Rare
Under 5% of wildlife watchers report a Tea Looper sighting in Hong Kong on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 613th 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 September
In those months about 10% of wildlife watchers report a Tea Looper in Hong Kong on a given day, against under 5% in April–August and October–February, the lowest months.
3rd of 3
Of the 3 cities where we can rate Tea Looper sightings, Hong Kong ranks 3rd at under 5%. The best odds are in Kochi (India, about 10%) and Bengaluru (India, under 5%).
Same family: Geometridae
The closest relatives of the Tea Looper that you can see in Hong Kong (family Geometridae, Geometer Moths) are False Tiger Moth (about 30%), Milionia basalis (about 10%) and Orange Magpie Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tea Looper is recorded against all the insects logged in Hong Kong (13 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.
