Neptis jumbah
In 3 days ~40% in a week ~70%
Neptis jumbah, the chestnut-streaked sailer, is a species of nymphalid butterfly found in South Asia. The male somewhat resembles Neptis columella, but differs as follows: Upperside fuliginous black, the interspaces between the veins deeper black, very conspicuous in certain lights, particularly so between the subbasal and postdiscal markings on the hindwing; the white markings suffused with very pale bluish green; the posterior two spots of the discal series on the forewing subequal; the postdiscal macular band on the hindwing with a tendency to obsolescence, varying from a narrow series of white lunules to a somewhat diffuse transverse narrow pale band. On the underside the ground colour is paler than in N. columella, the interspaces between the veins conspicuously much darker; the postdiscal and subterminal markings on both forewings and hindwings diffuse and very ill-defined. N. jumbah can also be recognized by the discal transverse series of comparatively large dark brown spots.
In the female the spots on the forewing and the subbasal band on the hindwing are comparatively broader than they are in the male; in the dry-season form of both sexes, as compared with... Wikipedia →

With luck
About 10% of wildlife watchers report a Chestnut-Streaked Sailer sighting in Kochi on a given day, based on 82 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 428 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May–July and September
In those months about 20% of wildlife watchers report a Chestnut-Streaked Sailer in Kochi on a given day, against about 10% in August and October–April, the lowest months. Those are among Kochi's wettest months, with about 380 mm of rain a month against 15 mm in January.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Chestnut-Streaked Sailer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 7 cities where we can rate Chestnut-Streaked Sailer sightings, Kochi has the highest daily chance: about 10%. Next come Bengaluru (India, about 10%) and Kozhikode (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Chestnut-Streaked Sailer is recorded against all the insects logged in Kochi (82 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.
