Green frogs are mainly carnivores, and they feed on various insects and aquatic and terrestrial invertebrates, including slugs, snails, flies and crayfish. They also eat butterflies, caterpillars, moths and spiders.
Green frogs are fist-sized frogs with an outer color that ranges from green to yellowish-brown. They usually catch food by sitting and waiting in the water or by the shore until their prey comes near. They eat throughout the day and at night as well.
They consume a wide selection of invertebrates, such as beetles, grasshoppers, crustaceans and molluscs. Moreover, their diet consists of fairy shrimp, water striders, whirligig bugs and backswimmers. Green frogs also sometimes eat vertebrates, particularly small snakes and other frogs. Terrestrial beetles are their primary source of food. Green frog tadpoles feed on diatoms, algae and tiny organisms, such as zooplankton.
Green frogs thrive in freshwater habitats, such as streams, ditches, lakes and ponds. Young frogs tend to scatter into meadows and wooded regions when it is rainy. Except for the breeding season during which the frogs gather together, green frogs often live in solitude. While these frogs are active during day and night, they turn dormant when the weather is cold. During winter, green frogs typically hibernate at the muddy bottom of bodies of water.
