Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca).
When feasible, this species utilizes caves for thermal refugia during the coldest months of the year. [8] The pickerel frog is a trogloxene species, meaning they occur in caves, but are unable to complete their life cycles there. Though they are most abundant in caves during the winter, they are active deep within caves at almost any time of year.

It is known under numerous common names, including common tree frog, four-lined tree frog, golden tree frog [2] or striped tree frog. Many past authors have united it with the common Indian tree frog in P. maculatus (or Rhacophorus maculatus , as was common in older times), but today they are generally considered distinct species.
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.
