The Canyon Tree Frog or Arizona Tree Frog (Hyla arenicolor) is a species of tree frog native to the rocky plateau areas of southern United States, primarily in the states of New Mexico and Arizona, but it also ranges to neighboring states of Utah, Texas and Colorado, and as far south as the Mexican states of Michoacán, México, Guanajuato, Guerrero, and Oaxaca.
Canyon tree frogs grow to 2-2.25 inches in length, and are typically a brown
-brown, or grey-green
in color, often with darker colored blotching. They can vary quite a bit, but usually match the soil or rock coloration of their native habitat to serve as camouflage
. Those from limestone
habitats being lighter colored, those from regions composed mostly of granite
can even be pink
in coloration. Most have bright yellow
in their groin
region, and faded banding on their legs.
Like most tree frogs, canyon tree frogs are mostly nocturnal
. They are typically found in semi-arid, rocky habitats near a permanent water source. Breeding occurs during the spring rains, and large, floating egg
masses of 100 or more eggs are laid on the water. During periods of low rainfall, the frogs will take refuge in rock crevices.
