Lined Day Gecko: Care, Diet, Behavior, As Pet, Handling

The Lined Day Gecko (Phelsuma lineata) is a diurnal, omnivorous, and arboreal species of gecko native to Madagascar. They are also found in the Reunion Island, where they have been introduced. These geckos are primarily active during the day and inhabit tropical forests, spending most of their lives off the ground.

They have striking colors and patterns and are popular in the pet trade due to their attractive appearance and fascinating behaviors. There are three recognized subspecies of the Lined Day Gecko.

Physical Description

Lined day geckos typically grow to a length of 4-6 inches (10-15 cm). The smallest subspecies, Phelsuma lineata bombetokensis, measures 10-11 cm in total length. Lined day geckos are vibrant in color, boasting a bright green body that helps them blend in with their tropical surroundings.

Distinctive features and patterns

Lined day geckos are named for the distinct lines that run along the length of their body. These lines are usually a combination of red, blue, and white hues, creating an attractive contrast against their vivid green backdrop.

Their heads may also exhibit red spots or patterns, adding to their unique appearance. Their eyes are large and round, with vertical pupils, which is a common feature among geckos.

As an arboreal species, lined day geckos have specialized toe pads with adhesive properties, allowing them to effortlessly climb and navigate their environment.

Anatomy and Physiology

This stored fat can be utilized during times of food scarcity. Moreover, like many other geckos, Lined Day Geckos have the ability to detach their tail when threatened, a phenomenon known as autotomy. This is a defensive strategy to distract predators, allowing the gecko to escape.

The detached tail will wriggle and twitch for a while, drawing the predator’s attention, while the gecko makes its escape. Over time, the gecko will regenerate a new tail.

Lifespan in the Wild Versus in Captivity

The exact lifespan of Lined Day Geckos in the wild is not well documented. However, like other geckos, they face various challenges in their natural habitat, such as predation, competition for resources, and environmental changes. These factors can impact their overall lifespan and make it difficult to determine an accurate average life expectancy.

Lifespan in Captivity

In captivity, Lined Day Geckos generally have a longer lifespan compared to their wild counterparts. This is primarily due to the controlled environment, which provides a consistent supply of food, stable living conditions, and protection from predators.

With proper care, Lined Day Geckos can live anywhere from 8-10 years or more in captivity. However, it is essential to provide them with appropriate housing, a balanced diet, and proper temperature and humidity levels to ensure their health and longevity.

Behavior and Social Structure

Diurnal nature and occasional nocturnal activity

Lined Day Geckos are primarily diurnal, meaning they are active during the day. They spend their days hunting for food, basking in the sun, and maintaining their territory. However, they can sometimes be active at night, especially when attracted to house lamps that draw insects, which are their primary food source.

Their activity patterns are influenced by factors such as light, temperature, and availability of food.

Social Structure and Interaction

Lined Day Geckos are generally solitary creatures, with each individual maintaining its own territory. They can be territorial and may display aggressive behavior towards other geckos if their space is invaded.

Males, in particular, may engage in aggressive encounters with other males to establish dominance and secure access to resources and potential mates.

During the breeding season, males will seek out females and engage in courtship displays to attract a mate. Once mating has occurred, the female will lay her eggs, and both the male and female will return to their separate territories.

Diet in the Wild and in Captivity

Lined Day Geckos are omnivorous creatures and their diet primarily consists of insects and other invertebrates. They are attracted to house lamps that draw insects, making these a significant part of their diet. They are also known to consume nectar and fruit, indicating a varied diet.
