Rare
Under 5% of wildlife watchers report a Heortia vitessoides sighting in Guangzhou on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 230th 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 Heortia vitessoides 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 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Heortia vitessoides sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
4th of 4
Of the 4 cities where we can rate Heortia vitessoides sightings, Guangzhou ranks 4th at under 5%. The best odds are in Tuen Mun (China, about 10%), Hong Kong (China, about 10%) and Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 10%).
GBIF citizen-science records
It is estimated from how often the Heortia vitessoides is recorded against all the insects logged in Guangzhou (12 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.
