Cleora alienaria
In 3 days ~10% in a week ~30%
Cleora alienaria is a moth of the family Geometridae first described by Francis Walker in 1860. It is found in Sri Lanka, the Indian subregion to the Andaman Islands, Thailand, Sundaland, Taiwan, and Lesser Sundas as far east as Timor and Christmas Island.
Adults are polymorphic and show clear color differences; this leads to confusion of classification. The discal spot of the forewing is clearly defined. The caterpillar is a leafy green color with fine linear marbling. There is a narrow, lenticular, transverse white bar anterior to dorsolateral brown tubercles. This white bar is divided centrally by a black triangle. The caterpillar is known to feed on Falcataria moluccana, Acacia mangium, Cinnamomum, Sambucus, and Dalbergia monetaria.
Three subspecies are recognized. Wikipedia →

Rare
Under 5% of wildlife watchers report a Cleora alienaria sighting in Hong Kong on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 506th 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.
April and May
In those months about 10% of wildlife watchers report a Cleora alienaria in Hong Kong on a given day, against under 5% in June to March, the lowest months.
Yes
Of the 2 cities where we can rate Cleora alienaria sightings, Hong Kong has the highest daily chance: under 5%. Next come Taipei (Taiwan, under 5%).
GBIF citizen-science records
It is estimated from how often the Cleora alienaria is recorded against all the insects logged in Hong Kong (21 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.
