With luck
About 10% of wildlife watchers report a Chilkasa falcata sighting in Kinabalu Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 204th most-seen of the 297 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Chilkasa falcata in Kinabalu Park on a given day, against under 5% in June–August and October–March, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Chilkasa falcata sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Chilkasa falcata sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Chilkasa falcata that you can see in Kinabalu Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Asota kinabaluensis (about 20%), Asota heliconia (about 20%) and Lobobasis niveimaculata (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chilkasa falcata is recorded against all the insects logged in Kinabalu Park (7 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.
