Common Name: Little Grass Frog
Scientific Name: Pseudacris ocularis
Family: Hylidae – Tree Frog family
Locations: United States – Alabama, Florida, Georgia, North Carolina, South Carolina, and Virginia
Size: .4 – .7 inches (11 – 20 mm)

The Little Grass Frog is the smallest frog in all of North America. While it is technically in the Tree Frog family – Hylidae, they are not as arboreal as other species of tree frogs. They can still climb up to 5 feet high.

Breeding takes place for the Little Grass Frog from January to September in most of their range but in Florida, they can breed all year long. Breeding generally follows heavy rain events. They lay their eggs in shallow, rain-filled wetlands, ditches, and ponds. Reproduction is pretty standard for the frog. Males will call out from the rain-filled areas, trying to attract females. Females will select a male and then they will mate. The females lay around 100 eggs. How do these females carry all those eggs at their small size? I don’t know. Neither of the parents will perform any care for their offspring.

Common Name: Australian Green Tree Frog, White’s Tree Frog
Scientific Name: Litoria caerulea
Family: Hylidae – Tree Frog family
Locations: Australia, Indonesia, and Papua New Guinea
Introduced Location: United States – Florida
Size: 4 inches (10 cm)

The Australian Green Tree Frog is not always green but can be brown or blueish. They change their colors to match their surroundings. The tree frog is a common frog in the pet trade due to their hardiness and ease of care. They can be referred to as the White’s Tree Frog or Dumpy Tree Frog. They are named the Dumpy Frog after the fat deposits that can form on obesity frogs’ head. If taken care of, the frogs can live over 15 years long. They have a huge appetite so if housing the Australian Green Frog with other frogs, make sure they are the same size. It is believed that the pet trade introduced the species to Florida but luckily, the frogs haven’t been spotted in Florida since 2010. Please never release your pets into the wild as it can have bad consequences.

Breeding for the Australian Green Tree Frog occurs during the rainy season for November to February. Males will call to attract females. Mating is aquatic and up to 2000 are laid. No parent provides any care. The eggs hatch shortly into tadpoles that take around 6 weeks to complete their metamorphosis before winter arrives.
