What is the sign that beetles gather in the same place in large numbers? Natural disasters? Or a natural phenomenon?

Every year, when summer comes and the weather gets warmer, seasonal storms will bring abundant rain to the city. At this time of year, all kinds of beetles begin to appear in large numbers, and this situation will continue until February next year. In previous years, these beetles may live in trunks or caves as larvae.

So this is a normal natural phenomenon, and it may just attract your attention. Don't worry.
