Lizards are known for their diverse diets, ranging from insects to small mammals. Ants are one type of insect commonly found in lizards’ diets. However, not all lizards consume ants, and the frequency with which they do so can vary depending on the species.

Some species of lizards, such as the horned lizard, are known to have a diet that consists primarily of ants. These lizards have specialized adaptations that allow them to consume large quantities of ants, such as a wide mouth and a sticky tongue.

Other species, such as geckos, may occasionally consume ants but do not rely on them as a primary food source.

The question of whether or not lizards eat ants is interesting, as it highlights the diversity of these reptiles’ diets. While some species are known to consume ants regularly, others may only do so occasionally.

Understanding the role of ants in the diets of different lizard species can provide insight into the ecology and behavior of these fascinating animals.


Lizards’ Diet

What Lizards Eat


Lizards are known to be opportunistic predators, meaning they eat whatever prey is available to them. Their diet varies depending on the species, size, and location. Some lizards are herbivores, others are carnivores, and some are omnivores.

Carnivorous lizards feed on insects, small mammals, birds, and other reptiles. They have sharp teeth and strong jaws that help capture and kill their prey.

Some species of lizards are specialized hunters, such as chameleons, which use their long tongues to catch insects.


How Lizards Hunt


Lizards use different hunting techniques depending on their prey. Some lizards, like geckos, hunt at night, while others, like iguanas, are active during the day. Some lizards, like chameleons, are ambush predators that wait for their prey to come close before striking.

Other lizards, like monitor lizards, are active hunters that chase down their prey. They use their speed and agility to catch fast-moving prey like birds and small mammals. Finally, some lizards, like skinks, use their sense of smell to locate their prey.


Why Lizards Eat Ants


Ants are a common food source for many species of lizards. Ants are small and abundant, making them easy prey for lizards. Some species of lizards, like the horned lizard, have adapted to eat ants exclusively. Ants also provide lizards with a good source of protein, which is essential for their growth and survival.

In addition to protein, ants contain other nutrients like carbohydrates and fats, which provide lizards with energy. Some species of ants also produce formic acid, which lizards can use as a defense mechanism against predators.

Overall, lizards have a diverse diet that varies depending on their species, size, and location. For example, while ants are a common food source for many species of lizards, they also eat a variety of other prey, including insects, small mammals, and other reptiles.


Ants as a Food Source


Ants are a common food source for many lizard species. They are small and abundant, making them an easy and convenient prey item for lizards.


Ants’ Nutritional Value


Ants are rich in protein, essential for the growth and maintenance of a lizard’s body. They also contain carbohydrates, fats, and minerals such as calcium, phosphorus, and potassium.

However, ants are not a complete source of nutrition and should be supplemented with other food items to ensure a balanced diet.


Ants’ Availability


Ants are available year-round in most habitats, making them a reliable food source for lizards. They can be found in large numbers in areas such as gardens, fields, and forests. However, the availability of ants may vary depending on the season and location.


Ants’ Size and Quantity


Ants are small, making them an ideal prey item for small and medium-sized lizards. Larger lizards may consume ants in larger quantities to meet their nutritional needs. However, consuming too many ants can lead to indigestion and other health problems.

In conclusion, ants are a nutritious and readily available lizard food source. They provide essential nutrients and are abundant in most habitats. However, they should be supplemented with other food items to ensure a balanced diet.


Types of Lizards that Eat Ants

Lizards that Primarily Eat Ants


Several species of lizards primarily feed on ants. These include:

  • Ant-eating geckos (Hemidactylus frenatus)
  • Horned lizards (Phrynosoma spp.)
  • Collared lizards (Crotaphytus spp.)
  • Chameleons (Chamaeleonidae)


Ant-eating geckos are known for their ability to climb walls and ceilings, and they are commonly found in urban areas where they feed on ants and other small insects.

Horned lizards are native to North America and are known for their unique appearance, which includes a crown of horns on their head.

Collared lizards are found in the southwestern United States and Mexico, known for their bright colors and fast movements.

Chameleons are found in tropical regions worldwide and are known for their ability to change color.


Lizards that Occasionally Eat Ants


Some lizards will consume ants as part of their diet, but they do not primarily rely on them for sustenance. These include:

  • Bearded dragons (Pogona spp.)
  • Green iguanas (Iguana iguana)
  • Anoles (Anolis spp.)

Bearded dragons are popular pets and are known for their docile nature. They are native to Australia and occasionally eat ants as part of their diet.

Green iguanas are also popular pets native to Central and South America.

They will eat ants but primarily feed on leaves and other vegetation. Anoles are small lizards found in the Caribbean and southern United States.

They will eat ants but feed on other insects and small invertebrates.


Lizards that Eat Ants Along with Other Prey


Many lizards will eat ants as part of a varied diet, including other prey items. These include:

  • Skinks (Scincidae)
  • Monitor lizards (Varanidae)
  • Gila monsters (Heloderma suspectum)


Skinks are a diverse group of lizards found around the world. They will eat ants but feed on other insects, small vertebrates, and plant matter.

Monitor lizards are large lizards found in Africa, Asia, and Australia. They are known for their intelligence and will eat ants and other prey like birds, rodents, and other lizards.

Gila monsters are venomous lizards found in the southwestern United States and Mexico. They will eat ants but primarily feed on eggs and small mammals.

In conclusion, many types of lizards eat ants, with some species relying on them as a primary food source and others consuming them as part of a varied diet.


Ants’ Defense Mechanisms


Ants are known for their ability to defend themselves against predators. Therefore, they have developed various defense mechanisms to protect themselves and their colony. These mechanisms can be classified into chemical, physical, and swarm defense mechanisms.


Chemical Defense Mechanisms


Ants have evolved to produce chemicals that can deter or even harm predators. For example, they can spray formic acid, which can cause irritation and pain to predators.

Some ants also produce alkaloids, which can be toxic to predators. These chemicals can be found in the ants’ venom sacs and delivered through their stingers or mandibles.


Physical Defense Mechanisms


Ants have also developed physical defense mechanisms to protect themselves. For example, some ants have evolved to have hard exoskeletons that can withstand predator attacks. They can also use their mandibles to bite and hold onto predators. In addition, some ants have spines on their bodies that can deter predators from attacking them.


Ants’ Ability to Swarm


Ants’ ability to swarm is also a defense mechanism. When threatened, ants can quickly gather and swarm around the predator. The swarm can overwhelm the predator and cause confusion and disorientation. The swarm can also bite and sting the predator, causing pain and irritation.

In conclusion, ants have developed various defense mechanisms to protect themselves and their colony from predators. These mechanisms include chemical, physical, and swarm defense mechanisms. These mechanisms can make it difficult for predators like lizards to prey on ants.




In conclusion, lizards do eat ants. While not all species of lizards feed on ants, many do. Some species, such as the horned lizard, have even evolved specialized adaptations to consume ants. In addition, lizards are known to eat a variety of insects and other small prey, and ants are just one of the many options available to them.

It is important to note that while lizards eat ants, they do not rely solely on ants as their primary food source. Instead, ants are often consumed as a supplement to their regular diet, which may include other insects, spiders, and even small vertebrates.

Overall, the relationship between lizards and ants is complex and varied. While some lizards may actively seek out ants as a food source, others may avoid them altogether. Therefore, it is essential to consider the specific species of lizard and their natural habitat and diet when discussing their feeding habits.
