With luck
About 10% of wildlife watchers report an Ischyja ferrifracta sighting in Hong Kong on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 352nd 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.
February, June and August–November
In those months about 10% of wildlife watchers report an Ischyja ferrifracta in Hong Kong on a given day, against under 5% in March–May, July and December–January, the lowest months.
Among the best
Of the 2 cities where we can rate Ischyja ferrifracta sightings, Hong Kong ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Taipei (Taiwan, about 10%).
GBIF citizen-science records
It is estimated from how often the Ischyja ferrifracta is recorded against all the insects logged in Hong Kong (27 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.
