Rare
Under 5% of wildlife watchers report a Dideopsis aegrota sighting in Hong Kong on a given day, based on 19 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 October–November
In those months about 10% of wildlife watchers report a Dideopsis aegrota in Hong Kong on a given day, against under 5% in July–September and December–May, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Dideopsis aegrota sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 8 cities where we can rate Dideopsis aegrota sightings, Hong Kong has the highest daily chance: under 5%. Next come Tuen Mun (China, under 5%) and Taipei (Taiwan, under 5%).
GBIF citizen-science records
It is estimated from how often the Dideopsis aegrota is recorded against all the insects logged in Hong Kong (19 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.
