Phyllomedusa camba or the black-eyed monkey frog is a species of frog in the subfamily Phyllomedusinae. It is found in Bolivia, Brazil, and Peru. It has been observed between 280 and 1000 meters above sea level. The adult frog measures 60.8 mm (2.39 in) to 69.6 mm (2.74 in) in snout-vent length. It has disks on its toes for climbing. The skin of the dorsum is green with yellow marks around its eyes. It has pink-white spots on its flanks and white spots on the inner surfaces of its legs. Parts of its legs and middle are purple.
This frog is nocturnal. The frogs have been observed in primary forest and in secondary forest. When it is time to lay eggs, the frogs leave the forest and go to a swamp if they can. The female frog makes a nest out of foam on a leaf. When the eggs hatch, they fall into the water below.
Scientists say this frog is not endangered because of its large range and because of its at least partial tolerance to altered habitats. The scientific name of this frog, "camba," comes from the indigenous people who live in Bolivia. Wikipedia →

Possible
About 20% of wildlife watchers report a Black-eyed Monkey Frog sighting in Manu National Park on a given day, based on 31 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 67 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.
December and January
In those months about 30% of wildlife watchers report a Black-eyed Monkey Frog in Manu National Park on a given day, against under 5% in April and November, the lowest months. Those are among Manu National Park's wettest months, with about 240 mm of rain a month against 60 mm in August.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Black-eyed Monkey Frog sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 2
Of the 2 parks where we can rate Black-eyed Monkey Frog sightings, Manu National Park ranks 2nd at about 20%. The best odds are in Tambopata National Reserve (Peru, about 30%).
Same genus: Phyllomedusa
The closest relatives of the Black-eyed Monkey Frog that you can see in Manu National Park (genus Phyllomedusa, Monkey Frogs) are White-lined Leaf Frog (about 40%) and Waxy Monkey Treefrog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-eyed Monkey Frog is recorded against all the amphibians logged in Manu National Park (31 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.
