Dichorragia nesimachus
In 3 days ~10% in a week ~20%
Dichorragia nesimachus, the constable, is a species of nymphalid butterfly found in Asia. The genus was earlier considered to belong to the subfamily Cyrestinae and sometimes the Apaturinae, but is now considered as a sister of the genus Stibochiona in the subfamily Pseudergolinae. Several geographical forms with variations in colour are noted within the wide distribution range extending from India in the west to Japan in the east. In Vietnam, it is thought to show hill topping behaviour and is typically found in dense forest habitats. They may also be found mud puddling with other species.
A closely related species Dichorragia ninus is found in New Guinea and surrounding islands although some authors include it as a subspecies of D. nesimachus. D. n. nesimachus (Sikkim, Bhutan, Assam, Manipur - Indochina, South Yunnan) Wikipedia →

Rare
Under 5% of wildlife watchers report a Constable sighting in Taipei on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 396th 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.
April and June
In those months about 10% of wildlife watchers report a Constable in Taipei on a given day, against under 5% in May and July–March, the lowest months.
2nd of 3
Of the 3 cities where we can rate Constable sightings, Taipei ranks 2nd at under 5%. The best odds are in Nanjing (China, about 10%).
Same family: Nymphalidae
The closest relatives of the Constable that you can see in Taipei (family Nymphalidae, Brush-footed Butterflies) are Common Mapwing (about 20%), Common Palmfly (about 20%) and Great Eggfly (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Constable is recorded against all the insects logged in Taipei (17 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.
