predators: many different kinds of predators feed on insects. insects are an important part of the diet of many vertebrates, including birds, amphibians, reptiles, fish, and mammals. these insectivorous vertebrates usually feed on many insect species, and rarely focus on pests unless they are very abundant. insect and other arthropod predators are more often used in biological control because they feed on a smaller range of prey species, and because arthropod predators, with their shorter life cycles, may fluctuate in population density in response to changes in the density of their prey. important insect predators include lady beetles, ground beetles, rove beetles, flower bugs and other predatory true bugs, lacewings, and hover flies. spiders and some families of mites are also predators of insects, pest species of mites, and other arthropods.
