Calotes bachae

Calotes bachae, the Vietnamese blue-crested or Cochinchina lizard, is a colourful agamid described as a separate species in 2013. Adults reach about 9.7 cm snout–vent length and roughly 25 cm overall. Breeding males can show intense blue, green or orange tones and a pale facial stripe; compared with the similar C. mystaceus, dark brown markings are nearly absent from the upper flanks (Hartmann et al. 2013; Ecology Asia).

It occurs east of the lower Mekong in southern Vietnam and eastern Cambodia, with possible extension into southern Laos. The species uses dense forest, forest openings and heavily modified settings, including parks and gardens in Ho Chi Minh City. It is fully diurnal and mainly arboreal, feeding on a range of insects and sleeping at night near the tips of narrow branches. Its adaptability explains records from both protected forest and city greenery (Ecology Asia; Wikipedia).
