[2] P. ocularis is the smallest frog in North America, only reaching a maximum head-body length of 19 mm (0.75 in).

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.

[3] 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.

[4] 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.

[6] The majority of food items consist of arthropods that are associated with leaf litter and/or soil—springtails, ants, thrips, palpigrades, etc.

[8] To gain a female's attention, males will remain perched on top of grass stems or tree trunks and call.
