In 3 days ~10% in a week ~30%
Mycalesis subdita, the Tamil bushbrown, is a satyrine butterfly found in south India and Sri Lanka. It is not resolved whether this is a good species or is a subspecies of Mycalesis visala. Closely resembles in both seasonal forms Mycalesis mineus. The male can be discriminated by the sex-mark on the underside of the forewing: this is brown or ochraceous brown as in M. perseoides but very much longer and broader, extending to but not going beyond the transverse band crossing the wings.
Wet-Season Brood: Male and female. Upperside dark olivescent ochreous-brown, with a very faint pale transverse discal narrow fascia, and distinctly paler marginal lines; both most apparent in the female. Cilia cinereous-ochreous. Forewing more rounded at the apex than in Mycalesis visala; with a large prominent median ocellus. Hind-wing with one, occasionally two, small slightly defined median ocelli. Underside dark greyish ochreous-brown or fuliginous-brown; with a well-defined whitish transverse discal band, and marginal ochreous lines. Forewing with one small subapical ocellus and two conjoined lower median ocelli, the latter pair being disposed one between the middle and lower... Wikipedia →

With luck
About 10% of wildlife watchers report a Tamil Bushbrown sighting in Chennai on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 259th most-seen of the 376 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and October–January
In those months about 10% of wildlife watchers report a Tamil Bushbrown in Chennai on a given day, against under 5% in February–March and May–September, the lowest months.
Among the best
Of the 2 cities where we can rate Tamil Bushbrown sightings, Chennai ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Bengaluru (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Tamil Bushbrown is recorded against all the insects logged in Chennai (8 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.
