Frogs have a varied diet that primarily consists of live prey, which they catch using their long, sticky tongues. Their diet depends on their species, size, and life stage:

• Adult Frogs: They mainly eat a wide variety of insects such as flies, moths, crickets, grasshoppers, ants, beetles, caterpillars, spiders, snails, slugs, worms, and larvae. Larger frogs can also eat small reptiles, amphibians (including other frogs and salamanders), small fish, small birds, and even small mammals like mice

• Tadpoles (Baby Frogs): Tadpoles are mostly herbivorous or omnivorous, feeding on algae, aquatic plants, phytoplankton, and sometimes small insect larvae or even smaller tadpoles. As they metamorphose into froglets, their diet shifts toward carnivory, eating small insects and other tiny prey

• Aquatic Frogs: Their diet includes aquatic invertebrates such as bloodworms, brine shrimp, blackworms, and commercially made frog pellets containing fish meal

In captivity, pet frogs are typically fed gut-loaded (nutrient-enriched) insects like crickets, mealworms, waxworms (in moderation), locusts, and earthworms, often dusted with calcium and vitamin supplements to meet their nutritional needs

. Frogs will generally only eat live prey that moves, as they rely on movement to trigger their feeding response. They do not eat fruits, vegetables, or human food scraps, and wild-caught insects should be avoided due to pesticide risks

. In summary, frogs are carnivorous predators that eat mostly insects and other small animals, with diet variations depending on their life stage and environment. Tadpoles start with plant-based diets and shift to carnivory as they mature
