During winter, a wooden hive resembles a house heated in only one room

During winter, a wooden hive resembles a house heated in only one room. Near the hive walls, temperatures can drop close to outside levels and even below zero in severe frost. However, inside the dense cluster of bees, the temperature ranges from about +20 to +30 °C. Bees do not warm the entire hive but create a warm living cluster around the queen and food stores, known as the winter cluster. Therefore, the hive itself remains cold while the bees stay warm.
