Rare
Under 5% of wildlife watchers report an Ischyja manlia sighting in Hong Kong on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 555th 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.
January, April and October
In those months about 10% of wildlife watchers report an Ischyja manlia in Hong Kong on a given day, against under 5% in February–March, May–September and November–December, the lowest months. Those are among Hong Kong's driest months, with about 65 mm of rain a month against 280 mm in June.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Ischyja manlia sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 4 cities where we can rate Ischyja manlia sightings, Hong Kong has the highest daily chance: under 5%. Next come Bengaluru (India, under 5%) and Guangzhou (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Ischyja manlia is recorded against all the insects logged in Hong Kong (15 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.
