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 →

With luck
About 10% of wildlife watchers report a Northern Leopard Frog sighting in Toronto on a given day, based on 144 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 12 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April to September
In those months about 10% of wildlife watchers report a Northern Leopard Frog in Toronto on a given day, against under 5% in October to March, the lowest months.
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.
3rd of 6
Of the 6 cities where we can rate Northern Leopard Frog sightings, Toronto ranks 3rd at about 10%. The best odds are in Montreal (Canada, about 20%) and Minneapolis [Saint Paul] (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Northern Leopard Frog is recorded against all the amphibians logged in Toronto (144 verified sightings), 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.
