"bean worm" is called bean worm in my hometown. The first time I saw it was in the eighties, when I was five or six years old. The impression was shocking. In that year, soybean (soybean) field was invaded by large-scale bean worms. As long as it is soybean field, there are many bean worms ... It is no exaggeration to say that there are more than ten bean worms gnawing at bean leaves on each soybean seedling. That year, they "suddenly" appeared on a large scale, which shocked me only for fun ―― so many chubby green bugs. In those few years, there were a lot of bean bugs. In order to cope with the harm they brought to crops, the villagers began to plant other crops, and the impression of bean bugs was slowly submerged in my memory.

Last year, I went to Shandong for business, and my friends hosted me in the evening. The grasshopper skewers served were all right, but the "hot and sour bean ginseng" served surprised me again. These pests have now become delicious food! I have to admire the spirit of the foodies. But when I saw the bean ginseng, I remembered the indescribable scene of stepping on the bean worm when I was a child, and there was no desire to eat it. After repeated encouragement from friends, I ate a hot and sour bean ginseng, which was delicious. My friend also saw that I had psychological barriers to this delicious food, so I no longer "forced" me to eat this dish again. The bean worm gave me these two mental shocks, which made me curious about it. What is the "magic" of this pest that plagues crops? Let some people eat them?

Although bean worm is the natural enemy of soybean, its pulp is harmless. Bean worm has high nutritional value. It is high in protein and low in fat, and it is a natural green health care treasure for expelling cold and nourishing stomach. It is rich in seven amino acids that the human body cannot synthesize. It is an excellent high-protein food, which is delicious when cooked into dishes, and can enhance human immune function, improve human disease resistance and cancer resistance, and has special curative effects on treating stomach cold diseases and malnutrition. Bean worms enter the dish in various forms, such as stewing, making soup and frying, all of which are delicious. No wonder it can become a unique "landscape" on the dining table in some areas like locusts.
