Strongylopus fasciatus, also known as the striped stream frog, striped grass frog, striped rana, striped long-toed frog or long-toed grass frog is a species of frog in the family Pyxicephalidae. It is endemic to southern Africa.
Strongylopus fasciatus is a small, long legged frog with a pointed snout. Its distinguishing features are the parallel yellow and brown longitudinal stripes along its back, with longitudinal dark stripes along its legs. It has a white belly and the males have yellow throats. The pupils are horizontal. It also has very long toes and, when crouched, the fourth toe on the rear feet extends past the front feet.
The call of Strongylopus fasciatus is a sharp "pip" which can be made singly or in a series of three or four calls. Strongylopus fasciatus occurs the Western Cape Province east through eastern South Africa to borders of Lesotho and Eswatini, then north into Zimbabwe, western Mozambique and south-western Zambia, its presence in Botswana has yet to be confirmed. In the Highveld of central South Africa it appears to be localised but extends as far west as the eastern Free State.

With luck
About 10% of wildlife watchers report a Striped Stream Frog sighting in Addo Elephant National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 8 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Striped Stream Frog is recorded against all the amphibians logged in Addo Elephant National Park (12 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
