What Types of Insects Do Lizards Eat?

Lizards are fascinating creatures with specialized dietary requirements. Most lizards are insectivorous, which means they love a diet of bugs. Here are some common insects you can feed your lizard.


Most lizards love crickets. They’re a great source of protein and micronutrients, and they’re easy to “gut-load.” Crickets jump and run around the terrarium, stimulating your lizards’ natural hunting instincts.


Another big favorite but feed them to your scaly buddy in moderation. They have a high fat content, and they’re easy to store for an occasional treat. Mealworms should be gut-loaded and dusted with calcium to ensure maximum nutritional potential. Their hard exoskeleton can be challenging for some lizards to digest, so give them to your pet sparingly.

Insight Into the Nutritional Demands of Lizards

Dubia Roaches

High in protein and easy to digest. Dubia Roaches have a softer exoskeleton than other feeder insects, which makes them a great option for lizards of any species or size. Plus, they’re less likely to escape your lizard’s enclosure. Their long lifespan and ease of care make them favorites for many lizard owners.


Another worm with a high fat content, lizards go wild for waxworms. They find them highly palatable, and they’ll gorge on them, making them great to coax picky eaters or for a good shot of quick energy. However, the high-fat content means feeding your lizard to many of them could lead to obesity issues. They’re excellent for an occasional treat or as a reward.


Like mealworms, these bugs have a higher protein content. They’re very active, encouraging natural hunting behavior. These insects need to be gut-loaded and dusted with calcium, just like mealworms. They’re best for adult lizards.


Very nutritious and full of moisture. Characterized by their bright green color, lizards find them attractive. They grow fast, so feed them to your scaly friend when they’re small.


High in protein and low in fat. Silkworms are highly nutritious and easily digestible for lizards. They are soft-bodied and pose minimal risks of causing gut problems compared with the harder exoskeletons of other insects.

The Importance of Correct Nutrition for Your Lizard
