Lampropholis delicata
The delicate skink, Lampropholis delicata, is a small, diurnal lizard native to Eastern Australia, known for its color dimorphism and smooth scales. It inhabits a variety of moist environments, including woodlands, heaths, and rainforests, and has become an invasive species in New Zealand and Hawaii, often found in suburban gardens. This skink is an opportunistic insectivore, preying on spiders, bees, larvae, and termites, and is notable for its ability to shed and regenerate its tail as a defense mechanism.

About Lampropholis delicata
The delicate skink, scientifically known as Lampropholis delicata, is a small lizard native to Eastern Australia, recognized for its smooth scales and diurnal nature. It exhibits notable color dimorphism, with variations in stripe patterns between males and females, though the stripe is generally less pronounced in males. This species has successfully established itself as an invasive population in New Zealand and Hawaii, where it is commonly found thriving in suburban gardens and various moist habitats.
Habitat and Distribution
Originally from Eastern Australia, Lampropholis delicata inhabits a range of environments including woodlands, heaths, sclerophyll forests, and rainforests. Its adaptability has allowed it to colonize new territories, becoming a common sight in gardens in New Zealand and Hawaii. On the Hawaiian Islands, it has been observed at high altitudes, demonstrating a preference for wetter, cooler environments.
Physical Characteristics and Behavior
Adult delicate skinks possess a moderate body with a slender tail. Their coloration typically ranges from greyish-brown to rich brown, often flecked with darker and paler markings, and frequently featuring a narrow yellowish-brown stripe. The species is diurnal, with activity levels peaking during the warmer months. A key behavioral trait is caudal autotomy, the ability to shed its tail as a defense mechanism against predators, followed by spinal cord and tail regeneration.
Diet and Reproduction
As an opportunistic carnivore, Lampropholis delicata's diet consists of a variety of invertebrates such as spiders, bees, larvae, termites, and snails. They employ active foraging and 'sit-and-wait' strategies to capture prey. Reproduction occurs seasonally, with mating typically in late summer. Females lay one clutch per year, usually containing 2 to 4 eggs, although communal nests with many more eggs are not uncommon. Clutch size is positively correlated with the female's body size.

Frequently Asked Questions
What are the common names for Lampropholis delicata?
Lampropholis delicata is known by several common names, including the delicate skink, dark-flecked garden sun skink, garden skink, delicate garden skink, rainbow skink, plague skink, and metallic skink.
Where is Lampropholis delicata found?
This species is native to Eastern Australia. It has also been accidentally introduced and is now invasive in New Zealand and Hawaii, where it is frequently found in gardens.
What does Lampropholis delicata eat?
The delicate skink is an opportunistic feeder with a diet that includes a wide range of prey. Commonly consumed items include spiders, bees, larvae, termites, insects, snails, and crustaceans.
How does Lampropholis delicata defend itself?
A notable defense mechanism of Lampropholis delicata is caudal autotomy, the ability to intentionally shed its tail. This serves to distract predators and allow the lizard to escape. The species is also capable of regenerating its spinal cord and tail.
What are the reproductive habits of Lampropholis delicata?
Mating typically occurs in the late summer. Females usually lay one clutch per year, consisting of 2 to 4 eggs, though clutch sizes can range from 1 to 7. Communal egg nests containing many eggs are also common.
Does Lampropholis delicata have sexual dimorphism?
Yes, sexual dimorphism is present in Lampropholis delicata. Males tend to have broader, longer heads, while females generally have larger abdomens and body sizes. Coloration also differs, with stripe expression often reduced in males.
What kind of habitat does Lampropholis delicata prefer?
The delicate skink inhabits a variety of moist environments such as woodland, heaths, sclerophyll forests, and rainforests. They also adapt well to suburban gardens. They prefer open microhabitats with structured leaf litter, which aids in thermoregulation and foraging.
Is Lampropholis delicata considered a pest species?
In New Zealand, where it is known as the 'plague skink', it is considered invasive because it competes with native lizards for food and habitat. High populations can also indirectly impact native species by increasing the predator population that preys on lizards.
