Leptodactylus fragilis, known under many common names such as the Mexican white-lipped frog, American white-lipped frog or simply white-lipped frog, is a species of leptodactylid frog.

With luck
About 10% of wildlife watchers report a Mexican White-lipped Frog sighting in Santa Rosa National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 14 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Mexican White-lipped Frog in Santa Rosa National Park on a given day, against under 5% in January–March, May and July–November, the lowest months. That is one of Santa Rosa National Park's wettest months, with about 330 mm of rain against almost none in February.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Mexican White-lipped Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
3rd of 5
Of the 5 parks where we can rate Mexican White-lipped Frog sightings, Santa Rosa National Park ranks 3rd at about 10%. The best odds are in Palo Verde National Park (Costa Rica, about 20%) and Soberanía National Park (Panama, about 20%).
GBIF citizen-science records
It is estimated from how often the Mexican White-lipped Frog is recorded against all the amphibians logged in Santa Rosa National Park (5 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.
