About Dasia olivacea Gray, 1839
Dasia olivacea was first described by Gray in 1839. Mature individuals of this species have a green back, with bronze-colored scales along their flanks, and 12 bands of ocelli (eye-like spots) that stretch across the body from side to side. The head is mainly dark olive-green with black markings, while the underside of the head ranges from bluish green to yellowish green. Dasia olivacea occurs in Southeast Asia, south of roughly 15° north latitude. Its range includes parts of Laos, Malaysia, Myanmar, Thailand, Singapore, and Vietnam. It is also found across the entire island of Borneo, covering Sarawak, Kalimantan, and Brunei, plus the Indonesian islands of Bali, Java, Sumatra, and other smaller islands, as well as India's Andaman and Nicobar Islands. The species was originally recorded from only one location in Cambodia. The northernmost confirmed record of D. olivacea is possibly at the Sakaerat Environmental Research Station, located in Nakhon Ratchasima Province, eastern Thailand. In terms of ecology, D. olivacea lives almost entirely in trees, and only rarely descends to the ground to nest or move between different trees. Females can lay eggs multiple times per year, with clutches containing up to 14 eggs, and an incubation period of 69 days. Due to its very wide distribution and ecological flexibility, D. olivacea is classified as a species of Least Concern on the IUCN Red List.
