Phelsuma standingi
A large day gecko endemic to the dry spiny forest of south-western Madagascar, reaching 20-25 cm. Its colour shifts with light intensity from brownish grey to bright green or turquoise. It is IUCN Vulnerable and threatened by collection for the pet trade.
Phelsuma standingi is a diurnal, arboreal gecko of the family Gekkonidae endemic to the dry spiny forest of south-western Madagascar. Reaching 20 to 25 cm in total length, it is among the largest living day geckos. Its colour varies greatly with light intensity, from brownish grey through bright green to turquoise, with grey to blue reticulated markings on the body and head; the head and tail are often turquoise. Hatchlings have a yellowish green head and distinct bands. The sexes are easily told apart: males have pronounced preanal pores and a bulge at the hemipenes, while females develop white endolymphatic sacs on each side of the neck that store the calcium needed for eggshells. In its habitat daytime temperatures never fall below 20 degrees C and can reach 40 degrees C in the shade, while July and August nights can drop to 13 degrees C. It lives in pairs in trees and spends long periods basking on high, well-exposed branches. Illegal collection for the international pet trade and habitat loss have left it assessed as Vulnerable by the IUCN.

Nomenclature follows global taxonomic authority databases.
Phelsuma spp. has been listed under Appendix II since February 4, 1977 (current listing effective February 1, 2017). Because it is listed under Appendix II, no registration certificate as an internationally rare wild animal or plant species is required; however, an export permit issued by the exporting country is required for importation. It is neither listed as a specified animal under the Ordinance for the Enforcement of the Act on the Welfare and Management of Animals, nor designated as a specified alien species under the Invasive Species Act.

Crickets and dubia roaches, prepared fruit-based gecko diet, nectar
Keep the basking spot at 32-35C, the cool zone at 24-31C and night-time temperatures at 22-23C. Aim for average humidity of 40-75 per cent. Although it is a dry-forest species, letting humidity fall too low causes shedding problems, so mist morning and evening. Target a UV index of 3.0-4.0 at the basking site.
As a large, active arboreal species it needs a tall enclosure of at least 60 x 60 x 120 cm even for one animal. Run thick branches and driftwood at several levels and provide a well-lit basking branch near the top. Live plants and a moisture-retentive substrate hold humidity; suspend heat lamps clear of the mesh top to prevent burns.
In the wild it takes insects and other invertebrates and will even eat smaller lizards, supplementing this with soft fruit, pollen and nectar. In captivity use a prepared fruit-based gecko diet as the base with crickets and dubia roaches alongside, dusting the feeders with calcium.
In the wild it lives in pairs in trees. Breeding pairs have been kept together successfully, but males must never be housed together. Unless breeding, a single animal or a group of females is safer, and any animals that fight should be separated at once. It is fast and thin-skinned, so it is not suited to handling.
It belongs to Phelsuma, listed on CITES Appendix II, so import requires an export permit from the exporting country; Appendix II animals need no Japanese registration certificate. The IUCN assesses it as Vulnerable, with illegal collection for the pet trade named as a threat, so choose captive-bred animals and confirm the origin of any animal you acquire.
