Day Gecko: Origin, Characteristics, Behavior, Diet, Care

Day Geckos, scientifically known as members of the Phelsuma genus, is a vibrant and fascinating group of lizards that have captured the attention of both scientists and pet enthusiasts around the world.

Origin of Day Gecko

Day Geckos, scientifically known as the Phelsuma genus, are originally from warm climates and are native to various parts of the world. The highest species diversity is found in Madagascar and surrounding islands, but they also inhabit other areas, such as the Seychelles, Mauritius, and Comoros islands, and some species can even be found in parts of East Africa and India.

The diverse habitats of these geckos range from humid rainforests to dry deciduous forests and domestic gardens. The genus Phelsuma includes more than 70 species and subspecies, each with their unique distribution and habitat preferences.

Why is it called a Day Gecko?

The term “day gecko” is derived from the diurnal nature of these creatures. Unlike many other geckos that are nocturnal, day geckos are active during the day. The genus name “Phelsuma” also reflects this characteristic, with “Phelsuma” being derived from Greek words meaning “dappled light,” a reference to the bright, sunlit environments these geckos typically inhabit.

What makes Day Geckos stand out, aside from their scientific significance, is their stunning and colorful appearance. Their vibrant hues range from brilliant greens to blues, often adorned with speckles, stripes, or other patterns in contrasting colors. This colorful display is not just for show; it plays a critical role in their communication and mating rituals.

Their diurnal nature allows them to have a different niche from their nocturnal relatives, reducing competition for resources and offering a different set of predators and prey.

In the forthcoming sections, we’ll delve deeper into the captivating world of Day Geckos, exploring their physical characteristics, behavioral traits, dietary preferences, and their potential as pets.

Physical Characteristics

Day Geckos are renowned for their vibrant and variable coloration, which ranges from radiant greens and blues to more subtle shades of yellow, orange, or even pink. These colors are often accentuated by patterns such as spots, stripes, or bars, which can vary greatly between different species and even individuals within the same species.

Day Gecko Size

When it comes to size, Day Geckos display considerable variation. Some species, like the dwarf day geckos, only reach lengths of about 3 inches. On the other hand, the larger species, like the Giant Day Gecko (Phelsuma grandis), can grow up to 12 inches long from head to tail. Regardless of their size, all Day Geckos shares a slender, streamlined body shape that’s well-adapted to their arboreal lifestyle.

One of the most remarkable features of Day Geckos – shared among all geckos – is their feet. Geckos have evolved an extraordinary adaptation for climbing: their toes are covered with tiny scales known as setae, which allow them to adhere to even the smoothest surfaces.

Each of these setae branches out into hundreds of tinier structures called spatulae, which can establish van der Waals forces with the surface the gecko is climbing. This essentially allows the gecko to “stick” to the surface without the need for any liquids or surface tension.

This amazing feature enables Day Geckos to effortlessly scale vertical walls and even traverse ceilings, much to the delight and amazement of onlookers.

Behavior and Lifestyle

Day Geckos stand out from many other gecko species due to their diurnal (daytime) activity pattern. While most geckos are nocturnal, Day Geckos buck this trend and are most active during daylight hours. This is when they venture out to forage, socialize, and engage in other behaviors. The bright daylight accentuates their vibrant colors, making them a delight to observe for reptile enthusiasts and casual observers alike.

These geckos are exceptional climbers, a skill facilitated by their specialized adhesive feet, as discussed in the previous section. They are arboreal, meaning they spend most of their time in trees or other high places, which is also where they hunt for food and seek out mates.

interaction with humans

Their natural habitats often include rainforests, where they’re found in the canopy, but they’re also comfortable in human-altered environments and can often be found in gardens or on the walls of buildings.

Despite their vibrant beauty and fascinating behaviors, Day Geckos are known to be somewhat delicate creatures. Their skin is quite thin and can be easily damaged, so they should be handled with extreme care, if at all. In fact, many recommend not handling these geckos except when absolutely necessary, as the stress can be harmful to them.

When they feel threatened or excessively stressed, Day Geckos may resort to a common defensive mechanism known as tail autotomy, or tail dropping. This involves the gecko voluntarily shedding its tail to distract predators, giving it a chance to escape. While the tail does regenerate over time, it’s a process that can put significant stress on the gecko’s resources.

Day Gecko Lifespan

The lifespan of a Day Gecko varies based on species and the conditions in which they live. In the wild, they may live for several years, but in captivity under optimal conditions, they can live up to 10-20 years. Their interaction with humans largely depends on their individual personalities and the amount of gentle, gradual socialization they’ve received.

