Sexual dimorphism is present in L. delicata, in which males have broader, longer heads and females have larger abdomen and body sizes.

Female reproduction takes place in the spring season and more commonly in the late summer, ranging between the months of September and February.

Although the immediate survival benefits are evident, the subsequent lack of a tail hinders locomotion, interferes with habitat use and activity, and increases an individual's susceptibility to future encounters with predators.

Additionally, because lizards become less active after autotomy, they increase the amount of time spent in shelters or microhabitats, which may decrease their vulnerability to predators in the short term, but impacts their foraging ability, thermoregulatory mannerisms, and tail regeneration efficiency.

These lizards’ spinal cords consist primarily of ependymal cells that group around a tubular central canal containing cerebrospinal fluid.

As a result of topographic and dry habitat barriers, Lampropholis delicata have evolved to demonstrate a complex mosaic of non-overlapping, geographically oriented clades and subclades.

Since the accidental introduction of L. delicata into eastern Australian habitats, many biogeographic barriers and climatic oscillations have contributed to the evolutionary history of these lizards.

They reside over a vast array of moist habitats, including woodland and heaths, sclerophyll forests, and rainforests, while also making appearances in suburban gardens near the eastern coast.

Additionally, the phylogeographic breaks demonstrated by L. delicata along with many other lizard species is believed to be caused by cycles of marine inundation experienced by the area since the Miocene epoch.

An in depth analysis of L. delicata gut samples—taken from their foregut, hindgut, and stomach—reveals the wide variety of prey taxa and size classes incorporated into their diets.

These gut samples are taken from L. delicata that reside in the Mumbulla State Forest, a region with a vast history of fires and logging.

[10] L. delicata are characterized as general feeders, and their prey can be described as aerial and arboreal (i.e. bugs, beetles), slow-moving (i.e. larvae), concentrated (i.e. termites, ants), concealed (i.e. crickets, cockroaches), and active (i.e. spiders).

[11] With selecting a habitat, animals must consider the cost and benefit trade-offs of acquiring shelter and food while evading competitors and predators.

Thus deciding the degree of exposure or insulation, canopy or ground cover, structure of litter layer, or amount of grasses, forbs, rocks, and woody debris within the shelter remain prevalent considerations for lizard habitats.

For small lizards like L. delicata, the structure of the leaf litter layer influences thermoregulation, feeding, and refuge seeking, making it an influential factor in microhabitat selection.

Such open structure makes thermoregulation more effective, as lizard individuals can move into different positions within their habitat to avoid overheating or raise their temperature to more optimal levels.

Achieving optimum temperature levels influences their efficiency in avoiding predators and capturing prey, thus making open habitats conducive to many other behavioral characteristics.

[7] Although the biological mechanisms of reproductive cycles between male and female L. delicata lizards differ, they align seasonally such that mating can occur in the late summer.

[8] However the ultimate cause of this color dimorphism is not entirely conclusive for each sex but may be attributed geographical distribution, natural barriers, habitat preference, and sexual selection.

The species prefers an open substrate environment because the ground cover and loose leaf litter allows for thermoregulation, protection and optimal foraging conditions.

Called "metallic skink" in Hawaii where it was accidentally introduced in the early 1900s, it was misidentified as Lygosoma metallicum[6] and has since been reclassified as Lampropholis delicata.

It was noted as an unreported specimen taken on the Oahu island and identified as a Lipinia noctua at that time, then later reclassified as Lygosomoa metallicum (the metallic skink) because of its physical appearance.

[15] The three populations of L. delicata found on the main island, Oahu, and Kauai differ with respect to their average body length and in the numbers of eggs they produce.

It is theorized that Oahu females grow to a relatively smaller body size because of their higher population densities, thus creating competition amongst individuals for food and space availability.

Competition against other species might also be a possibility, and the inter and intraspecific competition experienced by Oahu females may also serve to explain the reduced egg production, as generally body size correlates to clutch size (smaller individuals with less internal body capacity lay fewer eggs than larger individuals).
