The Standing's day gecko (Phelsuma standingi) is an arboreal and diurnal species of gecko, native to southwest Madagascar. It is among the largest living species of day geckos. Standing's day gecko feeds on insects and nectar.

Etymology

Its generic name is a Latinized version of the last name of Dutch physician Murk van Phelsum.[citation needed] Its specific name is in honor of another physician, Doctor Herbert F. Standing of Antananarivo, Madagascar. [1]

Description

This lizard is among the largest extant species of day geckos. It can reach a maximum length of 28 centimetres (11 in). The body colour can be quite variable, depending on light intensity. It can be brownish grey or bright green or turquoise with grey to blue reticulated markings on its body and head. The head and tail are often turquoise. Hatchlings have a yellowish green head and typical light bands and bars on their backs.

It is a sexually dimorphic species. In the males cloacal area has very pronounced preanal pores than the femaleS and a bulge in the area of hemipenis. In many females two endolymphatic chalk sacs, located on the sides of their necks, are well-developed, while in males usually they are just barely visible. These sacs store calcium, which is needed for the formation of the egg shells..

Distribution and habitat

Phelsuma standingi is restricted to the arid southwest of Madagascar, specifically the region around Andranolaho and Sakaraha. This area has a unique thorn forest vegetation. The daytime temperature never drops under 20 °C (68 °F) and between January and December, the temperature can be as high as 40 °C (104 °F) in the shade. In July and August, the night temperature can drop to 13 °C (55 °F).

Diet

Standing's day gecko feeds on various insects, invertebrates, and even smaller lizards. It is omnivorous however, supplementing its prey with soft, sweet fruit, pollen and nectar.

Behaviour

This strictly arboreal species lives in pairs on trees. where these geckos spend a lot of time to bask in the sun on the highest and well exposed branches. The males are very territorial and will fight when in the presence of other males. Also females have this character with other females, behaviour rather rare in geckos.

Reproduction

At a temperature of 28 °C (82 °F), the young will hatch after approximately 60–70 days. The juveniles measure 80 mm and reach sexual maturity after one year.

Care and maintenance in captivity

These animals should be housed in pairs and need a large, planted terrarium. The daytime temperature should be around 30 °C (86 °F). A spot lamp should provide the animals with a basking spot and a local temperature of 35 °C (95 °F). At night, the temperature should be dropped to 22 °C (72 °F). In captivity, these animals can be fed with crickets, wax moth larvae, mealworms and houseflies.