Some Day Geckos may tolerate gentle handling and can be quite curious, while others may be more skittish or defensive. It’s always important to respect their boundaries and observe their behaviors closely for any signs of stress or discomfort.

Day Gecko Diet

Day Geckos are omnivorous creatures, meaning they consume a diverse diet comprising both plant and animal matter. However, the primary component of their diet consists of various insects, making them largely insectivorous.

Day Gecko Diet in Wild

In their natural habitat, Day Geckos feed on a wide array of insects, including roaches, silkworms, waxworms, and butter worms, among others. The insects provide them with the necessary protein and other nutrients essential for their growth, health, and vitality. They are skilled hunters, using their keen eyesight and agile bodies to catch their prey.

Aside from insects, Day Geckos also consume fruits, contributing to their omnivorous nature. They particularly favor tropical fruits such as papaya and mango, which offer a range of beneficial nutrients. The sugar content of these fruits provides them with energy, while the other nutrients help round out their diet.

Day Gecko Diet in Captivity

In captivity, the diet of Day Geckos should mimic their natural dietary habits as closely as possible. Owners can feed them a variety of insects such as crickets, mealworms, and roaches. It’s recommended to “gut load” these insects before feeding, which means providing the insects with nutritious food that will, in turn, be passed on to the gecko.

Furthermore, it’s common practice to dust the insects with a calcium or vitamin D3 supplement to ensure the gecko is receiving these crucial nutrients.

Fruits can be offered in the form of fresh, ripe pieces or as a commercial fruit puree or nectar. Some gecko owners opt for a commercial diet specifically designed for Day Geckos, which can be a convenient and balanced option. However, fresh food should still be included regularly to provide variety and enrichment.

Remember, all geckos have unique dietary preferences, so it’s essential to observe your gecko and adjust their diet accordingly. It’s also crucial to offer food in appropriate sizes to avoid choking hazards. For example, the size of the insects offered should generally not exceed the space between the gecko’s eyes.

Suitability as Pets

Day Geckos, with their vibrant colors and active daytime habits, can make for interesting and visually appealing pets. They are relatively easy to care for, making them suitable for both beginner and experienced reptile enthusiasts.

However, their skin is quite delicate, and handling them can cause stress and potential damage to their skin. Hence, they are better suited for owners who are content with observing their pets rather than handling them regularly.

The cost of purchasing a Day Gecko can vary greatly, typically ranging from $50 to $250 depending on the specific species, age, and breeder. It’s recommended to obtain one from a reputable reptile breeder to ensure they are less likely to carry diseases.

Day Gecko Temperature

Maintaining proper temperature and humidity levels in their enclosures is crucial for the health of Day Geckos. As cold-blooded creatures, they need to regulate their body temperature. A thermal gradient in the cage allows the lizard to move around and find its comfortable spot.

Daytime temperatures should be between 80 and 85 degrees Fahrenheit, and nighttime temperatures should be between 72 and 77 degrees. They also need relatively high humidity in their enclosures, ranging anywhere from 60 percent to 80 percent, depending on the species.

A hygrometer or humidity gauge can be used to accurately detect the humidity level. Regular misting of the tank, the use of live plants, and a proper substrate will help maintain the right level of moisture.

Enclosure Size Recommendations

The size of the terrarium for Day Geckos will depend on the species, but in general, a glass terrarium measuring 24 inches high by 12 inches wide and long is usually sufficient for one specimen.

They are climbing animals, so vertical space is as important as horizontal space. The enclosure should be securely closed as Day Geckos are known to be great escape artists.

Humidity and Water

Maintain a humidity level of 60 to 80 percent in the enclosure. Use a hygrometer or humidity gauge to accurately measure it. Regular misting of the tank, proper substrate, and live plants can help maintain this moisture level. A shallow dish of fresh water should always be available.

Line the bottom of the cage with a substrate that helps maintain a humid environment. Ideal substrates include peat moss, organic potting soil (no vermiculite), or orchid bark.

Provide plenty of climbing opportunities with branches, vines, and live or artificial plants. Ensure any decor is secure and won’t topple over. A hiding spot, such as a hollow log or cork bark, will also help your gecko feel secure.

Do day geckos like to be held?

Day Geckos are generally not ideal for handling. They are known for their delicate skin, which can be easily damaged if handled roughly or frequently. Handling can also stress them out, which can lead to health problems or defensive behaviors like dropping their tail.

While their tails can regenerate, it’s best to avoid causing them unnecessary stress or harm. However, if you need to handle your Day Gecko—for example, for tank cleaning or veterinary care—it’s important to do so gently and infrequently. Make sure your hands are clean and free of any lotions or chemicals that could harm the gecko.

