Description: Gray treefrogs (Hyla versicolor) are 1.25 - 2 inches long. Their coloration is highly variable but usually gray or green with irregular markings on the back. They are characterized by a white spot under the eye, warty skin, and yellow-orange on the concealed surfaces of the thigh. 

This species is indistinguishable from the Cope's gray treefrog except by call or chromosome analysis. The gray treefrog has 48 chromosomes, while Cope's gray treefrog has 24

Habitat: They are found in varied habitats with small trees or shrubs. They are rarely found outside of the breeding season as they forage in the canopy.

Life History: Females lay clusters of 10 to 30 eggs that are attached to vegetation near the surface of the water. The eggs hatch in 3 - 6 days. Metamorphosis of tadpoles takes from 1 - 2 months and maturity is reached in 2 years.

Range: They are known to occur in the far southwest corner of the state.
