With luck
About 10% of wildlife watchers report an African Joker sighting in Kampala on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 33rd most-seen of the 42 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.

In that month about 30% of wildlife watchers report an African Joker in Kampala on a given day, against under 5% in April and June–February, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most African Joker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Same family: Nymphalidae

GBIF citizen-science records
It is estimated from how often the African Joker is recorded against all the insects logged in Kampala (5 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.
