Frogs are neither beneficial nor pests. Frogs are amphibians, not insects. But frogs are a kind of animal that is beneficial to humans and are often called the "protector of crops." They feed on insects as their main food and are the natural enemies of most agricultural pests. Frogs mainly inhabit rivers, ponds, rice fields and grass beside water, and sometimes lurk in the water.

Predation habits:

Frogs are omnivorous animals, of which plant food only accounts for about 77% of the diet; animal food accounts for about 93% of the diet. From the dissection of 60 frogs, it was found that among the animal foods, the swallowed animals involved four phyla, four classes, ten orders, and more than thirty families. Among the 156 prey animals, Insecta accounted for 80, and Lepidoptera accounted for the most: 11 rice leaf rollers, 10 rice borers, 7 rice bracts, 10 armyworms, 2 corn borers, and cotton red bolls. 2 insects, 2 ash borers, 3 Spodoptera exigua, and 5 rice-eyed butterflies. The order Coleoptera followed: 5 rice mud bugs, 6 rice weevils, 2 scarabs, and 4 ladybugs.
