This lizard belongs to the middle sized day geckos. It can reach a total length of about 15 cm. There always is a dorso-lateral strip present, which may be broken. A red stripe extends from the nostril to the shoulder. The male body colour is light green or bluish green. The back of males has a bright blue colour and is covered with dark red spots and dashes. The males have a deep blue tail. Females lack the brilliant blue colour of the males. They have a bright green back and rust-coloured spots.


This species inhabits the island Mauritius where it is widely distributed. P. cepediana may also have been introduced to Madagascar where it has been reported a few times, amongst others in the region of Iviloina. These observations have not been confirmed though.


P. cepediana is mainly found on bushes and trees such as coconut palms, traveler's palms, banana trees and papayas. They also inhabit gardens and houses in suburban areas. These geckos prefer a moist and warm climate. McKeown (1993) mentions that the original vegetation of Mauritius has been largely replaced with agricultural crops where these day geckos cannot live.


These day geckos feed on various insects and other invertebrates. They also like to lick soft, sweet fruit, pollen and nectar.


This Phelsuma spec. can be quite aggressive both toward their own and to other Phelsuma species. In captivity, where the females cannot escape, the males can also sometimes seriously wound a female. In this case the male and female must be separated.


The females lay their eggs in a protected location. These Phelsumas glue their eggs. At a temperature of 28°C, the young will hatch after approximately 40–45 days. The juveniles measure 40 mm.

Care and maintenance in captivity

These animals should be housed in pairs and need a large, well planted terrarium. It is important to provide the terrarium with sufficient air flow. The temperature should be between 28 and 30°C. The humidity should be maintained between 75 and 100. In captivity, these animals can be fed with crickets, wax moth, fruits flies, mealworms and houseflies.
