Rare
Under 5% of wildlife watchers report a Milionia basalis sighting in Guangzhou on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 269th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Milionia basalis in Guangzhou on a given day, against under 5% in July to April, the lowest months. Those are among Guangzhou's wettest months, with about 300 mm of rain a month against 30 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.
6th of 6
Of the 6 cities where we can rate Milionia basalis sightings, Guangzhou ranks 6th at under 5%. The best odds are in Taipei (Taiwan, about 20%), Zhuhai [Macau] (China, about 20%) and Hong Kong (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Milionia basalis is recorded against all the insects logged in Guangzhou (10 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.
