Common Tree Frog/Four-lined Tree Frog

<em>Polypedates leucomystax</em>, commonly known as the four-lined tree frog or common tree frog, is a medium-sized arboreal frog in the family Rhacophoridae, widely distributed across South and Southeast Asia. Its range extends from Bangladesh and northeastern India through Myanmar, Thailand, Vietnam, the Philippines, Malaysia, and Indonesia, making it one of the most broadly distributed tree frog species in the region. This species typically inhabits tropical and subtropical moist forests, forest edges, agricultural areas, gardens, and urban environments, demonstrating a high tolerance for human-modified habitats. The dorsal surface is pale brown to cream, typically marked with four dark longitudinal stripes that give the species its common name, though considerable color variation exists. <em>Polypedates leucomystax</em> is predominantly arboreal and nocturnal, descending to breed in temporary pools, rice paddies, and other standing water bodies. It produces foam nests that are attached to vegetation overhanging water, within which eggs develop before tadpoles fall into the water below. The diet consists primarily of insects and other small invertebrates. The species is currently assessed as Least Concern by the IUCN, with a stable and widespread population. Biological traits such as average lifespan, body length, and weight remain poorly documented at the species level in the scientific literature.
