In this article, we will dive deep into the diet of common garden skinks, uncovering their eating habits, nutritional needs, and the benefits they provide to gardeners.
An Introduction to Common Garden Skinks
Common garden skinks, known scientifically as Lampropholis guichenoti, are small lizards native to Australia and New Zealand. They are prevalent in a variety of environments, including gardens, forests, and grasslands. Typically ranging from 10 to 15 centimeters in length, these skinks are characterized by their smooth, shiny scales and slender bodies. They can exhibit a variety of colors, but are most often seen in shades of brown or black, with distinctive stripes running down their backs.
Understanding their diet is crucial, as it does not only affect their survival but also plays a significant role in the ecosystem. Garden skinks primarily feed on small insects, but their dietary preferences can be quite diverse.
The Diet of Common Garden Skinks
At the core of a common garden skink’s diet are small invertebrates. However, their diet can vary based on availability, season, and individual preferences. Below are the primary food sources for these skinks.
Insects
Insects constitute the bulk of a common garden skink’s diet. These lizards are opportunistic feeders, meaning they consume whatever they can find and capture. Here are some common insects that skinks typically feast on:
- Ants
- Beetles
- Crickets
- Grasshoppers
- Moths
Insects are rich in protein and provide essential nutrients for the skink’s growth and development. Skinks rely heavily on insects not only for nourishment but also for hydration, as they can obtain moisture from their prey.
Other Invertebrates
Apart from insects, common garden skinks can also consume a variety of other invertebrates. Some of these include:
Spiders
Spiders make up part of the skink’s diet. These creatures are abundant in garden environments, allowing skinks to readily hunt them down. The proteins and fats found in spiders are crucial for the lizard’s energy needs.
Earthworms
While less common in the skink’s diet, earthworms are sometimes eaten, especially when other food sources are scarce. These worms are nutritious and provide a good source of moisture.
Snails and Slugs
Although more challenging to catch due to their slimy nature, snails and slugs can also be consumed by garden skinks. They offer a different texture and flavor, which may encourage skinks to vary their diet.
Seasonal Variations in Diet
The diet of common garden skinks can differ significantly with the changing seasons. They tend to thrive and feed more actively during warmer months when insect populations are at their peak. As temperatures drop in winter, skinks’ activity levels and feeding habits slow down considerably.
Summer Feeding Patterns
During the warmer summer months, skinks are more active and hunt frequently. The abundance of insects and other invertebrates means they can consume all kinds of food, focusing mostly on high-protein insects that support their energy needs.
Winter Adaptations
In winter, food may become scarce, leading to behavioral adaptations in skinks. They may enter a state of brumation, a hibernation-like state. During this time, their metabolism slows, and they may reduce their feeding frequency significantly. They rely on their fat reserves until spring returns and food becomes abundant once again.
Feeding Habits and Hunting Techniques
Common garden skinks employ various feeding strategies and hunting techniques. Their agility and keen eyesight help them actively hunt for prey in gardens.
Foraging Behavior
Skinks are known to forage actively for food as they roam around their territory. They often hide among leaves, rocks, or branches, waiting for unsuspecting prey to pass. This ambush strategy allows them to conserve energy while maximizing their chances of a successful hunt.
Active Hunting
At times, skinks will actively chase down their prey. Being quick and nimble, they can dart rapidly to catch fast-moving insects. Their speed is one of their greatest advantages, allowing them to capture even the most elusive of insects.

By preying on various insects, they reduce the likelihood of infestations that could harm plants. This natural pest control minimizes the need for chemical pesticides, promoting a healthier garden environment.
Soil Health
As skinks feed on earthworms and other soil-dwelling organisms, they also contribute to soil health. Their predation helps maintain the balance of organisms in the soil, promoting nutrient cycling and improving soil structure.
Biodiversity Promotion
The presence of common garden skinks is indicative of a biodiverse garden ecosystem. Their diet also reflects the health of the environment; a diverse array of food sources leads to healthier skinks, which in turn supports the larger food web in your garden.
Attracting and Providing for Garden Skinks
If you’d like to attract common garden skinks or encourage their presence, there are several strategies you can implement. Offering a conducive habitat can help ensure these lizards thrive.
Creating a Suitable Habitat
Tucking away natural hiding spots with rocks, logs, and dense ground cover can provide the shelter skinks need to thrive. A garden rich with vegetation allows skinks to evade predators and hunt more effectively.
Minimizing Pesticide Use
To keep skinks safe and healthy, minimize chemical pesticide usage in your garden. Opt for organic alternatives or natural pest control methods to ensure a safe environment where skinks can flourish.
Providing Water Sources
Creating small, shallow water sources can offer hydration opportunities for skinks, especially during dry spells. Birdbaths or small dishes filled with pebbles and water can be ideal.
Conclusion
In conclusion, the common garden skink is a remarkable creature that plays an integral role in a thriving garden ecosystem. With a diet primarily consisting of insects and various invertebrates, these agile lizards contribute to natural pest control, soil health, and biodiversity. By nurturing an environment conducive to their needs, gardeners can benefit from the ecological contributions of these beneficial reptiles.
Understanding what garden skinks eat not only illuminates their fascinating dietary habits but also emphasizes their importance in promoting a balanced and healthy garden. So, the next time you spot a skink gliding across your garden, remember the critical role they play in the intricate web of life that your garden supports.
What do common garden skinks eat?
Common garden skinks primarily consume a diet consisting of insects and other small invertebrates. They are particularly fond of small crickets, beetles, and ants, which are readily available in their natural habitats. In addition to insects, they may also eat spiders and other tiny arthropods that they can catch and subdue.
It’s important to note that garden skinks have a carnivorous diet, reflecting their predatory nature. They hunt and forage in leaf litter, on the ground, and among low-lying vegetation, which allows them to effectively catch their prey. Their agility and quick reflexes aid in their ability to capture a variety of small creatures.
How does the diet of common garden skinks vary by season?
The diet of common garden skinks can change with the seasons, reflecting the availability of prey.
