Description
Bawangling Cave Gecko
Scientific Name: Goniurosaurus bawanglingensis
Common Name: Bawangling Cave Gecko
Species Overview
Size: Adult Bawangling Cave Geckos typically reach 7–8 inches (18–20 cm) in total length, including the tail. They have slender bodies, long limbs, and slightly flattened heads, with large eyes adapted for nocturnal life.
Appearance: The Bawangling Cave Gecko is a visually striking species with a deep mahogany to dark violet base colour crossed by bright orange or yellow bands. The tail is distinctly ringed, often showing alternating dark and pale bands. Their eyes are large and golden or silver with vertical pupils, enhancing their vision in low light. The body is covered in fine granular scales, and the contrast between the dark background and vibrant bands gives this species an unmistakable appearance.
Distribution: Endemic to Hainan Island, China, where it is found primarily in and around the Bawangling National Nature Reserve, a humid subtropical region characterized by limestone formations and forested slopes.
Habitat: In the wild, Bawangling Cave Geckos inhabit rocky crevices, limestone caves, and forest floors near water sources. They prefer humid microhabitats with moderate airflow and shelter from direct light. In captivity, they thrive in naturalistic terrariums that maintain high humidity and provide multiple hiding and climbing opportunities.
Behaviour: These geckos are nocturnal, secretive, and deliberate in movement. They rely on cover and camouflage rather than speed, often remaining motionless when threatened. While not aggressive, they can be defensive when handled, so interaction should be minimal. Once settled, they become confident feeders and display well under dim lighting.
Captive Care
Enclosure: Provide an enclosure of at least 24 inches × 18 inches × 18 inches (60 × 45 × 45 cm) for a single adult. Use a naturalistic layout with rocky hides, bark, and leaf litter to replicate a cave-like environment. Bioactive setups with moss and ferns can help maintain stable humidity. A substrate blend of soil, sand, and clay works well for burrowing and moisture retention.
Temperature & Humidity: Maintain a daytime ambient temperature of 75–80°F (24–27°C), with a gentle basking area up to 84°F (29°C). Nighttime temperatures can safely drop to 68–72°F (20–22°C). Keep humidity between 70–85%, achieved through daily misting and the use of mossy hides. Ensure adequate airflow to prevent fungal growth.
Lighting: Provide low-level UVB lighting (2–5%) on a 12-hour day/night cycle. While primarily nocturnal, they benefit from natural light gradients to support healthy circadian rhythms and vitamin D3 synthesis.
Diet: Offer a varied diet of gut-loaded crickets, roaches, and silkworms, supplemented occasionally with waxworms or black soldier fly larvae. Dust insects with calcium and multivitamin supplements. Juveniles should be fed daily; adults every 2–3 days.
Behaviour in Captivity: Bawangling Cave Geckos are calm but shy and prefer to stay within cover. They thrive in low-light, humid conditions and show natural foraging behaviour in the evening. With consistent care and stable conditions, they adapt well and can live over 10 years in captivity.
Special Considerations: This species is humidity-sensitive—avoid overly dry setups. Always use thermostats for heat regulation and ensure multiple secure hides. Because of their shy nature, avoid frequent handling.
Taxonomy Note
The Bawangling Cave Gecko (Goniurosaurus bawanglingensis) belongs to the family Eublepharidae, which also includes Leopard Geckos and African Fat-tailed Geckos. Goniurosaurus species are collectively known as “Cave Geckos,” a group distinguished by their eyelids, terrestrial habits, and vibrant banded colouration. G. bawanglingensis is closely related to G. hainanensis but is geographically and visually distinct, featuring broader head proportions and more vivid banding.
Genetics Note
There are currently no recognized morphs or genetic colour variants of Goniurosaurus bawanglingensis. However, natural variation exists in band thickness and overall hue—some individuals appear more orange, while others display pinkish or golden tones depending on locality and environmental factors.
