The Blue-Tailed Day Gecko is a mid-sized gecko that can reach a total length, including the tail, of approximately 3.75 to 5.5 inches (or 9.5 to 14 cm). Female Blue-Tailed Day Geckos are usually smaller than males.
The color of this species is generally light green or bluish-green, with males typically displaying more vivid colors than females.
Distinctive features and patterns
One of the most noteworthy features of the Blue-Tailed Day Gecko is its ability to change colors and patterns ontogenetically, which means throughout its development. The coloration can vary depending on factors such as the gecko’s activity levels.
This color-changing ability allows the gecko to adapt to different environments and situations, providing it with a unique advantage in its natural habitat.
The Blue-Tailed Day Gecko possesses numerous adaptations that allow it to thrive in its environment. Its toes are equipped with specialized scales that enable it to cling to and climb smooth surfaces, even upside down. This adaptation is crucial for its arboreal lifestyle, allowing it to navigate swiftly among trees and bushes.
Their large, round eyes are well-suited for their diurnal nature, allowing them to spot predators, prey, and potential mates in the bright daylight. Additionally, their eyes are equipped with a fixed lens and a mobile retina, allowing them to focus and see clearly across different distances.
The characteristic blue tail of this gecko is another significant aspect of its physiology. In many gecko species, the tail serves as a defense mechanism, being able to break off when grabbed by a predator.
While it is not specified in the provided resources whether the Blue-Tailed Day Gecko possesses this ability, it is a common trait among many gecko species. The bright blue color of the tail may also serve to distract or confuse predators.
Behavior and Social Structure
Diurnal Nature and Activity Patterns
The Blue-Tailed Day Gecko is a diurnal species, which means it is most active during the day. Its daily activity consists of foraging for food, basking, and interacting with other geckos. The diurnal nature of these geckos means they have different patterns of behavior compared to many other gecko species that are nocturnal.
The Blue-Tailed Day Gecko’s ability to change its color and pattern ontogenetically helps it adapt to varying daylight conditions, offering it a unique advantage in its environment.
Social Structure and Interaction
The social structure and interaction patterns of the Blue-Tailed Day Gecko are not explicitly detailed in the provided resources. However, like many gecko species, they are likely to have a certain degree of social interaction.
This can include territorial displays, mating behaviors, and possibly some form of communication through visual signals, as is common in many diurnal lizards.
The specifics of their social structure, such as whether they form groups or largely live solitary lives, would require further research for a detailed understanding. As part of their interaction with the environment, these geckos also play an important role as pollinators in their ecosystem.
Lifespan in the Wild Versus in Captivity
Lifespan in the Wild – The lifespan of Blue-Tailed Day Geckos in the wild can vary significantly based on various factors such as predation, availability of food resources, and environmental conditions.
Unfortunately, specific lifespan data for Blue-Tailed Day Geckos in the wild is not readily available. However, many species of day geckos live on average around 5 to 8 years in the wild.
Lifespan in Captivity – In captivity, where threats like predation and food scarcity are controlled, Blue-Tailed Day Geckos can potentially live longer. Again, specific lifespan data for this species in captivity is not provided in the resources, but many species of day geckos can live up to 10 years in captivity with proper care, and some have been known to live up to 20 years.
Factors such as diet, habitat conditions, and healthcare can significantly influence the lifespan of these geckos in captivity.
It’s worth noting that the lifespan of any animal, including the Blue-Tailed Day Gecko, can be maximized by ensuring that they have a well-balanced diet, a suitable habitat, regular health check-ups, and minimal stress. In a captive setting, it is the responsibility of the keeper to provide these conditions.
What if a gecko bites you?
If a gecko bites you, it’s usually more surprising than harmful. Their bites are not typically strong enough to break human skin, but they can cause a minor pinch-like feeling. However, here are the steps you should follow:
- Stay Calm: First and foremost, try not to panic or jerk your hand away, as this might injure the gecko.
