Orange-spotted day gecko

Mauritius Lowland Forest Day Gecko

The Mauritius lowland forest day gecko, scientifically known as Phelsuma guimbeaui, is a vibrant diurnal lizard native to the western coastal regions of Mauritius. It is also commonly referred to as Guimbeau's day gecko or the orange-spotted day gecko, with its specific name honoring the collector of its holotype, Mr. B. Guimbeau.

Physical Characteristics

Belonging to the mid-sized Phelsuma genus, males of this species can attain a total length of approximately 15.5 cm, while females are somewhat smaller, ranging from 9 to 13 cm. The gecko possesses a short, compact body. Its dorsal coloration is a striking brilliant green, often featuring a diffuse blue area on the neck. Irregularly shaped orange-red bars and spots adorn its back and tail, the tip of which may be blue. The underside is a whitish-yellow, and one or two brown, v-shaped bars are typically present on the chin. Juveniles start as greyish-brown with small white spots and develop their adult appearance after about 12 to 15 months.

Habitat and Distribution

The Mauritius lowland forest day gecko primarily inhabits large trees, such as palms and acacia species, preferring the drier and warmer parts of Mauritius. Its original habitat, the lowland forest, has been significantly reduced due to sugar cane plantations. Populations are found in areas including Chamarel, Yemen, Tamarin, and Grande Rivière Noire. The species has also been established on the Hawaiian island of Oahu.

Diet and Behavior

As a diurnal species, the Mauritius lowland forest day gecko is active during the day. Its diet is varied, consisting of insects and other invertebrates, and it also consumes soft fruits, pollen, and nectar. The gecko is described as rather shy, largely due to being heavily preyed upon by various bird species.

Reproduction

The pairing season for Phelsuma guimbeaui typically spans from March to early September. During this period, females lay up to six pairs of eggs, often in tree holes, as they are known to be egg gluers and colony nesters. The incubation period for the eggs is approximately 60 to 90 days, and the juveniles measure between 36 and 40 mm upon hatching. They reach sexual maturity after 18 to 20 months.

Conservation Status and Threats

The Mauritius lowland forest day gecko is classified as 'endangered' by the IUCN. Its limited and fragmented habitat poses a significant threat, exacerbated by the historical extinction of many endemic reptile species on mainland Mauritius. Commercial trade as a terrarium pet may also represent a threat, although the extent of this trade is not well-documented. The species is also listed on CITES Appendix II.
