Overview
The Southern Cricket Frog (Acris gryllus) is a tiny, energetic treefrog relative that has completely abandoned arboreal climbing in favor of a terrestrial, semi-aquatic wetland life. Ubiquitous across the sunny marshes and cypress swamps of the American Southeast, this thumb-sized leaper fills spring and summer nights with a vibrant chorus of metallic clicking calls that sounds exactly like two glass marbles being clicked rapidly together.
Biology and Physical Characteristics
Acris gryllus has a slender, warty body with extremely long hind legs and reduced toe pads compared to typical treefrogs. Its dorsal pattern is highly variable, featuring shades of olive, grey, and tan accented by a bold, dark triangle between the eyes and a vivid green or reddish-brown stripe down the center of the back. Its thighs display a clean, sharp dark stripe, and its snout is distinctly pointed.
Behavior and Ecology
A daytime sunbather, the Southern Cricket Frog sits along sunny, grassy margins of freshwater ponds and ditches. When startled by a heron or snake, it executes astonishing, acrobatic leaps spanning up to sixty times its own body length, skittering across the water’s surface in multiple rapid bounces before diving into aquatic vegetation. Breeding choruses can number in the thousands during warm summer rains.
Conservation and Human Impact
Classified as Least Concern by the IUCN, Acris gryllus remains widespread and abundant across the Gulf and Atlantic coastal plains. However, it is vulnerable to wetland drainage for development, pine monoculture plantation forestry, and chemical pollution from road runoff and agricultural pesticides.
Interesting Factoid
Relative to its tiny one-inch body, the Southern Cricket Frog is one of the greatest long-jumpers in the animal kingdom; it can leap over five feet in a single bound—the human equivalent of jumping across a football field in one hop.
