The Copan brook frog (Duellmanohyla soralia) is a species of frog in the family Hylidae found in northeastern Guatemala and northwestern Honduras, specifically in the Sierra del Merendón, Sierra de Omoa, Sierra de Caral, and Sierra Espíritu Santo ranges. The colouring of this species is very distinctive and the specific name soralia comes from the resemblance of its markings to the vegetative structures on some crustose lichens.
The Copan brook frog is a small frog, the males growing to about 32 mm (1.3 in) and the females to 38 mm (1.5 in). The snout is very blunt and the prominent eyes have red irises.

The ventral surface is yellow and the outer surface of the fore limb has a patterning of white streaks.

Possible
About 30% of wildlife watchers report a Copan brook frog sighting in Cusuco National Park on a given day, based on 61 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 12 amphibians we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 50% of wildlife watchers report a Copan brook frog in Cusuco National Park on a given day, against under 5% in February–March, May and August, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Copan brook 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.
Only Cusuco National Park, in our data
Cusuco National Park is the only park on Wallace's Line with enough records to rate Copan brook frog sightings: about 30% of wildlife watchers there report one on a given day.
Same family: Hylidae

GBIF citizen-science records
It is estimated from how often the Copan brook frog is recorded against all the amphibians logged in Cusuco National Park (61 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.
