Taxonomic Comments
Based on a re-analysis of previously published molecular data, Duellman et al. (2016) restricted the name Pseudacris to eastern and Rocky Mountain species, and allocated the western species, P. cadaverina, P. hypochondriaca, P. regilla, and P. sierra to the genus Hyliola. Based on genome-wide nDNA data, Banker et al. (2020) argued that Hyliola should not be recognized because (a) the genus Pseudacris already is a monophyletic taxon without the change, and (b) the geographic separation rationale cited by Duellman et al. (2016) is insufficient as the sole criterion for splitting a long recognized monophyletic clade, causing unnecessary taxonomic instability. Use of Hyliola has not gained any traction in the systematic community, presumably because of the small number of species involved (Nicholson 2025).

Ecology & Habitat

Description

In adults, each eye is crossed by a black masklike stripe that may extend along the side of the body. The sides of the body and area near the groin have distinct light-bordered black spots. The groin is yellow. The upper side of these frogs is often reddish brown, ranging from blackish to silvery white. Maximum size is about 1.5 inches (3.9 cm) snout-vent length. Juveniles have a less distinct pattern than do adults. Breeding males have a dark throat. The breeding call is a series of high peeps (1-1.5 peeps per second). Larvae have a very high tail fin that begins just behind the eyes, and there is often a gold or brassy stripe along each side of the back. Larvae are up to about 1.7 inches (4.3 cm) long.

Habitat

Ornate chorus frogs inhabit sandhills, pine flatwoods, upland pine forests, and other habitats up to at least several hundred meters from breeding pools. They burrow into the ground (often among herbaceous plant roots) when not active on the surface. Adults are seldom observed except when breeding. Eggs are attached to plant stems in flooded fields, sinkhole ponds, pine barren ponds, Carolina bays, and cypress ponds.

Ecology

As is true of many amphibians, the breeding characteristics of ornate chorus frogs are fairly well documented, but their habits in nonbreeding upland habitats are poorly known.

Population turnover nearly annual in South Carolina (Caldwell 1987).

Reproduction

Clusters of up to about 100 eggs (usually a few dozen) are laid from late fall to early spring (peak usually in winter). Larvae hatch in about a week and metamorphose into small frogs about 3-4 months later. Individuals become sexually mature in 1 year in South Carolina (Caldwell 1987). Little or no recruitment occurs during drought periods (Pechmann et al. 1991).
