In 3 days ~30% in a week ~60%
Psolos fuligo, the dusky partwing or coon, is a species of butterfly belonging to the family Hesperiidae. It is found in India. The tips of the forewings diverge outward and is a feature that is clear when they rest on vegetation.
It is a small butterfly with a wingspan of 36 to 46 millimetres (1.4 to 1.8 in). Both sexes look alike, excepting that the male has a prominent brand on the under forewing. It is a plain brown butterfly on the upperside. Underneath, the butterfly is similarly coloured but paler. There are diffused greyish-purple markings on the tip of the under forewing and a series of pale spots in spaces 4 to 9. Similarly spots can be seen on the under hindwing in spaces 2 to 7 and at the end cell.
The butterfly ranges from India to Southeast Asia and the Indonesian archipelago. India forms the western boundary of the coon with the butterfly found in the Western Ghats in peninsular India, and from Assam to Arunachal Pradesh, other states of the north-east India and into Bangladesh and southern Myanmar. In south-east Asia, the coon flies in Thailand, Malaysia, Singapore, Vietnam, Laos, Philippines, and possibly southern China... Wikipedia →

With luck
About 10% of wildlife watchers report a Dusky Partwing sighting in Kozhikode on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 87th most-seen of the 138 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.
December
In that month about 30% of wildlife watchers report a Dusky Partwing in Kozhikode on a given day, against under 5% in January–June, August and October–November, the lowest months. That is one of Kozhikode's driest months, with about 25 mm of rain against 390 mm in June.
Only Kozhikode, in our data

GBIF citizen-science records
It is estimated from how often the Dusky Partwing is recorded against all the insects logged in Kozhikode (9 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.
