The primary diet of an insectivore consists mainly of insects. Insectivorous animals, like frogs, certain birds, and various reptiles, specialize in consuming insects as their primary source of nutrition. This diet can include a wide variety of insects, such as beetles, ants, grasshoppers, and caterpillars. Insectivores have adapted various hunting strategies and physical features, such as sticky tongues or specialized beaks, to capture their prey. This diet provides essential proteins, fats, and other nutrients, playing a significant role in the ecosystem by helping control insect populations.
