Elymnias caudata
In 3 days ~50% in a week ~80%
Elymnias caudata, the tailed palmfly, is a species of satyrine butterfly found in South India. Some authors consider this as a subspecies of Elymnias hypermnestra. This butterfly species are sexually dimorphic: males and females do not look alike. Males have black upperside forewings with small blue patches and mimic Euploea species, while the females mimic butterfly species of the genus Danaus.
Both sexes have the wings longer, proportionately to their breadth, and the tail at apex of vein 4 on the hindwing longer compared to Elymnias hypermnestra. Upperside: Male differs from E. hypermnestra as follows: the subterminal and preapical spots on the forewing white suffused slightly with dark scales; the terminal half of the hindwing tawny, more or less suffused with dusky black, which in some specimens forms a distinct border along the termen. Female similar to the female of E. hypermnestra, but the black more extended; veins 2, 3, and 4 on the hindwing broadly bordered with black.
Underside: Female differs from E. hypermnestra in the more conspicuous broadly triangular white pre-apical patch on the forewing, and in the prominence of the broad tawny terminal half of... Wikipedia →

Possible
About 20% of wildlife watchers report a Tailed Palmfly sighting in Kochi on a given day, based on 150 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 428 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Tailed Palmfly in Kochi on a given day, against about 10% in November to May, the lowest months.
6th of 10
Of the 10 cities where we can rate Tailed Palmfly sightings, Kochi ranks 6th at about 20%. The best odds are in Kozhikode (India, about 40%), Thiruvananthapuram (India, about 40%) and Ponnani (India, about 30%).
Same family: Nymphalidae
The closest relatives of the Tailed Palmfly that you can see in Kochi (family Nymphalidae, Brush-footed Butterflies) are Common Crow (about 30%), Grey Pansy (about 30%) and Common Evening Brown (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tailed Palmfly is recorded against all the insects logged in Kochi (150 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.
