If you’ve spotted a lizard darting through your flower beds, you might wonder what do garden lizards eat. These small reptiles are actually beneficial visitors, helping with pest control by consuming a varied menu of small insects and arthropods.
Understanding their diet helps you appreciate their role and even support them in your yard. This guide covers everything from their favorite foods to how they hunt.
You’ll learn what to expect and how to create a lizard-friendly habitat.
What Do Garden Lizards Eat
Garden lizards are primarily insectivores, meaning their diet consists almost entirely of insects. Their specific menu changes with their life stage, the time of year, and what’s available in your local environment.
An adult lizard’s diet is diverse and opportunistic. They are not picky eaters and will consume most small creatures they can overpower.
Primary Insect Prey
The bulk of a garden lizard’s calories come from common garden insects. These pests are exactly why lizards are so valuable to gardeners.
- Crickets and Grasshoppers: A staple food source, providing good protein and often being abundant.
- Beetles: Including weevils, ladybugs (less commonly), and various ground beetles.
- Ants: While small, ants are consumed in large quantities, especially by smaller lizard species.
- Moths and Butterflies: Lizards will eat both the adult fliers and their caterpillar larvae, which are often garden pests.
- Flies and Mosquitoes: Lizards are excellent at snatching these flying insects out of the air or from surfaces.
- Aphids and Leafhoppers: These tiny, soft-bodied insects are easy prey, especially for young lizards.
Other Common Food Sources
Beyond insects, garden lizards will eat other small invertebrates. This broader category of food is known as arthropods.
- Spiders: Many lizards readily consume web-building and hunting spiders.
- Earthworms: A nutritious and soft-bodied option, often eaten after a rain.
- Snails and Slugs: Some larger lizard species will consume these, shell and all.
- Pill Bugs and Sow Bugs (Roly-Polies): Common in moist, damp areas of the garden.
Do Garden Lizards Eat Plants Or Fruits
This is a common question. The vast majority of common garden lizards are strictly carnivorous as adults. They do not eat leaves, flowers, or vegetables.
However, there are a few important exceptions and clarifications. Some omnivorous lizard species, like certain skinks, may occasionally consume soft fruits, berries, or flower petals, but this is a very small part of their diet.
More importantly, a lizard might be seen licking soft, overripe fruit. They are not eating the fruit itself but are attracted to the sugar and the small insects, like fruit flies, that are feeding on it.
The Diet Of Baby Garden Lizards
Baby lizards, often called hatchlings, have the same dietary preferences as adults but on a much smaller scale. Their tiny size limits what they can catch and swallow.
They primarily hunt for very small, soft-bodied insects. Their survival depends on an abundance of tiny prey like aphids, fruit flies, springtails, and small spiderlings.
This is one reason why pesticide use can be devastating to lizard populations, as it removes this crucial food source for young lizards.
How Garden Lizards Hunt and Feed
Understanding their hunting methods shows just how adapted they are for pest control. Most garden lizards use a strategy known as “sit-and-wait” predation.
Patience And Precision
A lizard will often find a sunny perch on a rock, fence post, or low branch. From here, it remains perfectly still, using its excellent vision to monitor for movement.
When an unsuspecting insect comes within range, the lizard springs into action with incredible speed. It uses its long, sticky tongue to snatch the prey and pull it into its mouth.
Some species, like anoles, are known for their acrobatic leaps to catch flying insects. Their hunting is a constant, silent service in your garden.
Digestion And Water Intake
Lizards need warmth to digest their food. This is why you see them basking in the sun for long periods; they are raising their body temperature to process a meal.
They get most of their water from the insects they consume. However, they will also drink water droplets from leaves, soil, or the edges of puddles. Providing a shallow water source can help them during dry spells.
Seasonal Changes in Lizard Diets
A lizard’s diet isn’t static; it shifts with the seasons based on temperature and insect availability.
Spring And Summer Feeding Frenzy
These warm months are peak activity time. Insects are plentiful, and lizards feed heavily to build energy reserves. Their metabolism is high, and they may eat multiple times a day.
This is when they do the majority of their pest control work, targeting caterpillars, beetles, and grasshoppers that are actively damaging plants.
Fall And Winter Slowdown
As temperatures drop, insect activity plummets. Lizards are cold-blooded, so their metabolism slows dramatically.
