In the exciting world of herpetology, crested geckos, also known as “Eyelash Geckos,” have captivated the hearts of many. Native to New Caledonia, these charismatic creatures are popular in the pet trade due to their manageable size, striking appearance, and unique behavior. One aspect of their behavior, in particular, has piqued the interest of gecko enthusiasts: their sleep and activity patterns. This blog post seeks to answer the frequently asked question, “Are crested geckos nocturnal?” Spoiler alert – they are!

Understanding Crested Geckos


One fascinating characteristic of crested geckos is their ability to regenerate their tails. In times of danger or stress, they can detach their tails as a defense mechanism, allowing them to escape potential predators. The detached tail will then regrow over time, albeit not exactly identical to the original. This regenerative ability serves as an additional unique feature of these geckos.

Their arboreal lifestyle is facilitated by specialized toe pads on their feet. These toe pads contain tiny hair-like structures called setae, which enable the geckos to grip surfaces with remarkable ease. This adaptation allows them to navigate vertical surfaces, including tree trunks and leaves, effortlessly.

Crested geckos are primarily insectivorous, with a diet consisting of a variety of insects, fruit, and nectar. In captivity, they are commonly fed a diet of commercially available powdered diets, which provide the necessary nutrients for their well-being. Offering a balanced and varied diet is essential for their health and longevity.

While crested geckos are known to be primarily nocturnal, it is important to note that they do display some activity during the day. These daytime activities often occur during dawn and dusk, when the geckos may engage in exploring their surroundings, grooming, or hunting for food. However, their true peak activity occurs during the night, when they are most active and alert.

To fully understand the behavior of crested geckos, it is crucial to consider their natural environment. The rainforests of New Caledonia are characterized by a significant temperature drop and decreased light levels during the night. These environmental cues play a significant role in triggering the geckos’ nocturnal behavior, as they are adapted to thrive in low-light conditions.

In conclusion, crested geckos are captivating creatures with unique characteristics that make them well-suited for their arboreal lifestyle. While they may exhibit some activity during the day, they are primarily nocturnal, displaying heightened activity, feeding, and hunting behaviors during the night. By understanding their natural habits and providing suitable care that respects their nocturnal nature, we can ensure that crested geckos thrive in captivity and continue to enchant reptile enthusiasts around the world.

Are Crested Geckos Nocturnal?


Now, to answer the question at hand. Yes, crested geckos are indeed nocturnal creatures. This means they are most active during the night and spend the majority of the daylight hours sleeping or resting. This nocturnal behavior is an evolutionary adaptation to avoid predators and to hunt for food when the temperatures are more favorable, as New Caledonia, their natural habitat, can be quite warm during the day. So, if you own a crested gecko, don’t be surprised if you notice them springing to life just when you’re getting ready for bed!

The Impact of Nocturnal Behavior on Crested Gecko Care


Understanding the crested gecko’s nocturnal behavior significantly impacts how they should be cared for as pets. For starters, their enclosure needs to accommodate their sleeping habits. Providing hiding places where they can sleep undisturbed during the day is vital. Moreover, since they are most active at night, their feeding schedule should coincide with their activity. Feeding them in the evening ensures they are active and ready to eat.

Furthermore, lighting for crested geckos should mimic their natural environment. UVB lighting is beneficial but not mandatory. They do not require intense light during the day, and too much light can disrupt their sleep and stress them.

Nocturnal vs. Diurnal Geckos: How Do They Compare?

Diurnal geckos, like the day gecko, have evolved to be active during the day, taking advantage of the abundant sunlight and warmer temperatures. Their activity levels are at their peak during daylight hours, when they engage in sunbathing, foraging for food, and interacting with their environment. Their eyesight is typically well-adapted to detect movement and color during daylight, allowing them to navigate their surroundings and locate prey.

In contrast, nocturnal geckos, such as the crested gecko, have adapted to thrive in low-light conditions and are most active during the night. Their senses, particularly their vision, have evolved to excel in dim lighting. Nocturnal geckos often possess large pupils that allow them to gather as much light as possible, enhancing their ability to see in the dark. Additionally, their retinas may contain specialized cells that are more sensitive to low levels of light, further aiding their nighttime vision.

The difference in activity patterns between nocturnal and diurnal geckos also impacts their dietary needs. Diurnal geckos typically feed on live insects, such as crickets and mealworms, as these food sources are abundant during the day. They may also consume nectar or fruit in their natural habitats. On the other hand, nocturnal geckos rely on a diet primarily composed of insects and other small invertebrates that are active during the night. These geckos have adapted to locate and capture prey in the darkness, using their specialized vision and other senses.

The care requirements for nocturnal and diurnal geckos can also differ. Diurnal geckos require access to full-spectrum lighting that mimics natural sunlight, providing them with the necessary UVB radiation for vitamin D synthesis. They also benefit from a daytime temperature gradient that allows them to regulate their body temperature through basking. Nocturnal geckos, on the other hand, may not require as much UVB lighting, as they are adapted to lower light conditions. However, providing a dim night light or moonlight simulation can help create a more natural environment for them.

Crested geckos, with their nocturnal nature and unique characteristics, have become a popular choice for reptile enthusiasts interested in observing and caring for a gecko that exhibits fascinating nighttime behaviors. Their captivating appearance, gentle demeanor, and low maintenance requirements make them ideal pets for those who appreciate the mysterious allure of nocturnal creatures.


In conclusion, yes, crested geckos are nocturnal. This behavioral trait plays a significant role in how they should be cared for, affecting everything from feeding times to lighting in their enclosures. Whether you’re a potential crested gecko owner or an experienced one, understanding your gecko’s nocturnal nature is key to ensuring they lead a healthy and fulfilling life. Happy gecko-keeping!