Scoop the gecko up gently rather than grabbing it, and let it walk from hand to hand rather than restraining it. Remember, Day Geckos can become more accustomed to human presence over time, particularly if they are captive-bred.

They may become more tolerant of occasional, gentle handling with patience and consistent, positive interactions. Always observe your gecko’s behavior and stress levels during these interactions and give them plenty of time to rest and recuperate afterward.

Day Geckos Care


Day Geckos primarily feed on insects like roaches, silkworms, waxworms, and butter worms. In captivity, most geckos will eat three to five insects twice weekly. They can also consume tropical fruits such as papaya and mango or even fruit baby food.

Commercial nectar substitutes can be used in conjunction with the fruit baby food and should be offered once a week. Juveniles are typically fed daily while adults are fed every other day.

Habitat Setup

The habitat setup for a Day Gecko should be a secure glass enclosure that can maintain high humidity and proper temperature gradients. The substrate, or bedding, should help maintain a humid environment. Ideal substrates include peat moss, organic potting soil (no vermiculite), or orchid bark. Live plants can be added for aesthetics and to assist in maintaining humidity.

Handling Precautions

Day Geckos are fragile and are known to drop their tails when stressed. Therefore, handling should be minimal to prevent stress and potential injury.

Importance of UV Light Exposure

Exposure to ultraviolet light is crucial for Day Geckos. Fluorescent, full-spectrum UVB-emitting reptile bulbs should be used to provide 10 to 12 hours of UV light. The bulbs should be changed every six months, as the invisible UVB rays stop emitting after this period.

Health Check-ups and Potential Issues

Regular veterinary check-ups are important for Day Geckos, as they can help detect and treat potential health issues early. Some common health problems include skin disorders (often due to improper shedding), parasitic infections causing weight loss or digestive issues, and metabolic bone disease.

Always ensure the gecko has access to adequate UVB light and calcium supplements to prevent metabolic bone disease. Additionally, maintaining clean and proper enclosure conditions can help prevent many of these health issues.


How do Day Geckos communicate with each other?

Day Geckos, like many other reptile species, communicate primarily through visual signals. They use body movements, color changes, and other visual cues to communicate various messages, such as territorial claims, mating readiness, or aggression.

How does Day Geckos sleep if they are diurnal?

Day Geckos, being diurnal creatures, are active during the day and sleep at night. They don’t have eyelids, so instead of closing their eyes, they have a transparent membrane which they clean with their tongues. When sleeping, they find a secure spot in their environment, usually high up in the trees or foliage, and remain still until dawn.

What types of predators do Day Geckos have in the wild?

In the wild, Day Geckos have a variety of predators, including larger reptiles, birds, and mammals. Their bright colors can make them an attractive target, but they rely on their agility, speed, and ability to climb to escape from danger.

Can Day Geckos cohabit with other species in a terrarium?

It’s generally not recommended to house Day Geckos with other species, as this can lead to stress, territorial disputes, and even predation. It’s best to provide each Day Gecko with its own dedicated enclosure, or if housing multiple Day Geckos together, ensure they are of the same species and have plenty of space to avoid territorial conflicts.

What is the average clutch size for Day Geckos?

The average clutch size for Day Geckos can vary depending on the specific species, but generally, females lay one to two eggs per clutch. These eggs are usually laid on a surface in a secure, hidden location within the gecko’s environment.

How does Day Geckos regulate their body temperature?

As cold-blooded creatures, Day Geckos regulate their body temperature through their behavior. This is known as behavioral thermoregulation. They do this by moving to warmer or cooler areas in their environment as needed. For instance, they may bask in the sun to warm up, move into the shade or burrow into cooler soil to cool down.

Can Day Geckos change color like chameleons?

While Day Geckos can’t change their color as dramatically or rapidly as chameleons, some species have been known to alter their coloration slightly based on their mood, stress levels, or in response to temperature changes. However, their ability to change color is limited compared to that of a chameleon.


In conclusion, Day Geckos, belonging to the Phelsuma genus, are a fascinating group of colorful, diurnal lizards known for their vibrant appearance, unique adhesive feet, and climbing abilities. Their insectivorous diet, along with some fruit consumption, makes them an interesting choice for reptile enthusiasts.

However, they require specific care and attention to ensure a proper environment, including temperature, humidity, and lighting.

While Day Geckos can be kept as pets, it’s important to remember that they are fragile creatures, and handling should be limited to avoid injury or stress. Providing a suitable enclosure with adequate space and proper environmental conditions is crucial for their well-being.

By conducting thorough research and understanding their needs, reptile enthusiasts can enjoy the beauty and unique behaviors of these captivating lizards while ensuring their health and happiness.