- Gently Remove the Gecko: If the gecko doesn’t let go, try to gently remove it without causing harm. You can use a soft item, like a piece of cloth, to encourage it to release its grip.
- Clean the Area: Once the gecko has released its grip, clean the area thoroughly with warm water and soap to prevent infection. Apply an over-the-counter antibiotic ointment if you have it.
- Monitor for Infection: Even though it’s unlikely, keep an eye on the bite area for signs of infection, such as redness, swelling, or pus. If you notice any of these symptoms, seek medical attention.
- Address the Cause: Finally, try to figure out what might have triggered the gecko to bite. It might have been scared or stressed. Consider ways to reduce the stress for your pet in the future.
Remember, geckos are not typically aggressive animals and don’t often bite unless provoked or frightened. If you’re regularly handling your gecko, do so gently and be respectful of its behavior and reactions.
Diet in Captivity
Diet Composition: The Blue-Tailed Day Gecko is an omnivorous species, feeding on both insects and plant matter. In captivity, their diet should consist of a variety of small, soft-bodied insects, such as crickets, fruit flies, and mealworms.
They also enjoy sweet fruits, pollen, and nectar, which can be provided through fresh fruits or commercially available nectar substitutes.
Feeding Frequency: Adult Blue-Tailed Day Geckos should be fed 2-3 times a week, while juveniles require daily feeding due to their higher metabolic rate and growth needs. The amount of food offered should be adjusted according to the gecko’s age, size, and activity level.
Calcium and Vitamin Supplementation: In addition to a varied diet, these geckos require additional calcium and vitamin supplements to ensure optimal health. Calcium powder can be dusted on the insects before feeding. A multivitamin supplement should also be provided at least once a week.
Hydration: Blue-Tailed Day Geckos drink water droplets from leaves and the sides of their enclosure, mimicking their natural behavior in the wild.
Regular misting of the enclosure is necessary, not only to maintain humidity but also to provide drinking water for the gecko. A shallow water dish can also be provided, though they may not use it as frequently as the droplets.
Blue-Tailed Day Gecko Care
Ideal Habitat Conditions in Captivity
Enclosure: The Blue-Tailed Day Gecko is arboreal, meaning they spend most of their time in trees. Therefore, they require a vertical enclosure that mimics their natural habitat. A terrarium with dimensions of at least 12”L x 12”W x 18”H is recommended for a single gecko. It should have plenty of climbing structures like branches, vines, and plants for the gecko to explore.
Temperature: Maintaining an appropriate temperature gradient in the enclosure is vital for the gecko’s health. Daytime temperatures should range between 26-30 degrees Celsius (79-86 degrees Fahrenheit), with a slightly cooler range at night. It’s important to provide a heat source, like a heat lamp, to achieve these temperatures.
Humidity: Blue-Tailed Day Geckos thrive in humid conditions. The humidity level in the enclosure should be maintained around 70-80%. This can be achieved through regular misting of the enclosure. It’s also crucial to provide a shallow water dish for the gecko to drink from.
Lighting: These geckos need access to UVB light, which is essential for their ability to metabolize calcium and maintain healthy bones. A UVB light source should be incorporated into the enclosure, and the gecko should be able to come within 2-4 inches of the light source to gain maximum benefit.
Substrate: The substrate in the enclosure should be something that can retain humidity well, such as coconut fiber or moss. It’s important to keep the substrate clean to prevent the growth of harmful bacteria.
Suitable Diet in Captivity
In the wild, Blue-Tailed Day Geckos feed on insects, nectar, and pollen. In captivity, their diet should include a variety of insects such as crickets, mealworms, and fruit flies. Soft, sweet fruits can also be offered, and a commercially available nectar supplement can provide the nutrients they get from nectar in the wild.
It is essential to dust food items with a calcium and vitamin D3 supplement to ensure proper nutrition.
