Cruziohyla craspedopus, the fringed leaf frog or fringed tree frog, is a species of frog in the subfamily Phyllomedusinae. It is found in the Amazonian lowlands in Brazil, Colombia, Ecuador, and Peru, and possibly in Bolivia.
Cruziohyla craspedopus can be distinguished from other frogs of Cruziohyla by the following characteristics. Adult males measure 53–66 mm (2.1–2.6 in) and adult females 68–76 mm (2.7–3.0 in) in snout–vent length. The head is slightly wider than it is long. The snout is sharply truncate in lateral view. The fingers and toes are webbed. The hind margin of the tarsus bear extensive dermal appendages forming irregular spurs. The dorsum has uniform dark green dorsal background coloration interspersed with irregular-shaped large pale blue-grey lichenose blotches. The flanks have narrow black lines. The undersides and concealed surfaces of the flanks and legs are yellow. When adhered to a surface, the yellow coloration becomes concealed which can aid in camouflage.
Cruziohyla craspedopus displays a burgundy pigmentation at night. This ability to rapidly color-adapt is mainly caused by levels of the hormone, intermedin, and its effects... Wikipedia →

With luck
About 10% of wildlife watchers report a Fringed Leaf Frog sighting in Manu National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 55th most-seen of the 67 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 Fringed Leaf Frog is recorded against all the amphibians logged in Manu National Park (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.
