No matter what your chosen amphibian species is, it is important to do some basic digging into their dietary habits. After all, you want to be sure that you’re providing them with the right types and amounts of food.
This becomes even more complicated when you consider that certain amphibians may have evolved to be omnivores – or even primarily herbivores – and therefore need a different diet than those that are strictly carnivores or insectivores.
So, what about frogs? Are they omnivores? Let’s take a closer look.
Are Frogs Omnivores?
Yes, frogs are indeed omnivores which means that these amphibians will typically eat whatever they can find that’s small enough to fit in their mouths. This includes plants, insects, spiders, worms, and even smaller amphibians.
The term “omnivore” refers to the broad diet of these animals, which encompasses both plant and animal matter although most species of frog will only resort to eating plants in the absence of anything else, so seasonality and the scarcity of food can play a part of when and what they eat.
There are some species of frogs that are almost strictly insectivorous (carnivores that eat insects) but even those will still be considered life-history omnivores due to their eating habits when they were very young.
Note: A frog’s stomach is not too dissimilar to a human’s – it is able to break down and extract nutrients from both plant and animal matter.
What is a Life History Omnivore?
A life history omnivore is an animal that occupies multiple trophic levels across its lifetime and consumes both plant and animal material depending on what stage of its life cycle it is at.
This could mean that an animal begins life as a herbivore, feeding on plants and fruits as a juvenile and then becoming a carnivorous predator as an adult and therefore eating other animals.
Life history omnivores are often found in changes in environmental conditions, such as when new foods become available or old foods become scarce, which can cause these animals to switch what they eat.
Studies have shown that life-history omnivores tend to be more adapted to their environment and therefore less likely to go extinct when faced with environmental change.
Note: Frogs, geese, and almost all insects can be considered life-history omnivores.

What Do Tadpoles Eat?
Initially, when the tadpoles emerge, they are strictly herbivorous, feeding on algae and other plant material that they can find. This is due to the tadpole not yet having teeth and the algae is soft making it easy to eat and digest.
As the tadpoles grow and age, they start to develop tiny teeth and begin to hunt small animals making them carnivores. They will often start with dead animals and insects found around the pond’s surface although if food is scarce, they have been known to become cannibalistic and eat each other.
Eating animals at this stage of their life cycle helps them absorb a high amount of protein which helps them grow faster and mature.
What do Frogs Eat?
Although they are omnivores, adult frogs are typically carnivorous, meaning that their diet consists mostly of meat and while the diet of adult frogs may vary depending on their geographical location, most adult frogs consume a diet that is primarily composed of insects.
Some larger species of frogs will also supplement their diets with different animals, such as small rodents, fish, and even other amphibians.
Frogs are generally opportunistic feeders and will consume whatever prey is available and easily catch. The specific diet of a given species may vary depending on the local ecosystem and what food items are most abundant.
For example, if a frog subsists primarily on ants, it may switch to eating more slugs if the ants become scarce.
Note: Frogs kept as pets usually have a diet of commercially available frog pellets or live insects such as crickets.
Are All Frogs Carnivorous?
Yes, all species of frogs are carnivorous, but they are not strictly carnivores, they are in fact omnivores meaning that they will not only eat other animals, but they will also eat plant material too.
The majority of frog species are considered insectivorous meaning their diet consists primarily of insects. There is, however, one species of frog (Izecksohn’s Brazilian tree frog) that is primarily a frugivore meaning that its diet consists primarily of fruit and plant material.
All frog species, including those that are generally considered insectivores and those that are primarily frugivores, are still classed as omnivores as they will eat whatever they can in order to survive.
So, are frogs omnivores? Yes! Frogs are primarily opportunistic predators, but they will eat whatever is needed in order to survive depending on what food source is available and that includes plants. They have a varied diet that helps them thrive in many different environments.
Frogs are one of the most diverse and widespread vertebrate groups on Earth. They can be found on every continent with the exception of Antarctica, and in nearly every type of habitat, from rainforests to deserts.
This has made them one of the most successful and adaptable amphibian groups on the planet, and also one of the most important for maintaining healthy ecosystems.

“Frogs absorb water through their skin (osmosis) so they do not need to drink!”
“The biggest frog in the world is the Goliath Frog which can reach up to 35cm and weigh up to 3.3kg!”
“In English, a group of frogs is traditionally called an army although in Spanish they are known as a tropa (troop)!”
“There glass frog, found in the rainforests of Central America has translucent skin – that means that you can see through it to its insides!”
Are all frogs herbivores?
While it is true that all frogs do in fact eat plants, they cannot be classified as strictly herbivores because they also eat meat. This makes frogs omnivores because they will eat anything that is available to them.
What do pet frogs eat?
There are a variety of foods that pet frogs can eat, and the best diet for your frog will depend on the specific species. In general, most frogs will be carnivores or insectivores, so their diet should consist primarily of protein-rich foods like crickets, worms, and other small insects. Some species of frog may also enjoy eating small fish or tadpoles. If you are unable to keep any live food sources for your pet, commercially available frog pellets can also be fed to your frog.
Are any frogs vegetarian?
At a frog’s earliest stage of life (tadpole), they primarily consume vegetation making them herbivores; however, as they grow older and develop into frogs, their diet broadens to include small insects and other invertebrates. While the majority of adult frogs are opportunistic carnivores, making use of whatever prey is available, there is a small percentage of frogs – between 1 and 5 percent depending on the source – that maintain a primarily vegetarian lifestyle as adults although they will eat meat if required.
Are frogs strictly carnivorous or do they also eat plants?
Frogs are omnivores, which means they eat both plants and animals. Some species of frogs will eat vegetation, fruits, and flowers as well.
What is the best food to feed a frog?
The best food to feed a frog will depend on the species of frog. For most species, a diet of crickets, worms, and other small insects is appropriate. Some species may require specific foods such as fruit flies or small fish.
Can frogs eat mealworms?
Yes, most frogs can eat mealworms as a dietary staple, but it’s not recommended to feed them exclusively.
Can frogs eat store-bought reptile food?
Some frogs can eat store-bought reptile food, but it’s important to check the ingredients and make sure it is appropriate for the species of frog you have.
How often should I feed my frog?
The frequency of feeding will depend on the species of frog and its age. Adult frogs typically should be fed once or twice a week, while young frogs may need to be fed more frequently.
Can I feed my frog fruits and vegetables?
Some frogs may eat fruits and vegetables, but it’s not typically a significant part of their diet. It’s important to research the specific dietary requirements of the species of frog you have.
Can frogs eat live or frozen food?
Both live and frozen food can be fed to frogs, but it’s important to thaw frozen food properly before feeding it to the frog.
Can a frog eat human food?
Frogs should not be fed human food as it may not provide the necessary nutrients for their diet.
Is there a difference in diet between wild frogs and pet frogs?
The diet of wild frogs may differ from that of pet frogs, as wild frogs have access to a wider variety of food sources. Pet frogs should be fed a diet that closely mimics their natural diet, appropriate for their specific species.
Hi, I’m Stuart and I’ve had reptiles for as long as I can remember. When I was younger, I studied for a master’s in Herpetology. Over the years I have worked at several zoos before opening my very own reptile sanctuary. In my spare time, I run this website – which is a resource for people who want to learn more about their little beasties.
