Garden lizards in the wild typically eat snails, insects and caterpillars. In captivity, garden lizards have a diet that mainly consists of crickets and other small bugs .
Every lizard species has unique dietary needs, because lizards are a group of reptiles spanning up to 6,000 species rather than a single species. Potential pet owners should research their species' dietary needs before bringing home an animal.
Common lizards feed on insects, such as flies, grasshoppers and spiders, according to the Surrey Amphibian and Reptile Group. They also eat invertebrates, including earthworms, small snails and centipedes.
Small lizards can be carnivorous, herbivorous or omnivorous. Small lizards may eat a variety of insects, plants or a mixture of the two. Most lizards have a high metabolic rate and need to eat several times a week.
There are many lizards that are herbivorous and exclusively eat plants, while there are also some lizards that are omnivorous or carnivorous. Most pet lizards are omnivorous and need a variety of food including plants, insects and fruit to meet nutritional requirements.
The lizard has a wide variety of predators, including birds, snakes and even other lizards. When being chased or attacked by predators, lizards may swell up, hiss, break off their tails to escape or even change colors to blend in with their surroundings.
Baby lizards are able to eat the same things that adult lizards eat, so no special diet is required for babies. The diet of a baby lizard is dependent on the diet of its species.
California lizards eat mostly ants, grasshoppers, spiders and beetles. They have a small row of teeth on each jaw and teeth on the roof of their mouths. Lizards snatch their food with long, sticky tongues, crush it in their jaws and swallow it with very little chewing.
Brown lizards, or anoles, are insectivores that eat crickets, mealworms, moths, cockroaches, grasshoppers, waxworms and other arthropods. In the wild, brown lizards may eat other lizards, lizard eggs, aquatic arthropods and small fish.
Lizards are distributed throughout the world, and as the San Diego Zoo notes, most of them live on the ground. Other common lizard dwelling places are underground burrows (especially in deserts), under rocks, marshy bogs and in trees.
