Rare
Under 5% of wildlife watchers report a Hemithea tritonaria sighting in Hong Kong on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 731st 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.

GBIF citizen-science records
It is estimated from how often the Hemithea tritonaria is recorded against all the insects logged in Hong Kong (10 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.
