The powdered glass frog or Chiriqui glass frog (Teratohyla pulverata) is a frog species in the glass frog family (Centrolenidae). The species is found from north-central Honduras south to northwestern Ecuador. Teratohyla pulverata is a small glass frog, lacking humeral spines in males, and has a lobed bulbous liver, placing it in the genus Cochranella. Adult males measure 22–24.5 mm from the snout to the vent, while the females are larger at 25.3–28.3 mm snout-vent length. The snout is rounded if seen from above, but presents a distinctly sloped profile when viewed from the side. The translucent tympanum is visible but not large, measuring about one-fifth to one-fourth of the eye's diameter; the tympanic annulus is not hidden except for the dorsal margin, which is covered by the supratympanic fold.
Their color is green above, with a rich scattering of small, white spots – hence the species' scientific name, which means "the powdered one". The back has a rough shagreen-like texture, particularly in males, where it is covered in tiny spicules. The belly is transparent and has a grained texture. Thus, the green bones and some internal organs can be observed in the living... Wikipedia →

With luck
About 10% of wildlife watchers report a Chiriqui Glass Frog sighting in Arenal Volcano National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 39 amphibians we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Chiriqui Glass Frog in Arenal Volcano National Park on a given day, against under 5% in June, August and October, the lowest months. That is one of Arenal Volcano National Park's wettest months, with about 500 mm of rain against 140 mm in April.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Chiriqui Glass Frog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 5
Of the 5 parks where we can rate Chiriqui Glass Frog sightings, Arenal Volcano National Park ranks 2nd at about 10%. The best odds are in Piedras Blancas National Park (Costa Rica, about 20%).
GBIF citizen-science records
It is estimated from how often the Chiriqui Glass Frog is recorded against all the amphibians logged in Arenal Volcano National Park (21 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.
