Rare
Under 5% of wildlife watchers report a Dichromia sagitta sighting in Hong Kong on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 680th 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 20%, if each day is a fresh chance.
March and June
In those months about 10% of wildlife watchers report a Dichromia sagitta in Hong Kong on a given day, against under 5% in April–May and July–February, the lowest months. Those are among Hong Kong's wettest months, with about 180 mm of rain a month against 25 mm in December.
2nd of 2
Of the 2 cities where we can rate Dichromia sagitta sightings, Hong Kong ranks 2nd at under 5%. The best odds are in Chennai (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Dichromia sagitta is recorded against all the insects logged in Hong Kong (11 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.
