Why do dormant insects come out of holes in the season of fright?

Because the weather is getting warmer.

Sting is the third solar term in spring, which falls around March 5 of the Gregorian calendar every year. During the period of fright, everything recovers, the temperature rises, the spring is full, and the rainfall increases obviously, showing a scene of abundant opportunities.

The word "sting" means hiding, while "sting" means that spring is coming, the temperature is rising, and the spring rain and warm sunshine wake up the insects hibernating in the land and caves in winter, making them break through the ground and return to nature.

In fact, people are also like this. They take off their heavy winter clothes, give up the idea of hiding in the house to resist the cold winter, and go out for an outing and exercise in spring.

Three stages of fear

Scare is divided into three stages: "When the peach blossoms first bloom; Second, wait for the sound of Cang Geng (Huang Li); Three waiting eagles turned into pigeons. " The description is mid-spring, peach blossom red, pear blossom white, orioles singing and swallows coming.

According to the general climate law, the weather in all parts of the country began to get warmer, with more rain, and most areas entered spring ploughing. When all kinds of insects dormant and hibernating in the soil are awakened, eggs in winter will also begin to ovulate. It can be seen that fright is a solar term reflecting natural phenology.
