With luck
About 10% of wildlife watchers report a Pink-Spotted Windmill sighting in Taipei on a given day, based on 72 verified sightings from GBIF citizen-science data. It is the 171st most-seen of the 765 insects 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.
March to October
In those months about 10% of wildlife watchers report a Pink-Spotted Windmill in Taipei on a given day, against under 5% in November to February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Pink-Spotted Windmill sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Taipei, in our data
Taipei is the only city on Wallace's Line with enough records to rate Pink-Spotted Windmill sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Pink-Spotted Windmill is recorded against all the insects logged in Taipei (72 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.
