The Madagascar day gecko is yet another specie that has been introduced into the wild in the state of Florida. These reptiles belong to the gecko family, the genus (classification of animals) Phelsuma, and the species madagascariensis, These cool green geckos reside on the island of Madagascar, and they usually live in rainforest trees. The Madagascar day gecko is one of the largest species of day geckos, and can grow to be just under 9 inches in length. They are a green-blue color with brown-brick red spots down their backs, and a similarly colored stripe from their nostrils to behind their eye. While these geckos are mostly found in the trees of the rainforest, deforestation has caused them to lose much of their usual habitat, and they have been known to dwell in villages and live inside the huts and banana trees on the eastern coast of Madagascar as a result. These brightly colored creatures eat insects and fruit (but only if it is soft!), and have been known to eat pollen and nectar as well.
Madagascar Day Geckos are very common in the pet trade, and they are easily kept and bred for sale in the United States. Usually housed alone, these lizards can be very territorial and even male-female pairs will occasionally fight. They thrive in 50-60% humidity and 80-90 degrees Fahrenheit, making them perfectly suited for Florida weather. Day geckos were first reported as being seen in Florida in the 1990s. There is one population in one county which has been reported as sustainable and breeding on their own, and have been sightings in three other counties where breeding has not been reported.
The most established population of day geckos is located in the Florida Keys. They are seen on white mangroves, buttonwood trees, buildings, and other man-made structures near mangrove estuaries. They were first reported outside of the Keys, in Broward county in 1999. These animals were confirmed as released or escaped pets, and the population in the Keys is a result of a single introductory event. Due to their popularity in the pet trade, and the suitability of Florida weather, a pet breeder released many adult individuals with the intention of having them breed and he harvests the hatchlings to be sold as pets.
This is another great example of how easy it is for nonnative animals to become established in areas where they do not belong. The geckos do not appear to have an adverse impacts on native Florida wildlife, however species such as the Argentine tegu and Burmese python were released and are wreaking havoc on native animals in Florida.
There are over 40 different species of day gecko, but the Madagascar day gecko is one of the most well known species. Below are photo of other day gecko species:
