Ameerega simulans is a small to medium-sized species of poison dart frog that lives in Peru in Puno described in 1998. It can be found at an elevation of 400–600 m. Females with average size of 23.6–27 mm are slightly larger than males that measure on average 18.9–22.4 mm (a sign of sexual dimorphism).
This frog lives in lowland and submontane rainforests, where it has been observed on the leaf litter. Scientists saw the frog between 300 and 600 meters above sea level. The frog's known range includes two protected parks: Bahuaja-Sonene National Park and Manu Biosphere Reserve.
The female frog lays eggs on the ground. After the eggs hatch, the male frog carries the tadpoles to water. The IUCN classifies this frog as least concern of extinction. It suffers from localized habitat loss in some parts of its range, usually associated with agriculture and livestock cultivation. Wikipedia →

With luck
About 10% of wildlife watchers report a Río Madre de Dios Poison Frog sighting in Manu National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 55th most-seen of the 67 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.
January and March
In those months about 20% of wildlife watchers report a Río Madre de Dios Poison Frog in Manu National Park on a given day, against under 5% in April–May and July–December, 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 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Río Madre de Dios Poison Frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Manu National Park, in our data
Manu National Park is the only park on Wallace's Line with enough records to rate Río Madre de Dios Poison Frog sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Ameerega
The closest relatives of the Río Madre de Dios Poison Frog that you can see in Manu National Park (genus Ameerega) are Three-striped Poison Frog (about 30%), Pale-striped Poison Frog (about 20%) and Manú Poison Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Río Madre de Dios Poison Frog is recorded against all the amphibians logged in Manu National Park (6 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.
