The legs are barred with dark brown and there are red or orange patches in the armpits and groin. The fingers and toes are unwebbed.

Likely
About 50% of wildlife watchers report a Steindachner's Dwarf Frog sighting in Brownsberg Nature Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 18 amphibians we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
April
In that month about 70% of wildlife watchers report a Steindachner's Dwarf Frog in Brownsberg Nature Park on a given day, against about 10% in July and October, the lowest months. That is one of Brownsberg Nature Park's wettest months, with about 300 mm of rain against 55 mm in October. June and August–September have too few records to rate.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Steindachner's Dwarf Frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Brownsberg Nature Park, in our data
Brownsberg Nature Park is the only park on Wallace's Line with enough records to rate Steindachner's Dwarf Frog sightings: about 50% of wildlife watchers there report one on a given day.
Same family: Leptodactylidae
The closest relatives of the Steindachner's Dwarf Frog that you can see in Brownsberg Nature Park (family Leptodactylidae, Southern Frogs) are Knudsen's Thin-toed Frog (about 50%), Guiana White-lipped Frog (about 40%) and Loreto White-lipped Frog (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Steindachner's Dwarf Frog is recorded against all the amphibians logged in Brownsberg Nature Park (16 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.
