Phelsuma is a large genus of geckos in the family Gekkonidae. Species in the genus Phelsuma are commonly referred to as day geckos.

Some day geckos are seriously endangered and some are common, but all Phelsuma species are CITES Appendix II listed. Little is known about trade in day geckos,[1] but the IUCN considers it a threat to some species. Some species are captive-bred.[2]

The genus itself is thought to have originated anywhere between the Late Cretaceous to the mid-Eocene (43 to 75 mya), as that is when its lineage is known to have diverged from the one containing the Namaqua day gecko (Rhoptropella), although it is unknown how closely related both genera are. The crown group containing all recent species is thought to have originated in the early Oligocene, about 30 million years ago, with the most basal of them being the isolated Andaman day gecko (P. andamanensis), which diverged from all other species shortly after the crown group originated.[3] Most of the other divergence among species in areas of the Western Indian Ocean such as the Seychelles is thought to have occurred in the Neogene.[4]

In contrast to most other gecko species, day geckos of the genus Phelsuma are active mainly during the day. Other diurnal geckos include species of the genera Lygodactylus and Gonatodes. Like most other geckos, day geckos lack eyelids, instead having rounded pupils and a clear, fixed plate covering their eyes which they clean with their tongues. Many species have bright green, red, and blue colors which make them popular terrarium or vivarium pets. These brilliant colors play a role in intraspecies recognition and also serve as camouflage.

The total length (including tail) of the different Phelsuma species varies between about 6.5 and 30 centimetres (2.6 and 11.8 in), but the extinct Rodrigues giant day gecko was even larger. Day geckos have toe pads consisting of tiny lamellae which allow them to walk on plain vertical and inverted surfaces like bamboo or glass. The inner toe on each foot is vestigial. Males have well-developed femoral pores on the undersurface of their rear limbs. These pores are less developed or absent in females. Females often have well-developed endolymphatic chalk sacs on the sides of their necks. These sacs store calcium, which is needed for egg production. Those eggs can often be seen through the ventral surface of the female's body shortly before they are laid. The hatchlings reach sexual maturity between six and 12 months old. Smaller species may live up to 10 years, whereas the larger species have been reported to live more than 20 years in captivity.
Distribution and habitat

Day geckos inhabit the islands of the south-west part of the Indian Ocean. The exceptions are Phelsuma andamanense, which is endemic to the Andaman Islands in the Bay of Bengal, and Phelsuma dubia, which is also found on the East Coast of mainland Africa, although it possibly was introduced there. Most Phelsumas species are found in Mauritius and Madagascar. Some species are found on neighboring island groups, including the Mascarenes, Seychelles, and Comoros. Due to human introduction, they are also often found on some of the Hawaiian Islands, including the Big Island, Maui and Kauai, and the state of Florida, where they were introduced as a form of pest control. The different Phelsuma species can be found from sea level up to 2,300 meters. Most day geckos are arboreal. They inhabit, amongst others, coconut palms and banana trees, but can also be found near human settlements, in gardens, on fences, houses, and huts. An exception, Phelsuma barbouri, is a terrestrial species.

Day geckos feed on various insects and other invertebrates in the wild. They also eat nectar, pollen, and occasionally soft, ripe and sweet fruits such as bananas.

In captivity, such a diet is simulated. Insects which may be used include: (wingless) fruit flies, various flies, wax moths, crickets, small super worms, small butter worms and mealworms. Fruit, which is required a few times a week, may be small pieces of papaya, banana, or other sweet fruit and also commercial gecko nectars.

In 2008 a BBC film crew took footage of a day gecko successfully begging a planthopper for honeydew.[5]

The genus Phelsuma was first described in 1825 by the British zoologist John Edward Gray, who named it after the Dutch physician Murk van Phelsum.[6] The genus consists of about 70 known species and subspecies.

Two Phelsuma species (Phelsuma gigas and Phelsuma edwardnewtoni), both of which were endemic to the Mascarene island of Rodrigues, are now considered to be extinct, probably due to the destruction of their environments by human settlers and their domestic animals. Many day gecko species are endangered today for similar reasons: an increasing percentage of their natural habitat, especially tropical forest, is being destroyed by human activity.
