Dendropsophus nanus, commonly known as dwarf treefrog, is a species of frog in the family Hylidae. It is found in northern Argentina, Paraguay, Uruguay, eastern Bolivia, Brazil, French Guiana, and Suriname. It is very common frog occurring in many habitat types and adapting well to anthropogenic disturbance. It inhabits herbaceous vegetation at the edge of standing water. Breeding takes place in temporary waterbodies.
The diet of Argentinean Dendropsophus nanus was found to consist mostly of dipterans and spiders. During the cold periods, these frogs partly rely on their fat reserves, more so than sympatric Hypsiboas pulchellus. Wikipedia →

Possible
About 20% of wildlife watchers report a Dwarf Tree Frog sighting in Campo Grande on a given day, based on 5 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Dwarf Tree Frog in Campo Grande on a given day, against under 5% in February–March and May–October, the lowest months. That is one of Campo Grande's wettest months, with about 180 mm of rain against 30 mm in July.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Dwarf Tree 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.
Yes
Of the 2 cities where we can rate Dwarf Tree Frog sightings, Campo Grande has the highest daily chance: about 20%. Next come Buenos Aires (Argentina, under 5%).
GBIF citizen-science records
It is estimated from how often the Dwarf Tree Frog is recorded against all the amphibians logged in Campo Grande (5 verified sightings), 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.
