[citation needed] Capable swimmers, skinks have been known to dive under water to evade predators and remain submerged for several minutes until a threat has passed.

[citation needed] The common garden skink feeds on invertebrates, including crickets, moths, slaters, earthworms, flies, grubs and caterpillars, grasshoppers, cockroaches, earwigs, slugs, dandelions, small spiders, ladybeetles and many other small insects, which makes it a very helpful animal around the garden.

[citation needed] The common garden skink relies purely on the movement of its prey when hunting.

Once it has had one meal, it begins to actively pursue prey for a short while with its newfound energy[citation needed].

[3][failed verification][better source needed] Although L. guichenoti is often seen under leaves, in long grass and under rocks so that it can watch its prey, it also often prefers hiding in logs where its larger predators cannot reach it.

As with most reptiles, the common garden skink is cold-blooded, and may be seen on top of rocks or paths in the morning trying to warm its blood.

The disconnected tail will twitch vigorously for a while, capturing the attention of the predator while the lizard makes its escape.

[citation needed] The common garden skink is oviparous[1] and lays small white eggs between summer and mid autumn.
