Rare
Under 5% of wildlife watchers report a Sullied Brown Sailer sighting in Hong Kong on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 429th most-seen of the 1125 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.
June–August and November
In those months about 10% of wildlife watchers report a Sullied Brown Sailer in Hong Kong on a given day, against under 5% in September–October and December–May, the lowest months. Those are among Hong Kong's wettest months, with about 180 mm of rain a month against 25 mm in December.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Sullied Brown Sailer sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Sullied Brown Sailer sightings, Hong Kong ranks 3rd at under 5%. The best odds are in Taipei (Taiwan, about 10%) and Taichung (Taiwan, about 10%).
Same genus: Neptis
The closest relatives of the Sullied Brown Sailer that you can see in Hong Kong (genus Neptis, Typical Sailers) are Common Sailer (about 20%) and Southern Sullied Sailer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sullied Brown Sailer is recorded against all the insects logged in Hong Kong (23 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.