In colder climates, they enter a state of brumation (similar to hibernation). They eat very little or nothing at all, living off fat stores. In warmer regions, they may remain active but hunt less frequently, taking whatever scarce prey they can find.
Creating a Lizard-Friendly Garden
If you want to encourage these natural pest controllers, you can make your yard more inviting. A healthy lizard population means fewer chemicals are needed.
Provide Food Sources Naturally
The best way to provide food is to cultivate a diverse, insect-friendly garden. Avoid using broad-spectrum insecticides, as these poison the lizard’s food supply and can kill the lizards directly if they eat contaminated insects.
Plant native flowers and shrubs to attract a variety of insects. A slightly “wild” area with leaf litter and logs will harbor plenty of beetles, spiders, and pill bugs for lizards to eat.
Offer Shelter And Basking Spots
Lizards need places to hide from predators and the elements. They also need sunny spots to warm up.
- Leave piles of rocks or broken pottery in sunny areas.
- Stack some firewood loosely in a dry spot.
- Plant dense, low-growing ground cover.
- Allow a few flat, sun-warmed stones to remain in your garden beds.
Ensure Water Access
A shallow dish of water with gently sloping sides or a pebble-filled basin is perfect. Place it near shelter so lizards feel safe approaching. Change the water regularly to prevent mosquito breeding.
What Not to Feed Garden Lizards
It can be tempting to offer food to lizards, but it’s usually best to let them hunt naturally. If you do choose to supplement, you must know what is safe.
Foods To Avoid Completely
- Processed Human Food: Bread, cheese, lunch meat, etc. Their digestive systems cannot process these.
- Fireflies (Lightning Bugs): These are highly toxic to most lizards and can be fatal if ingested.
- Wild-Caught Insects from Unsafe Areas: Insects caught near roads or treated lawns may have pesticides or pollutants on them.
- Large, Aggressive Prey: Avoid offering large crickets or insects that could injure the lizard in a fight.
If You Choose To Supplement
If you want to feed a lizard that frequents a specific spot, small, store-bought crickets or mealworms are acceptable. These are raised as pet food and are free of pesticides.
Dust the insects with a calcium supplement powder to ensure the lizard gets proper nutrition. Place the insects near the lizard’s basking area, but let the lizard catch them itself to maintain its natural instincts.
Common Garden Lizard Species and Their Diets
While their diets overlap, different species may have slight preferences. Here’s a look at a few common ones.
Anoles (The American Chameleon)
These small, green or brown lizards are avid hunters of flying insects. They are often seen on fences and walls, staring down prey. Their diet is almost exclusively small, soft-bodied insects like flies, moths, and spiders.
Skinks
With their smooth, shiny scales, skinks often forage in leaf litter. They have a slightly broader diet, eating beetles, caterpillars, crickets, and even the occasional earthworm or fallen berry.
Alligator Lizards
These larger, more robust lizards are powerful predators. They will tackle bigger prey, including large insects, snails, slugs, and even other small lizards. They are particularly good at consuming garden pests with hard shells.
Fence Lizards
A common sight on wooden structures, fence lizards are classic sit-and-wait predators. They consume a huge number of ants, beetles, and spiders, making them excellent for general garden pest control.
Frequently Asked Questions
Do Garden Lizards Eat Mosquitoes?
Yes, they certainly do. Lizards will eat both adult mosquitoes and their larvae if they can access them in standing water. While they are not a sole solution for mosquito control, every little bit helps.
What Do Backyard Lizards Drink?
Lizards primarily get moisture from their prey, but they will drink water droplets from surfaces. They prefer to drink from condensation on leaves or shallow puddles rather than deep water sources.
How Often Do Lizards Need To Eat?
An active adult lizard in warm weather may eat several insects each day. Younger, growing lizards need to eat more frequently. During cooler weather, their feeding slows down or stops entirely.
Are Lizards Good For My Garden?
Absolutely. They are a sign of a healthy ecosystem. By consuming herbivorous insects, they protect your plants naturally. Encouraging lizards reduces the need for chemical pesticides.
What Eats Garden Lizards?
Lizards are prey for many animals, including birds, snakes, larger lizards, cats, and rodents. Providing good shelter like rock piles and dense brush helps protect them from predators.
Garden lizards are efficient, natural partners in maintaining your garden’s health. By understanding what do garden lizards eat, you can appreciate their role as pest control agents. Their diet of insects directly targets many common problems you face.
