What is the reason for the huge flying ant colony over Britain?

According to CNN 18, British weather radar recently detected rain in southeast England, but it didn't rain there. Satellite images also show that there are no clouds in this area. Experts analyze radar images and think that the particles in the images are bigger than raindrops and more like bugs. Sure enough, the local people found a large number of flying ants flying in the air.

The flying ant colony is extremely huge, stretching for about 80 kilometers in the air and hovering above the weather radar for 2 hours, which makes the weather radar "stunned". Biologists say that the gathering of flying ants is annoying, but beneficial to the ecosystem.

Distribution range of flying ants

Flying ants, that is, termites, are distributed in six continents except Antarctica, mainly between the equator and 45 degrees north and south latitude. There are more than 3000 known species of termites in the world. According to the computer simulation analysis of American scientists, the number of termites in the world is about 0.5 tons per capita. According to the individual weight of termites 1 gram, the number of termites owned by human beings is about 500,000 per capita. This is indeed a sensational figure, and it is indeed true.

China is located in the east of Asia, across the Oriental Region and Palaearctic Region, with extremely rich termite species. There are 4 families, 44 genera and 479 species of termites, most of which are distributed in the south, and a few are found in Liaoning, North China and Northeast China. Among them, there are more than 70 species of termites endangering buildings, and the main species is 19.

The distribution of termites in China is mainly in the vast area south of Huaihe River, which is gradually scarce to the north and gradually increasing to the south. Except Xinjiang, Qinghai, Ningxia, Inner Mongolia, Heilongjiang, Jilin and other provinces (regions), other provinces (regions) have their distribution records.
