Standing’s Day Gecko

🔤 Taxonomy

Phelsuma standingi is the accepted scientific name. No subspecies are currently recognized. The English names most often used are Standing’s day gecko and banded day gecko; the German trade name is Standing’s Taggecko.

📌 Description

Standing’s day gecko is one of the larger Phelsuma: adults usually reach 20-25 cm and can live 15-20 years. Juveniles show strong dark bands over blue-green colour, while adults become greyer or greenish with a broken reticulated pattern. Broad adhesive toe pads make it an agile climber.

This is an alert display animal. It can learn to approach a feeding ledge, but its skin tears easily and the tail can be lost. A tall, bright enclosure, measured UVB, reliable ventilation, and restrained feeding matter more than attempts to tame it.

🌍 Distribution

The species has a restricted range in southwestern Madagascar, including dry deciduous forest around Zombitse-Vohibasia and nearby areas of the Atsimo-Andrefana region. It uses tree trunks, hollow limbs, and sunlit vegetation in a landscape with a pronounced cooler dry season and warmer wet season.

Wild weather is not an enclosure programme. The useful lesson is to offer warm exposed perches, cooler shaded retreats, drinking droplets, and a daily drying cycle rather than keeping every surface hot or wet.

⚖️ Legal status

Checked on 2026-08-30: Phelsuma standingi is covered by the Phelsuma listing in CITES Appendix II and by Annex B of the EU wildlife-trade regulation. It is not a European native species, so the Bern Convention is not relevant. Madagascar has also been subject to species- and trade-specific export controls; an Appendix-II listing is not proof that a particular animal was legally exported.

Buy established captive-bred stock and retain the invoice, breeder identity, hatch or transfer record, photographs, and any import documents. National rules on ownership, registration, sale, breeding, and transport can add requirements.

🤌 Husbandry

One adult needs at least 60 x 60 x 120 cm, with more space strongly preferred. House it singly unless a planned breeding introduction is being managed by an experienced keeper. Males fight, and an apparently quiet pair can still leave the female unable to feed or rest.

Quarantine a newcomer for 60-90 days in a separate room when possible. Use dedicated tools and washable climbing furniture, record weight, food, droppings, and sheds, and arrange reptile-veterinary testing for weight loss, diarrhoea, mites, or uncertain origin. Move the gecko in a clear container or removable cork tube; never grab it.

💡 Lighting

Provide 11 hours of light in winter and up to 13 in summer, changing gradually. Bright visible light supports normal daytime activity and plant growth. UVB is required: arrange a linear lamp so the highest routinely used open perch receives about UVI 3-4, with foliage and cork reducing exposure to near zero in retreats.

Lamp percentage alone does not determine exposure. Mesh, reflector, distance, and lamp age all change UVI, so measure with a Solarmeter 6.5 when possible and follow the manufacturer’s replacement interval. Do not put every perch directly beneath heat and UVB.

🌡 Heating and temperature

Create a 32-35°C basking perch near the top, daytime air of 24-29°C, and a shaded lower zone of 22-25°C. Nights can fall to 20-23°C. Use one or more thermostatically controlled overhead lamps sized to warm a broad section of branch without heating the whole roof.

Measure the perch surface with an infrared thermometer and air temperatures with digital probes. Persistent temperatures above 30°C throughout the enclosure cause dehydration and heat stress. A modest winter reduction in day length and ambient temperature can reflect the natural season, but deliberate cooling is not appropriate for juveniles, thin animals, sick animals, or new arrivals.

💧 Humidity and water

Allow humidity to move roughly between 40% and 75%: lower around the warm perch, rising after evening or morning misting and then falling as surfaces dry. Provide good cross-ventilation. Constantly wet glass and stale air are not a substitute for hydration.

Mist leaves and branches so the gecko can lick droplets, and keep a small clean water cup on an elevated ledge. Refresh it daily. Increase access to a humid retreat during shedding, but investigate repeated retained shed, sunken eyes, or loss of skin elasticity instead of soaking this delicate arboreal gecko routinely.

🌿 Enclosure and decoration

Fill the vertical space with branches, cork tubes, broad trunks, vines, and robust live plants. Provide horizontal and diagonal basking routes as well as shaded upper retreats. Every perch must be anchored; cable holes and door gaps must be sealed.

A 5-10 cm layer of organic topsoil and coconut fibre with leaf litter buffers humidity and cushions falls. Avoid fertilized soil, resinous wood, sticky traps or tape, sharp wire, and unstable stone. Dense planting should break lines of sight without stopping airflow. Keep a removable cork tube available for safe transfers.

🪳 Feeding

Offer adults varied, gut-loaded insects two or three times weekly and a nutritionally complete fruit/nectar gecko diet about once weekly. Juveniles eat smaller meals more often. Appropriate prey includes crickets, roach nymphs, locusts where legal, silkworms, and black soldier fly larvae; prey should be no wider than the space between the eyes.

Lightly dust insects with plain calcium at most feeds when good UVB is available. Use a multivitamin, including appropriate vitamin A and D3, only at the product’s recommended interval; do not layer several fortified powders over an already complete gecko diet. Gut-load insects for 24-48 hours, remove escaped prey, and discard prepared diet before it ferments.

Obesity is common when sweet food and fatty larvae are overused. Monitor body condition and female calcium reserves rather than leaving fruit mixture available continuously.

🥚 Breeding notes

Females usually produce one or two hard-shelled eggs and may lay repeated clutches. Unlike many day geckos, the eggs are not normally glued firmly to the surface. A planned pair needs a larger enclosure, multiple feeding stations, and a separate home ready for either animal.

Keeper protocols commonly incubate at 28-29°C for about 55-75 days. Do not rotate a newly found egg. Repeated laying can cause calcium depletion or egg binding; stop breeding and seek an experienced reptile veterinarian if a female loses condition, strains, or remains distended. House hatchlings separately from adults.

🩺 Common problems

Important preventable problems include thermal burns or heat stress, dehydration, dysecdysis, metabolic bone disease, obesity, intestinal parasites, territorial injuries, egg binding, and skin tears during capture. Weak grip, a soft jaw, tremors, sunken eyes, persistent hiding, weight loss, abnormal droppings, retained shed, wounds, or laboured breathing require prompt review of the setup and veterinary assessment.

Do not pull retained skin, apply oils, or treat parasites without a diagnosis. Day-gecko skin is especially easy to damage.

📌 Conclusion

Standing’s day gecko suits an intermediate keeper who wants an active, long-lived display reptile and can provide a genuinely tall enclosure. The main failures are uniform heat, permanently wet air, poor UVB measurement, and forced handling; all four should be solved before purchase.
