Rare
Under 5% of wildlife watchers report a Krananda latimarginaria sighting in Hong Kong on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 467th 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 and December–March
In those months about 10% of wildlife watchers report a Krananda latimarginaria in Hong Kong on a given day, against under 5% in April–May and July–November, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Krananda latimarginaria sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
8th of 9
Of the 9 cities where we can rate Krananda latimarginaria sightings, Hong Kong ranks 8th at under 5%. The best odds are in Suzhou (China, about 10%), Nagoya (Japan, about 10%) and Nanjing (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Krananda latimarginaria is recorded against all the insects logged in Hong Kong (20 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.
