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 Kanha National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 81st most-seen of the 106 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.
March
In that month about 40% of wildlife watchers report a Chestnut-Streaked Sailer in Kanha National Park on a given day, against under 5% in April, June–July and September–February, the lowest months. That is one of Kanha National Park's driest months, with about 30 mm of rain against 430 mm in July.
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.
Only Kanha National Park, in our data
Kanha National Park is the only park on Wallace's Line with enough records to rate Chestnut-Streaked Sailer sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Chestnut-Streaked Sailer is recorded against all the insects logged in Kanha National Park (5 verified sightings from 2019 to 2026), 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.
