There are a large number of ephemera in the streets of Dengzhou, and farmers are worried that the bookmakers will be eaten. What's going on here?

More than half of 202 1 has passed, which can be said to be a disaster-ridden year for the people of Henan. Most parts of Henan province have experienced heavy rains and floods. People who have experienced this rainstorm are still scared. After the rainstorm, the city's infrastructure and equipment have been restored little by little. However, not long after the rainstorm, a large number of "moths" flooded into the streets and alleys of Dengzhou City, and relevant departments quickly came to the scene to investigate.

After some investigation, it is found that the "moths" appearing on the streets of Dengzhou are not moths as we know them, but ephemera. This kind of life has a short survival time, but it began to appear very early, more than 200 million years ago. Its most obvious feature is that its wings can't be folded, which is similar to dragonfly, but Mayflies are much smaller than dragonflies. Moreover, the life span of ephemera is very short, only a few hours normally, and only a few days more.

Mayfly is a kind of aquatic insects, which lives in water from eggs to larvae. It takes one to six years to grow wings and fly. There was a similar situation in dengzhou city in the early years, and large-scale ephemera appeared in the streets, so this is a normal natural phenomenon. Moreover, the flood of ephemera confirmed the previous heavy rainfall. Of course, this cannot predict the subsequent rainfall.

There are many creatures similar to ephemera in nature. Especially in summer, ephemera began to flood in large numbers, and some fish that feed on ephemera can get enough food through this biological chain, thus achieving a large increase in fish. It must be said that this is a self-regulation mechanism of nature's biological chain, a series of chain reactions triggered by heavy rain, which is also the self-regulation made by nature in order to maintain stability.

Therefore, Mayflies don't eat bookmakers, so farmers don't have to worry too much. Moreover, after summer, the rainy weather will be relatively less, and the weather in autumn will be drier. The situation of rainstorm here is much smaller, and the probability of ephemera appearing is also very small, so you don't have to worry too much.
