honey to make it through. If your bees are low on stores, you may need to supplement their food with a sugar solution or fondant.
- Hive Insulation: While bees are excellent at keeping themselves warm, you can help by insulating the hive. In areas like the Brecon Beacons, where temperatures can drop significantly, adding insulation to the top of the hive or wrapping the hive in breathable materials can help maintain warmth without causing condensation.
- Ventilation: It might seem counterintuitive, but proper ventilation is crucial for a healthy hive in winter. Without good airflow, condensation can build up inside the hive, which can freeze and cause cold, damp conditions that are deadly to bees. Make sure your hive has a small upper entrance to allow for ventilation without losing too much heat.
- Pest Control: Varroa mites are a significant threat to honeybees, and winter is no exception. Before the cold weather sets in, it’s important to treat your hives for mites to ensure that the colony isn’t weakened by infestations going into winter.
At Brecon Beecombs, we guide new beekeepers through each of these steps, providing hands-on experience to ensure they feel confident in caring for their hives throughout the year. Our courses emphasize the importance of understanding the natural behaviors of bees and how to support them, particularly during the challenging winter months.
The Role of the Queen Bee in Winter
Throughout winter, the queen bee remains at the center of the cluster, where she is kept warm and safe. During the colder months, her egg-laying activity slows significantly or stops altogether. However, her presence is still vital for the colony’s cohesion. The workers rely on her pheromones to maintain the colony’s structure and morale.
As the winter progresses and the days start to lengthen, the queen will begin laying eggs again. These early eggs will become the first batch of worker bees that help the colony recover from winter and prepare for spring. By late winter, the queen’s egg production will ramp up, signaling that the hive is getting ready for the new season of growth and expansion.
Fascinating Facts About Winter Bees
Winter bees are quite different from their summer counterparts. While the average lifespan of a worker bee during the summer is just six weeks, winter bees can live for several months. These bees have a higher fat content in their bodies, which allows them to survive the long, cold winter and care for the colony until the new generation of workers emerges in spring.
One of the most fascinating aspects of bee behavior is their ability to sense temperature changes and adapt accordingly. When temperatures drop, bees instinctively gather into their winter cluster. Conversely, if there is an unusually warm day during winter, bees may break the cluster and leave the hive for short cleansing flights. These flights allow them to expel waste outside the hive, keeping the interior clean and healthy.
Beekeeping in the Brecon Beacons
The unique climate of the Brecon Beacons presents both challenges and opportunities for beekeepers. The cooler, wetter conditions mean that beekeepers need to be particularly vigilant in preparing their hives for winter. However, the abundance of wildflowers and plants in the area also provides bees with excellent foraging opportunities during the spring and summer, allowing them to build up strong honey stores for winter.
At The Good Life Wales, we’ve tailored our Brecon Beecombs courses to reflect the specific needs of beekeepers in this region. Our hands-on courses are designed to give both new and experienced beekeepers the knowledge and skills they need to manage their hives successfully throughout the year, with a particular focus on winter preparations and ensuring colony survival.
