With luck
About 10% of wildlife watchers report a Milionia basalis sighting in Taichung on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 48th most-seen of the 197 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
May–June and November
In those months about 20% of wildlife watchers report a Milionia basalis in Taichung on a given day, against about 10% in July–October and December–April, the lowest months. Those are among Taichung's wettest months, with about 200 mm of rain a month against 40 mm in December.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Milionia basalis sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 6
Of the 6 cities where we can rate Milionia basalis sightings, Taichung ranks 4th at about 10%. The best odds are in Taipei (Taiwan, about 20%), Zhuhai [Macau] (China, about 20%) and Hong Kong (China, about 10%).
Same order: Lepidoptera
The closest relatives of the Milionia basalis that you can see in Taichung (order Lepidoptera, Butterflies and Moths) are Pale Grass Blue (about 40%), Lime Swallowtail (about 30%) and Small White (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Milionia basalis is recorded against all the insects logged in Taichung (22 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.
