The Amazonian poison frog (Ranitomeya ventrimaculata), known in French as dendrobate à ventre tacheté, is a species of poison dart frog. It is native to South America, where it can be found in Brazil, southeastern Colombia, Ecuador, French Guiana, and Peru.

It is therefore often included among the poison dart frogs, although its toxin is comparatively weak. R. ventrimaculatus produces its poison by ingestion of a species of mite.
The frog is active during the day. It grows to a size of about 20 millimetres (0.79 in), with males smaller than females. Its base color is black, and it has yellow lines or dots on the back, whereas the belly has bluish or grayish color with interspersed black patches (hence the name "ventrimaculatus"); the color of the belly continues into a netlike pattern on the legs.
R. ventrimaculata reach adulthood at an age of six months. The females attach four to eight eggs to leaves beneath the water level, where they are... Wikipedia →

Possible
About 20% of wildlife watchers report a Reticulated Poison Frog sighting in Amacayacu National Natural Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 8 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.
March and November
In those months about 40% of wildlife watchers report a Reticulated Poison Frog in Amacayacu National Natural Park on a given day, against under 5% in June–July, September and December–February, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Reticulated Poison Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 2 parks where we can rate Reticulated Poison Frog sightings, Amacayacu National Natural Park has the highest daily chance: about 20%. Next come Yasuní National Park (Ecuador, about 20%).
GBIF citizen-science records
It is estimated from how often the Reticulated Poison Frog is recorded against all the amphibians logged in Amacayacu National Natural Park (8 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.
