Hyla Arenicolor, commonly known as the Canyon Treefrog, is a species of small arboreal frog found in the southwestern United States and Mexico. There are several synonyms used for this species, including Dryophytes arenicolor, Pternohyla arenicolor, and Hyla arenicola. All of these names refer to the same species, and are often used interchangeably in scientific literature. The Canyon Treefrog is known for its distinctive call, which can be heard during the breeding season in rocky canyons and riparian habitats. Despite being a common sight in its native range, this species faces threats from habitat loss and climate change, and is classified as a species of least concern by the IUCN.
