Nutritionists believe that caterpillars and grasshoppers are rich in protein, which can supplement the human body's protein needs. In the eyes of bacteriologists and virologists, living caterpillars carry a lot of bacteria and viruses, which is a great potential danger.
Chinese medicine believes that some insects can be used as medicine to treat diseases. From the chemist's point of view, caterpillars are just products of protein and fat, but biologists don't think so. From their point of view, caterpillars have evolved amazing functions to adapt to the environment.
You see, this is the way of the world. It is just a caterpillar, and experts and scholars in various fields have different opinions and even contradict each other, not to mention the vast world knowledge.
