Rare
Under 5% of wildlife watchers report a Restricted Demon sighting in Guangzhou on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 355th 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 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Restricted Demon in Guangzhou on a given day, against under 5% in August to June, the lowest months. That is one of Guangzhou's wettest months, with about 210 mm of rain against 30 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Restricted Demon sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Restricted Demon sightings, Guangzhou ranks 4th at under 5%. The best odds are in Taipei (Taiwan, about 10%), Tuen Mun (China, about 10%) and Hong Kong (China, about 10%).
Same family: Hesperiidae
The closest relatives of the Restricted Demon that you can see in Guangzhou (family Hesperiidae, Skippers) are Indian Palm Bob (about 10%), Grass Demon (about 10%) and Pale Awlet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Restricted Demon is recorded against all the insects logged in Guangzhou (7 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.
