Rare
Under 5% of wildlife watchers report an African Joker sighting in Durban on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 248th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–April and June–July
In those months about 10% of wildlife watchers report an African Joker in Durban on a given day, against under 5% in May and August–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.
2nd of 2
Of the 2 cities where we can rate African Joker sightings, Durban ranks 2nd at under 5%. The best odds are in Kampala (Uganda, about 10%).
GBIF citizen-science records
It is estimated from how often the African Joker is recorded against all the insects logged in Durban (8 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.
