Lithobates pipiens formerly Rana pipiens, commonly known as the northern leopard frog, is a species of leopard frog from the true frog family, native to parts of Canada and the United States. It is the state amphibian of Minnesota and Vermont.
The northern leopard frog is a fairly large species of frog, reaching about 11 cm (4.3 in) in snout-to-vent length. It varies from green to brown in dorsal color, with large, dark, circular spots on its back, sides, and legs. Each spot is normally bordered by a lighter ring. A pair of dorsolateral folds starting from the back of the eye runs parallel to each other down the back. These dorsolateral folds are often lighter or occasionally pinkish in colour. Also, a pale stripe runs from the nostril, under the eye and tympanum, terminating at the shoulder. The ventral surface is white or pale green. The iris is golden and toes are webbed.
Tadpoles are dark brown or grey, with light blotches on the underside. The tail is pale tan. The northern leopard frog has several different color variations, with the most common two being the green and the brown morphs, with another morph known as the burnsi morph. Individuals... Wikipedia →

Possible
About 30% of wildlife watchers report a Northern Leopard Frog sighting in Riding Mountain National Park on a given day, based on 52 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 6 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
August
In that month about 50% of wildlife watchers report a Northern Leopard Frog in Riding Mountain National Park on a given day, against under 5% in February–March and December, the lowest months. That is one of Riding Mountain National Park's wettest months, with about 70 mm of rain against 20 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Northern Leopard Frog sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 6
Of the 6 parks where we can rate Northern Leopard Frog sightings, Riding Mountain National Park ranks 2nd at about 30%. The best odds are in Voyageurs National Park (United States, about 40%).
GBIF citizen-science records
It is estimated from how often the Northern Leopard Frog is recorded against all the amphibians logged in Riding Mountain National Park (52 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.
