With luck
About 10% of wildlife watchers report a Drury's Jewel sighting in Hong Kong on a given day, based on 62 verified sightings from GBIF citizen-science data. It is the 178th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April–July and September
In those months about 10% of wildlife watchers report a Drury's Jewel in Hong Kong on a given day, against under 5% in August and October–March, the lowest months. Those are among Hong Kong's wettest months, with about 190 mm of rain a month against 25 mm in December.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Drury's Jewel sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 4 cities where we can rate Drury's Jewel sightings, Hong Kong ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Drury's Jewel is recorded against all the insects logged in Hong Kong (62 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.
