Are Frogs Nocturnal? Biorhythm Explained

The animal kingdom is full of night owls, moonlight-prowling cats, and… nocturnal frogs? Yes, most frogs are nocturnal critters that prefer to sleep during the hot days that would normally overheat their ectothermic bodies. At night, they wake up to hunt, call for mates, and skip daytime predators in the poor light. For the nocturnal predators, frogs have adapted to sort of camouflage into the night grass and confound would-be assailants.

Just as important, nights are a lot cooler and a frog who may have spent the day in a warm, stuffy burrow can cool off. The night also gives frogs an advantage in the food department because insects are a lot more active at night, so they have more opportunities to fill their bellies. On the other hand, being too cool can make a frog slow down, so it’s a fine balance for them.

If you’ve ever wondered about frogs’ sleeping habits, you’re in the right place. Join us below as we explore the frogs that aren’t nocturnal, how frogs communicate at night, and whether frogs hibernate.

What Do Frogs Do at Night?

We briefly covered the basics of what frogs do at night: mate, hunt, avoid predators, and cool down. Let’s discuss those in a little more detail below so you can get a better idea of how the frog lives in the wild.


Aside from their iconic ribbet, different species of frogs may bellow or croak to try and attract mates at nighttime. Frog mating season is typically during the spring or wet season when the ground is thawing and becoming more moist. When it’s time to lay eggs, frogs prefer to lay them in slow-moving bodies of water like ponds or fens.

Frogs in the wild are carnivores that eat an array of prey animals, but the one constant is insects. Frogs can shoot their long, sticky tongue out an astonishing distance to snatch bugs out of the air, and they even have teeth designed to hold prey while they swallow it. Larger frogs can eat fish, small rodents, minnows, and even other frogs.

Evading Predators

Most of the frog’s natural predators are asleep during the night, making it the perfect time for the frog to get its business done. However, frogs still face mortal threats like snakes, owls, and foxes. That’s why they’ve evolved to better camouflage into the dark green forest, which makes predators squint really hard before they can grab a frog for lunch.

Are All Frogs Nocturnal?

Most frogs are nocturnal, but not all. A few species of frogs, most notably the tree frog and poison dart frogs, are diurnal and are most active during the day. They sport brighter colors to better match the vibrant jungle daytime and feast on daytime insects like dragonflies or butterflies. The warmth of the daytime helps these frogs stay active by raising their body temperature in contrast to cool temperatures that make frogs slow down at night.

Do Frogs Hibernate?

Yes! Frogs do hibernate in a similar way to bears during the winter. Instead of finding a suitable cave, though, frogs simply burrow down into the ground. They typically choose a sheltered location that retains warmth well, like piles of dead leaves and twigs, mud, or compost piles. It’s also important that they do not lose too much water, making moist materials preferable when possible.

Frogs are some of the most fascinating (albeit slimy) creatures in the animal kingdom, and most of them are nocturnal by nature. A few brightly colored frogs like the poison dart and tree frogs are active during the day, but they’re most definitely the exceptions rather than the rule.
