In 3 days ~40% in a week ~70%
Euphaea formosa, the Formosan damselfly, is a species of damselfly in the family Euphaeidae. It is common in Taiwan. There is a single historical record from Xiamen, China as Euphaea compar, though this 19th-century specimen was likely mislabeled; today the species is considered endemic to Taiwan.
The IUCN conservation status of Euphaea formosa is 'least concern', with no immediate threat to the species' survival. Wikipedia →

With luck
About 10% of wildlife watchers report a Formosan Damselfly sighting in Taroko National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 111th most-seen of the 447 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June–September and November
In those months about 20% of wildlife watchers report a Formosan Damselfly in Taroko National Park on a given day, against under 5% in May and December–March, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Formosan Damselfly sightings with a recorded time, and nearly all 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 Formosan Damselfly sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Formosan Damselfly is recorded against all the insects logged in Taroko National Park (18 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.
