First of all, let's talk about "how does the golden cicada distinguish between wild and cultured?" Presumably, as long as my brothers and sisters who grew up in the countryside, they all caught the golden cicada when they were young. I remember that they were holding old flashlights with batteries at that time, and now they are basically charged. As long as everyone comes out to catch golden cicadas at night, it seems good. At that time, there were many golden cicadas, but now there are fewer and fewer trees. Everyone knows how to catch golden cicadas, but when it comes to how to distinguish wild cicadas from cultured cicadas, I think most of my friends are still unclear. In fact, as long as you master these two points, you can also distinguish them. For example, the first point is that the head of wild cicada is darker than that of cultivated cicada, and the second point is that the front paws of golden cicada are thicker, while those of cultivated cicada are smaller.

"Why do cicadas lay eggs in trees, but climb out of the soil?" First of all, we should know that after climbing the tree, if it is not caught by us at this stage, it will become a cicada on the tree. In our hometown, it is said that cicada can live for about 9 days, so it will lay eggs on the branches on the last day of these 9 days.

So when the golden cicada lays eggs, it is still in hot summer, so these eggs will experience autumn and winter, that is to say, when the branches wither in autumn or winter, the branches with golden cicada eggs will fall to the ground when the wind blows gently.

Another is that all the branches laid by the golden cicada will wither and slowly fall to the ground, and then these eggs will climb into the soil, so after it survives in the soil for three years, it will form a golden cicada and climb out of the ground.

"Where did the soil go when the golden cicada made the hole?" In fact, the soil when the golden cicada digs a hole can be divided into two situations. The first one is that when the golden cicada is still a larva, it will drill into the soil along some cracks in the soil, so it can't see the change of the soil at this time. The second is that when the golden cicada grows up and climbs out of the ground, the soil will usually be on the edge of the hole, so when we catch the golden cicada, we see traces of loose soil on the edge of the bean hole, so there must be a golden cicada in this hole.

Where is the earth unearthed from the Monkey Cave? Cicada crawls out of the soil by digging holes and climbing up layer by layer. When climbing up, the soil on it will be trampled by cicadas and stepped on it bit by bit. So when the cicada crawled out of the soil, we just saw a very shallow hole. Others said that cicada monkeys blocked the hole when climbing in order to protect their companions from natural enemies. This is just heard, and it has not been confirmed. Summary: Although golden cicadas lay eggs in trees, cicada monkeys in nymph stage will be sucked clean by the juice in the branches, then fall to the ground, climb into the soil and attach to the roots. Continue to suck juice and grow. So we saw the golden cicada laying eggs in the tree, but we learned that the monkey climbed out of the ground. When climbing out of the ground, the cicada's cave was sealed by the soil it had climbed down.
