Distribution

A submontane and montane species, found at elevations of 1000m and above. This species is tolerably common at localities such as Nuwara Eliya, Pattipola, Ohiya, Horton Plains, and Adam's Peak

Description

Head is one and a half times width. A row of spines above and at the back of tympanum. Adult male is with swollen cheeks. Gular sacs are not developed. Mid body scale rows are 42-50. Ventrals are larger than dorsals. Dorsum is green unpatterned or with black edged, cream transverse bars or eye-like spots. Head with black markings. Venter is pale green.

Ecology

This species is largely arboreal,[1] inhabiting tree trunks, hedges, and shrubs, where it hunts for insects and worms by day. In Horton Plains C. nigilabris can be found residing on the gorse bushes (Ulex europeus) and Rhododendron leaves to hunt the insect prey (particularly bees) that gets attracted to the flowers.[1][2]

Reproduction

Lays up to 4 eggs, measuring 17-23 mm in length and 10-13 mm in width. Hatchlings have ean SVL of 35-50 mm[3]. Two breeding seasons can be observed from November-December and February to March. Hachlings can be observed following the egg laying in the breeding months after an approximate two months of incubation.
