| Green Treefrog, Hyla cinerea (Schneider, 1792). Photographed in central Florida. Green Treefrogs range from Maryland and Virginia southward to Florida and westward to east Texas. They follow the Mississippi River Valley north into southern Illinois, southern Indiana, and western Kentucky. The Green Treefrog has also been introduced into Puerto Rico. Adults can reach 64 mm in length. These frogs use swamp forests, but also use the edges of almost any body of sluggish water that has bushes or trees at the perimeter. Perhaps they are most common in cypress swamps. Populations living in coastal areas may use brackish water. The voice is bell-like, and choruses have been described as sounding like a heard of cows with bells on. Reproduction occurs from March to October. This species may hybridize with the Barking Treefrog, Hyla gratiosa. |

| The Mountain Treefrog, Hyla exima (Baird, 1854), Photographed in Chapala, Mexico. The species occurs in the highland pine forests of central Arizona and New Mexico, the Huachuca Mountains of southern Arizona, in the Sierra Madre Occidental of northwestern Mexico, and is widespread in the southern part of the Mexican Plateau, the Sierra Madre Oriental, and the Cordillera Volcanica in central Mexico. |

| Pine Woods Treefrog, Hyla femoralis Bosc, 1800. Photographed in Alachua Co., Florida, USA. The species is widespread on the Atlantic and Gulf Coastal Plains from Virginia to Louisiana. The Pine Woods Treefrog uses forest and forest edge habitats and lays its eggs in ephemeral pools. The eggs are attached to submerged vegetation and hatch after about three days. Breeding occurs between April and October. It has the reputation of calling from the forest canopy. |

| Gray Treefrog, Hyla chrysoscelis-versicolor complex. Central Illinois, USA. These frogs are also known as Cope’s Treefrogs. Their gross morphology is identical but chrysoscelis is a diploid (2N) species, while versicolor is a tetraploid (4N) species. They range from southern Canada to central Texas and northern Florida. |
