Phelsuma barbouri

Barbour's Day Gecko (Phelsuma barbouri)

Barbour's day gecko, scientifically recognized as Phelsuma barbouri, is a distinctive lizard species native to the central highlands of Madagascar. This middle-sized gecko is diurnal, meaning it is active during the day, and prefers a terrestrial lifestyle, typically found dwelling on rocks within its savanna habitat.

Physical Characteristics and Habitat

Reaching a total length of approximately 13.5 cm (5.3 inches), P. barbouri exhibits a brownish-green to dark green body coloration. Distinctive markings include a dark brown dorso-lateral stripe and a dark brown lateral stripe that extend from the head to the tail. The extremities are generally brown, and its tail is a uniform green and slightly flattened. The species inhabits the Ankaratra Mountains in central Madagascar, at altitudes ranging from 1,600 to 2,640 meters. Its habitat is characterized by harsh conditions, with significant temperature variations between day and night, and across seasons. Maximum daytime temperatures can reach 30°C, while nights are often cool and foggy.

Diet and Behavior

Barbour's day gecko is an omnivore, feeding on a diet of various insects, other invertebrates, and nectar. Behaviorally, P. barbouri often forms small groups. A notable adaptation is its habit of flattening its body to maximize sun exposure, enabling it to reach its preferred body temperature. During cooler periods, such as at night or in the early morning, its coloration darkens, becoming brighter when it is actively basking.

Reproduction

Reproduction in P. barbouri involves the female gluing her eggs under stones. It is not uncommon for multiple females to deposit their eggs in the same location, leading to aggregations of up to 50 eggs. At a temperature of 28°C (82°F), the young geckos hatch after approximately 55 days, with neonates measuring about 32 mm (1.3 inches) in length.
