In 3 days ~90% in a week >90%
Cirrochroa aoris, the large yeoman, is a species of nymphalid butterfly found in forested areas of tropical South Asia and Southeast Asia. It is very similar to Cirrochroa tyche. There are slight differences in wing shape (more irregular/toothed in aoris), ground colour variations (brown/blue hues in aoris), and distinctive markings, often requiring close inspection of wing spots and edges.

Likely
About 60% of wildlife watchers report a Large Yeoman sighting in Namdapha National Park on a given day, based on 46 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 71 insects we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
October
In that month about 80% of wildlife watchers report a Large Yeoman in Namdapha National Park on a given day, against about 10% in February, the lowest month. June to August have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Large Yeoman sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Namdapha National Park, in our data
Namdapha National Park is the only park on Wallace's Line with enough records to rate Large Yeoman sightings: about 60% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Large Yeoman is recorded against all the insects logged in Namdapha National Park (46 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.
