How do bees predict the weather

There is an agricultural proverb in southern China: "The bees never leave their nests, and it rains in the middle of the night". It can be seen that the time when bees leave the box is closely related to the weather change. Bees have the strongest ability to recognize things, and they can quickly respond to various changes in the weather. For example, in the morning, I saw a large number of bees scrambling to fly out of the hive to collect, which indicates that today is sunny; If the bees come back to the box late at night, it means that the weather will continue to be fine tomorrow; If bees don't leave the box in the morning, leave the box less, or stay in the hive for a long time, it indicates rainy weather. During the day, if bees are found to suddenly jump back into the nest abnormally, many bees will rush into the nest and rarely or never leave the nest. Sometimes, a few bees are found poking around the door of the nest, which indicates that the weather will change suddenly. If bees leave their nests to collect honey in the drizzle after continuous rain, it indicates that the rain will end and the weather will clear up. Therefore, there are proverbs such as "bees will clear up when they leave their nests", "bees will rain if they don't go out to work" and "bees will clear up when they collect honey in the rain".

So, why are bees so sensitive to weather changes? It turns out that the front and rear wings of bees are very thin and easy to fly. Bees are used to flying in sunny weather and high pressure. Before the rain, due to the increase of water content in the atmosphere, high humidity and low air pressure, bees are easy to get wet by tiny water droplets, gain weight, make their wings soft and heavy, slow down the frequency of flapping their wings, and have difficulty flying, so they have to stay in the hive. In addition, judging from the situation of honey collection by bees, it is also closely related to the weather. Sunny, warm and windless weather. It can make the nectaries of flowers secrete a lot of sweet juice, give off a strong floral fragrance, and attract bees to collect it. So we can predict the short-term weather changes by observing the regular activities of bees.
