The robin is an insect that we often see in the summer, and the hotter the weather, the happier the robin calls. But that's not what robins look like at first - they go through a process of metamorphosis from larvae to adults.

The larvae of the robin are also called young cicada monkeys, and in many places they are called? crawling chow? They live in the dark soil, where they grow to maturity before crawling out of the soil and finding a safe place to molt and become mature cicadas.

These larvae crawl out only at night, and then spend one of the most vulnerable stages of their lives, the most vulnerable. With the development of our cuisine, the larvae of the robin, are now a delicacy, seen by many as a tasty treat.

Although? crawling chow? live in the dark soil, they are able to accurately recognize the time of day, and it is during the dark night that they burrow out of the soil to molt their shells. In my personal opinion, they can accurately recognize day and night mainly because of the following reasons:

For ? The first is that the light is not a problem, but it's a problem for the people who live in the soil. This kind of, living in the soil of small insects, although the whole day living in the dark underground, but they can still clearly identify day and night.

This is because they are very sensitive to light, and for those who live underground, they can recognize day and night. Crawling chow? , also need to breathe air, so the soil is not airtight. And light can also penetrate through the gaps in the soil, sporadically.

Small animals for the changes in the external environment, itself is a lot more sensitive than we humans. For? The same is true for the The same applies to the other animals as well.

After the sun goes down, the birds' activities will stop, and the surrounding environment will slowly quiet down; even the temperature in the air is also decreasing.

It is these changing factors that set the stage for the ? creeping chow? provides the information that it is dark, making them understand that it is now safe to climb up into the trees and molt.

Every critter that survives for a long time has its own set of survival laws. So for this behavior of robin larvae, I think it is a normal phenomenon.
