Have you ever heard that insects have meteorological sentinels that can predict climate changes? Insect forecast weather has been recorded much earlier than weather stations. Some ancient Chinese poems and books can serve as evidence. The character "Xia" in the oracle bone inscriptions of the Yin Dynasty is a pictographic character based on the image of cicada. It can be seen that people have long associated cicadas with summer. When cicadas start chirping, it means that the weather is getting hotter. Our ancestors divided the whole year into 24 solar terms in the lunar calendar, among which "Jingzhe" falls in the second month of the lunar calendar. After long-term observation of insects, the ancients knew that at the time of the "waking of insects", all overwintering insects would wake up and start moving.
Our ancestors linked the activities of insects with seasons and months, and thus summarized the rules of keeping time by insects and recorded them in books. Such as "The Book of Songs." The chapter "July" contains: "In May, katydids move their legs, in June sand grouse flutter their feathers, in July I am in the wild, in August I am in the house, in September I am at home, and in October crickets enter my bed." It means: In May, katydids begin to walk on their legs; in June, the "sand grouse" (weaver chick) rubs its wings together and makes a sound, and can also fly; in August, it arrives under the eaves of residents; in September, it begins Come inside; in October the crickets have to crawl under the hot bed.
Experienced people can predict short-term weather changes and seasons based on the activities or sounds of certain insects. For example, many dragonflies flying low to hunt for food indicate that heavy rain or heavy rain will fall in a few hours. The reason is that the air pressure is low before rainfall, and some small insects fly low. Dragonflies also fly low in order to prey on small insects. Ants are also particularly sensitive to climate changes, and they can predict weather changes in the next few days. It is said that the meteorological department divides the weather into several different types based on the activities of various ants to predict the weather conditions in the next few days. Sunny type: small black ants go out to look for food and the nest door is not sealed, which indicates good weather within 24 hours. Cloudy type: (April-June) Various ants still do not return to their nests at 5 pm. Yellow ants build dams with soil and surround the nest entrance. It is estimated that it will rain for more than four days in a row after four or five days. Cold air type: Big black ants build dams, move, and close their nests; small black ants build dams for four consecutive days, indicating that a cold air will arrive in the future. Heavy rain and rainstorm type: (April to September) large black ants build dams intermittently for more than three days, and climb trees and bamboos; yellow ants build dams with soil, and the weather forecast includes rising temperatures, rising humidity, and falling pressure. Phenomenon, there will be a heavy rain or heavy rain in the next 48 hours. Drought type: Large black ants move from trees to humid places and take their unhatched eggs with them, indicating a longer drought in the future. Of course, using ants to predict the weather still requires reference to local meteorological data to achieve accuracy.
