In 3 days ~30% in a week ~60%
Gangara thyrsis, commonly known as the giant redeye, is a species of butterfly belonging to the family Hesperiidae. It breeds on a number of palm species. The male and female are dark chocolate brown. With a forewing consisting of bright yellow semi-transparent quadrate spots disposed triangularly, the first is large and occupying half the cell, the second also large, obliquely beneath and partly beyond, the third small and obliquely above the second; above the last are three smaller spots obliquely before the apex, the two upper being geminated; in some specimens beneath the subapical spots is a small dot, and on the posterior margin another, both similar to the rest; cilia at posterior angle brownish-white; hindwing with the cilia at the anterior angle brownish white. Underside, forewing irrorated (sprinkled) with grey scales near the apex, posterior margin pale brownish-white, spots yellow as above; hindwing irrorated with grey scales in a series of bands across the wing.
The male of this species presents, on the upperside of each anterior wing, three lines of modified scales, namely, one along the posterior side of the median vein between the origins of its first... Wikipedia →

With luck
About 10% of wildlife watchers report a Giant Redeye sighting in Kochi on a given day, based on 60 verified sightings from GBIF citizen-science data. It is the 80th most-seen of the 428 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June, September and December
In those months about 20% of wildlife watchers report a Giant Redeye in Kochi on a given day, against under 5% in February, the lowest month.
Among the best
Of the 7 cities where we can rate Giant Redeye sightings, Kochi ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Thiruvananthapuram (India, about 10%).
Same family: Hesperiidae
The closest relatives of the Giant Redeye that you can see in Kochi (family Hesperiidae, Skippers) are Chestnut Bob (about 20%), Common Awl (about 20%) and Indian Palm Bob (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Giant Redeye is recorded against all the insects logged in Kochi (60 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.
