Frogs are a kind of beneficial insects, and their existence is beneficial to human beings. One of the main reasons is that frogs eat many insects that are harmful to crops. Frogs often move in farmland or paddy fields, and their main food is insects. They can eat many insects, many of which are insects that harm crops such as rice, corn and cotton. For example, rice leaf rollers, rice borer and rice mud bug, corn borer and cotton bollworm, which harm rice, can be used as food for frogs. Frogs can not only eat pests, but also eat a lot of pests.

As mentioned above, frogs can eat pests, and the number of pests they eat is very large. Frogs can eat many pests every day. Generally speaking, they can eat at least 50-60 insects every day. Some frogs can eat even more, eating more than 70 or even nearly 100 insects. Specifically, the number of pests eaten by frogs is related to their size. Frogs with larger size eat more, so they eat more pests. Generally speaking, frogs can eat nearly 10,000 or even more insects in one year, which shows that their existence is of great significance to human beings and can effectively protect crops and ensure yield.
