The hourglass treefrog also presides south of Mexico in the northern Guatemala and Belize areas.

With luck
About 10% of wildlife watchers report a Harlequin Treefrog sighting in Calakmul Biosphere Reserve on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 13 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.

GBIF citizen-science records
It is estimated from how often the Harlequin Treefrog is recorded against all the amphibians logged in Calakmul Biosphere Reserve (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.
