Humerana lateralis is a species of frog in the family Ranidae. It is found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. It is commonly known as Kokarit frog or yellow frog. Placed in Rana when this was still loosely circumscribed, it was since assigned to the "water frog" genus Pelophylax. However, it is not clear whether this is the most appropriate treatment, and the Kokarit frog might rather belong in Hylarana. In 2015, it was classified into Humerana based on phylogenetic evidence. The supposed species Rana nigrolineata was recently determined to be a junior synonym of H. lateralis.
Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical dry lowland grassland, moist shrubland, plantations, swamps, freshwater marshes, intermittent freshwater marshes, ponds, and seasonally flooded or irrigated agricultural land. It is not considered threatened by the IUCN.
In parts of Cambodia north and east of the Mekong River, it is collected for human consumption in localities such as Snuol District, Kratie Province. Wikipedia →

Possible
About 20% of wildlife watchers report a Kokarit Frog sighting in Cat Tien National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 21 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Kokarit Frog in Cat Tien National Park on a given day, against under 5% in January–April, July and September–November, the lowest months. That is one of Cat Tien National Park's wettest months, with about 340 mm of rain against 15 mm in February.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Kokarit Frog sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Kokarit Frog sightings, Cat Tien National Park has the highest daily chance: about 20%. Next come Kaeng Krachan National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Kokarit Frog is recorded against all the amphibians logged in Cat Tien National Park (18 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.
