The little grass frog (Pseudacris ocularis) is a species of chorus frog endemic to the Southeastern United States. It is currently the smallest North American anuran and occurs in a wide variety of ephemeral and semi-permanent wetlands. Description P. ocularis is the smallest frog in North America, only reaching a maximum head-body length of 19 mm (0.75 in). It is normally pale brown, but can have a green or pink tinge. This species is further characterized by a variable dark stripe which runs through each of the frog's eyes and down the sides of its body. The Latin term ocularis translates to "of the eye" in reference to this bold ocular stripe. Habitat & Feeding This species occurs in a wide variety of ephemeral and semi-permanent wetlands in the southeastern Coastal Plain and favors grassy areas in and around cypress ponds and similar sites. It is commonly found on lower tree trunks and foliage up to a height of 1 m or more; males prefer these sites as calling perches. This species possesses the ability to rotate its head and neck more than other frog species, which is thought to aid in searching for prey or looking for a more suitable perch before leaping. The majority of food items consist of arthropods that are associated with leaf litter and/or soil—springtails, ants, thrips, palpigrades, etc. There has been some recorded research showing that adults have fed on large roaches, walking sticks, and mites. Reproduction To gain a female's attention, males will remain perched on top of grass stems or tree trunks and call. This calling is most often compared to high insect-like chirps. P. ocularis The little Grass Frog breeds in shallow, fish free wetlands, including cypress domes, marshes, bogs, wet prairies, wet flatwoods, and floodplain forests generally breeds from January to September in most of their range, but can breed year-round in Florida. Females can generally reproduce more than once per annual cycle. The eggs will usually be laid on a pond bottom or vegetation in shallow water. Females lay up to 200 eggs with 1-5 eggs per cluster. Eggs take 1–2 days to hatch and larvae take 7–70 days to metamorphose. Behavior The little grass frog's call has 2 call components (pure tone followed by a train of pulses) which is unique in Family Hylidae. P. ocularis is often active both day and night and can be active year-round
