Cleora alienaria
In 3 days ~10% in a week ~20%
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 Taipei on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 570th most-seen of the 765 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Cleora alienaria in Taipei on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Cleora alienaria sightings, Taipei ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Hong Kong (China, under 5%).
Same family: Geometridae
The closest relatives of the Cleora alienaria that you can see in Taipei (family Geometridae, Geometer Moths) are Milionia basalis (about 20%), Eumelea ludovicata (about 10%) and Asian Cross-Lined Wave Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cleora alienaria is recorded against all the insects logged in Taipei (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.
