Do Lizards Eat Flies

Lizards are the rockstars of the animal kingdom! They’re not just fascinating, but their unique appearance and behavior are sure to leave you amazed. These little creatures come in a wide range of shapes and sizes and can be found in various habitats all over the world. Now, let’s talk about the juicy stuff – what do these rockstars eat? One of the most common questions people have about lizards is their dietary habits. Brace yourselves, because while the answer can vary depending on the species, many lizards do have a taste for flies!

Flies are a common food source for many insectivorous lizards, such as chameleons, geckos, and anoles. These lizards are known for their ability to catch fast-moving prey, and flies are often an easy target. In the wild, lizards will hunt for flies and other insects by waiting patiently for them to fly by, or by actively chasing them down. As pets, many lizards can be fed a diet of live or pre-killed insects, including flies.

Do Lizards Eat Flies?

Yes, lizards do eat flies. In fact, flies are one of the common insects consumed by insectivorous lizards. Other insects that lizards consume include crickets, grasshoppers, ants, termites, and moths. Some lizards also eat invertebrates like snails and slugs.

It’s important to note that not all lizards eat flies.

While some species of lizards are known to eat flies, not all lizards have the same feeding habits. Some species of lizards, such as bearded dragons and iguanas, are herbivores and do not eat flies or other insects. Other species, such as monitor lizards and some skinks, are carnivores and may eat a variety of prey, including insects, but may not specifically target flies.

When it comes to pet lizards, flies may not be the best choice of food. Flies caught in the wild may carry diseases or parasites, which can be harmful to your pet lizard. Instead, it’s best to feed your pet lizard commercially-raised insects or insects that you have raised yourself. This will ensure that the insects are safe and free from harmful substances.

Types of Lizards That Eat Flies


Geckos are a type of lizard that are commonly kept as pets. They are known for their sticky feet and ability to climb walls and ceilings. Geckos are also insectivores, which means that they primarily eat insects. Some species of geckos that eat flies include leopard geckos and house geckos. These lizards have a voracious appetite for flies, and will readily consume them when they are available.


Chameleons are another type of lizard that are known for their unique ability to change colors. They are also insectivores and commonly eat insects such as flies, crickets, and grasshoppers. However, due to their environment, which can be food-scarce, they will also opportunistically consume vegetation.

Chameleons are fascinating creatures that require specialized care. If you are considering getting a chameleon as a pet, it is important to do your research and make sure that you are prepared to provide them with the care they need.


Anoles are a type of small lizard that are commonly found in the southeastern United States. They are insectivores and feed on a variety of small insects, including flies. Anoles are also popular as pets and can make great additions to a household.

If you have an anole as a pet, it is important to provide them with a varied diet that includes a variety of insects. In addition to flies, anoles also eat crickets, mealworms, and other small insects. Providing your anole with a varied diet will help ensure that they receive all the nutrients they need to stay healthy.

Benefits of Eating Flies for Lizards

While many people may find it gross, lizards actually benefit from eating flies. In this section, we will explore the different benefits of consuming flies for lizards.


Flies are a great source of protein for lizards. Protein is essential for building and repairing tissues, and for maintaining a healthy immune system.

In addition to protein, flies are also rich in other essential nutrients that lizards need to stay healthy. Flies contain vitamins, minerals, and other nutrients that can help to improve a lizard’s overall health and wellbeing. For example, flies are a good source of calcium, which is important for maintaining strong bones and teeth.


Believei it or not! Flies also contain a lot of water, which can help to keep lizards hydrated. Lizards need to stay hydrated in order to maintain their body temperature and to prevent dehydration. Eating flies can help to supplement a lizard’s water intake, especially if they are not drinking enough water on their own.

Overall, while it may seem strange to us, eating flies is actually very beneficial for lizards. Flies provide lizards with the protein, nutrients, and hydration they need to stay healthy and strong.

Also, Do not overfeed your lizard flies, as this can cause digestive problems and other health issues.

If you are unsure about the safety of feeding your lizard flies, consult with a veterinarian or reptile specialist.

Overall, whether in the wild or as pets, lizards play an important role in controlling the populations of insects and other small creatures.

But let’s be real, the best part about all of this is imagining a little lizard with its sticky tongue shooting out to catch a fly mid-air. It’s like a scene straight out of a superhero movie!