Health Concerns and Preventative Care
Proper care and maintenance of habitat conditions can prevent many health issues. However, geckos are susceptible to several health problems, including metabolic bone disease due to inadequate UVB or calcium intake, and respiratory infections from incorrect humidity levels.
Regular health checks, a balanced diet, and appropriate habitat conditions are key to preventing these issues. Always consult with a vet experienced in reptile care for specific health concerns.

How does the Blue-Tailed Day Gecko change its color and patterns?
Blue-Tailed Day Geckos have the ability to alter their coloration and patterns, an adaptation known as ontogenetic color change. This change can occur based on factors such as temperature, light, mood, and health status of the gecko.
The exact mechanism of this change involves specialized cells in the gecko’s skin called chromatophores, which contain pigments and reflect light in different ways to produce different colors and patterns.
What role does the Blue-Tailed Day Gecko play in pollination?
Blue-Tailed Day Geckos play a significant role in their native ecosystems as pollinators. They have a particular affinity for nectar, which they lick from flowers. When they do this, they inadvertently collect pollen on their bodies, which then gets transferred to other flowers as the gecko moves about.
This is particularly notable in the case of the critically endangered plant species Roussea simplex, which relies solely on the Blue-Tailed Day Gecko for pollination.
What should I do if my Blue-Tailed Day Gecko escapes from its enclosure?
Firstly, don’t panic. Escapees can usually be found relatively close to their enclosure. Turn off all noise in the house and listen for any rustling sounds. Geckos are more active at night, so this might be the best time to look for them. Look in warm, dark, and secure places – behind furniture, under rugs, inside shoes, etc.
If you still can’t find your gecko, place a small dish of water and some of their favorite food near the enclosure, as they may return for it.
What are some signs that my Blue-Tailed Day Gecko might be ill?
Geckos are good at hiding illness, so it’s important to be observant of any changes in their behavior or appearance. Signs of illness can include a loss of appetite, lethargy, changes in feces, weight loss, shedding problems, changes in the eyes (cloudiness, swelling), and unusual bumps or spots.
If you notice any of these signs, it’s a good idea to consult with a vet who specializes in reptiles.
Can Blue-Tailed Day Geckos cohabitate with other species?
While it might seem like a good idea to add variety to your gecko’s enclosure by introducing other species, it’s generally not recommended. Different species have different needs in terms of diet, temperature, humidity, and habitat, and these may not be compatible.
Additionally, some species may be aggressive towards each other, leading to stress or even injury. It’s best to keep your Blue-Tailed Day Gecko with others of its own species, and only then if the enclosure is large enough and there are enough resources to prevent competition.
How often should I clean my Blue-Tailed Day Gecko’s enclosure?
A thorough cleaning of the enclosure, including disinfecting surfaces and replacing substrate, should be done approximately once a month. However, spot cleaning should be done daily to remove feces, uneaten food, and any other waste.
Regular cleaning is important to prevent the build-up of bacteria and fungi that could potentially harm your gecko.
Why is my Blue-Tailed Day Gecko not eating?
Loss of appetite in geckos can be due to a variety of reasons. These include stress, illness, improper temperatures or humidity levels, or even a lack of variety in their diet. If your gecko has stopped eating, it’s important to try and determine the underlying cause.
If the gecko appears unwell or continues not to eat for more than a few days, a vet visit is recommended.
Can Blue-Tailed Day Geckos recognize their owners?
While geckos don’t recognize their owners in the same way a dog or cat might, they can become familiar with their keeper’s presence and voice over time. They can also associate their keeper with positive experiences such as feeding, which can make them more comfortable and less likely to feel threatened.
Blue-Tailed Day Geckos are fascinating creatures, offering a unique blend of vibrant coloration, engaging behavior, and ecological importance. As pets, they can be a source of joy and learning, although they also require a significant commitment in terms of their care.
Understanding their needs and behaviors is key to ensuring a healthy and happy life for these remarkable reptiles. With the right care, these geckos can be a rewarding pet for those interested in the diverse world of herpetology.
