This strange bug can live for a year without eating or drinking in the sand. Now it's hard to catch a kilo for a thousand yuan.

When I was a child, I grew up in the countryside. I remember that when I was a child, there was a large area of sand in the village. My father said that when he was young, it was a river. Later, after the river dried up, it became the sandy land of my childhood. In the past, the living conditions in rural areas were not as good as they are now. At that time, rural children did not have any decent toys, so they could only pick weeds in the wild, catch shrimps and crabs in the wild, and some rural children would go to that piece of sandy land. Use bags to pour water on the sand, and then build sand castles. It can be said that this sandy land is also part of the author's childhood memory.

As I often go to play in the sand, the author found a strange small animal in the sand. it can drill into the sand and make the sand everywhere with "eddies". Later, after asking my father, I know that this small animal is an insect called "sand cow".

If there is anything interesting about Sha Niu, I believe many rural children know that when there were no toys to play with at that time, many rural children would find a thin stick or bamboo stick and insert it through the center of the "whirlpool." it's very interesting.

Sand cattle like to drill sand, and their usual food sources are other insects that fall through the holes in the sand, but what if no insects happen to fall into the holes? you can rest assured that the vitality of sand cattle is very tenacious. Even if they do not eat or drink, sand cattle can live for a year, so it seems that sand cattle are more tenacious than those hibernating animals.

Sand cattle usually hide in the sand, but they wrap themselves in sand at certain seasons of the year, just like the cocoons of silkworms, wrap themselves in the sand and change into pupae, and then turn into worms and fly into the free sky. Perhaps Sha Niu's life in the sand is to save energy for himself, and when there is enough energy, Sha Niu will not be willing to hide in the desert, but to fly to the wider world. When I was a child, the author did not know these, only know that there is a sand cow to accompany the author, the author's afternoon will not be boring.

Sand cattle are the larvae of ant flies, so the nutritional value of sand cattle is very high, especially the medicinal value of sand cattle. Sha Niu plays an important role in modern medicine, and it is even more effective in treating knife wounds. It is precisely because of the medicinal value of Sha Niu that Sha Niu is now very precious, and the price of a jin of Sha Niu can be as high as several thousand yuan per jin.

However, due to the small number of sand cattle and the damage caused by people, sand cattle are even more rare now, and it is difficult to find sand cattle even if it is a few thousand yuan per jin.

Dear friends, can you still see this kind of sand cattle in the rural sand? If you see it, it must be well protected and must not be destroyed. This thing is very precious. What other secrets do you know about Sha Niu? Welcome to leave a message to share!
