Zhangixalus moltrechti is a species of frog in the family Rhacophoridae. It is endemic to Taiwan, where it has a wide distribution in hilly areas. Common names Moltrecht's green treefrog, Moltrecht's treefrog, Taiwan treefrog, and Nantou flying frog have been coined for it.
The specific name moltrechti honors Arnold Moltrecht, a Latvian entomologist, lepidopterist, and ophthalmologist; while stationed in Vladivostok he also traveled and collected in Taiwan. Zhangixalus moltrechti is a medium-sized tree frog, females are 5–6 cm (2.0–2.4 in) in snout-vent length; males are slightly smaller, 3.6–4.2 cm (1.4–1.7 in). The finger and toe tips have well-developed discs. Skin is smooth. The overall coloration is green; some individuals have few white spots. The belly is white yellow. The hidden surfaces of the hind legs are red or orange with black spots. The iris is orange red.
Zhangixalus moltrechti occurs in forests, orchards, and tea plantations between 0 and 2500 meters above sea level. Breeding takes place in bodies of standing water, such as ponds, pools, cisterns, and blocked roadside ditches. The female frog lays eggs... Wikipedia →

Possible
About 30% of wildlife watchers report a Moltrecht's Green Tree Frog sighting in Taroko National Park on a given day, based on 35 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 8 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.
April–May and November–December
In those months about 40% of wildlife watchers report a Moltrecht's Green Tree Frog in Taroko National Park on a given day, against under 5% in September and October, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Moltrecht's Green Tree Frog sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Taroko National Park, in our data
Taroko National Park is the only park on Wallace's Line with enough records to rate Moltrecht's Green Tree Frog sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Moltrecht's Green Tree Frog is recorded against all the amphibians logged in Taroko National Park (35 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.
