Threats to natives: None known.

Species Account: This beautiful gecko is native to Madagascar and commonly seen in the pet trade. Adults are bright green with an orange stripe between the eye and nostril. Additional orange spots may be present on the head and back. The scales on the back and sides are granular, and the belly is whitish. The skin is very delicate and easily torn. Males may exceed 28 cm (11 in) in length) and are aggressively territorial. This diurnal species is highly arboreal and can be observed on the walls of buildings and on tree trunks. They feed on insects, pollen, sap, and exudate from overripe fruit (Bartlett and Bartlett 1999). The species has been released in several areas of Florida, but the only population that appears to be established occurs in the Florida Keys (Krysko et al. 2003a).

Habitats: Low density suburban development, areas peripheral to core urban areas, and small towns, Rockland Hammock
